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.
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 user defined holidays.
