For example, they sell passive and decorator infrared sensors that use a unique Fresnel lenses that divide coverage into zones in order to enhance movement detection. When movement disrupts the infrared background, the sensor turns on the light. In addition, they offer decorator passive infrared wall switch vacancy sensors to detect when a space becomes unoccupied, and turn off lights in response. These products come with options like single- or dual-relay, and ultrasonic or dual-technology.
