This document describes the design of a home surveillance system based on the Android platform. The system consists of a server and client. The server captures video, encodes it using H.264, and transmits the data to clients over RTP/UDP. It also performs face detection to save critical frames. The client receives the data, decodes it using FFmpeg, and displays the video. The system aims to monitor elderly family members and provide emergency alerts. It offers mobility through Android devices and stable wireless transmission.
