System of security

The system of «Dunay» – a distributed acoustic sensor influences for security systems.

The system allows to fix the approaching to the guard zone and the border crossing throughout the whole perimeter (up to 40 km or to 75 km with ROPA). At approaching of person the car or while earthwork near protected object, the Dunay system is transmitting an alarm event to the operator’s computer indicating the source place with an accuracy of 10 meters. The system aenables detection and localization of a set of simultaneous influences too. This 3U device unit has three slots for: receiving and transmitting unit, amplifier module and embedded server for processing. The system has redundant power supplies. The sensitive element is an optical fiber. Customer can use fibers of the optical cable has already constructed in ground. System allow locate any activities causing ground and water vibration beyond 150 meters from fiber optic cabel.

The system received a patent № 2503879 on the monitoring device object in the pipeline. Dunay allows you to monitor the passage of defectoscope and cleaning pigs in pipes.
