A sensor-based system includes a number of sensors, each of which generates a sensor signal, and a processing system coupled to the sensors. The processing system processes the sensor signals received therefrom to generate a representative presence video signal suitable for presentation on a display. In an illustrative embodiment, one or more of the sensors each corresponds to a camera which generates a video signal. The processing system in such an embodiment is operative to compare at least a portion of each of the received video signals to stored information representing one or more patterns, to determine representations corresponding to one or more of the patterns detected within the video signals, and to generate the representative presence video signal such that it includes one or more of the representations. The representations in the output video signal may be indicative of normal or abnormal activity detected in the video signals generated by the cameras.
