40 x 40 Pet Immunity PIR Detector

Connect a motion sensor to your security system for immediate, accurate alerts when an intruder is detected in your home. With its 40' x 40' wide angle with 80' curtain pattern, the 40 X 40 Pet Immunity PIR Detector will keep an eye on a broad area of your home when your security system is armed, and unlike many standard motion detectors, this smart sensor won't be fooled by pets or other non-human movement.

The 40 X 40 Pet Immunity PIR Detector offers a multitude of features that prevent it from delivering false alarms. Optical Quad Zone Logic provides pet immunity to eliminate false alarms from objects 16 inches tall or less, while the 40 X 40 Pet Immunity PIR Detector also rejects false alarms caused by spot temperature changes such as small-to medium-sized animals, air conditioners, or moving curtains. Its high-quality spherical lens and dense detection pattern give the motion detector pet immunity superior to single-technology sensors.

This motion sensor detects IR energy changes in multiple areas and then couples them for extremely accurate detections. Quad Zone Logic provides multi-segmented detection zones over the detection area. It is designed so that a human-size target will normally fill 4 to 8 zones, and this will cause an alarm to be generated. Any smaller temperature change (i.e.: small-to medium-size pets, rodents or moving curtains) only activates one or two zones at the same time, creating a much weaker detection signal. Pet immunity applies to animals 0 to 16 inches in height. These signals are further analyzed by the "ECO" chip and signal processing circuit for accurate detection of humans and avoidance of most small animals.

Additional features include a sealed housing, which prevents drafts and insects from reaching the pyro element of the motion detector. For extra protection, try the 40 x 40 PIR/Microwave w/Pet Immunity Motion Detector, which also incorporates microwave technology with noise reduction to eliminate interference."
