Spec Data Sheet Button

The Ajax MotionProtect Plus White is a wireless indoor motion detector that detects human presence by temperature difference with background thermal radiation due to the microwave sensor.

Designed for rooms with air conditioners, fireplaces and where there is a likelihood of light flickering, glare and reflections, eliminating false alarms due to draughts or movement of curtains and blinds.

The MotionProtect Plus can operate for up to 5 years from a built-in battery and monitors the area within a 12-meter radius. It ignores animals, while recognizing a human from the first step.

Please note: MotionProtect Plus operates within the Ajax system, connected to the hub via the protected Jeweller protocol.

Compatible with Hub, Hub Plus, Ajax ReX, Ajax ocBridge Plus and Ajax uartBridge.
