You can use the preceding links or go directly to MakerAdvisor.com/tools to find all the parts for your projects at the best price!

Introducing the ESP32-CAM

The ESP32-CAM is a very small camera module with the ESP32-S chip that costs approximately $10. Besides the OV2640 camera, and several GPIOs to connect peripherals, it also features a microSD card slot that can be useful to store images taken with the camera or to store files to serve to clients.

The ESP32-CAM doesn’t come with a USB connector, so you need an FTDI programmer to upload code through the U0R and U0T pins (serial pins).

Features

Here is a list with the ESP32-CAM features:

  • The smallest 802.11b/g/n Wi-Fi BT SoC module
  • Low power 32-bit CPU,can also serve the application processor
  • Up to 160MHz clock speed, summary computing power up to 600 DMIPS
  • Built-in 520 KB SRAM, external 4MPSRAM
  • Supports UART/SPI/I2C/PWM/ADC/DAC
  • Support OV2640 and OV7670 cameras, built-in flash lamp
  • Support image WiFI upload
  • Support TF card
  • Supports multiple sleep modes
  • Embedded Lwip and FreeRTOS
  • Supports STA/AP/STA+AP operation mode
  • Support Smart Config/AirKiss technology
  • Support for serial port local and remote firmware upgrades (FOTA)

ESP32-CAM Pinout

The following figure shows the ESP32-CAM pinout (AI-Thinker module).

There are three GND pins and two pins for power: either 3.3V or 5V.

GPIO 1 and GPIO 3 are the serial pins. You need these pins to upload code to your board. Additionally, GPIO 0 also plays an important role, since it determines whether the ESP32 is in flashing mode or not. When GPIO 0 is connected to GND, the ESP32 is in flashing mode.

The following pins are internally connected to the microSD card reader:

  • GPIO 14: CLK
  • GPIO 15: CMD
  • GPIO 2: Data 0
  • GPIO 4: Data 1 (also connected to the on-board LED)
  • GPIO 12: Data 2
  • GPIO 13: Data 3

Video Streaming Server

Follow the next steps to build a video streaming web server with the ESP32-CAM that you can access on your local network.

Important: Make sure you have your Arduino IDE updated as well as the latest version of the ESP32 add-on.

1. Install the ESP32 add-on

In this example, we use Arduino IDE to program the ESP32-CAM board. So, you need to have Arduino IDE installed as well as the ESP32 add-on. Follow one of the next tutorials to install the ESP32 add-on, if you haven’t already:

2. CameraWebServer Example Code

In your Arduino IDE, go to File > Examples > ESP32 > Camera and open the CameraWebServer example.

The following code should load.

ESP32 CameraWebServer Example

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.

So, comment all the other models and uncomment this one:

// Select camera model
//#define CAMERA_MODEL_WROVER_KIT
//#define CAMERA_MODEL_ESP_EYE
//#define CAMERA_MODEL_M5STACK_PSRAM
//#define CAMERA_MODEL_M5STACK_WIDE
#define CAMERA_MODEL_AI_THINKER

If none of these correspond to the camera you’re using, you need to add the pin assignment for your specific board in the camera_pins.h tab.

Now, the code is ready to be uploaded to your ESP32.

3. ESP32-CAM Upload Code

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

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.

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.

Accessing the Video Streaming Server

Now, you can access your camera streaming server on your local network. Open a browser and type the ESP32-CAM IP address. Press the Start Streaming button to start video streaming.

You also have the option to take photos by clicking the Get Still button. Unfortunately, this example doesn’t save the photos, but you can modify it to use the on board microSD Card to store the captured photos.

There are also several camera settings that you can play with to adjust the image settings.

Finally, you can do face recognition and detection.

First, you need to enroll a new face. It will make several attempts to save the face. After enrolling a new user, it should detect the face later on (subject 0).

And that’s it. Now you have your video streaming web server up and running with face detection and recognition with the example from the library.

Troubleshooting

If you’re getting any of the following errors, read our ESP32-CAM Troubleshooting Guide: Most Common Problems Fixed

  • Failed to connect to ESP32: Timed out waiting for packet header
  • Camera init failed with error 0x20001 or similar
  • Brownout detector or Guru meditation error
  • Sketch too big error – Wrong partition scheme selected
  • Board at COMX is not available – COM Port Not Selected
  • Psram error: GPIO isr service is not installed
  • Weak Wi-Fi Signal
  • No IP Address in Arduino IDE Serial Monitor
  • Can’t open web server
  • The image lags/shows lots of latency

Wrapping Up

The ESP32-CAM provides an inexpensive way to build more advanced home automation projects that feature video, taking photos, and face recognition.

In this tutorial we’ve tested the CameraWebServer example to test the camera functionalities. Now, the idea is to modify the example or write a completely new code to build other projects. For example, take photos and save them to the microSD card when motion is detected, integrate video streaming in your home automation platform (like Node-RED or Home Assistant), and much more.

