In this article,an inteligent intrusion alarm method for multizone video monitoring was explored.The method which is based on multithread technology adopted the motion detection algorithm which is based on mixed Gaussian background modeling to realise real-time multizone intrusion alarm;the embedded function library of the video monitoring card was adopted to display the monitoring video;in the paper the interception of video data flow and conversion of data format were finished through clipboard,repeated reading and writing of the hard disk were avoided,the monitoring picture quality and the processing speed of the program were improved.At last the experiment's result was got,and the result shows that the method can do detection alarm to intrusion object with high effeciency and low false alarm rate,between 1%~2%.
