Abstract
An apparatus and method of processing signals from a passive infrared sensor evaluates energy of received signals. An integration or accumulation process can be used to provide an indicator of signal energy. This indicator can be compared to a predetermined alarm threshold to determine if an alarm indication should be generated.
