View raw code

Before uploading the code, you need to insert your network credentials in the following variables:

const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";

Then, make sure you select the right camera module. In this case, we’re using the AI-THINKER Model.

ESP32-CAM camera board AI Thinker module CAMERA_MODEL_AI_THINKER

If you’re using the same camera module, you don’t need to change anything on the code.

#define CAMERA_MODEL_AI_THINKER

Now, you can upload the code to your ESP32-CAM board.

3. Uploading the Code

Connect the ESP32-CAM board to your computer using an FTDI programmer. Follow the next schematic diagram:

ESP32-CAM connected to an FTDI Programmer to upload program using Arduino IDE

Many FTDI programmers have a jumper that allows you to select 3.3V or 5V. Make sure the jumper is in the right place to select 5V.

Important: GPIO 0 needs to be connected to GND so that you’re able to upload code.

ESP32-CAMFTDI Programmer
GNDGND
5VVCC (5V)
U0RTX
U0TRX
GPIO 0GND

To upload the code, follow the next steps:

1) Go to Tools > Board and select AI-Thinker ESP32-CAM.

2) Go to Tools > Port and select the COM port the ESP32 is connected to.

3) Then, click the upload button to upload the code.

4) When you start to see these dots on the debugging window as shown below, press the ESP32-CAM on-board RST button.

ESP32-CAM camera board upload new Arduino IDE sketch press RESET button

After a few seconds, the code should be successfully uploaded to your board.

Getting the IP address

After uploading the code, disconnect GPIO 0 from GND. Open the Serial Monitor at a baud rate of 115200. Press the ESP32-CAM on-board Reset button.

The ESP32 IP address should be printed in the Serial Monitor.

Home Assistant Integration

Having just the ESP32-CAM working via IP might be useful for most people, but you can integrate this project with Home Assistant (or with other home automation platforms). Continue reading to learn how to integrate with Home Assistant.

Prerequisites

Adding ESP32-CAM to Home Assistant

Open your Home Assistant dashboard and go to the more Settings menu.

ESP32-CAM camera board IP address web Server IP CAM home assistant integration

Open Configure UI:

ESP32-CAM camera board IP address web Server IP CAM configure UI

Add a new card to your Dashboard:

ESP32-CAM camera board home assistant add new element

Pick a card of the type Picture.

ESP32-CAM camera board home assistant Picture card

In the Image URL field, enter your ESP32-CAM IP address. Then, click the “SAVE” button and return to the main dashboard.

Tip: Node-RED Integration

The video streaming web server also integrates with Node-RED and Node-RED Dashboard. You just need to create a Template node and add the following:

<div style="margin-bottom: 10px;">
<img src="https://YOUR-ESP32-CAM-IP-ADDRESS" width="650px">
</div>

In the src attribute, you need to type your ESP32-CAM IP address:

<div style="margin-bottom: 10px;">
<img src="https://192.168.1.91" width="650px">
</div>

    • Yes. We intend to integrate this with Node-RED too.
      The face recognition and triggering events might be a bit more difficult. We’ll see…

          • Hi Sara,

            I have three ESP 32 cams that I am having trouble with. When I reset them they will work for 8 to 10 hours. After that they will be still online (ping OK) but their web servers stop responding. The message is:

            This site can’t be reached
            192.168.1.196 took too long to respond.

            Try:
            Checking the connection
            Checking the proxy and the firewall
            Running Windows Network Diagnostics

            ERR_CONNECTION_TIMED_OUT

            The only way to get them working again is to reset them or cycle the power. It will then work for 1 to 3 days and hang up again.

            I tried one of your sketches at first, then switched to the sketch in the Arduino examples (the one with all the camera controls). No improvement.
            I have three of these cams and sometimes they all stop working together, or sometimes one at a time.

            I tried inserting code in the LOOP() to reconnect to WiFi and then to start the web server every 10 seconds (10 second delay already in there) but this made it worse.

            Do you have any idea how I can troubleshoot this? Maybe put in code to make them reboot once a day or something like that? Maybe there is a memory leak somewhere? My “ESP8266 with BME 280” (which also has a web server) is much more reliable.

            I would appreciate your thoughts on this.

            Thank you

            Mike.

          • Hi Carlos,
            I have three ESP32-CAM boards and I have a problem occasionally where I cannot get a still or stream. The response is:
            This page isn’t working
            192.168.1.196 didn’t send any data.
            ERR_EMPTY_RESPONSE
            If I PING the board’s IP address, I almost always get a normal ping response, but still cannot see the camera. I have to reset or cycle power to restore operation.
            The other day, all three became unavailable together.
            I tried your sketch, then another sketch with all the camera controls. Same problem.
            I put in some code to reconnect to WiFi in case it disconnects, but that did not help.
            I also have an ESP8266 Weather station with BME280 and that always works (maybe I had to reset it once in the past six months).
            What do you think I can do to fix this problem?

  1. I meant completely integrating it in Node-RED – available on the dashboard as a viewable feed, face recognition triggering events, etc.

  2. I’d like to create a battery powered version that uses the ESP32’s deep sleep mode (with motion detection to wake it up) and low battery notifications.

      • I am looking forward to the motion detection function. Now I am connect to motioneye by your code, but I can’t open my flashlight on esp32-cam. I have two choice, one is open it by motion detector on board. The other one is open it by HA. Unfortunately, I think HA can’t contorl esp32 IO out of esphome. Could you give me some suggestion?

        • The built in LED is meant for a flash, it will get very hot if used continuously. If you can find the pinout, then you just control the LED like you would any other.

  3. Dear Sir,
    That’s a lovely project.

    However, I’m not getting the some of the header files used in the arduino sketch. They are esp_camera.h, “esp_http_server.h”,
    esp_timer.h,img_converters.h

    Can you please be kind enough to help me getting these header files?

    Thanks in advance..

  4. Fantastic! Any suggestions on how to use it to capture video? IE: if it could detect motion with a passive IR added in addition to the ESP32 camera…and that motion could trigger the local PC to record for X minutes, that would be FANTASTIC.

      • Hi Sara,

        Most excellent! I look forward to it. Got several of the boards on the way. I’m thinking that instead of putting the board into a security camera housing, I’m going to mount it to the inside of a window facing to the outside. Should work well and not require any environmental sealing. 🙂

        Thanks much,

    How difficult would it be to adapt the face recognition SW to learn to recognize objects?

    Thanks to you and Sara for all the information and work you do to educate people.

    • Hi Lloyd.
      At the moment, I don’t think it is easy to do that with the ESP32-CAM and arduino IDE. It’s a quite new topic and there aren’t many libraries available to do that.
      There are much more support for object recognition using raspberry pi and its camera at the moment.

  7. HI, I’m using this esp32 camera from M5Stack-Camera-Antenna-Arduino-Raspberry

    When the code executes this line:
    fb = esp_camera_fb_get();
    it never returns. I’ve place a Serial.println() before and after the line, and the line after never prints out.

    The only camera model setting that passes the camera init and probe is this: CAMERA_MODEL_M5STACK_PSRAM.

    Here are the things that I’ve tried:
    — created OV2640 config : fails camera init and probe
    — changed jpeg_quality making from a Min of 1 to a max of 12
    — Changed fb_count numbers 1-3

    What would you suggest?

    Thanks in advance,

        This project is awesome. I would like to know if you can access the ESP32Cam from another device (cellphone etc) that is connected to another WiFi server.

        • Hi Magdalena.
          What do you mean by “it is connected to another WiFi server”?. I’m not sure if I understood your question.
          In this particular example, to access the video streaming you need to be connected to the same network that the ESP32-CAM is connected to.
          Regards,

        • Yes, that would be possible in a number of ways. You could use a VPN to connect your phone to the network, you could stream from the ESP32-CAM to a proxy server in the cloud, or you could set up port forwarding on your firewall. These, however, are general networking questions.

