Abstract
A surveillance system which can store and replay information which is not generated contemporaneously. In some point-of-sale systems, the behavioral events occur before the transaction data is generated. The present system asynchronously records the video signals corresponding to the behavioral events and the transaction data. Upon playback, the transaction data is matched up with the behavioral event being replayed from the video tape.
