Traditional door security systems are often vulnerable to tampering and lack modern capabilities such as remote access and real-time monitoring. This project aimed to design and implement a cost-effective, Internet of Things (IoT)-based door security system that integrates proximity detection, live camera feed, and remote access control to address these limitations. The system was built using an ESP32-CAM microcontroller for Wi-Fi connectivity and video streaming, an HC-SR04 ultrasonic sensor for proximity detection, and a servo motor for the locking mechanism. Additionally, a custom mobile application was developed using MIT App Inventor to serve as the user interface. The prototype successfully demonstrated functional reliability, enabling real-time monitoring via live video feed, remote actuation of the door lock, and visual feedback through an LED indicator. Consequently, this research provides a scalable, user-friendly solution that bridges the gap between advanced security features and affordability, demonstrating how low-cost, open-source technology can be effectively utilized to create robust IoT-based home security systems.
