The system based on the ARM embedded system platform, uses the Linux operation system, uses the USB camera to carry on the capture for the supervising region image, then through the wireless network(802.11), the video signal transmitted to supervising terminal (PC). The resolution of the supervising image may achieve 320x240, above the frame frequency 20/second or 640x480, the frame frequency 5/second. In the system integrates image processing technology intelligent algorithm, can supervising and discrimination the movement in the region, can satisfy the general video supervising request. The system price is low, according to the different application can change intelligence supervising algorithm, the system has the broad p...
