## Warnings
- For some reason the ESP board I am using is getting offline after long run.
A dirty workaround is in place forcing the board to reset every MAX_RUNNING_TIME (see in **CameraWebServer.ino**)
- If you encounter some "brownout" message when using 3.3V you can work around the issue using 5V input (It worked on both of my ESP boards)
- The frame rate is display only if an active connection is here, if your client is far for the WiFi network framerate will be lower.
- The frame rate which can be achieved:
  - With 320x240 framerate should be around 25fps
  - With 640x480 framerate should be around 12fps
  - With 800x600 framerate should be around 12fps too
  - With 1024x768 framerate should be around 6fps
- If you have a client with a good WiFi connection and you cannot achieve the framerates above, please check if it improves by pinching the WiFi antenna to the PCB (I personally use a rubber band for this :) ).

## Installing
Do not forget to shunt the **IO0** pin to **GND** for flashing, remove the jumper after flash.

### Board Configuration
- Board: **ESP32 Wrover Module**
- Upload Speed : **921600**
- Flash Frequency : **80MHz**
- Partition Scheme : **Huge APP (3MB No OTA)**


### Configuration
- Define your desired reboot timeout **#define MAX_RUNNING_TIME**
- Insert your WiFi SSID(s) and password(s) in **ssid_list_t aplist**. The list **MUST** end with **{NULL,NULL}**
- Compile and upload

## Webserver
The webserver can only handle 1 connection at a time.
