FIELD: means of protection.
SUBSTANCE: invention relates to technical means of protection of extended linear objects. Sensors used are mobile detection means (MDM), made with possibility of protection of linear object against unauthorized actions on selected local area of presence in the presence of near it OPL. MDM, providing protection of selected local area, are connected via radio channel with transceiver arranged on nearest support OPL, on which there is also electric power take-off device from OPL. As MDM mobile means of detection can be used, made with possibility of functioning on different physical principles.
EFFECT: technical result consists in improvement of the security system reliability.
