Abstract: This project is entitled as “IOT BASED SMART ANTI-THEFT SECURITY SYSTEM” is a IOT based application. The IoT-based Anti-Theft System proposed here integrates NodeMCU, Ultrasonic sensor, and ESP32 Cam to create a robust security solution. The core concept involves detecting unauthorized individuals through the Ultrasonic sensor, capturing their faces using the ESP32 Cam, and subsequently storing the images on an SD card. Additionally, the system is designed to automatically send the captured images to the owner via email. This project aims to enhance security measures by leveraging IoT technologies. The NodeMCU facilitates connectivity and data exchange, while the Ultrasonic sensor serves as an effective means for person detection. The ESP32 Cam, equipped with facial recognition capabilities, ensures accurate identification and capture of potential intruders. Storing the images on an SD card provides a local backup, ensuring that evidence of unauthorized access is preserved. Simultaneously, the email feature enables real-time notification for the owner, allowing prompt action in response to security threats. In summary, the IoT-based Anti-Theft System combines hardware components and connectivity to create an intelligent security solution capable of detecting and capturing potential thieves, providing a valuable layer of protection for property owners.
