Digital video
recorder (DVR) is a device that records video
without videotape to a hard drive-based digital
storage medium. The term includes stand-alone
set-top boxes and software for personal computers
which enables video capture and playback to and
from disk.
The DVR provides a convenient, if limited, replacement
for the multiplexer + VCR combination and provides
non-linear access to recorded material usually
selected by camera ID, time and date. The consistency
of quality of recorded material will in general
be higher than that obtained with analogue tape
although the actual quality achieved may or may
not be better, depending on the compression algorithm
and individual configuration. |
|
In general more
programmable options for individual video stream
recording parameters, (picture resolution, number
of frames per second, trigger options, start/stop
times etc), are available, but a DVR is only useful
where the analogue cameras are all cabled back
to the DVR’s location. Competent DVRs now
feature UDP (CAT 5) network ports so that the
device can be provided with an IP address and
thereby become accessible over an Ethernet network.
It uses a single IP address to access thousands
of cameras without loading your network. It's
easy to set up and use. |
