DualCurtain Outdoor
Wireless outdoor bidirectional curtain motion detector
Detection - 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.
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.
What is temperature compensation in motion detectors?
Motion detectors track the movements of heat-emitting objects. They are configured in such a way as to react to people from their first steps in the protected area and to filter out false signals from natural interference and animals. A special software algorithm for processing the PIR sensor signal has been developed for each Ajax motion detector to increase the accuracy and efficiency of operation.
Under ideal conditions, the human body temperature (36.6°C on average) differs from the ambient temperature. Their contrast allows the motion detector to record the movement of a person in space accurately. In situations where the ambient temperature is very close to body temperature, temperature compensation is necessary.
Temperature compensation is implemented at the software level and is based on regular measurements of the ambient temperature by the detector. At an ambient temperature of 14°C to 42°C, with each measurement, the detector introduces a correction according to the table of correction factors stored in its memory, i.e., either increases or decreases the sensitivity of PIR sensors.