We hope you’ve find this tutorial useful. If you don’t have an ESP32-CAM yet, you can grab it here.

    • Hi James.
      Did you select the right camera module in the code?
      Please double check that your camera is well connected to the board.
      I also found this issue: github.com/espressif/esp32-camera/issues/5
      It seems the same as yours, so it might help.

  4. Hi. Great tutorial; worked like a charm once used a separate 5V supply.

    Any way you know of to see the video stream or stills via a TFT display on another ESP through web browser or otherwise? I’ve used ESPNow between ESP12’s or 32’s for display of thermal cam images but they’re much smaller. Avoids need for phone or laptop tied up….

  5. Hi, thanks for the tutorial, but I’m getting 2 problems with the code :

    1. I can’t include the zip file through “Add .ZIP library” from Arduino IDE

    2. When I put it manually through extracting the zip file and moved it to my Arduino libraries folder, then compile the code, I got “no headers files (.h) found” error

    Any help would be appreciated, thanks again for the tutorial.

    Reply
    • Hi Mario.
      You don’t need to install any library. You just need to have the ESP32 add-on installed.
      The zip file that we provide contains all the code that you need.
      You just need to unzip the file, open the CameraWebServer folder and open the CameraWebServer.ino.
      Your arduino IDE should open the code and you’ll see three tabs at the top. Then, you just need to upload the code to your board.
      Alternatively, if you have the latest updated ESP32 add-on, you should have the code in your examples. Go to File > Examples > ESP32 > Camera and open the CameraWebServer example.
      I hope this helps.

      Sara

  6. I was looking for something like this for my recent project, Thanks! Great tutorial! But I think ESP32-CAM is “unofficial” combination of ESP32 with a camera. I think Espressif themselves released a dedicated “official” ESP32+camera board called ESP-EYE with their own “official” software library called ESP-WHO.

    Well I got all the information from here: https://www.ebay.com/itm/254177708782

    Have not tried that board myself. Can you make a tutorial on that as well since that is the “official” hardware and software and would have longer support from Espressif itself.

    Also a comparison between the 2 would be great too.

    I follow a lot of Random Nerd Tutorials. You guys make easy to follow guides. Cheers! Keep it up!

    Thanks!

    • Hi Ryan.
      Thank you for your nice words.
      The ESP-EYE is an Espressif release.
      We haven’t fully tested the ESP-EYE yet. We’ve played with the example firmware that they provide and we made a blog post about it that you can read here: https://makeradvisor.com/esp-eye-new-esp32-based-board/
      At the moment, we don’t have any more tutorials with the ESP-EYE.

  9. Hi Rui & Sarah,
    How do you set up face recognition ?

    Reply
    • It seems that face recognition is no longer working (at least with the example program) when using the 1.02 ESP core.
      Rolling back to the 1.01 core and using the example program belonging to that core, will ‘fix’ it (currently that is the program that Sara and Rui have on their Github

    • There is a small red led (GPIO33 inverted) . The main led is controlled by GPIO4. In the example CamWebServer program there is AFAIK no possibility in the webserver to switch the main LED.
      Should be possible though to program Switching the LED and control it via say HASSio or OpenHab, with an MQTT command or something. If there are any unused pins, you could add a switch

  12. I am having problems getting errors: camera_probe(): Detected camera not supported.
    esp_camera_init(): Camera probe failed with error 0x20003.

    That occurs selecting AI Thinker. The other two options give me the 0x20001 error. I bought the esp camera from DIYMORE.CC. The description in their ad prints AI Thinker on the chip, but my actual device does not have AI Thinker printed. It just has DM-ESP32-S.

    • Hi.
      Face recognition is a bit slow, however we managed to make it work fine.
      Please make sure that you have proper lighting to make the face recognition process easier and more efficient. Also, when enrolling a new face, you need to be steady and don’t move much, so that it properly saves your face features and can recognize it in the future.

  14. Hi,
    Got my hardware last week from banggood. It had the issue “Brownout detector was triggered”. Seaching the web i found this video where they say to feed by 5v not 3.3v.
    https://www.youtube.com/watch?v=tzmcXZ-irIc ~2:30
    This solved the brownout issue for me.
    Then the web service did not appear in google chrome browser. Error message was something about too much header lines or so. In MS Edge it was ok. But i have no image from the cam. Cam must be broken. So i have to wait another month to get this as spare part. Have also ordered another ESP board with an external antenna hoping to get better connection to the router.

