Outdoor Bidirectional Security Motion Sensor Curtain Ajax DualCurtain Outdoor
The Ajax DualCurtain Outdoor Wireless curtain motion sensor is designed to detect and prevent entry into the protected area. The detector ignores animals up to 80 cm and birds. Weather factors also do not cause false positives. The device is protected from unauthorized exposure by intruders — varnishing, dismantling, hanging, protected from dust and splashes, operates at an air temperature below 0 ° C, the range of operation is adjustable up to 30 meters.
The principle of operation of the Ajax DualCurtain Outdoor street motion detector
The Ajax DualCurtain Outdoor Outdoor motion sensor detects human movement using two built-in independent IR sensors that capture the infrared radiation of living beings. The data that the device receives is checked by the two-factor ELSA algorithm. It detects similarities and spectral images between the signals of the two sensors, which helps to avoid triggering false alarms. The range of the sensor is adjustable in the range of up to 30 meters, 15 meters in each direction.
Features of Ajax DualCurtain Outdoor Wireless Street Motion Sensor
Detection accuracy
Two optical systems with narrow viewing sectors are placed on both sides of the detector. Each of the systems operates on the basis of two IR sensors. Sensor detection accuracy is at a high level due to temperature compensation. The signals given by the sensor are analyzed by a two—factor algorithm, and if two sensors simultaneously detect the movement of a person, the sensor raises an alarm.
Detecting objects in the near zone
The DualCurtain Outdoor Wireless Street motion Sensor uses protected area expansion technology. When the upper IR sensor of the sensor is turned on, it receives an additional narrow viewing sector directed at an angle of 40 degrees down relative to the main sector. The mode allows two sensors to detect movement when a person enters a protected perimeter, leveling the blind spot characteristic of such sensors. When the user activates "Near-field Detection", the sensor starts monitoring windows and passageways that animals do not have access to. The proximity of the detection zone vectors 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 guarded perimeter of the DualCurtain Outdoor and eliminate false alarms on 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.
