ABSTRACT OF THE DISCLOSURE In a passive infrared intrusion detection system, a signal responsive to infrared radiation received from optically divided zones of an area to be monitored is integrated to produce an integral sum. The integral sum is used to generate an alarm indication. The alarm indication is thereby rasponsive to the energy of the signal responsive to the infrared radiation received thus improving sensitivity of the detection system without increasing susceptibility of generating a false alarm.
