METHOD FOR COMBINED PROTECTION OF PERIMETER OF EXTENDED OBJECT Russian patent published in 2016 - IPC H04N7/18 H04B10/00 

FIELD: safety.

SUBSTANCE: invention relates to protection of perimeters of objects and can be used for signalling blocking perimeters of objects and extended boundaries on flat and rough terrain. Method includes making seven security boundaries: first warning boundary by laying of extended sensitive element in form of a fibre-optic cable; second warning boundary, which is made similarly; third boundary in form of electrical shock hazard obstacle; fourth security boundary, which is made similar to first and second; fifth security boundary - boundary of perimeter of object, which is made in form of mesh enclosure, wherein enclosure is fitted with a spiral security barrier and at least one sensitive element; device of sixth security boundary - crossing trace strip, and seventh boundary, which is similar to first, second and fourth borders. Fifth boundary is equipped with means of heat- and video surveillance, audio warning and illumination, sensitive element is connected to optical sensors of alarm signalling. All security boundaries is controlled by means of fibre-optic vibration-seismic detector of reflectometric operating principle.

EFFECT: method improves reliability of protection of object, particularly when operating in conditions of increased electromagnetic radiation and in any weather conditions.
