Curtain Outdoor Mini Jeweller is a wireless curtain-type motion detector with dual motion detection technology and an anti-masking system. The device is designed for outdoor and indoor use. It features a narrow horizontal detection angle of 15° and a wide vertical detection angle of 100°. This allows the detector to cover windows, doors, narrow pathways, and other entry points along the perimeter. The device detects motion at a distance of up to 16.4 ft.
Curtain Outdoor Mini Jeweller communicates with the hub using two secure protocols. The detector uses Jeweller to transmit alarms and events and Wings to update the firmware. The communication range in an open space is up to 5,550 ft. Pre-installed batteries ensure up to 3 years of autonomous operation.

Compatible hubs and range extenders
The device requires a compatible Ajax hub with OS Malevich 2.34 or later to operate.
Operating principle
A PIR sensor of Curtain Outdoor Mini Jeweller registers intrusion upon detecting moving objects with a temperature different from the ambient temperature.
When the device detects motion, it additionally performs a radio frequency (RF) scan with a built-in K-band microwave sensor. It helps to eliminate false alarms caused by thermal interference: air flows, fans, air conditioners, etc.
In case of an alarm, a detector instantly sends it to the hub. Therefore, the hub activates the sirens connected to the system, runs the scenarios, and notifies users and the security company. All Curtain Outdoor Mini Jeweller alarms and events are recorded in the event feed of Ajax apps.
Users and the monitoring company know exactly where motion is detected. The notifications contain the name of a space (the name of a guarded facility), the device name, and the virtual room to which the detector is assigned.
The detector doesn’t switch to the armed mode instantly. The switching time depends on two factors: the exit delay (specified in the detector settings) and the hub–detector polling interval (Jeweller or Jeweller/Fibra settings; the default value is 36 s). In the first case, the delay is set by an admin or a PRO user with admin rights. In the second case, the delay occurs because it takes one polling interval for the hub to notify the detector about switching to the armed mode.
Protection against false alarms
Curtain Outdoor Mini Jeweller uses the SmartDetect algorithm to protect against false alarms. This algorithm allows the detector to analyze the thermal diagram read by the sensor: the intensity of infrared radiation, the size of the heat spot, the time spent in the detection area, and other parameters.
After this stage, an additional RF scan of the facility is run using the built-in K-band microwave sensor. Depending on the result, the alarm is activated or not.
Pet immunity
When properly installed and configured, Curtain Outdoor Mini Jeweller will not respond to pets up to 39″ in height. We recommend installing the detector at a height of 3.3 ft, adjusting the slider on the detector enclosure to the Pet position.
Follow our recommendations to install and configure the detector.
Temperature compensation
Due to temperature compensation, the detector responds to movements, even if the indoor or outdoor temperature is close to the human body temperature. Read more about temperature compensation in the article.
Anti-masking system
Masking is an attempt to block the view of the detector. Curtain Outdoor Mini Jeweller detects an obstacle in front of the lens at a distance of up to 2″. The maximum distance depends on the obstacle material.
The system notifies users and the security company’s monitoring station about masking. The maximum masking detection time is 180 s (depending on the obstacle type and the distance).
If the Anti-masking feature is enabled, it is always active and works regardless of the security mode.
Jeweller and Wings data transfer protocols
Jeweller and Wings are wireless data transfer protocols that provide fast and reliable two-way communication between the hub and devices. The detector uses Jeweller to transmit alarms and events and Wings to update the firmware.
Sending events to the monitoring station
The Ajax system can transmit alarms to the Ajax PRO Desktop monitoring app, as well as to the central monitoring station (CMS), in formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.
Curtain Outdoor Mini Jeweller can transmit the following events:
- Motion alarm.
- Masking.
- Alert if moved.
- Tamper alarm/recovery.
- Loss/restoration of connection with the hub.
- Permanent deactivation/activation of the device.
- One-time deactivation/activation of the device.
When an alarm is received, the operator at the security company’s monitoring station knows what happened and precisely where to dispatch a rapid response unit. The addressability of Ajax devices allows sending events to Ajax PRO Desktop or the CMS, including the device’s type and name, security group, and virtual room. Note that the list of transmitted parameters may vary depending on the CMS type and the selected communication protocol for the monitoring station.
Protection against faster battery discharging
To prevent rapid battery discharge, Curtain Outdoor Mini Jeweller has the Notify on risk of fast battery discharge setting. Once the system detects that the device is installed incorrectly, system users will receive notifications in Ajax apps, and similar information will be displayed in the device states.
