This project is a home security system that uses a Raspberry Pi and a camera, which detects human presence and sends a message with a picture of the intruder. The system checks connected mac addresses, and if a protector (household member) is home, closes the home security system.
- Raspberry Pi (an embedded computer)
- Camera (can be anything, I use an old webcam)
