Curtain Outdoor Mini Jeweller: precision protection for perimeter openings

Precision is necessary for securing a property's perimeter, particularly at small entry points like windows, doors, and walkways. A wireless motion detector of the curtain type, the Curtain Outdoor Mini Jeweller was created especially for these difficult situations. The small gadget, designed for both indoor and outdoor use, detects intruders while permitting unrestricted movement within the protected area, creating an imperceptible veil of safety.

This curtain detector ensures dependable performance across a variety of environmental conditions by combining cutting-edge dual-motion detection technology with a robust anti-masking mechanism. Whether protecting a private residence, a garage entrance, or a commercial storefront, the Curtain Outdoor Mini Jeweller offers a perfect balance of security, autonomy, and ease of use.

Dual technology for false alarm immunity

One of the standout features of the Curtain Outdoor Mini Jeweller is its two-stage motion detection system. To prevent false alarms — a common issue with outdoor sensors — the device uses a sophisticated combination of thermal and radio-frequency analysis.

• PIR sensor. The primary stage involves a passive infrared sensor that detects moving objects with temperatures different from the environment.
• Microwave sensor (K-band). Upon detecting motion, the device instantly performs a radio-frequency scan. This secondary check filters out thermal interference caused by air flows, swaying bushes, or exhaust fans.

This "SmartDetect" algorithm greatly reduces false positives caused by environmental factors by ensuring the alarm is triggered only when both sensors confirm an intruder. Additionally, the detector features temperature correction, ensuring precise detection even when the ambient temperature approaches body temperature.

Narrow beam for targeted coverage

Unlike standard motion detectors that cover wide areas, the Curtain Outdoor Mini Jeweller features a specialized optical system. It projects a narrow horizontal detection angle of 15° and a wide vertical angle of 100°. This creates a "curtain" effect, ideal for securing:

• windows and door frames
• garage doors
• fence lines and gates
• narrow pathways between buildings
• arches and corridors

With a detection range of up to 5 meters, it effectively guards these specific entry points without interfering with activity just outside the detection zone.

Advanced anti-masking and sabotage protection

Outdoor detectors are often targets for sabotage. The Curtain Outdoor Mini Jeweller features a high-grade anti-masking system. It can detect attempts to block the lens with obstacles like tape, paint, or fabric at a distance of up to 5 cm. If masking is detected, the system immediately notifies the security company and the users.

Additional protection measures include:

• Tamper alert: a built-in tamper button triggers an alarm if the device is detached from its SmartBracket mounting panel or torn from the surface.
• Accelerometer: an optional setting that triggers an alarm when the device is moved or rotated.
• Data encryption: all communicated data is protected by block encryption with a dynamic key to prevent spoofing and data theft.

Reliable wireless communication

The detector integrates seamlessly into the Ajax ecosystem using two proprietary secure radio protocols:

1. Jeweller: transmits alarms and events instantly.
2. Wings: dedicated to transmitting firmware updates and diagnostic data.

This dual-protocol approach ensures stable communication with the hub at distances of up to 1,700 meters in open space. The device also features a regular polling interval (default 36 seconds) to ensure the hub is always aware of the detector's status.

Energy efficiency and autonomy

Designed for long-term operation with minimal maintenance, the Curtain Outdoor Mini Jeweller comes with pre-installed batteries that provide up to 3 years of autonomous operation. The device also includes a "Notify on risk of fast battery discharge" setting. This intelligent feature analyzes triggering frequency and alerts users if incorrect installation (e.g., facing a busy street) is causing excessive power consumption, allowing for timely adjustments.

Pet immunity and flexible installation

The detector is designed to coexist with pets. When installed at the recommended height of 1 meter and set to "Pet" mode via the enclosure's slider, the device ignores animals up to 70 cm tall. This makes it an excellent choice for homeowners with dogs or cats who need to secure their perimeter without restricting their pets' movement.

Professional installation and configuration

The Curtain Outdoor Mini Jeweller is designed for professional installation. It includes a SmartBracket panel for quick mounting without disassembling the enclosure. Configuration is handled entirely remotely via the Ajax app, where installers can adjust sensitivity, manage detection zones, and run signal strength tests.

Conclusion

By choosing the Curtain Outdoor Mini Jeweller, you are investing in a high-precision instrument that secures the most vulnerable points of your property with advanced technology and uncompromising reliability. This intelligent curtain detector seamlessly integrates into your existing Ajax ecosystem, providing peace of mind whether you are at home or away.
