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.
