It is a passive infrared curtain sensor designed to protect the frames thanks to its small size, detecting transverse movements. Its ability to self compensate for sudden changes in temperature make it suitable for installation even in critical situations, in fact, the stability of the infrared makes it immune to drafts for outdoor use, while avoiding any direct exposure to atmospheric agents ( rain and sunlight). The sensor creates a curtain barrier of very small size (about 7 °) and has a range of up to 8 meters