          • I’ve used the free version of Netcam Studio X for a long time with this project and six ESP32 cams. Two cameras are in the clear on the free version. You can still have as many as you like, but the others have a watermark across their images. I can view them all on the local network or from anywhere in the world using the Studio X app on my phone

          • Hi Sara

            Quite a lot of features and simple to set up. Works reliably, and doesn’t gobble a lot of local resources. I went through trying a lot of camera remote viewing / streaming apps with very limited and variable results before finding this one. The local server can run as a background service, so will auto-start with the computer. As well as having the app to view the cameras from anywhere on your phone, there is also a local ‘client’ app that allows you to view all the cameras on the host computer

  8. Hello.
    When I try to upload the sketch to the ESP32 CAM an error mesagge shows “Failed to connect to ESP32: Timed out waiting for packet header”.
    I’ve checked the connections, pressed Reset before and during the upload attempt, connected to 3.3v and 5v, used //#define CAMERA_MODEL_WROVER_KIT and #define CAMERA_MODEL_AI_THINKER.
    Please, I’ll be glad to know if you have any suggestions of something else to try.
    Best wishes.

    • Hi Marcelo.
      I’m sorry you’re having trouble with your board.
      Please verify that you have the ESP32 GPIO0 connected to GND during the uploading.
      Also, make sure that in the arduino ide settings, you select Tools > Partition Scheme, select “Huge APP (3MB No OTA)“.
      It this doesn’t work, it is very difficult for me to understand what might be wrong.

  9. Wow, what a brilliant, inspiring idea !!!

    Just last week I received some of these camera’s. I ordered them from China some time ago, but it took some time before they were shipped.
    (I guess they are very popular)

    Yesterday I assembled and programmed the ESP-CAM and found out that it works well when you use a powerbank, you can just walk around with it !
    (also found out that you can program the board with a USB-to-TTL module model CP2102 and that the CH340 model does NOT work)
    Then I searched the whole house for my old dummy camera’s..
    and found them today, haha. They are not as easy to use as yours,
    but some are ‘workable’.

    Surprisingly enough, I managed to build my first dummy-ESP-CAM today !
    I use it to watch my front door, it’s battery operated (3xAA-rechargable-2000mAh) and it works very well !
    They is some (a few seconds) time-lag (latency ?) between what happens and it showing up on screen, but other than that the camera works fine and I love that I can see who’s at my front door before I open it !
    Now we will have to learn by experience how long these batteries will last…

    Your explanation was very easy to follow and my ESP-CAM was up and running before I knew it…. getting it into my old dummy-cam was (a lot) more work…

    Thank you again, for another inspiration ! I had a great day building it !

    • Hi Gerrit,

      I was quite interesting what you have done. Can I know how you regulated the input voltage from 3AA batteries? I assume they were either 3.6 (1.2v3) or 4.5 (1.5v3). Did you supply current directly to 3v3 pin or some regulated manner? Thanks in advance!

      P.S.
      Thank you RNT for the amazing article.

      Cheers

  10. I ordered the components from Maker Advisor but received an unknown model of the ESP32CAM, with which none of the three camera settings work. Since the serial monitor reports: “[D][esp32-hal-psram.c:47] psramInit(): PSRAM enabled”
    I guessed this must be the M5STACK_PSRAM model, but booting with this setting sends the error message “Camera init failed with error 0x20001”.

    The WROVER_KIT setting als returns these errors: “SCCB_Write [ff]=01 failed; SCCB_Write [12]=80 failed; Camera init failed with error 0x20001”

    And the AI_THINKER setting complains about an illegal instruction, reboots and then gives no more information after the “PSRAM enabled” message.

    Any ideas?

  12. Rui,

    I purchased three ESP32-CAM modules from Banggood with camera.

    I have tried everything I could find on internet to program anything on them. I keep getting “Timed out waiting for packet header” error. Nothing ever get programmed? Even used an external power supply and nothing works.

    These modules do not say “AI-THINKER” on them. Might be a different module but cannot prove it this way.

    Any more ideas:

      That error means that your ESP is not in flashing mode.
      Please check that you’ve wire the RX and TX pins properly to the FTDI programmer, and that the ESP32 GPIO0 is connected to GND.

        I have TX going to RX etc. and GPI0 going to gnd. I press boot buton before programming and serial says “waiting for download”. How can I know if ESP32 in flashing mode?

        Tried every mode possible and same result.

        The programmer works ok on other standard ESP32 modules.

      • Hi, I purchased one of these little guys about six months ago, I was playing with it, and suddenly, it stopped working. I have tried to reprogram it, but to no avail, so due to the relativly low price and my love for everything esp related, I ordered another from Banggoods, where I got my first. The second one programs like a dream and works fine, even recognizes me now, so I figured I had the problem licked, I dug out my old one and still no luck. I am guessing some of my playing around probably nuked the board on the first one. It will go in my parts drawer I think for future fun and games as I progress with my knowledge of these little guys, or perhaps till the ESP64 comes out.

          • Hi.
            That means the code was successfully uploaded.
            Disconnect GPIO 0 from GND, open the Serial Monitor and press the ESP32-CAM on-board RESET button to get its IP address.
            Then, you just need to open a browser and type the ESP32-CAM IP address.

      That error means that the ESP32 is not in flashing mode.
      You have to follow the exact same instructions we have in our tutorial.
      By what you’re describing, it seems that you’re doing everything right. If you’re doing as we describe in our tutorial and it doesn’t work, I don’t know what can be the problem.

      Also, as Richard said “If you are using Windows in the Control Panel check to make sure you have a good Driver for the COM port you are using try updating the driver.”

      I’m sorry that I can’t help much. Meanwhile, if you find out the problem let us know. We’re planning to write a troubleshooting guide for the ESP32-CAM.

          • After flashing, you need to remove the connection between GND and IO0. If you see the error (below) – that indicates the ESP-32 is in boot mode, try adding a 10K resistor between IO0 and 3.3V to make sure the state of this pin/input isn’t floating. Once I added the resistor, everything worked for me!

  18. I too received boards with a different chip from Bang Good, however mine work fine with the AI Thinker selection. I did have issues in the beginning when setting them up and finally figured out they are really picky about their power. They need a lot and are extremely intolerant of noise or low voltage. Try using the 5V pin and the ground next to it rather than the 3.3V. They seem to be happier when using their own onboard voltage converter.

    Reply
  19. I too received a unmarked unit from banggood (also 1 from AliExpress) and had the same error, Camera init failed with error 0x20001. But as an earlier poster said, I too switch the jumpier from 3.3v to 5v and that solved the problem.

    NOTE: both my units, were unmarked (images on websites showed AI-Thinker) but required 5 volts. So that was the problem not anything in the code.

  25. Gave up on using the non ‘AI Thinker’ boards and bought another one that was marked AI Thinker…uploaded the code, and finally got the message showing the IP address in the monitor, but no web server on the same LAN!

    Tried a reboot and even reloading the code but get garbage in the monitor and sometimes a message about ‘Camera init failed with error 0x20002’

    I have tried disconnecting the power to the board and connecting 5v and GND instead but get the same results, reflashing the firmware (with 3.3v connected) but nothing…did you ever produce the help guide?

    Reply
    • Hey, try reflashing with 5V (connect to the 5V pin of course). Programming with 3.3V here has also resulted in tons of error messages. With 5V flashing&running, everything is find.

