Active video surveillance system and active video surveillance method therefore

摘要

An active video surveillance system and active video surveillance method therefore of the present invention mainly is provided to continuously taking the wide-angle image signals within a surveillance area by an image-taking device, and a processing device is employed for continuously comparing the latest and the second latest wide-angle image signals. Then, a moving target is identified when a difference occur there between and the image-taking device or a second image-taking device is immediately driven to take the enlarged image signals of the moving target, and the said wide-angle image signals and the said enlarged image signals are recorded into a recording unit. By using the above-mentioned design, the video surveillance system is able to enhance the definition and identification capability of specific moving targets.
