PROBLEM TO BE SOLVED: To achieve improvements in terms of timely detection for an intruder, difficulty in the detour, removal of a detection sensor by the intruder, and function suspension, and the like; abrasion resistance of a vibration sensor; enhanced water proofing; easy equipment installation; detection of broken glass; use for individual identification; crime prevention for an ATM; and management for time and frequency of door opening and closing, and the like. SOLUTION: The installation-allowing position/place of a detector is expanded to a wide range. Burying the detector allows no visual observation by the intruder and making a preliminary measure difficult. A vibration sensor-incorporating box made of a hard metal is prepared to install the box on a soft metal. A poor conductor material for vibration is formed to a transmission material by laminating a metallic plate on the poor conductor material. Water proofing structure is applied to the buried detector made of the metal. Cobble stone and soil are hard to transfer the vibration. Thus, the buried detector is simply installed by expanding or branching the buried detectors so as to cover the wide range. The buried detector is simply inexpensively installed for the ATM, the entrance and exit for a truck in a factory, and a building corridor, and the like. COPYRIGHT: (C)2005,JPO&NCIPI
