This project involves building a "smart" video camera using a Raspberry Pi, a web camera, and the Vonage SMS API. The camera detects humans in the frame and sends an SMS notification to the user if a person is detected, allowing for real-time monitoring of potential security threats. The object detection algorithm used is the Haar classifier, which requires training with positive images (people) and negative images (non-people). The project uses OpenCV libraries for image processing and the Vonage API for sending SMS notifications. With this system, users can receive alerts if someone is detected on their property, providing an added layer of security.
