The design scheme is constructed based on ARM9 microprocessor S3C2440A hardware core, embedded Linux operation system software platform, through the USB drive and the video4linux2 implementations made by USB camera mesh 2000 YUV420 format video image data. The design principle and application of the research contents include ARM9 development board, the principle and application of the second generation GSM munication, the application of embedded Linux system and camera video image acquisition, web web client application, the HTTP request and response analysis. Aimed at the problem of the large amount of video image data at the same time, the MJPG - the streamer images on video streaming to realize transformation of image data transmission, through the multithreaded programming, under Linux based on TCP/IP Socket programming send video data, for remote transmission of the data bring convenience. This design gives the key functions of the software implementation method, c
