Abstract

A shoplifting system includes a first and second post-like housings positioned in a store on opposite sides of the doorway. The first housing includes an electronic receiver for receiving a wireless signal transmitted by a hand-held transmitter unit that is actuatable by a store employee who notices shoplifting activity by a shopper. The receiver causes actuating of an alarm device which issues an audible alarm sound in response to a signal received from the hand-held transmitter unit. The second housing is a "dummy" housing containing no detection circuitry. However, the second housing and first housing each have an appearance which suggests that both housings contain detection circuits that cooperate to detect the presence of detectable tags attached to products on sale in the store. A warning sign is placed on one of the housings.

Claims

1. A shoplifting alarm/deterent system comprising in combination:

(a) a first pedestal-like housing means positioned in a store adjacent to one side of an exit of the store;

(b) a second pedestal-like housing means in the store positioned adjacent to an opposite side of the exit, said second pedestal-like housing means having an appearance substantially similar to the appearance of said first pedestal-like housing means;

(c) means for wirelessly transmitting a first signal indicating detection by an employee of shoplifting activity by a would-be shoplifter, said transmitting means including manually actuatable switching means for causing said transmitting means to transmit said first signal;

(d) receiving means concealed in said second pedestal-like housing means for receiving said first signal and producing an alarm actuating signal in response to said first signal; and

(e) alarm means responsive to said alarm actuating signal for producing an audible alarm sound.

2. The shoplifting alarm system of claim 1 wherein the store has garments on sale, said shoplifting alarm system including dummy tags attached to respective ones of said garments for suggesting to shoplifters that the dummy tags are detectable by an electronic detection device.

3. The shoplifting alarm system of claim 1 further including a warning sign indicating that the store is electronically protected against shoplifting for deterring shoplifters.

4. The shoplifting alarm system of claim 1 further including alarm lights which are actuated in response to said alarm actuating signal.

5. The shoplifting alarm system of claim 1 and wherein said alarm means and said lights are respectively disposed in and on said second pedestal-like housing means.

6. The shoplifting alarm system of claim 1 further including a permanent actuating switch connected by means of a conductor to actuate said alarm means.

7. A method of deterring shoplifting activity in a store and producing an alarm signal in response to detecting of shoplifting, said method comprising the steps of:

(a) providing an external appearance on a pedestal-like housing to cause said external appearance to be similar to the appearance of other known housings used in other stores and known by shoplifters to contain detecting apparatus that physically detects detection tags on merchandise carried past said other known housings;

(b) concealing a receiver for receiving and detecting wireless signals in said pedestal-like housing;

(c) placing said dummy pedestal-like housing adjacent to an exit of said store, whereby the similarity of said pedestal-like housing to said known housings suggests to would-be shoplifters that said pedestal-like housing contains detecting apparatus that can detect unauthorized removal of merchandise through the exit;

(d) visual detection by an employee of said store, of shoplifting of a merchandise item by a shoplifter;

(e) manual actuation by said employee, of a hand-held wireless transmitter to cause said transmitter to transmit said wireless signal to said receiver;

(f) producing said alarm signal, by means of said receiver, in response to said wireless signal; and

(g) actuating an alarm device in response to said alarm signal to indicate the presence of the shoplifter in the store.

8. The method of claim 7 including the steps of placing dummy tags on garments on sale in the store.

9. The method of claim 7 including the steps of placing warning signs in the store indicating that the store is electrically protected against shoplifting.
