The sensors are intended for the protection of direct perimeter sectors. The sites include industrial facilities, airports, sites of force structure, power plants, private premises, etc.
The principle of operation is based on generation of an invisible volumetric detection zone between the transmitter and the receiver.
When the intruder is crossing the detection zone, the receiver registers its alteration and generates the alarm.
FEATURES OF MICROWAVE BISTATIC SENSORS
Taking into account many years of operation of the sensors we can mark their high detection probability and good interference immunity. The sensors are easy to mount and adjust and do not require significant expenses on seasonal maintaining.
The sensors are immune to the influence of rain, snow, fog, lightning, icing, solar radiation, electromagnetic field up to 500 kV, vegetation, small birds and animals.
The wide choice of models differing in range, frequency and operational temperature allows to select the optimal variant for the perimeter protection in different climatic conditions.
We use traditional dry relay contacts as well as RS-485 and USB interfaces to control the sensors and to transmit the alarm signal.
Like this we make it easy to combine our sensors with many modern integrated security systems and popular control panel.
We use up-to-date effective algorithms for digital signal processing. Many years of manufacture and operation of our sensors allowed us to analyze the reliability of the equipment and correct the algorithms. As a result we achieved the maximal interference immunity and reliability of the signal processing.
Operation on 24,15 GHz allows to:
– use sensor in many countries all over the world without getting approval for frequency use;
– minimize the influence of different types of interference;
– provide narrow detection zone and make it possible to use the sensors on different sites.
Configuration of sensors using special software (under Windows) via USB allows to set the optimal operation mode, also remotely from the guard room via RS-485 interface.
The model with wireless configuration via Bluetooth on Android is available at the order.
The wide aperture of the parabolic antenna of the sensors BARRIER-500 allows to eliminate «dead zones» near Tx and Rx and to assure reliable performance under snow cover up to 0,9 m, grass up to 0,4 m and to provide high interference immunity for birds flying near antennas. As a result we minimize maintenance works on the protected site.
Improved design and signal processing algorithms used provide the reliable detection of the intruder and high interference immunity.
4 frequency letters eliminate the influence of adjacent sensors. Like this it is possible to put several sensors near each other.
