I setup a small RPI-zero camera, in order to know what's happening at my front-door and drive-way.

The setup runs on motionEyeOS and is only available in my LAN network. Any movement inside the camera's view is automatically detected and starts recording to the local SD-card. I added an additional script, that uploads the first video frame as image to a private Discord server as backup. This also provides an update, whenever someone's at the door when we're not home.
