An AI-powered security gate that opens only for authorized faces. A camera captures the visitor’s face, the controller (OpenCV on Raspberry Pi or ESP32-CAM) detects/recognizes enrolled users, and the motor driver opens the gate for a set time before closing automatically. Unknown faces keep the gate locked and can trigger a buzzer and snapshot/alert. Includes manual override and limit switches for safety. Ideal for homes, offices, hostels, and small societies.

Parts Used:

1. Raspberry Pi 4 / ESP32-CAM – runs face detection/recognition
2. Camera Module / USB Webcam – captures live video at the gate
3. Motor (DC geared / actuator / servo) – drives gate or latch
4. Motor Driver / Relay (L298N, relays) – controls motor direction/on-off
5. Limit Switches (Open/Close) – position feedback and auto-stop
6. Power Supplies – 5V for logic, 12–24V for motor (separate rails)
7. Buzzer / LED – alerts on unknown face or errors
8. Emergency Stop & Fuse – safety and circuit protection
9. Optional IR LEDs – better night performance
10. Optional LCD/OLED or Web UI – status display and user management
11. Wiring, Connectors & Enclosure – reliable connections and weather protection
