Dual Technology PIR/Ultrasonic Occupancy Sensor Wall Switch For Home Security

Model: MWOS Description:Single Pole OCC/VAC(2 IN 1) PIR/Ultrasonic Dual Technology Sensor Switch Neutral Wire Required.


Dual Technology PIR/Ultrasonic Occupancy Sensor Wall Switch For Home Security


Ultrasonic motion detection gives maximum sensitivity yet can be vulnerable to false triggering from air conditioning current, corridor activity, and movement of inanimate objects. Infrared motion sensing gives immunity to false triggering, but lacks sensitivity at greater distances. Our multi-technology sensors combine the benefits of both infrared and ultrasonic technologies for unrivaled performance and reliability.