      Reply
      • I just got one and followed the instructions and had problems programming.
        I connected to the 5v line and it programed ok.
        I since realised that my FTDI programer outputs 5 volts ONLY on the VCC line. It can switch between 3.3v and 5v only on the DATA lines.
        I was therefore pumping 5v directly to the 3.3v line, so was lucky not to damage the EPS32 or camera.
        Actually, I may have as there are lots of moving horizontal lines on the image and both camer and EPS32 get very hot.
        Many people suggest bumping up the power to help remove many of the lines, but I wonder how many tried to program with 5v onto the 3.3v line at the begining!

  26. Hi and thanks for the tutorial. Really needed it!
    Took a while to get everything working.
    My main problems were power issues as well.
    I found I could flash the code via USB at 3.3 and 5, but then trying to run the code would constantly crash in different ways.
    So I powered the device with an external 5v power supply, disconnected the USB power (but not the ground). With that, everything worked great.
    Don’t give up on this device … it’s really impressive once you get it going!
    Thanks again for your article!

  30. Hi, Once again another fantastic tutorial which help me enormously. I got it working after changing to the 5v connections and was a little disappointed with the picture lag. I managed to overcome this by changing the: ‘config.frame_size = FRAMESIZE_UXGA;’ to: VGA (config.frame_size = FRAMESIZE_VGA;). The picture quality is not as sharp but it is much more responsive. Also, this camera works with the motion eye os setup. A much cheaper alternative to the pi-zero option with camera. Thanks.

  31. Hi Sara and Rui
    I too got an unmarked ESP32 cam board from China and set it up as an AI Thinker following your excellent tutorial. I was originally running it on 3.3 volts via the USB adaptor board and although it flashed and worked just fine, it was a bit iffy at connecting to the wifi network and there was a lot of latency and coloured lines across the picture. I have now changed to a stand alone 5 volt supply and it is much much better, so it would seem that these unbranded Chinese boards want to run at 5 volts. On a slightly different note, I would really like one of my external camera viewer apps to be able to ‘see’ this camera. I should be able to integrate it manually from the network IP address, port numbers involved and if I know the format of the video stream. Do you happen to know what it is and what port I would need to be looking for / forwarding ?

      • Thanks Sara. I’m going away for a few days so won’t get an opportunity to try anything for a while. Is it possible to have more than one of these camera modules loaded with the tutorial software, running at once ? The router would presumably issue a different IP address to each module but would it just produce a conflict on port 80 ? Sorry if these are dumb questions, but I’m very new to all this. I have several remote viewer apps that I have tried to use with this module but I have been unable so far to get any of them to ‘see’ the module. The apps all seem to have settings for ‘generic’ IP cameras, but there are a lot of them. Is there anything else about the format of the data other than “MJPEG” that’s known that would help me find a setting that allowed the camera to be recognised ? Aircam is the app I would like to use as this works fine with my existing USB cameras and is able to operate with IP cameras as well if you can get them recognised. Thanks again for the excellent tutorials and taking the time to help old dinosaurs like me ! 🙂

  32. Hi, I’ve just got my esp32-cam and managed to make it work in no time, thanks to your explantion – thanks!
    Just wondering about the camera – the picture quality is pretty low – it needs lots of light and I have blue and yellow horizontal lines, flickering all over the image. Is it just my camera, or is it a known problem?

    Reply
    • Hi Danny.
      The quality of the picture is low, but I didn’t get horizontal lines.
      Some readers reported that powering the ESP32 with 5V through the 5V pin can help solve that issue.

  33. What do I wrong?
    Wn10 environment
    RPI 3B
    No pblm with the installation of the ESP. It works and gives me the IP address.
    But impossible to install Home assistant.
    I’ve loaded the file “hassos_rpi2-2.12.img.gz”. Extracted it gives me he file “hassos_rpi2-2.12.img”.
    I load this file with Etcher on a (new) 64GB SD card.
    Etcher comes back with “all fine” after a few minutes.
    But the SD card is empty and asks to be formatted…
    Nothing has been copied on the SD card…
    I’ve also used “Win32DiskImager” with same results.
    Tested several times.
    Any idea?

  34. Unlike most of your projects, this one was a disaster…I have bought three ESP32-CAM boards and none of them have yet to produce an image. I have tried running them off both 3.3v and 5v and can get a wireless connection but no image is displayed. I have also tried the ESP32 WebCameraServer example and this didn’t work either (‘camera not supported’ message)

    Bit disappointed I have wasted my money but I guess perhaps the boards and cameras vary although they all advertised as the same!

    I did manage to get one board where the chip was marked ‘AI Thinker’ but this didn’t work either 🙁

    • Chris.
      The camera not supported message could be an indication that the camera ribbon cable is not connected correctly. On the ribbon cable should be a line, when connected if you can see that line, the cable is not pushed in far enough.
      I had the same problem, and fixed it with reconnecting the ribbon cable correctly.
      Please try reconnecting again and see if this fixes the problem.
      Hope this helps.

    • I had similar problems initially using just a cheap Chinese version from an eBay seller. I have found that it definitely needs to be be powered from 5v not 3.3v and you need to have a good wifi connection. If necessary, configure the antenna link and use an external antenna – dirt cheap from eBay sellers. The camera connects every time now for me with no “camera not supported” error messages and stays reliably connected. I have to say that the picture quality is very good – easily as good as other cameras that I have that were much more expensive. The second issue that I had was with the browser that I tried to use to look at the camera output. Under Windows 10, my preferred IE v10 will have none of it. Although it connects and all looks to be well, the picture window is just blank. However, both Chrome under W10 and Safari under IOS on my iPhone produce an excellent picture as soon as “Start Stream” is clicked

  36. Hi,
    I have been able to install everything. Not as easy as described…
    Now I’ve a pblm to retrieve the images taken with the OV2640 and put them in HomeAssistant.
    You write simply to add the url (http://192.168.1.91/ in your ex.) but this is no working in my case.
    If I want to get an image in HA, I’ve to use the complete url like found in the image source file of OV2640 application.
    This is what I’ve to use: “http://192.168.0.162/capture?_cb=1559298840529”
    BUT this is not working automatically. I’ve to update the address manually.
    Not the best solution.
    Do you have a idea how to improve?

      Regarding your question.
      We’ve got everything working fine by just copying the URL. So, I don’t know what can be the issue in your case.
      If you go to the IP address, outside Home Assistant, can you see the video streaming properly?

        mjpeg_url: http://192.168.1.54

  37. I got this working on a chinese no-brand ESP-CAM – works well, though lots of latency and the occasional vertical line – but running at 5v has helped somewhat.

    I think the latency is due to the sheer size of the image – 1600×1200. Is there any way to get a reduced image size from the CCD – or maybe force a slower refresh rate of 1 frame per second.

    Thanks!

    Reply
    • Solved:

      config.frame_size = FRAMESIZE_SVGA;

      This makes it 800×600. A bit better, but still a bit wobbly. I suspect there isn’t enough CPU there to handle lots of movement.

  38. Hi Sara,
    I have two questions. When I install the program and run it, everything works fine. However, if I detach it from the programmer and power it with the 5V powersupply, I cannot seem to connect to it anymore. Do you have any suggestions? Another questions is regarding Octoprint. It has a feature to use a camera stream to monitor 3D prints. I was wondering if you could use this setup as a stream in Octoprint in stead of the fixed Raspberry Pi camera?

