Ajax MotionProtect Plus White Wireless PIR & Microwave Motion Detector

Ajax MotionProtect Plus White Wireless Motion Detector

The Ajax MotionProtect Plus is a wireless indoor motion sensor that pairs a passive infrared (PIR) detector with a K-band microwave sensor to confirm genuine intrusions and filter out false triggers. Designed for homes, offices and light commercial spaces, it connects to an Ajax hub over the encrypted Jeweller radio protocol and is finished in a sleek white housing that blends with most interior décor.

Key Features

• Dual-technology detection: A PIR sensor detects body-heat movement while the microwave sensor verifies the alarm, reducing false triggers from air conditioners, fireplaces or drafts.
• Long detection range: Covers up to 12 metres with an 88.5° horizontal and 80° vertical viewing angle.
• Pet-immune design: The SmartDetect algorithm ignores animals weighing up to 20 kg and standing up to 50 cm tall, cutting down on nuisance alerts.
• Adjustable sensitivity: Three selectable sensitivity levels let installers balance detection accuracy against false-alarm prevention.
• Long-range wireless link: Communicates with the hub or a range extender over distances of up to roughly 1,200 metres in open space via the secure two-way Jeweller protocol.
• Tamper and sabotage protection: Alerts are triggered if the enclosure is opened, the unit is removed from its mount, or the radio channel is jammed.
• Long battery life: Runs on a single pre-installed CR123A battery for up to 5 years, with early low-battery warnings sent through the Ajax app.
• Fast, tool-free setup: The included SmartBracket mounting panel and QR-code pairing let installers mount and add the device to a system in minutes, with remote configuration afterwards.

Where to Use It

MotionProtect Plus is best suited to indoor rooms, hallways, offices and retail areas where reliable intrusion detection is needed without false alarms caused by heating, cooling or pets. Mounting it at the recommended height of around 2.4 metres, with the lens facing across likely intrusion paths, gives the most consistent coverage. It integrates into a wider Ajax security ecosystem alongside hubs, sirens, keypads and other sensors managed from a single app.

Frequently Asked Questions

Does it work with pets in the house? Yes, its detection algorithm is designed to ignore animals up to 20 kg in weight and 50 cm in height, so cats and most dogs won't trigger false alarms.

How long does the battery last? The pre-installed CR123A battery is rated for up to 5 years of typical use, and the Ajax app provides advance low-battery notifications.

Can it be installed outdoors? No, MotionProtect Plus is designed for indoor use only; outdoor installation can cause false alarms or device damage.
