Video monitoring optimizing method and device

The invention provides a video monitoring optimizing method and device. According to the limit of authority levels of users, the importance degrees of the users at a moment T and camera weight values, call weights of the users are calculated; according to the call weights, the users are ranked; within the total permissible call bandwidth range, the front users are selected as many as possible. Thus, the video monitoring bandwidth use rate is maximized, and meanwhile video call conflicts are avoided.
