PRODUCT INFORMATION

Product Code: 26072.81.WH1

The Ajax DualCurtain is a wireless outdoor bidirectional curtain motion detector. Two detectors in one Unique optical systems Masking sensors Flexible settings of
detection zones.

Engineering accuracy

On the sides of the 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.

Instant response to intruder Pet immunity

How the ELSA digital algorithm works:
Signal analysis is critical for the motion detector, which receives a minimum of information about the object in the protected area due to the 4,5° horizontal field of view. Precise analysis ensures quick response to humans, eliminating reaction on animals and natural interferences.
DualCurtain Outdoor uses ELSA, a three-step software algorithm that analyzes the signals from two narrowly focused PIR sensors of the optical system.

Patterns comparison

The signal amplitudes are verified against the pattern database. To create it, we analyzed thousands of curtain detector triggering's on people, animals, lights, and other natural interferences in various weather conditions. The signals must match the patterns that are typical for humans.

Time verification

When signals from both PIR sensors match the conditions — this is motion, and it is typical for a human —ELSA compares the time intervals when the signals received, determining whether the upper and lower sensors detected motion synchronously.
To reach a verdict whether it’s a threat or false alarm, ELSA needs less than a second.
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 typical problem 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 vertically. In the app, you can adjust the sensitivity or deactivate one of the optical systems.

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.

Guaranteed alarm delivery

● Two-way communication at a distance of up to 1,700 meters
● 5 ReX radio signal range extenders in security system
● Adjustable ping interval from 12 seconds

Outstanding autonomy

● Up to 4 years of battery life
● Charge level in the app
● Low battery notification

Installation without brain teasers

The process of connecting and configuring DualCurtain Outdoor saves the installation engineer’s time in the best possible way. To add a detector to the system, all you have to do is scan the QR code with the Ajax app, 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.
