The IQ Motions is one of the most reliable ways to detect intruders. Often called your "2nd line of defense, " if someone manage to get past your sign, door sensors and glass break, they will not defeat the motion sensor
The IQ Motion is designed to be your last line of defense. If an intruder manages to get past your other sensors, he cannot escape the IQ motion! Programmed to detect infrared heat in bodies over 40 lbs. Typically installed pointing AWAY from windows (to reduce false alarms) the IQ Motion has a range up to 35 feet*. The IQ Motion can be installed two different ways: to cover an entire room from floor to ceiling or in a "pet sensitive" position, allowing animals under 40 lbs to pass under the beams without triggering the alarm.
* They cannot "see" though walls or doors
