Definitions

• the invention relates to a device and a system for detection of a radio signal for the measurement, evaluation and analysis of the intensity of the radio signal for the purpose of early detection of an intruder in the guarded area.
• Fencing is mainly made up of ioad-bearing structure such as pillars, which carries the fillers such as mesh, carrying also the electronic sensors and materials, which create a protective field. In the event of a intrusion of the protective field the alarm is triggered. It is known the solution according to the utility model CZ2800, whose essence is that the perimeter fencing consists of at least one row, while between the rows there is modified connecting field, where on the mesh each row has attached sensor cable sensing the vibration of the mesh.
• a substantial disadvantage of this solution is the need to surround the guarded space by the tensioning rods and pipes for placing of a sensor cable and also the high costs on the professional installation of cabling. Another disadvantage is also the interruption of the detection zone in the points of entry into the guarded object. Another significant disadvantage of this solution is the fact that the detection cable does not have long service life thanks to the action of UV radiation of the sun on this cable and after about 10-15 years has to be replaced due to its reduced sensitivity. The disadvantage of this solution is the fact that the detection cable in its length works as an unwanted antenna. In storm activity and atmospheric discharges it then brings up a very big risk of induction of the atmospheric energy into this cable, what results in the destruction of the control units directly connected to this cable. The disadvantage of the solution is also a very exacting repair of the system in case of intentional sabotage by cutting of the sensing cable.
