Ajax Dualcurtain Outdoor - Dual Curtain Motion Detector

Protection against intruders.
The DualCurtain Outdoor protects the perimeter, thus giving people freedom of movement inside.
Two independent optical systems with narrow viewing sectors and flexible configurations allow you to precisely adjust a 30-meter detection range.
The exclusive ELSA software responds to intruders, tracking possible triggers such as natural interference and pets.
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. The sensor signals are analyzed by our new ELSA digital algorithm.
The detector triggers an alarm only if two sensors of the same optical system detect human movement simultaneously.

Efficiency in the immediate area
This detector has a technology to expand the protected area, something unique in outdoor curtain-type motion detectors.
When Near Area Detection is activated, the detector's top PIR sensor receives an additional viewing sector.
This feature allows a human to be detected when entering the perimeter close to the detector's own body. This avoids the blind spot problem, which is very common in these detectors.
Near Area Detection is designed to protect windows and other passageways that animals cannot access.
The Near Area Detection mode is a patented technology from Ajax Systems.
Near Area Detection technology is compatible with both optical systems of the DualCurtain Outdoor.

One body. Two independent detectors.
The detection range of the two optical systems is adjusted independently.
It allows you to precisely configure the protected perimeter and avoid false alarms.
In the app, the user can adjust the sensitivity or disable one of the optical systems.

Tamper-resistant.
Even if the Ajax system is disarmed.
The detector's optical systems are reinforced with masking sensors that detect obstacles, lens covering, and paint.
The tamper-proof system prevents the device from being removed from its mount imperceptibly.
In case of destruction, the hub takes less than a minute to report the problem to users.
