Abstract

PURPOSE: To avoid a sensing hindrance means by arranging sensing cables for an intrusion sensor for detecting intrusion of a man or the like in the inside of a protection fence from intrusion arranged along the periphery of a specified section and secretly keeping the installation condition. CONSTITUTION: A vibration-sensing type sensor is used as an intrusion sensor 21. A sensing cable 22 is arranged in the inside of a pipe line-forming member 33 for a protection fence 31 from intrusion. One end of the cable 22 is led to a control box 23 in the vicinity of the protection fence 31 through a connection pipe 41 embedded in the ground, and the other end is connected to a terminator 24 provided in a support 32. When an invader climbs up the fence 31 or imparts a shock, vibration and shocks acting on the fence 31 are detected through the cable 22 and since the cables 22 are embedded and concealed, a sensing hindrance means such as cutting off of the cable 22 can be avoided.
