This paper proposes a technique to detect abnormalities in the video surveillance based on motion trajectory. Proposed technique is based on the nature of the route has a certain influence on objects moving on that route, thereby we given a representations routes by segments, combined used Hausdorff distance to calculate the similarity between trajectories. Therefore, the proposed technique can detect abnormal, even when the object is not complete orbital motion, thus the system can response the video monitoring real-time.
