DualCurtain Outdoor Jeweller
Wireless outdoor bidirectional curtain motion detector
Protecting property boundaries
DualCurtain Outdoor controls your property perimeter without creating obstacles for people who are already inside. Two independent optical systems with narrow viewing sectors and flexible settings allow you to accurately adjust 30 meters of the detection zone, excluding possible sources of false alarms. The ELSA (Extended Live Signal Analysis) unique software reacts to intruders, screening out triggers like natural interferences and pets.
Engineering accuracy
On the sides of the detector there are two optical systems with narrow viewing sectors, each equipped with two PIR sensors. Thanks to temperature compensation, detection is always accurate. Sensor signals are analyzed by our new ELSA digital algorithm. Only if two sensors of the same optical system simultaneously capture human motion, the detector activates an alarm.
- Instant response to intruder
- Pet immunity
Efficiency in the near area
DualCurtain Outdoor features a technology to expand the protected area, which is unique among outdoor curtain motion detectors. When Near Area Detection is enabled, the detector’s upper PIR sensor receives an additional narrow viewing sector directed at the angle of 40 degrees down against the main sector. The feature allows both sensors to detect movement when a human crosses the protected perimeter closely to the detector’s body, addressing the problem of the blind spot, which is a typical problem of such detectors.
Near Area Detection is designed to protect windows and other passages that animals have no access to. The proximity of the detection zones’ vectors significantly reduces the efficiency of pet immunity.
Near Area Detection mode is a patented technology of Ajax Systems.
Near Area Detection technology is supported by both DualCurtain Outdoor optical systems
One enclosure. Two independent detectors.
The detection range of the two optical systems is adjusted independently. It allows you to precisely set the perimeter guarded by DualCurtain Outdoor and avoid false alarms caused by a bush swaying in the wind or people passing on a public sidewalk. So that the detector’s field of view is not blocked by a column or downpipe on a facade, the optical systems can be shifted horizontally. In the app, you can adjust the sensitivity or deactivate one of the optical systems.
- The range is determined within 15 meters for each optical system
- Sector of view of each optical system shifts 3° horizontally
- Both or only one optical system can be used
Resistant to attacks
DualCurtain Outdoor can not be unnoticeably blinded or disabled even if Ajax is disarmed. Detector’s optical systems are reinforced with advanced masking sensors that respond to obstacles, covering and painting the lenses. The tamper will not allow to unnoticeably remove the device from the mount. And even if the detector is instantly destroyed, it will take the hub less than a minute to detect the loss of communication and inform a central monitoring station and users about the problem.
- Anti-masking
- Tamper
- Frequent pings by a hub
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 communication range in open space
- Data encryption
- Notification of jamming and connection loss
- Photo verification in less than 9 seconds
Outstanding autonomy
Due to its low energy consumption, DualCurtain Outdoor operates for years from pre-installed batteries. A monitoring station and users will be warned in advance about the need for the device maintenance.
- Up to 4 years of battery life
- In-app battery charge status
- Low battery notification
Installation without brain teasers
The process of connecting and configuring DualCurtain Outdoor saves the installation engineer’s time in the best possible way. To add a detector to the system, all you have to do is scan the QR code with the Ajax app, assign a name and a room to it. Configure the device in the app in real time while testing detection zones and communication. If necessary, the detector can be disabled or its system parameters can be reconfigured remotely, without site visits.

Detection
| Sensitive element |
4 × PIR sensors |
| Motion detection distance | 4–15 m for each side When installed at a height of 0.8 to 1.3 m. Adjusted separately for each side using sliders on the detector rear panel. |
| Viewing angles | horizontal — 4.5° vertical — 90° |
| Motion detection speed | 0.3 to 2.0 m/s The direction of the detector lens should be perpendicular to the intended path of entry into the facility. |
| Near zone detection | When enabled, the detector's upper IR sensor receives an additional sector of view, directed at an angle of 40° downward of the main sector. This is necessary to detect motion near the detector and reduce blind spot. Adjusted separately for each side using sliders on the detector rear panel. |
| Viewing angle shift | When enabled, the optical system viewing angle can be shifted by 3° in the horizontal plane. Adjusted separately for each side using sliders on the detector rear panel. |
| Sensitivity | 3 levels Adjusted by a PRO or user with admin rights in the Ajax app. |
| Pet immunity | height: up to 80 cm weight: irrelevant |
| Protection from false alarms | SmartDetect ELSA Software algorithms. |