    • Hi Patrick.
      I’m sorry you’re getting trouble using your ESP32-CAM.
      The brownout detector error usually means that the ESP32 is not being powered properly. You can read more about this on our troubleshooting guide, bullet 8: https://randomnerdtutorials.com/esp32-troubleshooting-guide/
      Our camera worked flawlessly following the steps we describe in our tutorial.
      The ESP32-CAM should work fine being powered either with 3.3V through the 3.3V pin or 5V through the 5V pin. You’re probably not providing enough current.
      Also, we didn’t have any trouble accessing the web server on Google Chrome.
      After you get a new camera, let us know how it went.
      Regards,
      Sara

  15. Any ideas what would cause a 20003 error? I have tried all three camera types. The AI Thinker gives 20003. The other two cause a 20001 error

    Reply
    • Hi John.
      I’m sorry you’re having that issue.
      Those errors usually mean that the camera is not properly connected. So, or your camera module is faulty or it is not properly connected.
      If these are not the reasons, it is very difficult for us to understand what is going on.
      Can you try using a new camera probe?

    • Hi.
      It seems that your code was uploaded successfully.
      Make sure you open the serial monitor at a baud rate of 115200, so that you can see the text on the serial monitor.
      After uploading the code, you should disconnect GPIO from GND. Open the Serial monitor, and then press the ESP on-board reset button.
      Please make sure you’ve inserted the right network credentials.
      Can you access the web server when you insert the IP address on your browser?

    • Hello Kurt, here’s what the error: “Brownout detector was triggered” means:

      When you open your Arduino IDE Serial monitor and the error message “Brownout detector was triggered” is constantly being printed over and over again. It means that there’s some sort of hardware problem.

      It’s often related to one of the following issues:

      – Poor quality USB cable;
      – USB cable is too long;
      – Board with some defect (bad solder joints);
      – Bad computer USB port;
      – Or not enough power provided by the computer USB port.

      Solution: try a different shorter USB cable (with data wires), try a different computer USB port or use a USB hub with an external power supply.

      Reply
      • Rui, I am using a USB CH340 and also a USB FTDI serial boards that connect directly to a Computer USB port, there are no cables, other than the Jumper wires. I have tried this on 3 different computers and about 3 to 4 USB ports on each one. I have also tested 2 CAM boards with the exact same results.

        The Brownout is the only thing listed on my previous post, there’s also the:

        “Guru Meditation Error: Core 0 panic’ed (StoreProhibited). Exception was unhandled. {Note that are about 60 of these in my Log}”
        Which spawn 60 TO 100 Messages before it Reboots.

          • When I powered either one of them with 5V through the USB Serial dongle the LED on the ESP board lights up and stays on, while the Serial monitor shows nothing.

  25. HI all,
    I purchased a ESP32-Cam. I have had a lot of problems trying to get it to work.
    I could nbot get the sketch to upload and a couple of other small issues.
    What I found was (
    Its all to do with the voltages…..
    and the pin configuration is different on my usb-TTl compared to the pics on the web. ) –
    1. Set the usb-TTl to 3.3V.
    2. connect it to the ESP32-CAM as shown in all the diagrams, (but put the 3.3V from the usb-Tl to 3.3V on the ESP32-CAM.)
    3. Strap the Io0 and gnd.
    .. make sure the pins you have cables on are correct… very important.
    4. Power up and upload the sketch.
    Now to test the ESP32-CAM.
    1. Remove the IO0 and gnd jumper.
    2. Change the usb-TTl to 5v (changing the pin)
    3. Change the voltage on the ESP32-CAM to 5V pin.
    4. Power up.
    5. Open up the serial monitor.
    6. Press the reset button on the ESP32-CAM.
    7. get the IP address.

    Enter the IP address in your browser. Go to the bottom to Start streaming data.
    And It works like a charm.

    If I do not change the voltage on the pins (3.3v for uploading sketch and %v for operating then I could not get anything to work.

    I hope this helps other people who are having Issues.

  26. Wonderful tutorial, quick set up….I have 1 little issue…Stills OK, Steaming NOT OK…. Everything seems to work well and good but when I press Start Steam, nothing streams. I can tell through the Monitor, and TTL connection that the Steaming mode is going, and when I stop the monitoring shifts down to lower FPS. Still captures work just fine. Am I missing something? Do I need an SD card installed to allow streaming? Arduino 1.8.9, ESP32 Espressif v1.0.2

    Reply
    • Hi.
      You don’t need SD card to see the streaming.
      I don’t known what can be the problem. Please note that you can only see the streaming on one client at a time. So, make sure that you don’t have any other browser tab making requests to the streaming URL.
      I’m sorry that I can’t help much.

    • Hi Arturo.
      Next time, post your questions in english so that everyone can understand.
      Which camera board are you using?

      Reply
        • Hi ARturo.
          That error you were referring to usually means that the camera is not properly connected or the ESP32 is not able to recognize the camera. That can be due to the following issues:

          – Camera not connected properly: the camera has a tiny connector and you must ensure it’s connected in the the right away and with a secure fit, otherwise it will fail to establish a connection

          – Not enough power through USB source: Some ESP32-CAM boards required 5V power supply to work properly. We’ve tested all our examples with 3.3V and they worked fine. However, some of our readers reported that this issue was fixed when they power the ESP32-CAM with 5V.