The device sensors can be triggered by different objects or obstacles, which the device filters out as unconfirmed alarms. Also, the device requires more power to process each triggering. As a result, when the number of such triggerings gets too high, the system will notify about increased power consumption and the risk of fast battery discharge.
Enable the Notify on risk of fast battery discharge feature in the device settings to save the battery charge.
Consider changing the device placement if you receive a notification about incorrect installation.
Adding to the system
Before adding a device
- Install the Ajax app.
- Log in to your account or create a new one.
- Select a space or create a new one.
- Add at least one virtual room.
- Add a compatible hub to the space. Ensure the hub is switched on and has internet access via Ethernet, Wi-Fi, and/or mobile network.
- Ensure the space is disarmed, and the hub is not starting an update by checking statuses in the Ajax app.
Only a PRO or a space admin with the rights to configure the system can add a device to the hub.
Adding to the hub
- Open the Ajax app. Select a space where you want to add the detector.
- Go to the Devices
tab and click Add Device.
- Name the device, scan, or type in the QR code (placed on the detector and the package box), and select a room and a group (if Group mode is enabled).
- Click Add — the countdown will begin.
- Switch on the device by holding the power button for 3 seconds.
Once added to the hub, the detector will appear in the list of hub devices in the Ajax app. The device status update frequency in the list depends on the Jeweller or Jeweller/Fibra settings, with the default value of 36 s.
If the connection fails, try again in 5 seconds. If the maximum number of devices is added to the hub, you will be notified when trying to add a new one.
Curtain Outdoor Mini Jeweller works with only one hub. Once the device is connected to a new hub, it stops sending events to the old one. Adding the detector to a new hub does not automatically remove it from the device list of the old hub. This must be done using the Ajax app.

Functionality testing
The Ajax system offers several types of tests to help choose the correct installation place for the devices. Testing does not start immediately. However, the waiting time does not exceed the duration of one hub–device polling interval. The polling interval can be checked and configured in hub settings (Hub → Settings → Jeweller or Jeweller/Fibra).
To run the test in the Ajax app:
- Select a space.
- Go to the Devices
tab.
- Select Curtain Outdoor Mini Jeweller from the list.
- Go to Settings
.
- Select a test:
- Run the test.
Device placement
Curtain Outdoor Mini Jeweller is suitable for protecting windows, doors, narrow pathways, and other perimeter openings. It allows you to secure the perimeter, leaving space for free movement inside. The detector can be installed both outdoors and indoors.
Curtain Outdoor Mini Jeweller can protect:
- Front doors.
- Windows.
- Gates.
- Fences.
- Arches and other places where you need to protect the perimeter or passage.
The detector should be placed at a height of 3.3 ft on a side surface or up to 16.4 ft on the ceiling, depending on the protected area size. For the Pet immunity feature to work properly, the detector should be installed at a height of 3.3 ft on a side surface.
If you install the detector at a height other than the recommended one, ensure there are no false alarms caused by pets, the device detects people’s motion, and the detection zone meets your needs.
If the surface is not flat, the installation height is calculated from the highest point of the area to be protected.
The detector should be installed on a flat, stable surface, for example, on the wall of a house or a solid fence. Installing the detector on a shaky (unstable) surface will result in false alarms. The detector enclosure must be placed perpendicular or parallel to the ground level, and the intended path of the intruder must be perpendicular or parallel to the axis of the detector’s lens.
When choosing where to place Curtain Outdoor Mini Jeweller, consider the parameters that affect its operation:
- Motion detection zone.
- Jeweller and Wings signal strength.
- Distance between the detector and the hub or range extender.
- Presence of obstacles between devices that may affect the radio signal, such as walls, inter-floor ceilings, or large objects located on the premises.
- Presence of bushes, trees, air conditioners, glass, and other structures that may block the detector’s view.
- Presence of water reservoirs or pools in the detection area. They may cause false alarms.
Consider the recommendations for detector placement when developing a security system project for the facility. The security system must be designed and installed by specialists. The list of recommended Ajax partners is available here.
Signal strength
The signal strength is determined by the number of undelivered or corrupted data packages over a certain period of time. The icon in the Devices
tab in Ajax apps indicates the signal strength:
- three bars — excellent signal strength;
- two bars — good signal strength;
- one bar — low signal strength, stable operation is not guaranteed;
- crossed out icon — no signal.
Check the Jeweller and Wings signal strength before final installation. With a signal strength of one or zero bars, we do not guarantee the device will operate stably. Consider relocating the device, as adjusting its position even by 8″ can significantly improve the signal strength. If the signal remains poor or unstable after relocation, consider using a radio signal range extender.
Detection zone
When choosing where to place the detector, perform the detection zone test to accurately determine the sector in which the device detects motion.
