Smart Surveillance System

This project presents an innovative smart surveillance system that combines real-time security monitoring with environmental tracking while prioritizing energy efficiency. The system integrates an ESP32-CAM AI-Thinker module for visual capture, a PIR motion sensor for activity detection, and a BME280 sensor to measure temperature and humidity levels. A unique feature of this setup is its Telegram-based remote-control interface, which allows users to interact with the system seamlessly from anywhere. When the PIR sensor detects movement, the system automatically captures images and sends immediate alerts to users through Telegram, ensuring prompt notification of potential security events. Beyond security, the system continuously provides real-time environmental data, enhancing overall situational awareness. Designed with sustainability in mind, the solution utilizes solar power with Li-ion battery backup, supported by efficient power regulation through LM2596 and LM7805 voltage regulator circuits. Unlike traditional CCTV systems that operate continuously and require substantial storage capacity, this intelligent system only activates when motion is detected, significantly optimizing both power consumption and storage requirements. The integrated Telegram bot extends functionality by enabling users to manually request images, check current sensor readings, and control various features like the camera's flash control. By combining smart detection capabilities with low power consumption and remote accessibility, this system offers a practical, cost-effective, and environmentally friendly security solution suitable for residential and restricted area applications.
