The FIBARO Door / Window Sensor is compact and simplistic, thanks to a selection of 7 different colours it can adapt to its surroundings with ease. No unsightly cables to run along door frames or window cubbies, the proximity sensor is battery powered and optimised for extended periods of use. The sensor monitors doors and windows or any hinged portal you can think to deploy it, match it to an alarm to deter intruders or log access to a restricted room. Impress visitors by activating scenes as you open the door, raise the lights and open the blinds while a subtle symphony swell fills the room.
