A Remote Area Monitoring System (RAMS) for detecting movement in a disallowed direction through a passageway (P). The RAMS monitors two volumetric spaces that are established by the system, both of which spaces are defined with respect to depth, width, and height. Both a warning zone and an alarm zone are defined for each space. The warning zone protects against inadvertent incursion into the protected spaces; while the alarm zone protects against intentional intrusions thereinto by movement in the disallowed direction. The RAMS automatically monitors both zones and does not require human vigilance to detect and warn of an incursion or intrusion. Human traffic, in both directions through the zones, is monitored; as well as the movement of objects. Movement of humans is detected using a sensor (16) employing machine vision technology including multiple overhead modules (12) linked together so to cover the passageway through which pedestrians travel. The zones covered by the modules overlap so to insure that there are no gaps in coverage. A sensor (18) employs near infrared (IR) imaging techniques to detect thrown or tossed objects. A workstation (20) includes a display (52) where alarm events are recorded and logged. The workstation also includes recording (34) and printing (36) equipment to aid in apprehension of an intruder.
