Abstract: A system for tracking objects, in which each object has a wireless connected tag attached to it, and a motion detector. The tags transmit the identity of the object to a tag reader only when object motion is detected. The system includes an optical imaging system for surveilling the area, which optically detects and characterizes any motion in the area. The system control unit correlates the information from the tag reader and the optical motion sensor and thus associates each tag detected wirelessly to the optically detected motion, such that the identity of the optically detected motion is determined even without clear optical identification. This correlation may be performed by comparison of the time of detection of information from the tag reader with that of the optically detected motion. The system can be used in tracking objects such as toys whose identity cannot be determined by visual imaging.
