Technical Overview
Your DVR can replace both a time-lapse VCR and a multiplexer in a security installation. However,
it has many features that make it much more powerful and easier to use than even the most
advanced VCR.
The DVR converts analog 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.
The DVR can be set up to alert you when the hard disk drive is full, or it can be set up to record over
the oldest video once the disk is full.
Your DVR uses a proprietary encryption scheme making it nearly impossible to alter video.
You can view live video, search image, and control your DVR remotely by connecting via modem
or Ethernet. There is a USB port that can used to back up the clip file video to USB-IDE hard disk
drives, USB CD-RW drives or flash drives.
