Abstract:
PROBLEM TO BE SOLVED: To provide a sound recognition theft prevention system which can surely detect an abnormal state at a remote position without being inhibited by an electromagnetic wave noise, when an abnormal state in which, a self ringing type theft prevention tag outputs a warning during occurrence of a theft act event, occurs and in which a same self singing type theft prevention tag can be used in adjacent shops.SOLUTION: Each of plural theft warning areas A, B, C comprises: a self-ringing type theft prevention tag 100A, 100B, 100C attached to a theft warning object and outputs an alarm sound; and a warning sound identification part 301, 302 for identifying an alarm sound output by the self-ringing theft prevention tag. The self-ringing type theft prevention tag comprises a warning sound output part 110 for outputting a specific alarm sound having a different sound feature for each theft warning area, and each warning sound identification part recognizes only the specific alarm sound which is output by the self-ringing type theft prevention tag arranged in a corresponding theft warning area, and detects that a theft act event occurs in the corresponding theft warning area when recognizing the specific alarm sound.SELECTED DRAWING: Figure 5
