Abstract: This paper proposes a design scheme of mobile video surveillance system based on WiMAX. It gives the hardware design of front end, chips and the wireless network interfaces. Double buffer and intelligent code rate control policies are used to assure the quality of video when network bandwidth changes or sector switchs in WiMAX. Experimental results and application effect of the system show the validity of the design scheme.

Key words: WiMAX, video surveillance, mobile video surveillance, rate control
