Industrial sites/public places/road traffic remote tele surveillance intrusion detection having video camera output reference compared and spatial movement transform with output set level compared.

摘要

The intrusion detection method has a video camera (C) providing video images. A resultant image is calculated between a current and reference image. One of the images is formed into blocks and transformed to determine spatial activity. A digital intrusion detection is then compared with a set level (12) to raise an alarm.
