Welit IR W1120 Wired Sensor Security System

Description

IR W1120 is a wall mount infrared motion sensor. It provides the perfect technical line-up for reliably watching over large-sized building fronts, areas as large as 200 m2 with exceptional precision. A multi-lens system provides the coverage angle of 120 with an angle of aperture of 90 and maximum reach of 15 meters. It has highly sensitive pyro-sensor operating as the heart of its system. It detects heat radiated from a body. Segmented lenses divide the whole detection area into passive and active zones. When any warm object like human body moves between the zones, it is detected as a change in voltage by the pyro-sensor. When it detects such movement, it triggers the switching mechanism to operate the connected load.
