Technical Overview
In addition to replacing both a time-lapse VCR and a multiplexer in a security installation, your
DVR has many features that make it much more powerful and easier to use than even the most
advanced VCR.
The 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.
