ACTIVE CAMERA VIDEO-BASED SURVEILLANCE SYSTEMS AND METHODS

摘要

A video surveillance system comprises a sensing unit (21) capable of being operated in a first mode and second mode and a computer system (22) coupled to the sensing unit (21). The computer system (22) is adapted to receive and process image data from the sensing unit (21), to detect and track targets, and to determine whether the sensing unit (21) operates in the first mode or in the second mode based on the detection and tracking of targets.
