Detailed specifications and benefits
This detector is engineered with practical specifications that address the most common challenges of perimeter security:
- Detection range:Adjustable, typically 8–12 m. The adjustable range allows the installer to tailor coverage to specific windows, doors or narrow corridors without overreaching into unwanted areas.
- Beam pattern:Horizontal angle ≈ 8° for a tight curtain beam; vertical coverage up to 85° depending on mounting height. The curtain beam is ideal for protecting linear approaches while avoiding wide‑area nuisance triggers.
- Motion speed:Detects motion between 0.3–2.0 m/s, making it sensitive to human intruders but less likely to respond to small, slow movements from vegetation.
- Sensors:2× PIR + 1× 24 GHz K‑band microwave. Correlation between PIR and microwave reduces false alarms from pets, thermal noise, sunlight reflections or moving foliage.
- Protocols:Jeweller for encrypted alarm/events reporting and Wings for OTA firmware updates. The two‑way communication ensures reliable event delivery and remote management.
- Radio range:Up to ~1,700 m open space (region dependent), sufficient for most residential and commercial installations when used with a compatible hub or transceiver.
- Power:2× CR123A (pre‑installed) delivering a nominal voltage of ≈ 6 V and up to ~3 years typical battery life under normal reporting/loading conditions. Long battery life reduces maintenance frequency for installers and end users.
- Ingress protection:IP55 rating with supplied hood—designed for outdoor exposure to rain and dust while preventing false alarms from environmental conditions.
- Operating range:−25 °C to +60 °C and up to 95% non‑condensing humidity, making it suitable for a broad range of climates.
- Form factor:Compact dimensions (141 × 60 × 72 mm without hood; ≈ 155 × 77 × 85 mm with hood) and lightweight design (~223 g) simplify mounting and concealment on facades, frames or posts.
- Anti‑masking:Built‑in anti‑masking meets Grade 2 requirements, detecting attempts to block or obscure the detector’s field of view.
- Tamper protection:Anti‑tamper and accelerometer alerts notify central systems if the device is moved, detached or interfered with.
- Installation kit included:SmartBracket, angle mount, hood and quick start guide enable faster, repeatable installations and allow installers to set pet‑immune mode by mounting at the recommended height (around 1 m).
Use cases and scenarios where the detector excels
The Curtain Outdoor Jeweller is intentionally designed for linear, narrow‑sector protection. Typical scenarios where it outperforms general‑purpose detectors include:
Windows and balcony doors are common intrusion points. The narrow curtain beam can be aimed along the window frame or balcony edge to detect an intruder attempting to enter through a window without covering the entire room, reducing false alarms from occupants inside.
Mounted on a fence post or wall, the detector forms a precise detection corridor that can identify anyone moving along a property line or alley while ignoring movement beyond the protected strip (trees, neighbors’ activity).
For garages, side doors and delivery entrances, the curtain beam covers the access point while leaving wider areas unaffected. This is useful where motion inside a wider zone would be undesirable or produce nuisance alarms.
Retail storefronts, loading bays and equipment enclosures benefit from targeted perimeter sensors. The dual‑tech approach reduces false alarms that could come from vehicle headlights, heat sources or small animals.
Comparisons with similar products and alternative approaches
When choosing a perimeter sensor, it helps to understand how curtain detectors compare to other technologies:
- False alarm resistance:The addition of a microwave channel provides correlation processing, which sharply reduces false positives from thermal noise or moving vegetation compared with PIR‑only units.
- Installation flexibility:Dual‑tech models are generally more forgiving in outdoor installations and challenging light/temperature conditions.
- Precision:Curtain detectors provide linear, focused protection that avoids triggering on peripheral activity. Wide‑area sensors are better for broad coverage but can be prone to nuisance alarms in cluttered environments.
- Use case:Choose curtain detectors for windows, doorways and fences; choose wide‑area detectors for open yards or general motion detection.
Several manufacturers offer curtain‑style and perimeter sensors. Typical distinctions to consider are protocol/ecosystem (Ajax’s Jeweller/Wings vs proprietary wired or other wireless systems), ease of integration, radio range, anti‑masking capability and weatherproofing. Curtain Outdoor Jeweller stands out for its combination of long radio range, OTA update support, compact form factor and an included mounting kit—features that make it more convenient for both DIY installers and professional integrators when used with an Ajax hub ecosystem.
Practical installation advice and limitations
To get the best performance:
- Mount at the recommended height (around 1 m) for pet‑immune configurations; check vertical coverage relative to the protected zone.
- Use the supplied hood and SmartBracket to prevent direct rain and to stabilize the beam alignment.
- Aim the curtain along the edge to be protected, avoiding pointing the beam at busy roads, reflective surfaces or dense foliage that could create high background noise.
- Verify radio link quality with the hub and keep firmware up to date via Wings to maintain performance and security.
Limitations to note: curtain detectors are specialized tools—not direct replacements for full‑area monitoring. They should be used as part of a layered security concept (locks, cameras, wide‑area sensors, alarm monitoring).
Customer feedback and installer notes
There are no specific verified customer quotes included with this product brief. However, installer feedback and pre‑deployment reports for dual‑tech curtain detectors typically emphasize:
- Reliable reduction in false alarms when compared to PIR‑only options, especially in gardens and along fences.
- Fast setup and predictable alignment using the included bracket and hood.
- Long battery life that keeps maintenance cycles infrequent, a key benefit for large‑scale installations.
- Positive response to anti‑masking and tamper features for higher‑security applications.
When considering procurement for a larger project, many installers recommend trialing a small number of detectors in representative locations to fine‑tune mounting height and beam angles before rolling out site‑wide.
