Satel MPD-300 motion detector Passive infrared (PIR) sensor Wireless Wall White

Motion detector, whose function is to detect an intruder moving within the system protected area. Owing to its pet immunity, the MPD-300 can provide protection even if small animals, such as small dogs or cats, are moving in its coverage range at the time of supervision. A lithium battery used to power the device ensures many years of work without having to replace it, so the system is as easy to use as the traditional wired solutions.