When choosing the installation site, consider the detector’s horizontal viewing angle and the width of the detection zone. Incorrect placement of the detector may cause false alarms.
| x | 3.3 | 6.6 | 9.9 | 13.2 | 16.5 |
| xx/2, ft | 0.43 | 0.86 | 1.30 | 1.73 | 2.17 |
| xx, ft | 0.86 | 1.72 | 2.60 | 3.46 | 4.34 |
Do not install the detector
- Near any metal objects or mirrors that can cause signal attenuation and screening.
- Opposite trees or bushes in the detection zone of a PIR sensor of the detector.
- In front of furniture, glass, or other constructions that may block the detector’s view.
- In places where electrical panels, air conditioning units, downspout pipes, or other constructions are located in the device’s detection zone.
- In front of water reservoirs or pools if they are located in the detection zone of the detector.
- In places with low or unstable Jeweller and/or Wings signal strength.
- Closer than 3.3 ft to the hub or radio signal range extender.
Installation
Before installing Curtain Outdoor Mini Jeweller, ensure that you have chosen the optimal location that complies with the requirements of this manual.
There are three options for installing Curtain Outdoor Mini Jeweller:
- On the SmartBracket mounting panel. SmartBracket allows you to install the detector on a vertical or horizontal surface.
- On the angle mount. It allows you to install the detector parallel to the guarded facility’s wall. The detector can be installed on the angle mount with the SmartBracket mounting panel.
- On a third-party mount. The detector can be installed on a third-party mount with the SmartBracket mounting panel.
When using a third-party mount, ensure that Curtain Outdoor Mini Jeweller is fixed vertically or horizontally. Deviation from the vertical or horizontal axis affects the detection area of the detector.
Before installation, set the required detection mode on its enclosure.
To install the detector:
- Remove the SmartBracket mounting panel from the detector. Unscrew the holding screw first and slide the panel down.
- Fix the SmartBracket panel using double-sided adhesive tape or other temporary fasteners. The mounting panel can be installed on a vertical or horizontal surface or in a corner of the premises using the mount angle.
The recommended installation height up to 16.4 ft on the ceiling or 3.3 ft on a side surface, depending on the protected area size.
Double-sided adhesive tape can only be used for temporary installation. The device attached by the tape may come unstuck from the surface at any time. As long as the device is taped, the tamper will not be triggered when the device is detached from the surface,
- Set the Detection mode slider on the device enclosure to the required position.
- Place the detector on the SmartBracket mounting panel and run the Jeweller signal strength test and Wings signal strength test. The recommended signal strength is two or three bars. With a signal strength of one or zero bars, we do not guarantee the device will operate stably. Consider relocating the device, as repositioning even by 8″ can significantly improve the signal strength. If the signal remains poor or unstable after relocation, consider using a radio signal range extender.
- Perform the detection zone test. To check the motion detector, walk around the premises while observing the LED indicator and determine the detection zone of the detector. The maximum range of motion detection is 16.4 ft. If the detector does not respond to movement during the test in 5 cases out of 5, relocate the device.
- Remove the detector from the SmartBracket mounting panel.
- Use bundled screws to attach SmartBracket / the angle or third-party mount to the surface.
- If the detector is installed directly on the mounting panel, attach the device to it. When installing the detector to the angle or third-party mount, first attach the SmartBracket mounting panel to the mount using bundled screws. Then, install the detector on the mounting panel.
- Leave the device’s detection zone (horizontal angle is 15°) and ensure there is no movement within the detector’s zone of view. This is necessary for the correct calibration of the masking sensor. During calibration, the detector’s LED indicator will flash green every 0.5 sec. Calibration takes up to 2 minutes.
Calibration starts automatically after installing the detector on the mounting panel.
- Tighten the holding screw on the bottom of the detector enclosure. The screw is needed for more reliable fastening and protection of the detector from quick dismantling.
If the LED indicator is not activated after installing the detector on SmartBracket, check the tamper status in the Ajax app, the integrity of the fastening, and the tightness of the detector fixation on the panel. You will receive a notification if the detector is detached from the surface or removed from the mounting panel.
Maintenance
Regularly check the functioning of the detector. The optimal frequency of checks is once every three months. Clean the detector enclosure of dust, cobwebs, and other contaminants as they emerge. Use soft, dry wipes suitable for equipment maintenance.
Do not use substances that contain alcohol, acetone, gasoline, and other active solvents to clean the device.
Pre-installed batteries provide up to 3 years of the detector’s autonomous operation. When the battery is low, the system will send a corresponding notification to Ajax apps. In case of an alarm, the LED indicator will smoothly light up and go out.
