Interactive video surveillance method

摘要

The interactive surveillance involves using at least one video camera 2 to monitor or observe an object or individual A. Digital data (2a) from the camera arrangement (A/D) is transmitted to a control computer 3. The computer identifies movement of the observed object and issues commands to vary the zoom lens 5 and the position 4 of the camera, so as to track the movement of the object. The recognition of movement in the monitored area may be used to initiate optical, acoustic or electrical alarm signals.
