One housing. Two independent detectors.
Ajax DualCurtain Outdoor controls the property without obstacles for people who are already in the property to be secured. Two independent optical systems with narrow viewing areas and flexible Adjustment options allow precise adjustment of the detection range of up to 30 meters and exclude possible sources of The unique ELSA software reacts to intruders and hides triggers such as natural disturbances and Pets out.

Technical precision
On the sides of the outdoor 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 using the latest digital ELSA algorithm. Only when two sensors the same optical system simultaneously detects human movement detect, the detector triggers an alarm.

Efficiency at close range
DualCurtain Outdoor has a technology to extend the protected area, which is under the curtain motion detectors for Outdoor areas are unique. When the proximity detection is set, the upper PIR sensor of the detector will be additional narrow field of view is activated, which is at an angle of 40 degrees downwards towards the main sector. This function allows both sensors to detect movements when a person the protected area in the immediate vicinity of the detector itself which eliminates the problem typical for this type of detector of blind spot is solved.
The proximity detection was developed to protect windows and other passages to which animals cannot have access. The proximity of the detection zone vectors reduces the Effectiveness of pet immunity significantly.

Safe against attacks
The Ajax curtain motion detector cannot be blinded or deactivated unnoticed even when the alarm system is disarmed. The optical systems of the detector are equipped with advanced anti-masking sensors reinforced, which refers to obstacles as well as covering or painting the Lenses react. The tamper protection does not allow the device unnoticed from the bracket. And even if the detector is destroyed immediately, the Hub needs less than a minute, to detect the loss of communication and monitoring center and inform users about the problem.
