METHOD AND SYSTEM FOR CATEGORIZED EVENT RECORDING OF IMAGES IN MULTIPLE RESOLUTION LEVELS

摘要

A method includes compressing digital data of video images to a second resolution level and storing the digital data at a plurality of resolution levels. The plurality of resolution levels include a first resolution level and the second resolution level.. The first resolution level is greater than the second resolution level. The method also includes receiving a category selection, responsive to the received category selection, determining whether the digital data stored at at least the first resolution level is needed, responsive to a determination that the digital data stored at at least the first resolution level is not needed, performing one of the following: discarding the digital data determined to not be needed; and flagging the digital data determined to not be needed to be discarded later.
