In order to improve the mobility of the traditional video surveillance system, this paper presents a design system based on embedded video monitoring, the system has a high performance data processing, taking ARM11 core processor and embedded Linux as the operating system. Video obtained by the CMOS camera, video data is compressed by the WiFi module sends to the PC, PC client machine using C++ language in the Qt platform based on H.264 format. Clients achieve a real-time video playback and video images intercept feature, you can make some of the video screen resolution, brightness and other settings, the interception of images to JPG format. Monitoring center using Qt to develop client and uses multi-threading technology, can significantly improve CPU utilization, make the software run more smoothly lower system power consumption. The system has a good user interface, excellent portability, mobility and low power consumption advantages, can be widely
