摘要

PROBLEM TO BE SOLVED: To solve the problem of a conventional detector structure in which it is difficult to discriminate a person from a matter, and presence of a detection means is known by an intruder when set on a porch in front of an entrance door or the like.;SOLUTION: The vibration detector 13 including films 9a and 9b for dust prevention and water prevention is set on a porch 15 in front of an entrance door 14 to detect vibration applied onto the upper surface of the porch 15. By detecting vibration, a moving matter can be discriminated from a non-moving matter. Therefore, a moving person can be discriminated from a stationary matter. Since the vibration detector 13 is buried in the porch 15 to hide the vibration detector itself from the circumference, confidentiality can be enhanced.;COPYRIGHT: (C)2007,JPO&INPIT
