ESP32-CAM Face Recognition Door Lock System

Introduction Smart home security has evolved far beyond traditional locks and keys. In this project, we build a face recognition-based door lock system using the ESP32-CAM module. This system identifies authorized individuals and unlocks the door automatically—no keys, no cards, just your face. The ESP32-CAM is a powerful yet affordable microcontroller with a built-in camera, making it ideal for IoT-based vision applications. Combined with its onboard Wi-Fi, it enables real-time face detection and recognition directly from a web interface. How the System Works The system captures live video using the ESP32-CAM and processes it to detect and recognize faces. Once a face is recognized, the microcontroller triggers a relay module to unlock the door. Here’s the flow: The camera captures a live video stream. Faces are detected in the frame. The system compares detected faces with stored data. If a match is found, the door unlocks. If not, access is denied. All of this happens in real time t
