Model 420 Passive Infrared Intrusion Sensor

Model 420 Passive Infrared (PIR) Intrusion Sensor is an advanced stand-alone sensor designed for specialized outdoor intrusion detection applications. A four-zone, continuous and gap-free curtain sensing pattern detects intruders by sensing temperature (heat radiation) difference between the background scene and intruder. The pattern includes long, medium and short range detection segments, plus a controllable Creep Field that protects the area surrounding  the mounting pole, which eliminates the detection ‘dead zone’ characteristic of traditional PIR sensors.

Minimal clear zone requirements for the Model 420’s detection pattern make this sensor ideal for intrusion detection in very narrow corridors.
