In the past year we have strengthened our expertise in engineering so that we can focus more on outdoor security, the most complex area for security equipment manufacturers. Outdoor detectors are often a problem for professionals. Natural disturbances, heat, rain and snow cause many false alarms. We started working on an outdoor motion detector with a narrow viewing angle and were able to make it happen thanks to our experience in developing our own optical systems and software filters for false alarms.

And we made something special. DualCurtain Outdoor combines patented lens systems, a new digital algorithm to counteract false alarms based on millions of triggers, a nearby motion detection option and highly flexible settings. All this works for years on batteries.

Two detectors in one housing

Each DualCurtain Outdoor element embodies the idea of technical precision. Flowing lines, deep-set lenses and masking sensors form a streamlined rainproof housing. The SmartBracket mounting panel allows you to easily and securely attach the detector to the surface while closing the mounting panel.

The sides of the detector are set independently. The rear panel controls allow you to determine the detection distance for each side, the detection activation in the vicinity of a detector and the vertical shift of the viewing sector by 3° so that parts protruding from the facade do not obstruct the view of the detector.

In the Ajax app, each side of the detector can be controlled individually. This allows you to enable/disable IR or mask sensors, make them permanently active regardless of the enable mode, and adjust sensitivity. The app allows you to flexibly customize the interaction with the detector. This allows you to set input/output delays, link siren activation to a particular side or create an automation scenario for a detector alarm.

DualCurtain Outdoor protects the most remote areas thanks to a connection range of up to 1.700 meters from the hub. And in complex locations, ReX signal amplifiers can help build robust outdoor security regardless of scale.

Double filtering against false alarms

With two IR sensors on each side, DualCurtain Outdoor works effectively against false alarms. The detector does not respond if only one sensor has detected motion. When both sensors are activated, the detector activates the ELSA special digital algorithm. In a fraction of a second, ELSA performs a three-step signal analysis. Natural disturbances and animals are filtered out and ELSA determines whether or not an alarm should be raised.
