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.
Know-how
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.
Near Area Detection mode is a patented technology of Ajax Systems.
Near Area Detection technology is supported by both DualCurtain Outdoor optical systems
Settings
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

Outdoor motion detectors for alarm
Protecting the perimeter of both private premises and enterprises needs signal protection. Installing a motion sensor is suitable for detecting and fixing movement in the controlled area.
Types of detectors and how they work
Types of outdoor detectors by location
- Perimetric — the type of motion detectors installed along the territory's perimeter which determines the movement in the protected area.
- Peripheral presence sensors — are mounted on the facades of houses and fences. Such a sensor detects a moving object if the action limits are violated.
The principle of operation of outdoor security detectors
An electronic security motion detector for outdoor installation is equipped with a microwave, optical or acoustic sensor, and often a signalling device for lighting control. The sensor captures changes in the field of action, after which, when presence is detected, it transmits an alarm signal to the alarm control panel, which activates the siren.
Presence detectors for signalling, for the most part, operate in a diameter of five metres, but industrial sensors detect movement at a distance of 10-15 metres. A motion detector is used for installation in industrial areas, to which a flashlight or spotlight is connected.
According to the type of radiation, motion sensors for alarms are divided into
- Infrared sensor — used to protect the land. Infrared motion detectors for alarms are sensitive to the temperature of the human body in motion, which is recognised by radiation. This type of radio sensor is used in domestic conditions.
- Microwave sensor — the operation concept is based on the principle of Doppler's rays. The sensor emits a constant signal that a person will not feel, but it activates the siren when the boundaries are violated.
- Ultrasonic sensor — the principle of operation is similar to the previous type of sensor. This kind of motion sensor can work around the clock.
Advantages of having a motion detector
The presence detector for outdoor installation protects the premises and property owners. Additionally, it can be equipped with a video surveillance camera and control the light. The motion detector can control the alarm, halogen light, fire system and other protection mechanisms.
Installation of the street presence sensors
Presence detector installation methods depend on the selected device type. Most detectors are connected using a 220V power cable, but wireless outdoor security motion sensors are becoming increasingly popular. This type of detector is more efficient than a wired one, as it continues to work in extreme conditions due to autonomous communication. In most cases, wireless outdoor motion sensors are operated by batteries or accumulators.
How to connect the presence sensor:
- It is necessary to develop a motion sensor connection project before installation. To do this, you need a site plan. When planning the detector placement, it is worth considering that communication pipes, especially heating ones, should be far from it. And also, users need to avoid direct sunlight on the device and obstructions to the signal.
- The instructions will be provided with the chosen detection device, where there is an item: installation tips. Depending on the type of outdoor detector, it must be connected in parallel or in series. When installed in parallel, the sensor and the central panel are opposite. When connected in series, the detector is mounted first, and then the signal receiver or switch.
- The following steps vary by manufacturer. In most cases, a mounting kit is included with the motion sensor.
Outdoor bidirectional security motion curtain detector Ajax DualCurtain Outdoor Jeweller
The DualCurtain Outdoor Jeweller wireless motion sensor detects and prevents intrusion in a guarded area. The detector ignores animals up to 80 cm and birds. Weather factors also do not cause false alarms. The device is protected from unauthorised influence by intruders — varnishing, dismantling, hanging, protected from dust and splashes and operates at air temperatures below 0 ° C. The operating range is adjustable up to 30 metres.
The principle of operation of the DualCurtain Outdoor Jeweller motion detector
The DualCurtain Outdoor Jeweller motion sensor for signalling detects human movement using two built-in independent IR sensors that detect the infrared radiation of living beings. A two-factor ELSA algorithm checks the data received by the device. It determines the similarities and spectral patterns between two sensor signals, which helps to avoid false alarms. The sensor range is adjustable up to 30 metres, 15 metres in each direction.
Features of the wireless outdoor motion detector DualCurtain Outdoor Jeweller
Detection accuracy
Two optical systems with narrow viewing sectors are placed on both sides of the detector. Each of the systems operates based on two IR sensors. The sensor detection accuracy is high due to temperature compensation. A two-factor algorithm analyses the signals that the sensor gives, and if two sensors record the movement of a person simultaneously, the sensor raises the alarm.
Detection of objects in the near zone
The DualCurtain Outdoor Jeweller wireless outdoor motion detector uses technology to expand the protected area. When the top IR sensor is turned on, it receives an additional narrow sector of view directed at an angle of 40 degrees downward from the primary sector. The mode allows two sensors to detect movement when a person enters a protected perimeter, levelling the blind zone characteristic of such sensors.
When the user activates "Near Detection", the sensor monitors windows and passages that animals cannot access. The proximity of the vectors of the detection zones reduces the effectiveness of immunity to animals.
One housing — two independent sensors
It is possible to adjust the range of the two sensors independently. This allows you to accurately set the secure perimeter of the DualCurtain Outdoor Jeweller and eliminate false alarms from random passers-by or trees swaying in the wind. In the mobile application, you can adjust the sensitivity of wireless sensors or deactivate one optical system.
Resistant to deactivation attempts
DualCurtain Outdoor Jeweller is resistant to interference. Thanks to the tamper on the device case, removing the device from the mount will not be possible — an alarm will be triggered. The optical systems of the detector are equipped with masking sensors that react to obstacles, painting the body and curtaining the device.
The DualCurtain Outdoor Jeweller cannot be blinded or silently disabled even if the burglar alarm is disarmed. Even if the wireless motion sensor DualCurtain Outdoor Jeweller is destroyed instantly, the hub control panel will detect the loss of communication in less than a minute and inform the security console and users about the problem.
Motion detector autonomy for DualCurtain Outdoor Jeweller alarm
The DualCurtain Outdoor Jeweller has optimised power consumption, which allows the device to work for up to four years without changing batteries. The wireless sensor will warn users of the security system to replace the batteries.
Convenient installation of the motion sensor
The outdoor motion sensor for the alarm is mounted on the SmartBracket mount, without harm to repair and without disassembling the sensor housing. The wireless device connects to the smart control panel via a mobile application.
To add a wireless motion sensor to the system, you need to scan the QR code with the Ajax application and assign a name and room to the device.
Setting up the outdoor detector happens in real time with detection and communication zone tests. You can turn off the outdoor motion sensor or reconfigure the system parameters without leaving the guarded site.
Connection of a wireless detector to the Hub and ocBridge Plus and uartBridge integration modules is not possible. The security motion sensor works with Hub Plus, Hub 2, Hub 2 Plus and the ReX signal repeater.
