Design of mobile phone video surveillance system for home security based on embedded system

摘要

As the speedy development of national economy and the escalation of living standard, people's awareness of Home Security is increasing day by day, the demand for the convenient, mobile and real-time alarm video terminal is rising rapidly. Based on the development of embedded network technology and intelligent mobile phone used widely, the design for Home Security is put forward, which consists of the embedded camera for monitoring front and the intelligent mobile phone for monitoring terminal, finally to realize video monitoring through the mobile device. The monitoring front of system: S3C2440 microprocessor is selected as the hardware core of embedded system, Linux is selected as the embedded operating system, whose function is for coding and compressing the real-time image. The system's network part adopts China Unicom's WCDMA Technology and the RTP/RTCP protocol of supporting transmission of streaming media, whose function is for transmitting and packing data. Intelligent mobile phone is used as the monitoring terminal, whose function is for receiving and displaying data. Through the preliminary analysis and verification, the design is reasonable and can achieve the desired requirements.
