Product overview

Passive infrared (PIR) motion sensor technology provides one of the most reliable and cost effective methods for protecting spaces in homes, offices, or industrial facilities. PIR motion sensors sense temperature contrasts between a relatively stable background and hotter or colder objects moving across their fields of view. The sensors emit no energy of their own, they merely see infrared images.

RCR sensors

The PrecisionLine dual technology sensors combine range-controlled radar (RCR) technology with a passive infrared (PIR) system. This combination increases false alarm immunity by allowing them to sense human-sized objects within a specified range. Both the RCR and the PIR system must be triggered to set off an alarm, unless in stealth mode (radar only). An internal jumper allows you to disable the PIR and use the radar-only stealth mode to detect intruders faster. The stealth mode can also be used for covert installations (mounted behind walls or drop-tile ceilings).