          – Faulty FTDI programmer: Some readers also reported this problem was solved by replacing their actual FTDI programmer with this one: https://makeradvisor.com/tools/ftdi-programmer-board/

          – The camera/connector is broken: If you get this error, it might also mean that your camera or the camera ribbon is broken. If that is the case, you may get a new OV2640 camera probe.

          Also, sometimes, unplugging and plugging the FTDI programmer multiple times or restart the board multiple times, might solve the issue.

          I hope this helps.

  30. Hi I did everything as explained and if I get ip and I can enter and start the camera but when selecting the face dectector does not work does not happen nothing does not detect the faces, I have remained still to see if it detects the face and does not work , esp32 I have it connected to the 5v pin because when I tried it with 3.3v I did not want to load the code

    • I had the same problem and the camera needs to be in good lighting conditions to get it to do any of the recognition functions…….

      Reply
  31. hello I did everything as established, I charge the code and it gives me the ip and the entry in my browser and if it enters the platform of the camera and I can start the camera only that when selecting for the face detector it does not work I have been still to see if it detects but nothing appears, and if you notice that the quality of the camera is somewhat low and I do not know if that could be the cause, there is no way to turn on the led that includes the esp32 cam to work as flash

    • Hi Jesus.
      What is the camera module that you’re using?
      If the camera board doens’t have PSRAM, it won’t be able to do face recognition and detection.

  32. Hello! Excellent tutorial, got me started real easy with the ESP32-Cam. I did got a bit stuck though:

    – First time I uploaded the CameraWebServer sample sketch, the upload process worked fine, though I could not see any traces back in the serial, even removing the GPIO 0 to GND jumper and resetting.

    – Then I tried to upload *again* and got only an error back:

    esptool.py v2.6
    Serial port COM5
    Connecting…….._____….._____….._____….._____….._____….._____….._____

    A fatal error occurred: Failed to connect to ESP32: Timed out waiting for
    packet header
    A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

    – Since I had a second ESP32-CAM, I repeated the steps above, and the results were the same: first upload from the IDE succeeded, the next one failed with the error above.

    – I did try to change the upload speed to 115200 bps, but it did not change the results

    – I did not (yet) try pressing the ‘reset’ button in the board, because it is in the back side and I have the module in a protoboard. Since the first upload worked without pressing reset, I’m not sure I need to do it this time, but I’m open for suggestions 🙂

    Thoughts?

    Reply
    • *Update*: it was indeed the ‘reset’ button underneath; if anyone is facing the same problem, just remember to briefly hit the reset button as you’re about to upload the compiled firmware.

      Everything is working fine here now, thanks again for this nice tutorial.

    • Hi Mirko.
      That usually happens when people forget to insert their network credentials or don’t insert the credentials properly.
      Please make sure that you’ve inserted your network credentials and double-check that they’re correct.
      Also, make sure that the ESP is relatively close to your router so that it is able to catch Wi-Fi signal.
      Some readers reported that powering the ESP32-CAM board with 5V solved the problem.

      Regards,
      Sara

      Reply
      • Thank you. That solved the problem.
        I was always thinking the ESP32 is opening up a own WiFi hotspot and so inserted credentials for that.
        I did not realize that it wants to connect to my Wifi and needs that credentials.
        I did not even think about that, because I thought that the ……. is a part of the camera initialisation 😉

        So again, thanx for the hint.

  36. It is also worth to say, that powering the Unit just from the Serial Converter leads to problems (at me) because the Module needs more/quicker Power than my Serial-Converter Module is able to deliver as you can see sometimes on the Serial-Monitor if there is “Brownout Detection …..”

    I just power it from any other “good” Source to work against the “inrush current” that the Module aparently needs to kick in with WiFi.

  45. Hi Guys !
    Thanks very much for this tutorial !!, pretty straight forward and concise.
    I’ve got my cameras from Aliexpress, they look very much alike to AI’s one. DM instead of AI is the brand that appears on the rfshield.
    I’ve got a Raspberry Pi to serve as a WiFi HotSpot, assign the same IP to the ESP’s MAC address and from my mobile accessing the streaming.
    A bonus: Checking the schematics, I saw that it operates with 3.3v, so the 5v go to a LM1117-3.3v voltage regulator, and this 3.3v regulator is rated up to 15V input !!!. Long story short, I’ve cramped 4 AAA batteries (6v) and the ESP32-CAM inside a GoPro-like waterproof enclosure and VOILA !!!.. .it worked… 🙂 Underwater. at least surrounded by 3 ft of water :-). I had to lower the res down to 320×240 to keep the 23fps but still 🙂
    Guys, you’re awesome !.
    thanks again
    Gabriel

    Reply
    • it is my understanding that face recognition does not work in the 1.02 core of the ESP32. It does work in the 1.01 core.
      If you revert back to the 1.01 core, make sure you also use the Camera example that comes with that core

  53. Hi Sara Santos. In a comment from may you mention that you have tried taking photos and saving them to the SD card, but failed. I managed to do this. Do you want me to dig out the code and show it to you?
    I also managed to take photos when an “intruder” is detected from a sensor. The only problem with that is that I did not manage to connect the sensor directly to the camera module. I had to use an auxiliary Arduino board with the sensor, and make it then send a command to the ESP32 module to make it take a picture. I am pretty sure there are much better ways of doing this, ideally without needing an arduino board.

