Ajax Curtain Outdoor Jeweller White Wireless Perimeter Motion Detector

Ajax Curtain Outdoor Jeweller (White) - Wireless Perimeter Motion Detector

The Ajax Curtain Outdoor Jeweller is a wireless, dual-technology motion sensor purpose-built to guard the outer perimeter of a property. Rather than covering a wide area, it projects a narrow, curtain-shaped detection beam along a fence line, facade, window, or gateway, giving early warning of an approaching intruder while letting people move freely inside the protected zone. Combining two PIR sensors with a K-band microwave sensor, it delivers highly accurate alarm decisions with a very low rate of false triggers, making it a reliable first line of defence for homes, offices, warehouses, and other commercial sites protected by an Ajax security system.

Key Features

• Dual-technology detection: Two independent PIR sensors work alongside a K-band microwave sensor, with an alarm only raised when both technologies confirm genuine motion.
• Long, narrow detection zone: The optical system watches a slim sector reaching up to roughly 12 metres, ideal for fence lines, facades, and pathways rather than open areas.
• Smart false-alarm filtering: On-board digital algorithms analyse the motion signal in real time to rule out animals, wind-blown plants, and thermal interference.
• Adjustable sensitivity and range: Detection distance and sensitivity can be tuned on-site or remotely via the Ajax app to suit the specific installation.
• Pet immunity mode: A dedicated operating mode ignores the movement of smaller animals to reduce nuisance alerts.
• Weatherproof housing: Rated for outdoor exposure, the enclosure is built to withstand rain, dust, and a wide temperature range.
• Long battery life: Runs on pre-installed batteries for extended autonomous operation without frequent replacement.
• Secure wireless connection: Communicates with the Ajax hub using the encrypted Jeweller radio protocol for tamper-resistant, long-range performance.
• Flexible mounting: Can be installed vertically or horizontally, adapting to different structural layouts and mounting heights.

Ideal Applications

This detector is best suited to protecting the approach to a building rather than the interior. Typical placements include along boundary fences, beside garden walls, across driveways and walkways, under windows, and near entry gates. Because its beam is narrow and directional, it is commonly paired with other Ajax intrusion devices to create a layered perimeter defence, triggering an early alert before a would-be intruder reaches the building itself.

Frequently Asked Questions

Can this detector be used indoors as well as outdoors?
Yes. While designed primarily for outdoor perimeter protection, the dual-technology curtain detector can also be installed indoors where a narrow, long-range detection zone is needed.

Will pets or small animals set off false alarms?
The detector includes a pet immunity mode that filters out movement from smaller animals, significantly reducing unwanted alerts in gardens and yards.

Does it need a wired power connection?
No. It operates wirelessly on pre-installed batteries and communicates with the Ajax hub via the encrypted Jeweller radio protocol, so no cabling is required at the detector.
