Abstract
A system and method for securing premises by distinguishing between authorized and unauthorized removal of articles from the premises via an approach within the premises to an exit door (38). Each article is secured by a passive security device (50) which in an article-securing state will be detected upon the article entering the approach and in a non-securing state will not be wirelessly detected upon the article entering the approach. A detector (40), having a detection transmitter and a receiver, wirelessly detects attempted unauthorized removal of a secured article. A register (36) registers authorized removal of a secured article. An unsecuring transmitter (52) is controlled by the register to wirelessly transmit to a passive security device of a secured article whose authorized removal has been registered in the register, an unsecuring signal which unsecures the secured article by changing the passive security device from the article-securing state to the non-securing state.
