Ajax Dualcurtain Outdoor Wireless Two-Way Curtain Motion Detector Aj-Dualcurtainoutdoor-W

DualCurtain Outdoor monitors the perimeter without creating obstacles for people already inside. Two independent optical systems with narrow field of view sectors and flexible settings allow for precise adjustment of 30 meters of detection range, excluding possible sources of false alarms. The unique ELSA software responds to intruders, excluding causes that can trigger the alarm such as natural disturbances and pets

On the sides of the detector there are two optical systems with a narrow field of view, each equipped with two PIR sensors. Thanks to the temperature compensation, the detection is always accurate. The sensor signals are analyzed by our new digital algorithm ELSA. The detector activates the alarm only if two sensors of the same optical system simultaneously detect the movement of people.

DualCurtain Outdoor features a technology that expands the protected area, a unique feature among outdoor curtain motion detectors. When Near Area Detection is activated, the detector's upper PIR sensor receives an additional narrow sector of vision, directed at a 40-degree angle downwards from the main one. This feature allows both sensors to detect motion when a person crosses the protected perimeter close to the device's body, solving the blind spot problem, which is typical for such detectors. Near Area Detection is designed to protect windows and other passages that are inaccessible to animals. The proximity of the detection zones significantly reduces the effectiveness of pet immunity.

The detection range of the two optical systems can be adjusted independently. This allows you to precisely set the perimeter protected by DualCurtain Outdoor and avoid false alarms caused by a bush blowing in the wind or people walking on a public sidewalk. To prevent the detector's field of view from being obstructed by a column or a gutter running down the facade, the optical systems can be oriented vertically. In the app, you can adjust the sensitivity or deactivate one of the optical systems.

DualCurtain Outdoor cannot be subtly obscured or disabled even if the security system is disarmed. The detector's optical systems are reinforced with advanced anti-masking sensors that respond to obstacles, coverings and lens paint. The anti-tampering mechanism will not allow the device to be removed from the mount without being noticed. And even if the detector is destroyed instantly, it takes less than a minute for the hub to detect the loss of communication and inform a monitoring station and users of the problem.

Thanks to its low energy consumption, DualCurtain Outdoor can run for years on the pre-installed batteries. The monitoring station and users will be notified in advance if the device requires maintenance.
