AJAX Alarmanlage - DualCurtain Outdoor

AJAX DualCurtain Outdoor

Wireless bi-directional curtain motion detector for outdoor use

Effective Outdoor Protection
DualCurtain Outdoor controls the property without generating alarms for people already inside. Two independent optical systems with narrow viewing areas and flexible settings enable precise adjustment of the detection range of 30 meters and eliminate possible sources of false alarms. The unique ELSA software reacts to intruders and ignores triggers such as natural disturbances and pets.

Technical accuracy
On the sides of the detector there are two optical systems with narrow viewing areas, each equipped with two PIR sensors. Thanks to temperature compensation, detection is always accurate. The sensor signals are analyzed with our new digital ELSA algorithm. Only when two sensors from the same optical system detect human movement at the same time will the detector trigger an alarm.

Efficiency at close range

DualCurtain Outdoor features protected area expansion technology that is unique among outdoor curtain motion detectors. When close range detection is set, an additional narrow viewing area is activated for the detector's top PIR sensor, directed at an angle of 40 degrees downwards towards the main sector. This feature allows both sensors to detect movement when a human crosses the protected area in close proximity to the detector itself, solving the blind spot problem typical of this type of detector.

Close range detection is designed to protect windows and other passageways where animals cannot access. The proximity of the vectors of the detection zones significantly reduces the effectiveness of pet immunity.

A housing. Two independent detectors
The detection range of the two optical systems is set independently of each other. This allows you to precisely define the area that DualCurtain Outdoor is guarding 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 downpipe on the facade. In the app you can adjust the sensitivity or disable one of the optical systems.

Safe against attacks
DualCurtain Outdoor cannot be blinded or deactivated unnoticed, even if Ajax is disarmed. The detector's optical systems are reinforced with advanced masking monitoring sensors that respond to obstacles as well as masking or painting of the lenses. The tamper protection does not allow the device to be removed from the holder unnoticed. And 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.