    Cheers,
    Peter

    Reply
    • Hi Peter.
      What external power supply are you using? I’ve experimented with a phone portable charger and it worked fine.
      You can have just one client at a time, so if you have a previous tab open, when you try to connect again, it won’t show anything in the new tab. You need to close the previous tab.
      Also, make sure that when you are powering it with the external power supply, the ESP32 is within the wi-fi range of your router.
      If the octoprint software provides the option to add an ip cam, it would probably be compatible. You just need to pass the streaming URL.
      Regards,
      Sara

    • You can monitor it via FTDI while being powered by external cable.
      Just do not connect power line from ftdi to camera, leave it unconnected.
      Then connect external power supply to either 5V or 3V depending on your external power supply voltage (probably 5). And then make a common ground. Just connect gnd from ftdi to one of the ground pins, while also connecting ground from your external supply to some other gnd pins. And voila, the ftdii is able to monitor it and display the output in terminal. You can then check, what is happenning.

  40. Hi Sara

    My ESP camera worked a treat whilst I was away and provided a good security picture of my house. Couple of questions that I hope you might be able to answer. First, where is the user interface located ? Is it a piece of software built into the camera that the Arduino sketch interacts with, or is it part of one of the Arduino libraries that is used in the sketch ? Can the “Start Stream” button effectively be ‘pressed’ in software i.e. without having to click on the button so that the camera is streaming immediately from when it connects ? Also, where is the post number that it is outputting on defined ? Can it be changed from 80 so that more than one ESP 32 cam module can be active on different IP addresses. I’m sure others must want to do this as more than one camera would be really useful. These are probably dumb questions but I’m pretty new to all this and am just pleased that I have gotten as far as I have already with your tutorial and help 🙂

      Some of our readers reported that if your network credentials have more than 11 characters, it will not work.

      Also, I’ve recently discovered through one of our readers, that some ESP32-CAM boards come connected to the external antenna instead of the internal antenna. Here’s what he said that might be useful:

      “Check the jumper 0K resistor by the antenna connector is in the proper position for the antenna desired. There are 3 little white squares laid out like a “<" with the middle position being common. With board turned so the the pcb antenna up, to use the pcb antenna, the resistor must be on the top position, like this: / For the antenna connector, the resistor must be on the bottom position, like this: \ " The board provides a connector for an external antenna and has an onboard antenna as well. If your ESP32 comes with the external connector enabled, you can try adding an external antenna. Or solder/unsolder to use the internal antenna. I hope this helps. Regards, Sara

  42. Hey. Hope this might help someone. The ESP32 cam units cannot connect to a WiFi hotspot where the SSID has more than 11 characters in the name.

        If this the case, do you have a suggestion?

          Some of our readers have done that, but I don’t know how to do that. Maybe a google search can help with that.
          Some routers also provide the option to create guest networks. That can be a better alternative because you won’t have to change the systems that are already connected (if your router allows that).

Edit this just like the sketch mentioned in this post and flash it. Setup a new camera in Domoticz Settings > More Options > Cameras, give it a name, enter the IP address of the ESP32CAM, leave the Port number blank and enter ‘capture’ as the imageURL.

      • Hi Pierre. Thanks for your instructions on getting the cameras to view in Domoticz. I now have this running on a Widows 10 PC and it’s the first application that I have been able to get to see multiple instances of the ESP 32 cam board each on a different local address.

        Can I now set this up on my iPhone so that I can view the cameras remotely from anywhere in the world ? Please bear with me. I’m very new to all this !

        Reply
        • You can remotely view the cams directly by setting up port forwarding on your router, however since they have no security at all, anyone can access them, so I wouldn’t do that.

          Reply
        • In stead, I suggest you install Domoticz on a Raspberry Pi that will act as a server and can stay on permanently. This way, the camera’s are only connected to your local network, but you can access them from outside through the Domoticz server, which is protected.

          Reply
          • Hi Pierre. Thanks for your input. I have a Pi that I may well set up as you say. At the moment, the W10 machine whose network they are connected to, runs continuously and already has the router set up for forwarding. I now have two ESP32 cam boards set up and visible in a copy of Domoticz running on that Win10 machine. I have a copy of Domoticz now installed on my iPhone, and would like to be able to view the cameras on that phone, either via a 4G connection or any other wifi network that I might be connected to with the phone, for instance when I am away. However, I don’t know what I have to do to set up that remote viewing for the cameras – or any other device – on the iPhone copy. I just have a page with “HTTPS” and a port number on it, an empty field called “Directory”, “username” and “password” and a couple of other bits. Do I need to fill some parameters in here or go straight to “next”. As I said, I’m very new to all this, although very experienced in electronic service work. Thanks for your time and feel free to contact me direct if you would rather

          • You can Just open a browser window on your phone and from there, see Domoticz and the camera’s. I do that on my Android phone since the Domoticz app (which is also available for iPhone) for some unknown reason doesn’t show the camera streams at all.

          • OK. Pity that the app doesn’t work in that respect. I was rather hoping that it would. So what URL do I use in the browser to get to my data through Domoticz ? I’m starting to get a bit confused now …

          • Add a port forwarding rule in your browser in which your public ip address with a port of your choice will be forwarded to the local address of your Domoticz server. There are numerous guides about port forwarding available on the internet.

  46. Hi, I loaded the script in my newly arrived ESP32-CAM but the video fps seems to be very low.
    I started ping -t 192.168.99.100 (ip acquired by my ESP32-CAM) and the response time rums at 1000ms, 1300ms, some times 18ms, etc

    Can I make the size of the picture on screen half its current size?

    If I want to have a button to activate an external light how could I put this button at the same screen as the image?

  48. I could not program mine yet I have exactly the same FTDI as you link to.
    I looked at your trouble shooting section and one was to use 5v, so I connected the FTDI direct to the 5v line and worked fine.
    In hindsight, the FTDI supply output IS 5v not 3.3v, only the data lines (RX/TX) are switchable between 3.3v and 5v, but the supply is always 5v volts.
    This means I put 5v directly onto the ESP32 bypassing the onboard regulator which could have damaged the ESP32.
    May I suggest that you re-draw you diagram to show a connection to 5v as currently using that FTDI you are connecting 5v to a 3.3v input even though you have labeled the supply on the diagram as 3.3v, it is actually 5v.
    Hope I have saved someone from destruction.

  49. Great article.
    I see various people have trouble with the “Banggood model”
    Obviously I am not sure which model they got, but I presume it is the dirt cheap Geekcreit model (6 euro’s or something).
    I got one and didnt really have much trouble with it. It has an AI-Thinker chip on it, and that setting seems to work for me.
    If you freshly get that model, you may be in luck that it already has a working camera program in it, which is a good way to check if your model is actually working.
    What you need to do is to go to your WiFi AP list and select the camera AP (I forgot the exact name, but you will recognize it) connect to that. Subsequently go to 192.168.4.1/jpg_stream and or /jpg to get either streaming or stills.
    That way you know your camera works fine or not.
    I reflashed mine, simply because I found the built in program a bit limited, mainly because it was on its own network.
    For the reflashing many good tips are given already:
    connect GPIO0 to ground and then reset.
    Use 5 Volt Vcc (but 3V3 FTDI module).
    Make sure you operate it with a decent PSU, decent in terms of current it can supply and cleanliness of the powerlines

        Do not expect a WiFimanager on 192.168.4.1 (too bad)

  52. I found that increasing the size of part_buf to 256 bytes greatly improved the speed of JPEG streaming. Just two lines to change:

    size_t hlen = snprintf((char *)part_buf, 256, _STREAM_PART, _jpg_buf_len);
    res = httpd_resp_send_chunk(req, (const char *)part_buf, hlen);

  53. I’ve finally found an easy to use free app that connects to multiple instances of the ESP32 cam board without issue, and allows remote viewing over the internet on a smartphone. It has all sorts of useful features like zoned motion detection that I haven’t had time to investigate yet.

    netcamstudio.com/ to download the desktop part of the app.

    Add cameras using the “Custom URL” tab in the “Add Source” window. Format is

    “http://192.168.xx.xx:80/capture”

    where the address is whatever your router has assigned to each ESP32 cam board.

