ABSTRACT:
Improved alarm system that is able to distinguish intrusions by persons from intrusions by others, such as nonhuman animals and inanimate objects. Multiple sensors are placed in a vertically aligned array, so that each sensor monitors at a different elevation. As animals and other objects generally have different sizes and shapes than humans, the vertically spaced sensors will detect different intrusion patterns than the intrusion patterns typically generated by a human. By analyzing these different intrusion profiles and only signaling an alarm when a profile resembling an intrusion by a person occurs, a number of false alarms can be avoided.
