Following some suspected feline break-ins, instead of closing the cat flap I set up a motion sensing night vision camera using a Raspberry Pi Zero W (~Β£20) and a camera module with infrared torches (~Β£20). The camera is running 24/7 and executes a script uploading video to Dropbox using the Pi's onboard WiFi. This page is a work in progress so the camera link below may be intermittent. πŸ¦‡πŸ“ΈπŸˆ

The video shows a cat successfully detected through motion detection, and the image shows a diagram of the constructed night vision camera. Below is the (intermittent) link to the camera stream.
