Ajax MotionProtect Plus Black Wireless PIR & Microwave Motion Detector

Ajax MotionProtect Plus (Black) - Dual-Technology 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. Built on Ajax's encrypted Jeweller radio protocol, it connects to any Ajax hub for fast, reliable alarm reporting while remaining easy to install and virtually maintenance-free thanks to its long-life battery. The sleek black housing suits modern interiors in homes, offices, retail spaces and warehouses.

Key Features

• Dual-sensor verification: The PIR sensor detects human-like heat signatures, while the microwave sensor performs a secondary RF scan to confirm real movement before an alarm is raised.
• Pet-tolerant detection: The onboard SmartMotion algorithm is designed to disregard the movement of animals under roughly 20 kg, cutting down on nuisance alarms.
• Long detection range: Monitors an area with a radius of up to 12 metres from the mounting point.
• Adjustable sensitivity: Three sensitivity levels let installers tune performance for the specific room and its environment.
• Resilient to thermal interference: Effectively ignores false triggers caused by air conditioning, fireplaces, drafts, and light reflections.
• Encrypted wireless link: Uses Ajax's proprietary Jeweller protocol with a communication range of up to 1,200 metres line-of-sight to the hub.
• Simple, tool-light installation: Mounts on the included SmartBracket panel without needing to open the enclosure, and pairs to the hub instantly via QR code scan.
• Long battery life: Runs on a pre-installed CR123A battery rated for up to five years of typical use.
• Tamper protection: Triggers an alert if the enclosure is opened or the unit is removed from its bracket.

Where It Fits Best

This detector suits any indoor space where reliable intrusion detection with minimal false alarms is a priority, including living rooms, hallways, offices, retail floors and storage areas. Its resistance to thermal interference makes it a strong option for rooms with air conditioners, heaters or large windows, and its pet-tolerant algorithm suits households or premises where small to medium animals are present.

Frequently Asked Questions

Does it work with any Ajax hub? Yes, it connects wirelessly to any Ajax hub using the Jeweller protocol, and can also integrate with select third-party panels via Ajax's uartBridge or ocBridge Plus modules.

Will it false-alarm on my pets? The built-in SmartMotion algorithm is designed to ignore animals under approximately 20 kg when the detector is installed and configured correctly, though placement and sensitivity settings still matter.

Can it be used outdoors? No, this detector is designed strictly for indoor use; Ajax offers a separate MotionProtect Outdoor model for external areas.
