Re: Cheap WiFi Webcam: ESP32 + OV2640 camera

Hey,

I found this topic and was quite interested to add a camera to my Duet 2 Wifi.

From an old project I hat an (AI-Thinker) ESP32-Cam module lying around. It is about 8€ at ebay shipping from Germany. If you order from china the module is quite cheaper.

I found this tutorial to convert the ESP32-Cam to a surveilance camera, but the stream works for duet very well.

So follow the tutorial, insert your wifi credentials at line 28+29 and change the resolution at line 230. Forme these settings worked very good with DWC:

if(psramFound()){
   config.frame_size = FRAMESIZE_SVGA;
   config.jpeg_quality = 10;
   config.fb_count = 2;
 } else {
   config.frame_size = FRAMESIZE_SVGA;
   config.jpeg_quality = 10;
   config.fb_count = 2;
 }

Here you can find some information about the possible settings:

At DWC you just have to past the IP adress at Webcam-URL field like this: http://192.168.178.153/
After flashing start the serial monitor in Arduino IDE to find out your IP.

That's all
