Curtain Outdoor Mini Jeweller

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

The first line of defence

Curtain Outdoor Mini Jeweller is a curtain-type motion detector with dual motion detection technology and an anti-masking system. This product is engineered to cover windows, doors, narrow passages, and other entry points along the perimeter. Break-in attempts are exposed early — before they leave a scratch. While the device blends in, its effectiveness stands out thanks to near-zero false alarms, no blind zones, and exceptional autonomy.

Designed for tight spaces

Curtain Outdoor Mini Jeweller is a practical solution for spotting intruders early. It's ideal when an opening detector can't be installed — for example, on the window frames of a historic building. Horizontal, vertical, or angled mounting allows flexible placement options, making it easy to secure compact areas and prevent unwanted access.

Two detection modes

Curtain Outdoor Mini Jeweller has Main and Pet modes activated via the slide switch on the enclosure. In the Main mode, an alarm is triggered whenever the device detects movement.

In the Pet mode, the detector ignores movement from animals of up to 70 cm tall.

Near-zero false alarms

PIR sensors
A PIR sensor detects movement by analyzing changes in temperature within the device’s field of view. In a split second, the sensor triggers a proprietary software algorithm to check the collected data and determines whether the alarm is real.

K-band microwave sensor
The K-band microwave sensor verifies alarms triggered by PIR sensors. It performs a radio-wave scan of an area to minimize false alarms triggered by thermal interferences. Unlike traditional X-band sensors, the K-band sensor offers superior precision and energy efficiency, with significantly fewer false alarms and hardly noticeable impact on the battery life. Additionally, the sensor is completely safe and poses no threat to health.

Thermal interference filter
When the system is in armed mode, the detector constantly analyzes the thermal diagram from the PIR sensors, including the IR radiation intensity, thermal spot size, movement speed, time spent in the detection zone, and other parameters. The SmartDetect software algorithm identifies false alarm markers instantly and with high accuracy. As a result, the device accurately responds to human movement without false alarms.

Temperature compensation
Temperature compensation is a software mechanism that ensures thermal diagram contrast even if the ambient temperature is close to the temperature of a human body. With each ambient temperature measurement, the detector corrects the PIR sensors data according to the coefficient table stored in its memory. The device is effective throughout the entire operating temperature range.

Sensitivity level
Curtain Outdoor Jeweller has in-app sensitivity settings. Low sensitivity makes the detector less likely to respond to interferences, while high sensitivity ensures an alarm is raised in case of any movement in the detection zone. Set up the needed sensitivity level to avoid costly patrol dispatches to false alarms.

Professional installation
With proper installation, the detector operates with high accuracy and reliably detects threats with minimum false alarms. Pet immunity is ensured by the hardware switch and correct mounting. On top of that, Ajax apps provide remote control, configuration, and adjustable sensitivity levels.

Built to last

The device is wireless and easy to install. It runs on two pre-installed replaceable batteries, each tested before installation. The batteries provide up to three years of operation, and their status is always available in the app. PRO users and monitoring companies receive low-charge alerts months in advance — no need to rush replacements at the last minute.

• Every single battery tested during production
• Up to 3 years of operation on pre-installed batteries
• Early low battery notifications

Unique wireless technologies

Ajax system uses secure two-way radio communication based on Jeweller and Wings proprietary protocols. Radio protocols operate in parallel and focus on their own functions, ensuring instant data delivery even in case of communication interruptions or weak signal.

• Up to 1,700 m of radio communication with a hub or range extender2
• Encrypted two-way radio communication
• Notifications of jamming and connection loss
• Over-the-air firmware updates

System supervision

All Ajax devices perform automatic self-diagnosis and report their states to a hub. Essential parameters, including tamper, communication, power supply, and sensor statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for alarm receiving centers (ARCs), security companies, and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.

• Automatic device self-diagnosis with status report
• Regular polling to display the current device state on apps
• Instant maintenance notifications

Sabotage resistance

Tamper alarm
The enclosure is equipped with a tamper button, which notifies a security company and users once the detector is dismantled from the mounting panel.

Accelerometer
When enabled, a built-in accelerometer alerts about sabotage. Sirens added to the system are activated when Curtain Outdoor Jeweller moves. The feature is crucial if a third-party mount is used. The accelerometer can detect if it is broken or if there are interferences with the detector’s field of view.

Anti-masking system
The device detects masking caused by obstacles at a distance of up to 5 cm from the lens depending on the masking method used. The system notifies users and the ARC of these attempts to interfere with the detector’s operation.

Device authentication against spoofing
The hub checks the device's unique parameters for authentication during each communication session. If any parameter fails the check, the hub ignores device commands.

Data encryption
All data the system stores and transmits is protected by block encryption featuring a dynamic key. This encryption deters intentional sabotage attempts on the detector.

Regular polling
The device regularly exchanges data with the hub. The system controls each device state and reports if there is a malfunction.

Data-rich notifications
The Ajax system instantly notifies of alarms and events with informative notifications: security companies and users know exactly which device triggered, when and where it happened.

Connection loss detection
With minimal polling interval settings (3 data packages in 12 seconds), it takes 36 seconds to identify communication loss and notify the security company and users of the incident.

Fast mounting, seamless configuration

Curtain Outdoor Mini Jeweller is ready to operate straight out of the box. There are three options for installing the detector: using the SmartBracket mounting panel, an angle mount, or a third-party mount. There is also an option to protect masking sensors from rain and snow with the hood. Ajax apps help quickly make the device a part of the system: simply pair the device with the hub by scanning a QR code. The detector can always be reconfigured remotely without the need for on-site visits.
