Title: THEFT PREVENTION DEVICE AND THEFT PREVENTION SYSTEM
Abstract:
Provided are a theft prevention device and a theft prevention system which are capable of reliably detecting theft by being installed in a simple installation manner. The theft prevention device is provided with: a receiving unit 12 for receiving radio waves of a predetermined frequency; and a microcomputer (control unit) 18 for determining whether an object is in a position at which radio waves of a predetermined frequency cannot be detected by the receiving unit 12. The microcomputer (control unit) 18 performs an alarm operation when it is determined that an object is in a position where monitoring radio waves WW of a predetermined frequency cannot be detected by the receiving unit 12. Therefore, it is sufficient to mount the theft prevention device 10 to an object to be managed MO such as a product or the like to be monitored, and it is unnecessary for a cable to be extended from a sensor unit mounted on a product or the like.
