Method, system and program product for a plurality of cameras to track an object using motion vector data

A method, system and program product in accordance with the preferred embodiments use motion vector data to track an object moving between areas being monitored by a plurality of video cameras. Motion vector data are used to predict whether an object in a first field of view covered by a first camera system will enter a second field of view covered by a second camera system. If the prediction is that the object will enter the second field of view, tracking data are provided to the second camera system. The tracking data may include pan, tilt and/or zoom adjustment data, which may be provided to a PTZ adjustment mechanism of the second camera system, for example. Alternatively, or in addition, the tracking data may include pan/tilt motion vector data, zoom factor data and/or shrinkage/expansion data, which are provided to a motion tracking processor of the second camera system.
