The Digital Video Recorder (DVR) system records high resolution digital images to a hard disk drive (HDD) and eliminates the requirement of maintaining VHS tapes. Since the video images are stored digitally, the image quality will not degrade overtime, as would a VHS tape when recorded over multiple times. The time saving intelligent search capabilities of a DVR will enable the user to locate the desired video clips via user defined parameters (camera, time, date, etc.) vs. Fast Forward and Rewind functions of a VCR.
