HF HB1360 is a high frequency high bay ceiling mount motion sensor. It is specially designed to install at large heights, up to 10 meters. It has cutting-edge HF-sensor operating as the heart of its system. It is a trans-receiver of high frequency microwave signals. First it emits the signals which are reflected back from the surrounding objects, like wall, furniture or floor. It receives the echo of the reflected signals. Whenever there is any change in the received echo that means the movement is detected inside the detection area and the sensor triggers the switching mechanism. This detection technique is irrespective of ambient temperature and hence it gives the seamless performance over the various climate conditions. Because of its HF-sensor technology, it can detect motion through doors, glass partitions, thin walls, wooden or stud walls, etc.
