Claim:
1. A method for validating asset movement comprising: defining at least one virtual tripwire for at least one video camera of a video surveillance system that monitors a defined area of interest through which a plurality of assets are conveyed, wherein the at least one virtual tripwire visually defines a boundary within a view field of the at least one video camera, and wherein the plurality of assets are identified by an attached radio-frequency identification (RFID) tag; detecting movement of an asset through a virtual tripwire by a video camera, wherein said movement of the asset through the virtual tripwire is considered as a potential misdirection; notifying an asset management system of the detected potential misdirection of the asset, wherein said notification comprises at least a location of the video camera having detected the potential misdirection and a time of the detected movement; obtaining RFID data for the detected asset by the asset management system from a RFID handling system, wherein said RFID handling system monitors the area of interest; determining a validity of the movement of the asset through the virtual tripwire by the asset management system based upon the RFID data and an asset movement specification, wherein said asset movement specification defines pathing rules for the plurality of assets and virtual tripwires; and when the movement of the asset is determined to be invalid, generating a record of suspect movement data to document the movement of the asset through the virtual tripwire, wherein obtaining RFID data for the asset further comprises: requesting the RFID data from the RFID handling system, wherein said request comprises at least the location of the video camera having detected the potential misdirection; determining of a RFID reader closest to the location of the video camera having detected the potential misdirection by the RFID handling system; activating of the RFID reader determined to be closest to the video camera by the RFID handling system; capturing of the RFID data contained within the RFID tag attached to the asset by the activated RFID reader; and conveying the captured RFID data to the asset management system.