  55. I really appreciate all the effort you invest into these tutorials and videos. I tried this and I followed all your instructions and it worked after I selected the AI Thinker ESP 32 Cam option under the board manager. With this option you can only view the camera within your network and only one viewer at a time. Since this was not a solution what I wanted to implement, I look further into this and I found that you can easily integrate the same camera into Home Assistant using the Esp32 Cam node in EspHome. It’s much easier and now I can view my camera from anywhere and several people can access it at the same time. Thanks again for all your work.

    I’ve bought my board on Ebay and it is not labeled as an “AI-Thinker” module.

    I’m working under Linux, just because Arduino IDE compile’s “years light” faster then under Windows.

    As usual there was a some troubles:
    1) The example did not compile, because “esp_camera.h” was missing. Solution: update the “esp32 by Espressif Systems version” (under Tools, Board, Boards Manager…) from version 1.0.0 to 1.0.2.
    2) When trying to upload there was an error message saying: “a fatal error occurred: Timed out waiting for packet content”. That one was hard to solve! I just solved it changing the “Upload Speed” (under Tools menu) from 921600 to 115200 (later I tried upper speeds and could got it at 460800); the one to blame it’s, maybe, my ftdi…?

    Finally it all worked as expected!

    Two final notes:
    1) Upload problems can be solved changing the “Upload Speed”.
    2) As John wrote on July 12, changing the Board to “AI Thinker ESP32-CAM” works very well and it removes the “Upload Speed” option from the Tools menu.

  58. Thanks for the tutorial, very useful, got it working after fiddling around a bit with the FTDI and things.

    About the code, I would like to set a lower resolution, say VGA because the default 1600×1200 is too much for the camera, fps is very low and image lagging
    How can I do that?

    Regards

    • I figured it out, you have to change the FRAMESIZE_ parameter like this:
      config.frame_size = FRAMESIZE_VGA;

      Maybe it helps someone else

  59. I have non AIThinker cam module. There’s AP soft in it, under IP 192.168.4.1/jpg_stream video works, but i can’t upload other soft. Serial monitor says “rst… waiting for upload” and “Failed to connect to ESP32: Timed out waiting for packet header”. I use 3,3V, 5V, Arduino IDE, esp idf, FTDI, CH340, CP2102, Windows 7 x64, Linux mint, IO0+GND, breadboard, female conectors, RST button hold or press … nothing. Serial monitor works on settings: 115200, 40MHz, DIO.
    I read that unplugging the camera or IO2+GND could help. Someone tried? I haven’t tested yet.

  61. Hi,
    Wonderful tutorials here. I followed one to connect my ESP32 Cam with Home Assistant. Is it possible to keep camera in deep sleep mode with a switch (software) to turn it on manually on need basis within Home Assistant? Appreciate any help.

    Reply
    • Hi.
      I don’t think so.
      At least, at the moment I have no idea how to do that with a software switch. Because it needs to be awake to receive something from Home Assistant (via MQTT for example).

  64. Thanks for the great tutorial, I am looking at using my current build of MotionEyeOS on Raspberry Pi, and a cluster of 4 of these ESP32-cam’s and an old wifi router, to create a low power and dirt cheap backyard wildlife monitor. I will use the ESP32-CAM (x4) simply as wifi/IP cameras, I will probably remove the IR filters, and use some PIR’s with some IR Floodlights to illuminate the area at night. All of the ESP32-cams will connect to the router and the router will feed from the raspberry pi near the back yard. The raspberry pi will also have a Wifi dongle and connect to my home router, for accessing the MotionEyeOS. Then MotionEyeOS on the Raspberry Pi will do the motion detection, image/video storage, and can even do notifications and code executions based on the motion detection algorithm configurations in the software, no PIR’s needed for image or video recording based on motion in the video stream, and it is all accessible in one location.

    • Hello I may have been poorly expressed because I write from France with a machine translation …
      Here, I would like to power my esp32-cam with 4 batteries of 1.2v and to save power, I would like to put the esp32-cam in sleep (deep sleep) with an infrared remote control, but I can not do the .ino program to achieve this, maybe this is not possible.
      My wish :
      Watch the streaming video, then put the esp32-cam on standby when I want, and later be able to put the streaming, all with a remote control and an infrared detector.
      You can tell me if this is possible and also how to do it, please?

  67. After a fresh Arduino install (1.8.10) and loading of https://dl.espressif.com/dl/package_esp32_index.json I got this:

    error: dl_lib.h: No such file or directory

    Upon searching I found someone saying that that library had been eliminated in an recent release, and the sketch would probably compile if the include was removed.

    I commented out the include line and the sketch did compile and download and run properly, with camera streaming.

  69. I am using ESP Eye v2.1 which is very similar to this camera module and flashed the camera_web_server app that came with the examples folder from esp-who repo. The camera streamed very well. However, one issue I noticed with this streaming is that if you open the URL from multiple clients (i.e. from your computer and from your smartphone) at the same time, it only streams to one client and the other client do not display anything. When I close one client, then the other one picks up the stream. Seems like the streaming server can’t handle multiple client at once. Can you test from your end if this happens to you also. If so, is there any workaround for that?

        Yes, it only serves a client at a time.

        Streaming video is a very “heavy” task, so I’m not sure if the ESP32 is able to talk with several clients. We need to search a bit more about this.

      Yes, that should be possible, but we don’t have any tutorial about those subjects.
      Maybe you can have the ESP32-CAM in deep sleep with external wake-up – it is awakened when there’s motion: https://randomnerdtutorials.com/esp32-external-wake-up-deep-sleep/
      When it wakes up, it streams video for a determined number of seconds (use timers to defined the number of seconds) and then, goes back to sleep again. That’s just a suggestion.

  73. Hello,
    Well, I used Rui’s codes about a year ago, and they worked correctly (both web server and face recognition)
    The web server is currently working and streaming, right now.

    I’m trying to upload again, without success.

    I’ve checked everything:

    Code is clean, settings as described
    #define CAMERA_MODEL_AI_THINKER,
    Wifi credentials are ok

    On Arduino IDE:
    – Board Manager: esp32 version 1.4 installed (also tried 1.2)
    – Board set to “AI-Thinker ESP-CAM”
    – Port set to the FTDI pgmr
    – FTDI set to 5V

    Wiring:
    – FTDI 5V -> ESP-cam “5V”
    – FTDI GND -> ESP-cam “GND”
    – FTDI TXD -> ESP-cam “UnR”
    – FTDI RXD -> ESP-cam “U0T” (also tried swapping them)
    – On ESP-cam, “IO0” and “GND” connected
    – Pressed the ESP “RST” button (also tried without)

    Upload sketch from IDE gives: (hidden the mac address below)

  74. Dear Sara!
    I worry that esp32 cam has a compatibility issue with severa web browsers: My goal is not record the video, just broadcasting live picture – occassionally.

    I’ve tried to watch live stream with several browser while many couldn’t display. Hereby i enlisting:

    Google Chrome 80.0 . : Error message: Header fields are too long for server to interpret

    Microsoft Edge 20.1 .: start to download the stream to file, but not showing…

    Internet explorer 11.0 : start to download the stream to a file, but not showing…

    Firefox 72.2 : works perfectly, but i don’t dare to update, as i worry that will cause malfunctionality on show the camera stream.

    So, i think the camera HTTP header does not contain proper informations about the streaming to the webclients…

    What do you think? what browsers could you offer for live stream watch, and/or is there any bugfix available for the camera program?
    (I ve tried both of your projects, another one is directly start to streaming, and doesn’t have setting page, both are doing the same)

    Thanks for your response in advance!