  54. Hi all.
    On a DIYMore Esp32-cam all I get from Arduino is
    board esp32 (platform esp32 package esp32) is unknown
    I installed the Esp32 addon, and tryed all the Esp32 boards on Arduino with the same result.
    I am missing something, I am sure..

    Thanks!!!!

  55. Hi All,
    Nice Tutorial !!! Have not seen this issue posted anywhere. So here Goes:
    Followed tutorial, all worked perfectly until ESP32-Cam was removed from power. Then it acted like it had never been Flashed when power was restored. Even tried RST button, nothing shows up in the Serial Monitor. Can set back up to Flash and all goes well (all works) until power is removed then restored, again acts like it had never been Flashed. Bought 2 of these and both act the exact same way. Any help would be great. Thank You in Advance !!!

  56. Hi Sara

    I connect esp32 cam with Lora but it cann’t be initiatized.
    It seems that deinit(); of the esp32_cam doesn’t work as commented in esp32_camera.h. Please kindly suggest how to coexist cam and lora on this esp32_cam module.

    Many thanks, PP

    Reply
    • Hi PP.
      Most of the GPIOs exposed on the ESP32-CAM are either being used by the camera or by the microSD card.
      So, it will be very difficult to interface a LoRa module with this board.

  61. The dl_lib.h is related to the face recognition capabilities 2 (esp-face), and it was removed in version 1.0.3 of the Arduino core. That said, just comment it out and it should compile and work perfectly either if you are using the Arduino IDE. Other option is to revert to version 1.0.2 of the arduino core.

      A solution to the “esp_camera_fb_get(): Failed to get the frame on time!” message….
      Im using the ESP32-CAM Module 2MP OV2640 Camera sensor Module Type-C USB module from Aliexpress. Although not mentioned It doesn’t have the extra PSRAM the other M5 models do AND the camera has one changed IO pin. See here… https://github.com/m5stack/m5stack-cam-psram/blob/master/README.md and scroll down to Interface Comparison. The CameraWebServer Arduino example we’re probably all using doesnt have this ESP32-CAM model defined. You need to add it yourself eg in the main tab add #define CAMERA_MODEL_M5STACK_NO_PSRAM , and in the camera_pins.h tab add…
      #elif defined(CAMERA_MODEL_M5STACK_NO_PSRAM)
      #define PWDN_GPIO_NUM -1
      #define RESET_GPIO_NUM 15
      #define XCLK_GPIO_NUM 27
      #define SIOD_GPIO_NUM 25
      #define SIOC_GPIO_NUM 23

      #define Y9_GPIO_NUM 19
      #define Y8_GPIO_NUM 36
      #define Y7_GPIO_NUM 18
      #define Y6_GPIO_NUM 39
      #define Y5_GPIO_NUM 5
      #define Y4_GPIO_NUM 34
      #define Y3_GPIO_NUM 35
      #define Y2_GPIO_NUM 17
      #define VSYNC_GPIO_NUM 22
      #define HREF_GPIO_NUM 26
      #define PCLK_GPIO_NUM 21

      And you’re good to go.
      Also note that the max resolution of the bare ESP32-CAM Module is XGA1024x768 i assume also because of the lack of PSRAM.

      I don’t know what can be the problem.
      In this example, video streaming only works on one client at a time. This means that if you have the web server opened in another tab, it will not work. Just one tab at a time.

    I’ve backed up the firmware with esptool. Does anyone have a .bin file from a board that shows the toggle settings pane?

    • Hi Antonio.
      It may be the Wi.Fi signal.
      Are you using the on-board antenna or an external antenna.
      If you’re using the on-board antenna, you need to be close to your router. The best way is to have an external antenna.

    • I had a similar problem.
      The fact that you get occasional words suggests that the baud rate is right.
      I forget which problems that I had were solved by what, but I started out powering the module on the Vin pin and having a power line connected from the TTL and I ended up cutting all the power lines to the TTL and powering the module on the 5V pin.

