Key Features & Benefits

• 12m 90° Detection: Provides a wide coverage area perfect for corner mounting to overlook entire yard spaces.

• Pet-Friendly Low Mount: By utilizing dual-layer PIR technology, the sensor ignores small animals moving along the ground, ensuring your pets can stay outside without triggering false alarms.

• Active Anti-Masking (AM): Detects if the sensor has been covered, sprayed with paint, or obstructed by an object, sending an immediate notification to your AJAX system.

• Digital Double Layer Detection: Both the upper and lower PIR zones must be triggered simultaneously to confirm an intruder, effectively filtering out alarms caused by swaying bushes or moving shadows.

• SMDA Logic: The Super Multidimensional Analysis engine evaluates every detection against a database of environmental patterns to eliminate nuisances caused by weather changes or light reflections.

• Ready for AJAX: Includes the AJAX TX internal module for full compatibility with the Jeweller radio protocol, allowing for easy “scan-to-add” setup.

Because it sits at a lower height, it is incredibly easy to maintain and provides precise detection that focuses on the ground level where intruders are most likely to move. It is the gold standard for homeowners who want professional perimeter security without the hassle of false alerts from pets or garden plants.

Pro Tip: The detection range can be masked using the included templates if you need to avoid picking up movement from a nearby street or a neighbor’s property.
