ABSTRACT:
A motion sensor has a parasitic response to at least one of radio frequency (RF) or electromagnetic (EM) impulse signals. The motion detection circuit for security systems has a dummy RF receiver for generating an RP response signal, the receiver having a response to at least one of radio frequency (RF) or electromagnetic (EM) impulse signals similar to the parasitic response. An alarm output signal is generated in response to intruder motion in the predetermined area while preventing false alarms due to the parasitic response.