  75. Hi Rui and Sara,

    when i used the code with the video stream i have an issue, the default code works great.
    But if i add #include which i want to use as a second server with on a different port, just adding this statement make the compiler go crazy, just try it yourself and you will see.

    Seem to be a compatibility issue between libraries.

    What do you think ?

      The flashlight is connected to GPIO 4.

      const int ledPin = 4;
      void setup() {
      // initialize digital pin ledPin as an output.
      pinMode(ledPin, OUTPUT);
      }
      void loop() {
      digitalWrite(ledPin, HIGH);
      delay(2000);
      digitalWrite(ledPin, LOW);
      delay(2000);

    • ESP32 dev module in the Arduino IDE
    • AI Thinker camera module in the code

    Be careful as the connection diagram showing how to connect the ESP32 to the FTDI board (near the start of this tutorial) is a bit confusing: the connections shown on the FTDI board are reversed, so be careful and read the (tiny) text on the FTDI board before connecting the boards.

  83. Thank you for some great tutorials, really enjoyed them and they have been very helpful. However I have a problem with this one. I have installed this on two different ESP32-cam cards but both suffer from the same issue. At the outset it works as expected, but after some hours (12-20 hours) the server seem to crash and become unresponsive. If I unplug power and reconnect it will work for hours again before the same happens. As mentioned behaviour is the same with two different cards. I have also tried several different power sources to rule out unstable power supply as the reason. So I am a little lost here. Any ideas?
    As a work around I was contemplating implementing an hourly reboot, but not sure how to do so through software. Any pointers?

  84. Hey guys!

    I’ve been trying to get this code running on my ESP32-CAM module for a few days and I just can’t get it to work.

    My module is an AI-Thinker (the same you have on the photos). It works fine with an ESPHOME generated code or the basic webserver demo code.

    After uploading the code provided on this page, it enters an endless reboot cycle and I can’t get anything on the serial monitor.

    Since I know this is a power-hungry module, I’ve also tried powering it with my lab power supply. Same behavior of endless reboot cycles.

    I noticed you mentioned selecting the Huge app partition profile in a previous post. On a fresh install of the Arduino IDE, these options aren’t available in the tools menu when selecting the AI Thinker board. They are when other ESP32 boards are selected.

    Just in case, I also tried to compile using the ESP32dev and wrover boards profiles (which do have the partitioning options available). Obviously, these didn’t work either.

    Just to be sure, I’ve also tried programming it with both 3v and 5v logic.

    I’m running out of things to try to make this code work on my board. Any ideas of what else I could try?

    Thanks!

        • Hi Richard,

          The endless reboot problem may be related to the Wifi portion of the project. I suggest building a sketch with the WiFi ONLY to test. See below. If you can get this working with no issues then move on to include the camera.

          //Wireless for ESP 32
          #include <WiFi.h>
          char ssid[] = “yourSSID”; // your network SSID (name)
          char pass[] = “yourpassword”; // your network password

          void setup()
          {
          Serial.begin(115200);Serial.println(); Serial.println(“Power Up”);
          Serial.print(“Connecting to “); Serial.println(ssid);
          WiFi.begin(ssid, pass);
          while (WiFi.status() != WL_CONNECTED)
          {
          delay(500);
          Serial.print(“.”);
          }
          Serial.println(“”); Serial.println(“WiFi connected”);
          Serial.println(“IP address: “);Serial.println(WiFi.localIP());
          Serial.println(“End of Setup.”);
          }

            😀

  85. Richard, Thanks for sharing your solution.
    For other users with similar issues, I suggest to re-install the “board definitions” before re-install Arduino. I experienced similar situations in the past. The “board definitions” were not “stable”. When I switched between ESP 32 and ESP 8266. In most cases, the “board definitions” need to be re-installed – very odd with Arduino 1.8.11!

    What I can’t do is get anything on my Home Assistant card when configured as you advise. This is having made sure no other clients were connected.

    • Hi.
      Yes, it can only handle one client at a time.
      That’s the most common issue – having more than one client opened.
      Without further information, it is very difficult to find out what might be wrong.

  87. Hi all!

    I’m trying to take this another step further. I’ve got it up and running fine. Now I’m trying to access it with other programs to add a little more functionality. The one connection at a time thing is killing me here. I just tried setting up an Apache server that has the IP address of the ESP32-Cam as a source. I had hoped that would allow the Apache server to be hit for multiple requests at the same time. Nope. If I have more than one window open, it only shows the cam footage on one, till I close the other.

    I suppose I could save the stream to my hard drive, then play it back with a delay through the Apache server. Less than ideal, but that would probably work.

    Ideally, I would like to have a webserver set up to show all my cameras throughout the house on one page, with options to minimize all but one to focus in on it, plus, be recording all streams to my hard drive. My other cameras seem to be okay with this, but the ESP32-cam doesn’t like the multiple connection idea.

    Thoughts?

    Hello everyone who reads and knows!)) I got stuck with this module ((((I don’t want to show the video for the life of me, I tried everything I could … I see the stream in the port monitor, even the data change is noticeable when I close the camera lens with my finger, the data goes There is no picture in the browsers. The current consumption also shows that the camera turns on, the current increases from 120mA to 200-220. The Start button in the browser does not turn on, I could turn it on only in the phone’s browser, but there is no video there either, a circle with a cross. Downloaded Tims_IP_Camera_Viewer , set the IP to the settings, the check status passes, but again there is no picture. I can’t imagine how else you can launch this miracle of narrow-eyed technology

      Does your ESP32-CAM have an external antenna?
      It may be a problem with the Wi-Fi signal. Try getting the ESP32-CAM closer to your router to check if it is related to the signal.

      • Agreed. I have six of these cameras. I don’t usually look at them directly in a browser. I normally use Netcam Studio X but I have just looked at two of them via Chrome with default settings, and by entering a direct IP address into Chrome. Both came up immediately showing the camera settings screen. As soon as I clicked “Start stream” I had a live picture. Not that it should matter at all, but I have the addresses that the router originally allocated when the cameras first logged onto my network, entered into my router’s fixed IP list so they can never change

          • In the Netcam Studio Client (Pink bird icon) running on the host computer, select the ‘Add Source’ tab. Then the ‘Custom URL’ tab from there. Ensure that ‘Stream Type’ is set to ‘JPEG’. Then enter the camera address allocated by your router in the form

            http://192.168.x.x:80/capture

            Add a Source name in the window below if you like. I leave ‘Orientation Adjustment’ as “Default” and ‘Output Resolution’ as “Native”

            Save with the ‘tick’ at the bottom, and the camera should appear in the Client Home page that you first came from. You can then set up Netcam Studio on your phone to view cameras both locally via wifi or via your external IP address from anywhere in the world. The server software (ble bird icon) on the host machine can be set to be an automatic start up utility via Windows settings / services. Set to ‘start automatically after delay’

            Hope that helps. There are tutorials online and Hendrick who wrote it is very helpful on the forum

  97. I’m having some interesting problems when I wire my ESP32-CAM to a USB cable for power. I used an FTDI Programmer to connect the ESP32-CAM to my desktop computer and successfully programmed it. Then, I stripped an old mouse USB cable and connected dupont connectors to the red and black (tested 5V on my multimeter), I also have a flashing red LED connected to D12 and GND (via a 330ohm resistor) on the ESP32-CAM.
    When connected the cable to 5V and GND on the ESP32-CAM and through a USB adaptor to power, the LED flashes as expected, but when I attempt to connect to the URL, I get an error indicating that the web server hasn’t started.

    I’ve tried connecting directly to the desktop, via a powered USB hub and the 5V adaptor, all with the same result.

    If I connect the ESP32-CAM to the 5V adaptor via the FTDI Programmer, it works … what would the FTDI Programmer be providing?

