Esp32 cam

Malakian

Hello,

I'm asking for your help about the esp32 cam module.

My aim is to use a little camera in my garden et watch the stream through MotionEye.

The problem comes from the esp32 cam module.

To be honest, I thought it will be easy by watching tutorials but in fact it is not.

I bought a set of two. They are from Diymore brand.

Chip Info:
 - Chip Family: ESP32
 - Chip Model: ESP32-D0WDQ5-V3 (revision 3)
 - Number of Cores: 2
 - Max CPU Frequency: 240MHz
 - Has Bluetooth: YES
 - Has Embedded Flash: NO
 - Has Factory-Calibrated ADC: YES

My approach is described below.

1) Connect the esp32 cam to a programming interface (it was sold with the module)
2) Connect all to an usb port of my pc
3) Download the firmware tasmota32-webcam.bin
4) Launch the ESP_Flasher software
5) Install the firmware on the esp32 cam
6) Connect the pc to the esp32 cam access point
7) Go to esp32 cam page (192.168.4.1)
8) Fill in the domestic wifi parameters
9) Connect to the esp32 cam via the domestic wifi network
10) Go to "Configure other"
11) Change the template by the one fond on templates.blakadder.com/ai-thinker_ESP32-CAM.html
12) Activate and save
13) Relaunch the esp32 cam

I can do all theses operations but if I use the last firmware version (12.5.0), I have no video from the camera (0 fps).

I I use another firmware version (12.4.0), I can have a video from the camera but it freezes in a very few time or the frame rate is very low (1 fps).
Moreover, I have no video settings possibilities on the module web interface while it can be done on the tutorials I saw.

Can someone help me to make it work ?

Subsidiary question : I managed to flash on windows but it's impossible on Ubuntu, I can not get the port.

    The ESP32 doesn't have any video interface, nor any video acceleration features. I don't know what your expectation is, but very low frame rate sounds pretty reasonable depending on if the resolution is set high or if whatever else the software is doing is resource-intensive. It's a $9.99 board. It's never going to be very good compared to a normal streaming camera (which will compress the data using modern protocols).

    Regarding:

    " I use the last firmware version (12.5.0), I have no video from the camera (0 fps)."

    This too is normal if you're using pre-built firmware, unless you use identical hardware to what the author did. That's the problem with pre-built firmware.

    Regarding "I use another firmware version (12.4.0), I can have a video from the camera but it freezes in a very few time or the frame rate is very low (1 fps"

    That's due to the firmware again. You're using pre-built firmware, you'd need to talk to the author to find out precisely what hardware they used; what manufacturers sell may have subtly changed! Or, there may be bugs in the firmware. There's nothing you can do about that if you can't debug and rebuild it yourself.

    I'd also like to mention that most ESP32 projects are documented very poorly (I have not checked the one you're referring to), which is unfortunate given how good the ESP32 is as a device (albeit not for video! it has no video features). You'd do better to use a different board, such as a Pi, which will have better documented projects.

    Hello Shabaz,

    Thank you for your answer.

    I understand I can not expect a great result but I think 0 or 1 fps is not what you can expect from the esp32 if I follow the tutorials I have seen Slight smile

    On these tutorials, everyone use Pre-built firmwares.

    Maybe I made mistakes with procedures or the hardware I use could have issues but I don't know the esp32 cam enough to be sure.

    That's why I'm asking help.
