Methods provide surveillance, including a modified video data stream, with computer readable program code, when read by a processor, that is configured for receiving at an image processor a first video data stream and a second video data stream. Each of the first and second video data streams may include a target object having an assigned tracking position tag. The methods may further include extracting a first facial image of the target object from the first video data stream, determining a target object location in the second video data stream based at least in part on the tracking position tag and generating a modified video data stream including the first facial image superimposed on or adjacent to the target object location in the second video data stream.
