Abstract: A railway for an overhead camera surveillance system comprises a track comprising a plurality of flexible track segments joined end-to-end, the track being configured to define at least one rail along which at least one motorized camera carriage suspended therefrom is moveable.

Abstract: An auditing method comprises controlling at least one camera device at least at one facility to cause the at least one camera to acquire at least one image of a designated region within the at least one facility; at a remote location, comparing the acquired at least one image of the designated region to a desired standard; and completing an audit report based on the results of the comparing.

Abstract: A method of inhibiting article theft at a location employing at least one-self checkout station and an antitheft security system, each article carrying at least one antitheft label, comprises reading information from an article, sensing at least one physical parameter of the article, retrieving article parameter information from a database based on the read identification information, comparing the sensed the at least one physical parameter with the retrieved article parameter information and deactivating each antitheft security label carried by the article if the sensed at least one physical parameter generally corresponds with the article parameter information.

Abstract: An electronic article surveillance system capable of reliable operation at high frequencies such as about 8 MHz, has an arrangement of transmitter and receiver antennas each lying in a flat, horizontal plane in substantial alignment with each other, with the receiver antenna positioned at the floor of a passageway at an interrogation zone and the transmitter antenna positioned overhead. Each antenna takes the form of a pair of parallel-connected, coplanar loops with the transmitter-connected loops being positioned such that electrical current flows around each loop in parallel in the same direction (a ++ configuration) and in the receiver antenna electrical current flows around each loop in parallel in mutually opposite directions (a +- configuration). The antennas are approximately of the same size and overall configuration, and they are positioned in substantial alignment so that the currents induced in the receiver antenna by the field from the transmitter antenna will effectively cancel.
