1. The document describes a Raspberry Pi-based security system that uses a CCTV camera to detect accidents on roadways in real-time and automatically sends alerts to ambulances. 2. The system analyzes video from the CCTV camera using computer vision techniques to detect accidents. When an accident is detected, it sends an alert message via GSM/GPRS to notify ambulance services. 3. The system aims to reduce response times for accidents by automating detection and alert compared to passive CCTV monitoring, in order to save lives.
