Feller Flush-mounted motion detector

PIR motion detector, round, flush-mounted. Maximum 2300 W. Adjustable brightness threshold, sensitivity, and delay time. Detection angle 360°. Pulse function and button input. Detection range radial 10 m / tangential 14 m. Slave input for area expansion. Relevant movements are detected using a PIR sensor. The sensor with PIR technology (PIR stands for passive infrared) responds to minimal local temperature changes, which it perceives as infrared light with a specific wavelength. This allows it to register people, vehicles, and animals entering the detection area while ignoring swirling leaves or moving branches. It also does not take into account fluctuations in general temperature, such as those caused by sunlight. In this way, the motion detector avoids false triggers and ensures reliable detection of relevant objects.
