The security system prevents theft of articles from an enclosure having a lockable access opening. Using RFID technology, a transponder periodically scans the enclosed display area to interrogate RFID tags associated with each of the articles within the enclosure. Access to the enclosure is controlled by an electronically activated retrofit lock associated with the access opening. Biometric technology is used to identify an individual attempting to access the enclosure and to determine whether the identified individual is authorized to access the enclosure. If the individual is authorized, the identity of the authorized individual, the identity of an article removed from the enclosure, and the time that the article was removed from the enclosure are recorded. A POS/inventory control system notes the sale of the removed article. A security alert signal is generated if the removed article is not sold or returned to the enclosure within a given time period after the article was removed from the enclosure. Images of the area proximate the enclosure may be captured by a closed circuit video camera and stored.

The present invention involves a system for automatically screening closed circuit television (CCTV) cameras for large and small scale security systems, as used for example in parking garages. The system includes six primary software elements, each of which performs a unique function within the operation of the security system to provide intelligent camera selection for operators, resulting in a marked decrease of operator fatigue in a CCTV system. Real-time image analysis of video data is performed wherein a single pass of a video frame produces a terrain map which contains parameters indicating the content of the video. Based on the parameters of the terrain map, the system is able to make decisions about which camera an operator should view based on the presence and activity of vehicles and pedestrians, furthermore, discriminating vehicle traffic from pedestrian traffic. The system is compatible with existing CCTV (closed circuit television) systems and is comprised of modular elements to facilitate integration and upgrades.
