Wireless dual-technology curtain motion detector for outdoor and indoor use

Standards and certifications
Curtain Outdoor Jeweller · CO.Y.J. Manufacturer-listed marks; regional and installation conditions apply.
Curtain Outdoor Jeweller creates a narrow motion-detection zone along an approach, facade or opening. Two PIR sensors and K-band microwave verification help distinguish an intrusion from thermal interference. Adjustable range, standard and Pet modes, and anti-masking protection let the installation match the site.

An 8° horizontal field protects a narrow approach along doors, windows or a facade. Set the range using the enclosure slider and matching app settings.
Test the entire intended approach. Avoid passing traffic, vegetation or other objects that should stay outside the protected area.

Use Near or Far settings for standard detection at the recommended 2.4 m height.

Two PIR sensors detect thermal movement in the curtain-shaped zone.

The software checks thermal pattern size, movement and intensity before classifying a trigger.
Two preinstalled CR123A batteries provide up to three years under the specified conditions. The app reports battery status and low-charge warnings.
IP55 enclosure for indoor or outdoor use, −25°C to +60°C. Activity, placement, polling and radio conditions affect battery life.
Jeweller carries alarms, device status and configuration. Wings carries firmware updates on this model; it does not add a camera or photo verification.
Up to 1,700 m in open space. When connected through the original ReX, firmware updates are unavailable because it does not support Wings.

A compatible assigned range extender can connect a detector where the direct hub link is weak. Test the detector-to-extender path and the extender-to-hub path at their installed positions.
A range extender increases coverage, not the hub’s total device capacity. Ethernet on a supported extender is its connection to the hub; the detector itself stays wireless.

The detector reports attempts to block its view, including the masking methods listed in the manual.
Check anti-masking after installation. Fit the hood to protect the masking sensors from precipitation.

An enabled accelerometer reports attempts to shift the mounted device.
Enable and test it when using the relevant alternate mount.

The tamper monitors the mounting panel; the hub also checks connection and device state.
Connection-loss detection depends on polling settings.

Scan the device QR code in the Ajax app, then assign a recognisable name and room. Check compatibility with the hub and any range extender before installation.
