The concealed location of the sensing elements allows to resolve several problems: impossibility of pre-reconnaissance, vandal resistance, and preservation of the secured area landscape. The concealed operation of the "Dunay" system prevents a potential trespasser from performing preparation and workup activities, which increases the chance of detecting a trespasser. The higher vandal resistance is crucial for remote areas, where equipment theft or damage is highly probable. And landscape preservation feature allows to use the system in specially protected cultural heritage areas.
No infrastructure and power supply units are needed throughout the monitoring zone. The vibro-acoustic sensor allows to discover underground tunnels and detect digging of passages. This version makes the "Dunay" system indispensable for industrial and sensitive facilities as well as for various polygons. The "Dunay" system has an open API (signal transmission via Ethernet), which allows it to be integrated into existing security systems. Video surveillance and "Dunay" system can be operated jointly, where an alarm signal orients a camera directly to a relevant zone section, so that an operator can see an event image on his monitor. The joint operation of "Dunay" and other security systems of a facility permits to decrease substantially the number of any nuisance alarms. The system allows an operator to recognize and mask routine safe events, such as vehicles or people passage in the permitted areas. "Dunay" has proven its efficiency in organizing the perimetral guarding of airports.