    Reply
    • Hi.
      It should work without an FTDI programmer as long as you are providing power properly.
      Make sure you press the on-board RESET button after powering the board so that it starts running the code.

  99. How do I change the streaming resolution to CIF size. I am trying to add quite a few of these on the same network. Decreasing the streaming size could help me decrease the bandwidth used by each.
    I changed,

    config.frame_size = FRAMESIZE_UXGA;
    config.jpeg_quality = 10;
    config.fb_count = 2;

    to

    config.frame_size = FRAMESIZE_CIF;
    config.jpeg_quality = 10;
    config.fb_count = 2;

    but the stream goes blank after that. What should I do?

    Reply
    • I bought another module and tried different frame sizes, namely, VGA, QVGA, SVGA and they worked just fine. With size set to CIF it was still not working though. I settled for VGA in the end. The framerate is much better on lower resolution aswell. Maybe this info could help someone in the future. I still haven’t figured how I could password protect the stream though.

  101. Hi, I am able to view the stream when my system/mobile is on the same router as the camera, however, I am unable to access the stream when my system/mobile is connected to a different router on the same network(both routers are connected via a switch). Can you help me out? I am not very good with networking.

    Reply
    • Devarshi – What hat you are trying to do probably won’t work because the router the camera is attached to is blocking the inbound request to get to the ESP32. Routers generally block unsolicited inbound requests. The network has (likely) been divided up for security reasons. You will need to talk to whoever manages the network to find out.
      If that is the case. In principle this can be fixed by opening a port in the router and pointing it to the ESP32, but whoever owns the network might be very reluctant to do that.

      Reply
      • Hi David, thanks for the reply. I had my doubts that it had to do something with the router. I am setting up multiple such cameras throughout my home and shop over many different routers which are connected through a switch.
        Let me explain what I am trying to do. I managed to reduce the resolution of the stream to VGA size so that the cameras don’t take too much bandwidth on the routers and don’t slow down the internet or NAS.I even got a case 3D printed for a prototype and and wrote basic Django server to serve each stream on a single page and save motion parts locally on the NAS. I plan to deploy this on a Raspberry Pi.
        Sounds like I’ll have to rummage around TP-Link documentations for port forwording/opening. I might have to password protect the stream though – Do you know how that can be done?

        Reply
        • My experience with ESP32 is strictly experimental! I run a network of cameras but they are a mix of old Wi-Fi ip cameras and Pi Zeros. From what work I have done with the ESP32 it seemed, to me, to be much harder to make work and less reliable than the Pi zeros. I use Motioneye as the hub on a Pi4b. So far I’ve failed to make and ESP32 connect to it reliably whereas my Pi Zeros do so immediately. However, all a matter of personal preference and available skills!

          As far as the routers go……..

          I only have the one between me and the internet so the situation is very different. All my cameras are on the same network. My arrangements for access from outside my networks are quite different.

          But, by default all routers block unsolicited inbound traffic. If you have multiple cameras behind a router you either have to open one port per camera (because a port can only be routed to one IP address). So, you will have to do that for each router that has a camera or cameras behind it! You would open, say, ports 3380, 3381,3382 pointing each at port 80 on the IP address of each ESP32. Or, it might be port 81, because the ESP32 I have streams just the video on that port. You need to find out!

          Can I ask why you have multiple routers if it is all one network?

          Password protecting the stream would need to be done on the ESP32, in effect password protecting access to the web server that sends it. No idea how that is done! Another reason I used the Pi – the software I use comes with that feature built in.

          Reply
          • Sorry for the late reply.
            My house is big one router’s reach wasn’t enough. So I have multiple routers. I figured I might have to do some tweaks on the ESP32 for password protecting the stream. I wasn’t able to figure out the port forwarding thing. From what it appears, I will need to open ports at the router aswell as the switch. Will probably ask help from someone who is good with networking.
            My main motivation for using ESP32 cam was it’s price. Since I am going to add 10 such cameras on the whole network. Otherwise I would probably have gone with RPi Zero W aswell. ESP32 cam is smaller aswell, so it will probaly be cheaper to 3D print a case for it.

            I will use a RPI 4 a server for assimilating all streams on a page. All in all, it was a wholesome project overall.

  102. I have found that not only will this not serve more than one stream, but the server will not respond to another simple http request such as something that gives a 404 result. It’s as if the whole http server is locked up serving the video. Does anyone have an idea on what is causing this and/or a way to fix it? I need to serve some simple pages while the video is streaming.

    Reply
  103. I understand this now and have fixed it. Any one server can only serve one http request at a time. Since the stream request never ends that server can’t process anything else. My solution was to simply create a new server. The stream is on port 8080 and the normal page server is on 80. If anyone wants to see the code let me know.

  104. Hi,
    First of all, thanks for this project and all the other projects on your site! Really awesome!

    I just purchased a ESP32-CAM with integrated CH340 and mini-USB port from Aliexpress (advertised as HK-ESP32-CAM; mind the omission of the trailing ‘MB’). It makes this board look very much like a regular ESP32 DevKit; you can flash and power the board using the USB port. At first I couldn’t flash the software, though, but the comments here helped a lot! Hence me sharing my experiences; maybe it helps someone.

    This board – it works fine if you use it as ‘AI-Thinker’ module in Arduino IDE – has two buttons next to the mini-USB port. On the left it says RST (Reset) and on the right it says ‘FLASH’.
    Now, when you’re ready to upload the Sketch, you click the ‘Upload’ button in the IDE and then press AND hold the FLASH button (right button). Then, when the IDE shows the connection dots (‘….____….____ etc.) you press RST once while you keep holding the FLASH button until everything is uploaded. When the IDE says it’s done, release the FLASH button, press RST once again to make sure and check you code runs.

    void setup()
    ….
    esp_task_wdt_init(WDT_TIMEOUT, true);
    esp_task_wdt_add(NULL);

    void loop()
    ….
    esp_task_wdt_reset();// at the start reset the watchdog and then later e.g. in if(!fb)

    This restarts the ESP32 whenever it hangs automatically after 30 secs (WDT_TIMEOUT)

  121. I filed a bug report against the main code as the camwebserver is one of the examples. I was told that face detection has been removed from the library. So is there a workaround? The esp32 board does work with other code such as WiFi antenna check and cpu I’d. Thanks.

  123. Hello Sara,

    Thanks a lot, this is an awesome article.

    I followed the steps and managed to stream OK to my ip. However, I can’t capture the stream on OpenCV. This is my python code:

    capture = cv2.VideoCapture(‘http://MY_IP’)

    I get an error: OpenCV: Couldn’t read video stream from file “http://192.168.1.21”

    I am really running out of ideas, some help would be much appreciated. I have tried the article about OpenCV and others but I can’t make this thing work

  124. hello Sara,
    I must be missing this file as I get compile error
    pp_httpd.cpp:22:10: fatal error: fd_forward.h: No such file or directory
    #include “fd_forward.h”
    ^~~~~~~~~~~~~~
    compilation terminated.

    Should it be part of a standard package for esp32? If not where should I find it?
    I got the cam sketch by downloading and extracting the zip file.

    I am using the esp32-cam board.

    tks don

    • Hi.
      There should be no need to install that.
      Make sure you have the ESP32 boards installed in your Arduino IDE and that you have selected an ESP32 board in Tools > Board.

  125. Am I right that if I want another resolution I change line 231 (and 235)?
    I want to mount a camera in the front of a modeltrain locomotive to be able to see what the driver of that loc would have seen.
    I don’t want a very high resolution as I want a nice framerate.

