Ajax MotionProtect Curtain Black Wireless Indoor Curtain Motion Detector

Ajax MotionProtect Curtain Black - Wireless Indoor Curtain Motion Detector

The Ajax MotionProtect Curtain is a wireless PIR motion sensor purpose-built to guard narrow entry points such as windows, doorways and hallways. Rather than covering a wide room, it projects a slim, curtain-like detection beam that is ideal for perimeter-style protection while still allowing free movement elsewhere in the property. It communicates with an Ajax hub over the long-range, encrypted Jeweller radio protocol, making it a reliable addition to any Ajax wireless alarm system.

Key Features

• Dual-sensor curtain detection: Two infrared sensors combined with a multifaceted mirror give the detector twice the situational data compared with a standard single-PIR sensor, improving accuracy along the detection line.
• Narrow, adjustable beam: Motion detection range is adjustable from 6 to 15 metres, with a horizontal viewing angle of 6° and a vertical angle of 90° for precisely focused coverage.
• Long-range Jeweller connectivity: Maximum motion detection distance is 15 m, connecting to a hub through the Jeweller secure protocol with wireless coverage of up to 1,700 m line-of-sight.
• Encrypted two-way communication: The sensor supports communication with the hub at a distance of up to 1700 meters without obstacles, with information protected by encryption through the Jeweller two-way radio protocol.
• Anti-jamming protection: When jamming is attempted, or in the event of interference, the security system switches to a free radiofrequency and notifies users and the security company.
• False-alarm reduction: A Correlation Signal Processing function can be enabled so the detector only sends an alarm state if an identical motion signal is registered by both IR sensors.
• Long battery life: The pre-installed battery ensures up to 3 years of autonomous operation.
• Tamper protection: A tamper button triggers when someone tries to tear off the detector from the surface or remove it from the mount.
• Cold-tolerant operation: The curtain detector will continue to operate even if the temperature drops to -10°C, suiting garages and unheated spaces.

Reliable Perimeter Security for Homes and Businesses

MotionProtect Curtain Black is best suited to guarding a specific opening rather than an entire room. Mounted beside a window, doorway or hallway, it lets occupants move freely indoors while still detecting anyone attempting to enter through that protected line. When installed correctly, it keeps private property safe while ignoring pet movement, and in a garage setting it prevents burglars from getting through the door undetected, continuing to operate even in cold conditions. It also suits retail, gallery or office environments where a narrow, invisible detection line along a specific boundary is preferable to full-room coverage.

Frequently Asked Questions

Does MotionProtect Curtain work with any Ajax hub?
Yes. It integrates into Ajax security systems, connecting to a hub through the Jeweller secure protocol, so it can be added to any compatible Ajax hub-based system.

Can it be used outdoors?
No. The device is developed only for indoor use, not for installation outside the premises.

How is the detector configured?
An iOS or Android app is used for detector setup, allowing installers to adjust sensitivity, enable Correlation Signal Processing, and pair the device via QR code.
