Renkforce 1362991 Surface-mount, Structure, Wall HF motion detector 180 ° Relay White IP44

The detection works through the high-frequency technology even through doors, glass panels or thin walls. Depending on the nature of the obstacles, the signals are weakened more or less. The motion detector transmits high-frequency signals similar to a radar from the surfaces within the detection range which are reflected back. These signals are evaluated by the integrated electronics. If these signals change, e.g. by a movement (person, animal or object), the detector is triggered.
