Ajax MotionProtect Curtain White Wireless Indoor Curtain Motion Detector

Ajax MotionProtect Curtain White - Wireless Indoor Curtain Motion Detector

The Ajax MotionProtect Curtain is a wireless PIR motion detector purpose-built to create an invisible detection curtain across windows, doors, hallways and other narrow entry points. Rather than covering an entire room like a standard PIR, its optical design projects a thin vertical beam that can be positioned exactly where an intruder is likely to pass, making it a smart choice for perimeter-style protection inside a home, office, garage or gallery space. Finished in white, it pairs neatly with most interior decors and installs in minutes using the included SmartBracket mount.

Key Features

• Long detection range - picks up movement at distances of up to 15 metres.
• Narrow curtain-style coverage - a 6° horizontal by 90° vertical field of view focuses detection on a specific line rather than an open area.
• Dual IR sensor optics - a multifaceted mirror feeds two infrared sensors simultaneously, helping the detector recognise both slow, creeping movement and fast running intruders.
• Correlation Signal Processing - an optional setting that only triggers an alarm when both IR sensors register the same signal, reducing false alarms.
• Secure Jeweller radio protocol - encrypted two-way communication with the hub, with automatic frequency switching if jamming or interference is detected.
• Long wireless range - communicates with the Ajax hub or a range extender over long line-of-sight distances.
• Long battery life - runs on a pre-installed battery rated for up to three years of use without external power.
• Tamper protection - an integrated tamper switch triggers an alert if the unit is removed from its mount or forced from the wall.
• Fast setup - added to an Ajax system in minutes by scanning the on-device QR code with the Ajax mobile app.

Where to Use It

MotionProtect Curtain is designed for indoor perimeter-style protection rather than open-room coverage. Typical placements include mounting beside a window or French door to detect anyone climbing through, across a hallway leading to a secure area, at the entrance of a garage, or along a gallery wall to trigger an alert if someone reaches toward an exhibit. Because it can be installed upside down to raise its lower detection boundary, it is also a practical option in pet-friendly homes where nuisance alarms from animals need to be minimised.
