Ajax MotionProtect Plus WH – Wireless PIR + Microwave Motion Detector, 12 m Range

The Ajax MotionProtect Plus WH is a wireless indoor motion detector combining a passive infrared (PIR) sensor with an additional K-band (24 GHz) microwave sensor. Its two-stage detection principle – the PIR detects thermal change first, which the microwave sensor then confirms via radio-frequency scanning – ensures high detection reliability and minimal false alarms in rooms with air conditioners, fireplaces, curtains, glare, or fluctuating lighting. The detector communicates with the Ajax hub via the Jeweller protocol and is suited for residential and commercial wireless security systems.
