Dualcurtain Outdoor


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.

Frequent pings by a hub
Security Grade

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.

Efficiency in the near area

DualCurtain Outdoor features a technology to expand the protected area, which is unique among outdoor curtain motion detectors.

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.
