Abstract

An apparatus for effecting surveillance of a space beyond a barrier includes: (a) a plurality of sensor devices; (b) a combining unit coupled with the plurality of sensor devices; and (c) a display unit coupled with the combining unit. The combining unit receives a respective sensor signal from each respective sensor device of the plurality of sensor devices. Each respective sensor signal indicates a sensed condition in the space. The combining unit and the display unit cooperate to display at least one displayed signal representing at least one of the respective sensor signals indicating movement of an object within the space.
