Astract：This system is composed of hardware and software.Arm processor is used as the
controller of the system.By choosing proper chip,we design an embedded system.Acquiring
video device is VIMICRO camera,which is very popular on the market. Wireless transmission
device is wireless network card, the transmitting speed of which is 54M in no obstacle
environment. Operation system is Windows CE,which is Microsoft's production. It is designed based on many modules and very easy to use. The program running on the Arm board can open the camera, initialize it,acquire picture,close, so finally realized the image wireless transmission.
Key words：Video Acquiring , Embeded system ,WinCE,Arm9
