AJAX DualCurtain Outdoor Detector
♦ AJAX DualCurtain Outdoor Detector – AJAX DualCurtain Outdoor detector features 2 optical systems with narrow viewing sectors and an adjustable 15m range.
Each system is equipped with 2 PIR sensors, supported by temperature compensation, with signals analyzed by AJAX ELSA digital algorithm and if 2 sensors of the same optical system simultaneously capture human motion, the detector activates an alarm.
DualCurtain Outdoor features technology to expand the protected area. When Near Area Detection is enabled, the detector’s upper PIR sensor receives an additional narrow viewing sector directed at the angle of 40 degrees down against the main sector.
The feature allows both sensors to detect movement when a human crosses the protected perimeter closely to the detector’s body, addressing the problem of the blind spot. Near Area Detection is designed to protect windows and other passages that animals have no access to. The proximity of the detection zones’ vectors significantly reduces the efficiency of pet immunity.
During setup, the detection range of the 2 optical systems is adjusted independently. This allows installers to precisely set the perimeter guarded by DualCurtain Outdoor and avoid false alarms caused by a bush swaying in the wind or people passing on a public sidewalk.
To ensure that the detector’s field of view is not blocked by a column or downpipe on a facade, the optical systems can be shifted vertically. Within the app, installers can adjust the sensitivity or deactivate one of the optical systems
There’s also anti-masking, tamper and frequent pings by a hub and this ensures DualCurtain Outdoor can’t be unnoticeably blinded or disabled even if a system is disarmed. These advanced masking sensors responds to obstacles, covering and painting the lenses. And the tamper will not allow a sensor to be removed from a mount without generating an alarm event.
Thanks to regular polling, even if the detector is instantly destroyed, it will take the hub less than a minute to detect the loss of communication and inform a central monitoring station and users about the problem.
Due to its low energy consumption, DualCurtain Outdoor operates for up to 4 years from pre-installed batteries. A monitoring station and users will be warned in advance about the need for the device maintenance as a low battery notification via the app.
To add a detector to the system, all installers do is scan the QR code with the Ajax app, then assign a name and a room to it, configure the device in the app in real time while testing detection zones and communication. If necessary, the detector can be disabled or its system parameters can be reconfigured remotely, without site visits.
