This DVR converts analog NTSC or PAL video to digital images and records them on a hard disk drive. Using a hard disk drive allows you to access recorded video almost instantaneously; there is no need to rewind tape. The technology also allows you to view recorded video while the DVR continues recording video. Digitally recorded video has several advantages over analog video recorded on tape. There is no need to adjust tracking. You can freeze frames, fast forward, fast reverse, slow forward, and slow reverse without image streaking or tearing. Digital video can be indexed by time or events, and you can instantly view video after selecting the time or event. Your DVR can be set up for event or time-lapse recording. You can define times to record, and the schedule can change for different days of the week and for user-defined holidays. The DVR can be set to alert you when the hard disk drive is full, or it can be set to record over the oldest video when the disk is full. Your DVR uses a proprietary encryption scheme making it nearly impossible to alter video. You can view video and control your DVR remotely by connecting via Ethernet. There is a USB port you can use to upgrade the system or copy video clips to external hard disk, CD-RW drives, or flash drives. 24
