In order to improve the mobility of the traditional video surveillance system, this paper puts forward a design of embedded video surveillance system based on 3rd generation mobile telecommunications. This system has high performance in data processing by taking ARM11 as the core processor and the embedded Linux as the operating system. The video was obtained by the CMOS camera. And then, the video data w as compressed according to the H.264 recommendation and transmitted by the 3G module. Because of the advantages of portability, mobility and low power dissipation, the system can be applied in many situations such as filed construction and temporary construction.
