This document describes a smart and low-cost surveillance system using a Raspberry Pi, USB camera, PIR sensor, and motion detection algorithm. The system is designed for highly secured areas and overcomes issues with traditional CCTV like high storage requirements and 24/7 monitoring needs. When motion is detected by the PIR sensor or camera, the system sends a short link to the user's phone to view the live video stream. It also saves images for review and uses motion detection to only store images where motion occurred, reducing storage needs. The system is intended to provide a secure, affordable, and efficient surveillance solution.
