Adaptive Dual Technology combines Ultrasonic and Passive Infrared technology, minimizing the risk of lights turning ON when the space is unoccupied. Once occupancy is detected by both technologies within the space lights are turned ON, only one technology is necessary to keep the lights ON. Adaptive technology provides better control. Hubbells patented breakthrough in advanced control feature smart microprocessors constantly monitoring the controlled area and adjust the sensitivity and timer based on environmental history. The optimum choice when performance is paramount.