    Please select CIF or lower resolution before enabling this feature!

    then when iam try to get low resolution QVGA (320 x 240)
    face detection and face recognition done

    1. how to make camera OV2640 with high resolution using face detection and face recognition ?

    when iam opnened the web IP Adress ESP32 Cam – button get still
    then iam check on program i cant find the button is
    2. how to make button “Get Still” – save to SD Card ?

    then the code checked the image when false detected 0
    3. how to read the image then checked the image scan detected=true ?

    like this web, when camera detect (show on micro SD Card – intruder alert)

  72. Is it necessary to connect to the ESP32 Cam using the FTDI Programmer? I have a USB/TLS cable, meaning one side is USB, and on the other are red (VCC) , black (gnd), white (TX), and green (RX) which I use frequently to connect upload to ESP8266 w/o the FTDI programmer.

    With the ESP32 Cam I tried connecting the USB/TLS cables as follows:
    Red > VCC
    Black > Gnd
    White > U0T
    Green > U0R
    No luck yet: there’s still the issue of getting the ESP32 into bootloader mode.

    There’s the Reset button, but I’m used the the ESP32 and ESP8266 where you need two buttons

    I’ve read you can get ESP into bootloader mode by grounding certain pins.

    Overall the question is: Can I flash the the ESP32 Cam using a USB/TLS?

    • Hi.
      The FTDI programmer we’re using has a mini-USB port. So, we just connect a mini-USB to USB cable to the FTDI programmer and then to the computer.

  75. Hello.
    When I Verify/Compile I get this space error. I’ve not even connected my ESP32.
    Sketch uses 2053883 bytes (156%) of program storage space. Maximum is 1310720 bytes.
    Your trouble shooting mentions (for a space different error)
    Tools > Partition Scheme, select “Huge APP (3MB No OTA)“.
    but I don’t have this in Tools.
    I’m using IDE 1.8.12
    Thanks.

  76. Thanks for the good tutorial, very helpful!

    I read that the logic level for the ESP should be 3.3 V!
    Not sure if you can fry your board with 5V logic levels.

    I had success using a FT232RL USB to TTL Serial Converter, using 5V from the side to power the ESP with cam and having the jumper set to 3.3V for the logic levels.

    Reply
    • Hi Thomas.
      You are right that you should use 3.3V with the ESP32-CAM.
      However, many of our readers had troubles when using 3.3V and those were solved when they used 5V instead.
      We didn’t have any problems when using one option or the other.

  77. Hey. Have you tried this camera as an IP cam (softcam)? With own name and IP address? I tried a sketch but I don’t get a video image but also no ip address provided via the Serial monitor. This sketch is in IDE. Do you know him?

  78. Dear Sir
    very good work, it works for me, but the problem it is not saving recognized faces to microsd-card. Each time power on we have to start recognition again.

    To make sure there is no problem with the microsd-card or the board I try this “https://randomnerdtutorials.com/esp32-cam-take-photo-save-microsd-card/” and it works and save photos to microsd-card.
    So where is the problem ???

  79. Hi,

    the installation went fine and when I enter the IP address (in chrome) I had video; also the integration with Home assistant went smoothly – so far so good.

    I however don’t have the “camera streaming server” with the config buttons and sliders and I can figure out how to fix that.

    Ideas / clues would be very appreciated.

      That can happen if the ESP32-CAM is continuously streaming, specially during face detection and recognition.

  82. Hi, thank you very much for your tutorials. My second project has been the the esp32 camera. Just for knowing: your tip of connecting GPIO0 to GND when flashing is very important and solved my problem of “fatal error…”

    Thanks

  83. I encountered A HORRIBLE problem and would like to share it with you folks with a solution of course 🙂

    Problem is:
    If you notice every time we have to press the RESET (RST) button to start our ESP32 CAM so that your program works…Now what if for some reason the power to ESP32 CAM board goes down? And say in 5 mins the power is back ON to the board..
    Will you go and press the RESET (RST) button over and over to get your program started ?
    How to let your ESP32 CAM board auto reload (call setup() function) when powered on without having to press the RESET (RST) button to get your code up and running.

    Answer:
    After you upload your code on the ESP32 CAM board, connect the GND wire to the GND pin  which is near the 5V pin of the board..Voila!!! This will solve your problem..
    This seems like a hardware bug linked to C15 on the ESP32 board..
    Hope this tip helps all folks…

  84. I have had a lot of trouble programming some ESP32 cameras which are not on the list of cameras in the software.

    I found that I can program those boards if I use an Arduino, instead of the FTDI cable. Doing this I can select the AI Thinker board. I have always had time outs when trying to use the FTDI cable.

    I just wanted to mention this for anyone else who is having trouble with the programming cable method.

  85. Hi Guys,
    I have two ESP32-CAM, both of then was working perfectly untill some time ago.
    Now, everytime that I upload a sketch to the modules, I get the this error message which is recurrently appearing here:

    [E][camera.c:1049] camera_probe(): Detected camera not supported.
    [E][camera.c:1249] esp_camera_init(): Camera probe failed with error 0x20004

    I don’t know what is going on, because it happens in my two ESP32-CAM modules and they were working perfectly here in the last time I used then.

