ABSTRACT:
A motion sensor incorporates an internal light source, typically a super bright LED and an optical projection system visible to an observer standing in the motion sensor coverage zone(s) to simplify orientation of the sensor on installation. A multi-lens system or an arrangement of small windows in front of the LED projects a visible light pattern that mimics the detection pattern of the motion sensor to an observer standing in the detection zone and looking at the sensor.
