A smart Android based remote monitoring system This paper proposes a smart, easy-deployed remote monitor system based on Android system. Different from normal monitor system, what you need to deploy the monitor system are only a camera, a PC with Linux system and an Android smart phone, which is commonly held by people. The system is based on the open-source library live555, FFmpeg and x264, thus it is readily extendable. In this system, the video is recorded using V4L2 interface and encoded by x264. The live555 media server then forwards the video stream over RTSP to the client. Finally, the client decodes the video and plays it. Performance test shows that this system has the basic function of remote video recorder and can work smoothly.