    The labels n the ribbon cable in both OV2560 cameras are:
    XRZ00D1 -V240 V2.0 1903

    I tested here my ESP32-CAM modules (conecting to the Wi-Fi, without initializing the camera) and they are working fine.
    I tryed many things here, including powering the ESP32-CAM with an external 5V source, but nothing worked so far.

    Is there any way to test if the camera is working (without the ESP32-CAM module)?
    Any ideas?

  94. Have you seen the new esp32cam motherboard which is being sold on eBay very cheaply (search for esp32cam mb”?
    This is the only info. I have managed to find about it: hpcba.com/en/latest/source/DevelopmentBoard/HK-ESP32-CAM-MB.html
    It makes using the esp32cam so much easier as it functions just like any other esp32 development board with no wires, linking pins, removing power etc..
    The esp32cam does not have a reset pin and it seems the esp32cam supplied with the motherboard is a modified version where one of the GND pins has been changed to a reset when low pin despite still being labelled as GND.
    You can still use it with other esp32cam boards but you have to connect power whilst holding the program button to upload code.
    Mine will only work on slower serial upload speeds and the wifi signal is very poor whilst on the mother board (I am guessing this is why many of the suppliers offer the external antenna option) but well worth a look especially for first time users especially for the price.

    The problem is that the ESP32 heat up a lot and stop. So I can’t use them as 24/7 surveillance devices.
    I tried to lower the resolution from SXGA, to XGA, then SVGA but it’s not satisfactory.

    Am I the only one with this type of problem? Is there any way to stop these overheats?

  101. If anyone is having issues with the esp-32 CAM not coming out of sleep mode you have to change the 10K out for a smaller resistor size.

    There are some errors not talked about though that I don’t know how to fix like Timeout waiting for VSYNC happens randomly which requires turning the whole system off and on.

    Also one time my SD card was corrupted and I had to reformat it losing all the photos. Lastly the photos sometimes don’t come out right, like only the top of the photo comes in or the entire photo is unviewable. I think this issue may be caused by the camera going into sleep mode before the picture is done being taken though, so maybe increasing the delay time will fix it.

  102. Hi,
    ESP32-Cam is wonderful. It can be programmed with FTDI programmers of several kinds, however if I use an Arduino as a programmer (Tx to Tx and Rx to Rx) I have the following problem:
    With Arduino Duemilanove (FTDI driver) it works,
    Arduino Uno (CH340 driver) does not charge – does not communicate.
    I mention that:
    – ESP power supply is at 5V,
    – In series with Tx and Rx I put 1K resistors due to the voltage difference (3.3 – 5V) on the terminals.
    Does anyone have any idea.
    Thanks!

  111. Thank you for this tutorial! I bought a pair of ESP32-CAM from the same vendor. Packing says DFROBOT. Chip says ATHINKER, so I used ATHINKER successfully. Following the steps on “Getting started with the ESP32-CAM” I finally got 1 to work, one to kind of work.
    Couple of troubleshooting tips:
    1) Putting the jumper in the 5V position and connecting to the 5V pin allowed me to load the sketch
    2) If, after loading your sketch, removing the programming jumper, reattaching the USB cable, the initialization just ends with an endless line of “………” every few seconds, your SSID or password is wrong. SSID is case sensitive.
    My problem:
    I have 2 ATHINKER ESP32-CAMs. My first one will not stream, but will take a still shot. When streaming it shows a small blank square with a broken icon. The second one will stream just fine. Same sketch, wiring, computer, cable. Any ideas why?

I have a necessity of Video analysis and Photo analysis.

  114. Hi there,
    Can u tell how to read the frame rate (fps) of the ESP32-cam module. I am using one ov264 cam ( AI Thinker CAM ).

  115. hello Santos,

    please add to troubleshooting, if use ESP-CAM-MB with ESP32-CAM, ESP.getPsramSize() report 0 PSRAM and stream is incredibly slow.

    MJPG: 3972B 8169ms (0.1fps), AVG: 4106ms (0.2fps)

  116. Hi,

    Thank you so much for all your efforts!

    I have bought several ESP32-CAMS and when I load (the same) CamWebServer_Example sketch all works well on each but some show the image in portrait mode and others in landscape.

    Why is this happening with the same code and configuration? Are the boards different in some way or is the camera module itself wired up differently?

    I would like all to operate in landscape mode – is there any way to make this happen or are these boards permanently different and how can I tell which one I’m buying?

    Thank you for any help you can give me – it would be much appreciated.

  117. Hello,
    Thanks for this project, I have the camera up and running! I do have a question about integrating it with Home Assistant. I tried adding the picture card in my ui-lovelace.yaml file but the stream is not coming up.

