The bidirectional motion detector DualCurtain Outdoor with HDR camera from Ajax is a reliable partner that carefully monitors the outdoor area and reports every movement immediately. The high-quality motion detector naturally ignores pets because it only pays attention to people. Two independent optical systems with narrow fields of view and flexible settings enable a precise setting of the detection range of 30 meters and eliminate possible sources of false alarms. The unique ELSA software reacts to intruders and hides triggers such as natural disturbances and pets.

- Wireless connection
- Dustproof and waterproof
- Independent adjustment of each side
- Flexible settings of the detection areas
- Monitors an area up to 30m in length
- Bidirectional motion detector with a narrow detection angle

High Technical Accuracy
The two optical systems on the sides of the detector are each equipped with two PIR sensors. Thanks to the temperature compensation, the detection is always accurate. The sensor signals are analyzed with Ajax's new digital ELSA algorithm. The detector only triggers an alarm if two sensors of the same optical system detect human movement at the same time.

Efficiency at Close Range
Thanks to the use of a special technology, which is unique for these outdoor motion detectors and patented by Ajax, within the DualCurtain outdoor motion detector, the protected area is expanded. When short-range detection is set, an additional narrow field of view is activated for the upper PIR sensor of the detector, which is directed at an angle of 40 degrees downwards towards the main sector. This feature enables both sensors to detect movement when a person crosses the protected area in close proximity to the detector itself, thereby solving the blind spot problem typical of this type of detector.

One housing - Two Independent Detectors
The detection range of the two optical systems is set independently of one another. This allows you to precisely define the area guarded by DualCurtain and avoid false alarms caused by a bush swaying in the wind or by passers-by on a public sidewalk. The optical systems can be moved vertically so that the detector's field of vision is not blocked by a column or a downpipe on the facade. In the app you can adjust the sensitivity or deactivate one of the optical systems.

Safe Against Attacks
The DualCurtain Outdoor cannot be blinded or deactivated unnoticed, even when Ajax is disarmed. The detector's optical systems are reinforced with advanced anti-masking sensors that respond to obstacles, as well as masking or painting of the lenses. The manipulation protection does not allow the device to be removed from the holder unnoticed. Even if the detector is destroyed immediately, it takes the hub less than a minute to detect the loss of communication and notify a monitoring center and users of the problem.

Excellent Autonomy
Due to its low energy consumption, DualCurtain Outdoor works for years with pre-installed batteries. A monitoring center and users are informed in advance of the need for equipment maintenance.

Problem-Free, Uncomplicated Installation
The process of connecting and configuring DualCurtain Outdoor saves the installer 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 and assign a name and room to the device. Configure the device in the app in real-time while testing detection areas and communication. If necessary, you can deactivate the detector or reconfigure its system parameters remotely without the need for an on-site visit.
