Based on B/S architecture

a full range of motion image detection and alarm systems is designed. Linux system is translated into ARM11 platform as the operating system platform. Via USB camera capture front-end image

the collected image were sent to moving target detection module. Using image sequence frame difference method to detect whether a moving object exists

in order to prevent the emergence of false alarms.The background reference frame were update timely. Then the image data were compressed by H.264 compression module

and the compressed image data is transmitted to the client for decoding display; and client end uses CGI dynamic web technology to control monitor behavior. Experimental results show that the monitoring system can accurately detect the moving target

and the image is clear

smooth PTZ control

which can fully meet the user's daily requirements

and can be widely used in transport

schools

banks

supermarkets

buildings and some important events.
