Claim Text:
1. A computer-implemented method of intelligently measuring actual video data retention in a video surveillance infrastructure by an independent audit of video data, where incoming video data streams received from a plurality of video capturing devices are processed by a video management software (VMS) application running on a video processing server, and processed outgoing video data streams are directed to one or more storage devices, the method comprising: for each video data path, obtaining usage profile of video data on a storage device for a particular time period; obtaining usage profile of video data on the storage device for a time period immediately preceding the particular time period; calculating by a computer processor, an actual time period of retention of video data using a difference between the usage profiles of the successive time periods; comparing the actual time period of retention with a desired time period of retention associated with an individual video data stream from a video capturing device to a storage device to calculate a key performance indicator (KPI); using the KPI to determine quality of video data retention in the video surveillance infrastructure.
