Why Ultrasonic Sensing?

Ultrasonic is quicker to react in stairwell applications without direct line of sight than PIR or microwave technologies—so the light comes on before people are in the area. In addition, its degree of sensitivity prevents false or un-needed “on” states from motion behind walls separate from the stairwell or desired area of detection.
