DualCurtain Outdoor wireless bidirectional curtain motion detector

Product information

On the sides of the DualCurtain Outdoor wireless detector there are two optical systems with narrow viewing sectors, each equipped with two PIR sensors. Thanks to temperature compensation, detection is always accurate. Sensor signals are analyzed by our new ELSA digital algorithm. Only if two sensors of the same optical system simultaneously capture human motion, the detector activates an alarm.

Efficiency in the near area

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

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.

One enclosure. Two independent detectors

The detection range of the two optical systems is adjusted independently. It allows you 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. So that the detector’s field of view is not blocked by a column or downpipe on a facade, the optical systems can be shifted horizontally. In the app, you can adjust the sensitivity or deactivate one of the optical systems.

• The range is determined within 15 meters for each optical system
• Sector of view of each optical system shifts 3° horizontally
• Both or only one optical system can be used

Resistant to attacks

DualCurtain Outdoor can not be unnoticeably blinded or disabled even if Ajax is disarmed. Detector’s optical systems are reinforced with advanced masking sensors that respond to obstacles, covering and painting the lenses. The tamper will not allow to unnoticeably remove the device from the mount. And 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.

Outstanding autonomy

Due to its low energy consumption, DualCurtain Outdoor operates for years from pre-installed batteries. A monitoring station and users will be warned in advance about the need for the device maintenance.

• Up to 4 years of battery life
• In-app battery charge status
• Low battery notification

Technical specifications

Detection:

• Sensitive elements 4 × IR sensor
• Motion detection distance 4–13 m for each side (When installed at a height of 0.8–1.3 meters. Adjusted separately for each side using sliders on the detector rear panel).
• Viewing angles: horizontal — 4.5°; vertical — 90°
• Motion detection speed: 0.3 to 2.0 m/s (The direction of the detector lens should be perpendicular to the intended path of entry into the facility).
• Near zone detection. When enabled, the detector's upper IR sensor receives an additional sector of view, directed at an angle of 40° downward of the main sector. This is necessary to detect motion near the detector and reduce blind spot. Adjusted separately for each side using sliders on the detector rear panel.
• Viewing angle shift. When enabled, the optical system viewing angle can be shifted by 3° in the horizontal plane. Adjusted separately for each side using sliders on the detector rear panel.
• Sensitivity: 3 levels (Adjusted by a PRO or user with admin rights in the Ajax app).
• Pet immunity: height: up to 80 cm; weight: irrelevant
• Protection from false alarms: SmartDetect; ELSA
• Temperature compensation. Effective motion detection at temperatures from -25°C to +60°C.

Recommendations:

• The detector is installed at a height of 0.8–1.3 meters from ground level when used to protect doors, arches, other passages, or the area in front of windows. Otherwise, if the detector is used to protect windows, it is installed at a height of 0.5–0.6 meters from the window sill.

Anti-sabotage protection:

• Tampering alarm. Alerts of attempts to detach the detector from the surface or remove the mounting panel.
• Protection against spoofing: Device authentication
• Anti-masking system. DualCurtain Outdoor Jeweller detects the following types of masking:
• Obstacles in front of the detector's lenses at a distance of up to 10 centimeters (depends on the material).
• Painting over the detector's lenses.
• Taping the lenses or the detector's sides.
• Lost connection detection: from 36 s (The time to detect the communication loss depends on the Jeweller (or Jeweller/Fibra) settings).

Enclosure

• Dimensions: 174 × 123 × 88 mm
• Weight 615 g
• Operating temperature range −25°C to +60°C
