Function

The PIR20 passive infrared scanner enables problem-free detection of people. It detects movement as soon as the temperature differential between an object and its environment is greater than ± 0.5°C. The detection range can be accurately set by means of zoom adjustment and lens apertures. The PIR20 detects people approaching as a door.
