Abstract: The present invention is directed to systems and methods which monitor weights applied within a protected premises and, based on detected weight pressure patterns, serve to control operational aspects of the premises. In one embodiment, the pressure monitoring system is used in conjunction with a security system to resolve ambiguities in detected breach conditions. In one embodiment the pressure monitoring system learns and remembers how the premises is used. When a possible trouble condition is detected the system compares a detected pressure against known normal, known abnormal, and unexpected pressures to determine the action to be taken at that time.
