The Ajax MotionProtect Plus is a wireless motion detector featuring an additional microwave sensor specifically designed for challenging indoor environments such as rooms with air conditioners and fireplaces. The dual-sensor technology, combining a PIR sensor with a 24 GHz microwave sensor reliably detects human presence by temperature difference while intelligently filtering out draughts, curtain movement, light flickering, and reflections. This makes it the ideal choice for spaces where standard detectors might generate false alarms. Model - BD422W
