ESP32-CAM with motion sensor

This code turns the ESP32-CAM into a security system with motion detection:

The ESP hosts a WebServer that provides the camera stream and a WebSocketServer that is used to communicate commands between the Android app and the Esp. It also sends a notification to the Android app with an image when it detects motion.

Usage

As soon as the ESP has been flashed with the firmware, it sets up its own "ESP camera" wifi network. A wifi-enabled PC must now connect to this network. Once connected, the address http://192.168.4.1/ can be loaded in the browser and the ESP lists all available networks and you can choose one of them to connect to. When the ESP is connected, this is visually displayed in the browser and the ESP automatically restarts and connects to the wifi. Now the Android app can be installed and started. All further instructions can be found in the app.
