Abstract
A method and system for use in a computer controlled video surveillance system are disclosed for storing and retrieving data relating to information recorded on a video tape, thereby locating visual information recorded on a video tape. The system comprises means for recording visual information on a plurality of segments of a video tape, each of the segments being defined by a time at which its recording begins and a time at which its recording ends. Means are provided for recording a tape identification code on the plurality of segments of the video tape. A tape counter generates a tape count such that for each segment, a corresponding initial tape count is generated at the time when recording of that segment begins. The invention further comprises a database. Stored in the database is a log corresponding to the video tape. The log comprises a record relating to each segment. Each record contains searchable fields. One of the fields contains the initial tape counts corresponding to the segment to which the record relates. Means are provided for communicating the tape count to the database. The method has the following steps: generating an identification for identifying the tape; …
