Overview

This project demonstrates a Raspberry Pi-based smart home security system prototype. It integrates hardware components such as LEDs and a passive buzzer, paired with a Python GUI built using PySimpleGUI. The system supports face recognition and licence plate recognition, providing visual and audio feedback through GPIO components. Real-time alerts, including captured images, are sent via Telegram.

Key Features

• Face Recognition Module

  Controls green LEDs and a buzzer to indicate authorized access. Blink detection (EAR) is implemented to validate liveness before triggering actions.

• Licence Plate Recognition Module

  Controls yellow LEDs to indicate detection events. Each detection (authorized or not) results in a notification with the plate number and image.

• Real-Time Notifications

  All detection events trigger alerts sent through Telegram, with images and relevant info.

• Custom GUI Interface

  Built using PySimpleGUI, the GUI includes:

  • Upload Face
  • Tax the Face (Start recognition)
  • Monitor the Office
  • Open Face Log CSV
  • Exit
