Outdoor Mirror Detector with Anti-masking

TOWER-20AM® is a ground-breaking, anti-masking mirror detector that provides unparalleled alarm detection in outdoor environments due to the unique patented technologies it employs. It is the first detector to prevent false alarms caused by outdoor interferences, such as rain, snow, lightning storms, swaying bushes and free-roaming animals, while still providing reliable detection of real threats.

TOWER-20AM features the revolutionary Octa-Quad technology which uses eight PIR sensors, as compared to only one sensor found in other outdoor detectors. Each sensor acts as a Quad detector to accurately determine whether an alarm is justified. In addition, to further increase reliability, TOWER-20AM has a robust housing and patented anti-masking protection that can distinguish between masking spray, rain and sprinkler irrigation, providing an exceptionally high resistance to vandalism and masking.
