Signal Detection Range Diagram:

The image below is a diagram of the microwave signal sensing range. Detection angle: the detection angle in the direction parallel to the antenna (azimuth) is 72° and the detection angle in the direction perpendicular to the antenna (pitch) is 36°

False Positive Diagram

The image below shows a false alarm when installed near a wall. Microwaves have the ability to penetrate building walls, and when microwaves escaping from the walls affect moving targets outside the fortified area, it can cause false alarms.
When installing this type of probe, the installation site should be carefully selected to avoid false alarms.