    Here’s what I have:
    – icon: mdi:cctv
    title: Cameras
    cards:
    – type: picture
    tap_action:
    action: none
    hold_action:

    • Hi.
      The stream is only accessible to one client at a time.
      Close any other clients that may be connected to the ESP32-CAM video streaming.
      Regards,

  118. Hello, I’m thinking in a new project.
    I want to build a time lapse camera long term to record my house building.
    I think that programming the work hours and take any photos for a day.
    I want no attending camera or battery and catch the camera passing 8/9months.
    I read in the forum maybe don’t Support 32gb SD card… Isn’t it?.
    My project…. it’s possible?
    Thanks to all

    • It is possible when u connect ur esp32cam with arduino board and supply the power supply like solar pannel. But not sure for long term since the esp32cam get hot when long term stream?

  119. Hello Sara,
    I have one question to the ESP32-Cam:
    How can I rotate the picture 90 degrees? I cannot rotate the Cam in the case.

  120. You have written a great introduction. Thanks! Could the face recognition feature be trained to recognize a stationary logo (not a face) on a TV screen? Is there any gpio output when a face is recognized?

    Reply
  121. I’m wondering if the face recognition system could be used to recognise moods: can it tell a happy face from a grumpy one?
    I imagine that that would be easier than recognising different faces, but I have no idea how it works, so I wouldn’t know where to start.

    Reply
  122. I have got face recognition working after implementing a suggestion to download the ESP32 library to 1.04, the other suggestion to use 1.06 and edit the code did not work.

    Have you any plans to extend the tutorial to store and then load the data required for face recognition to the SD card?
    At the moment the information is lost when the board is re-powered?

    It is certainly something I will be looking into.

    Great tutorials.

  123. I want to get rid of the text output giving info about the video produced. It comes out in the serial monitor and I want to put other info there without it being cluttered by the video info. Do you know where the code is which is producing this. I can’t see it in the camera library files.

  129. Hi Sara,

    I tried this “mounting” with ESP32-cam, it worked almost perfectly.
    I say this because although I followed all the steps, it does not connect to my WiFi network.
    The connection data are the correct ones (SSID and Password).
    It generates its own WiFi network with the address 192.168.4.1 to which I connected both with my phone and with my laptop.
    Am I wrong somewhere?
    In the serial monitor after reset I receive the following:

  130. Hi there to all of you,
    Hi Sara,

    Nice tutorial. I made a “system” with ESP32 cam and one usb programmer, uploaded the code and surprise…. Won’t connect to my wifi network even if I gave the right credentials. It’s working on my phone and on my laptop (after I connect my laptop to the wifi network generated by esp32). That was yesterday, today at work, I realized that the ESP32 have a resident software inside and my code doesn’t upload. Why I am saying that? Simply because I forget to put IO0 to the ground. I soldered 7 pin socket 5 for USB programmer and 2 for a jumper, but I didn’t connect to ESP32…. My fault…. This evening I will make all connection “by the book” and try again. So the idea is that ESP32 have some program resident “by default”, which will be over written by us in the uploading process from Arduino IDE ..

  134. Hi Sara
    Thanks for the great tutorials and projects.

    I can get the code uploaded and obtain the IP address for CameraWebServer, but when I try to connect via the browser with the IP address, there is no connection. There is no error message, just unable to connect to the CameraWebServer. After I uploaded the code, I got the following msg on the Serial monitor below, but there is no “Starting web server on port: ’80’ & Starting stream server on port: ’81’ ” msg in between, does that mean the CameraWebServer never got started and hence the no connection problem? If that is the case, what could be the source of the problem.
    “….
    WiFi connected
    Camera Ready! Use ‘http://XXX.XX.X.XXX’ to connect ”

    Thanks and Happy Thanksgiving.

    • Hi.
      What ESP32 board are you using?
      Please note that due to an update on the ESP32 core, the face recognition no longer works on “regular” ESP32-CAM boards. Only on ESP32-CAM boards with the S3 chip.

  139. I used this project (with some modifications) at work with success, got praises for that project.

    We need to port this project on a raspberry Pi with apache. I made a modification so that streams can work with a camera module.

    I would need some clue about controlling GPIOs, serial port and I²C port. Ideally I would reuse the Arduino code in C++, but I don’t know much.

    How can I use apache with some C++ code for the hardware I/Os?

    The only thing I could think of that could be the problem is that I’m using an Arduino uno bord instead of the FTDI programmer. Is that the issue or is it something else?

  143. Good day,
    I like this Cam Webserver much as a base of my projects.
    No I have to include OTA and found your basic project about such.
    But trying to include ElegantOTA (using v3) in the Webserver I fail (due to lack of knowledge I must say).
    Either I get the CamWebserver or the Elegant OTA running but not both.
    Do I start with the asyncOTA webserver and include the Camwebserver or vice-versa (which I understand would be the process).
    So my lack is probably where to put the ElegantOTA process and definitions in.

    Do you have an advise how to integrate.