  127. Hi Sara,

    I flashed your code to a ESP32-Cam module and it’s working fine. The only issue I have is that I can only access the webserver from one device at a time. If I connected with my mobile phone and try to connect from my computer it doesn’t work. What have I to change to get access from multiple devices?

    Reply
    • I never found a solution to this, so eventually, I downloaded a free copy of Netcam Studio. You can connect as many ESP32 cameras as you like, but only two are un-watermarked n the free version. You can connect a phone and a PC at the same time to any camera on your local network, and you also have the ability to connect from anywhere in the world via your external IP address. There is an app to go on your phone to facilitate this. There is also a local client to run on your PC so you don’t have to go via a browser. The app also has sophisticated recording features with automatic archiving by date and time. I have no affilliation to the producers of this software. I hope you find this useful

  132. Hi, I love the simplicity of this bit of code, I wanted the simplest possible way to add a wireless camera to my ad-hoc group of IP cameras, and it works great with my Security-Eye setup. The only thing I wish it had was a time/date stamp overlay, or even a blinking dot overlay on the stream so I can know if the camera is still alive remotely. Is there any way to do that?

  133. Hi Sara,
    I was wondering if it is possible to use the ESPAsyncWebServer for the stream?
    Then possibly running AsyncElegantOTA for OTA updates?

  134. I want to stream videos using the example code “CameraWebServer” outside my local network. I’m able to set up port forwarding on my Netgear N600 router for accessing the ESP32-CAM web page from anywhere (Port 80). However, only the “Get Still” function works. The “Start Stream” button yields a broken image icon. I read somewhere that Port 81 is for streaming. But how do I set it up so that it works for displaying the web page (Port 80) as well as streaming (Port 81)?

  137. howdy!

    I have 2 of these ESP32-CAMs and oddly, 1 will works well only when connected to the computer’s USB. When I use external power, the refresh rate is super slow.
    Strangely, the other unit works perfect on external power. I can’t figure out why that would be. I did turn off the debug flag, but no effect.

    thanks for any info you might have.

  138. Hi,
    your code was the only way to bring my ESP32-Cam to live – thanks for that! The “original” Arduino-IDE-example didn`t work, I tried a lot of settings but no way. With your sketch one try: success!
    What I’m missing: is there a possibility to set some sliders in a settings-menu to adapt “brightness”, “saturation”, etc.?

    thanks again,
    kind regards,

    As always your tutorials are great and my issue is not with your tutorial but my own hardware.
    The video and stills taken by my esp32-cam are out of focus, is there anything I can do on a software side to get them back in focus or do I just have a bad cam?

      Bad focus? I’m not sure… It’s probably a problem with the camera?
      Did you remove the small plastic that protects the camera when you first get it?

  142. Hi,
    Can you make a tutorial of how to send images using MQTT to a Home Assistant installation? My goal is to get one single image from a remote ESP32 camera by request (flipping a switch on HA).
    The setup would be:
    – a HA installation on site A
    – an ESP32-cam on site B, connected to Mosquitto broker on HA via Internet
    – HA would post a request on a dedicated topic and so the ESP32 will send back a base64 encoded image on some topic so HA would display it.
    That would be the plan but it overwhelms me for the moment 😐
    Thank you!

  143. Hi,
    After my issue with my last cam that was out of focus I got another cam, this time the picture is perfectly clear which is great, but this time the video streaming and photos are rotated 90 degrees. I see in another of your tutorials you explain how to rotate photos by 90 degrees but I am not seeing anything about rotating video stream, is there a simple solution or should I redesign the box I created to hold the cam?
    Thanks

    • I think you will find that it is a function of the actual mini camera, and not something that can be changed. I am sure that this has come up on here before. I have used a lot of these cameras, and I have had a couple where the image is rotated by 90 degress

  145. Hi
    I would like to be able to use this project to observe a location on demand but using battery power. Making the camera work on a lipo is not a problem but the current draw is! What is needed is a way to have the camera sleep (doesn’t have to be deep sleep, modem sleep or light sleep would work) and wake up when my browser sends a request, The go back to sleep when the browser closes the page. This would be an invaluable device which would allow you to monitor any location on your property when you want and where wifi could reach. Any chance this might be a future project ?? Thanks for all your good work!

  148. Hi, I have installed the standard example with ESP32CAM.
    when I access it inside my local network, it works fine, I can start and stop the streaming, save pictures, even command the LED brightness etc.
    Then I built a redirection to be able to reach it from outside.
    I redirected to port 80.
    When I call this address (http of course, not https) it shows the usual command screen but there is no image shown during the streaming, and moving the LED brightness slider does not make any difference.
    I tried it from a computer, then from a mobile phone and both devices provide the same result.
    Do I need to open another port?
    Or is there something different to look at?
    Thanks

    • For local home coverage, the ESP-32 is tied to you local modem, so anybody with password access to your local network can access it.

  150. Hi Sara,
    I tried your code with a AI Thinker ESP32-CAM and it works nicely. Is there a possibility to modify the camera settings after initializing the camera module from within the sketch? I would like to flip the screen vertically. I tried to do so by fumbling around with those parameters in sensor.h but wasn´t successful.
    Keep up the good work!
    Regards
    Albert

    Reply
  151. Hello Sara,
    I have to apologize for molesting you. I figured it out by myself how to flip the screen.
    After initializing the camera I added:
    sensor_t * s =esp_camera_sensor_get();
    s->set_vflip(s, 1);
    That was all. I assume it works for other camera parameters defined in sensor.h as well.
    Keep up the good work!
    Regards

  152. Worked instantly, thanks.

    I do have a small issue. I am using my laptop browser to view the stream. It works for maybe a minute or a little longer, then the browser window freezes. I can restart it just by clicking the restart (circular arrow icon). I suspect this is a wifi connection issue due to low power on the ESP32-cam unit, but have no way to verify. I do not have to restart the ESP32-cam unit. Any ideas how to keep this stream going?

  153. Hello Sara,
    I have two ESP32-CAM. One is Ai-thinker and I have it working now, quite difficult at beginning.
    The second is a Wroom and it seems to work, but I get a big frame named “Toggle OV2640 sttings” which gives opportunity to adjust all parameters. It covers the complete screen and I can have the stream from the camera by clicking “Start Stream”, and that is really a very small picture and the table doesn’t disappear.
    How can I remove this frame ? I can disable it by clicking just on the left corner, but it comes again each time I want to use the camera.

    Reply
    • I have downloaded again the script, the same script and it works fine now. This unwanted frame is not there anymore.
      I cannot understand where it came from, but it works anyway.

  154. Hello,
    I have loaded the ESP32CAM Webserver, and it works, but I have the configuration menu always active. I mean I have on top of the screen (on my android) a menu called “Toggle OV2640 sttings” and I really don’t need this menu.
    Of course, I can hide the menu by clicking on it, but it appears each time I connect and I wish to have something working without any human act.
    How van I remove this feature ? I guess it is somewhere in the PSRAM, but I cannot delete it and I am afraid to break the ESPCAM if deleting it without adding a link to my script.

    Reply
  155. Hello and sorry for the inconvenience.
    I studied a bit the examples related to the ESP32CAM with the two libraries:
    ESPAsyncWebServer and esp_http_server.h.
    I would need to perform video streaming and manage a button capable of capturing the single image. Is it possible to have an example that replicates this function with the second library or alternatively to have some links about it?
    I searched a lot but didn’t find anything easily applicable.
    Thank you.

    • I run a free program called Netcam Studio, which allows two completely free cameras, and as many more as you like, but with a translucent banner across their pictures. You can remove this by purchasing a license for a very reasonable price. There is an app to run on your phone which allows you to connect to your cameras by wifi if you are on the same network, or from outside via the internet talking direct to your external IP address. Works very well. I have six ESP32 cameras connected
