Why can’t I playback all channels at once?<br />
The <strong>DVR</strong> only has so much processing power, and we’ve<br />
configured it so that it has more resources dedicated to<br />
recording than to playback.<br />
While you’re playing back footage, the <strong>DVR</strong> continues<br />
to monitor and record normally. Recording from four or<br />
eight channels at once (depending on your model) is so<br />
resource intensive that playback is limited to two channels<br />
simultaneously in realtime.<br />
If you do require playback of more channels than the <strong>DVR</strong> is<br />
capable of at once, then we suggest using the Backup process<br />
to copy information off the <strong>DVR</strong> and then playing it back via<br />
the remote interface on a PC.<br />
When we say that it can “playback so many channels at near<br />
real-time”, this doesn’t mean things will be in slow motion.<br />
Rather, the action will unfold at normal speed, but be<br />
represented by half the number of frames per second (12.5fps/<br />
PAL or 15fps/NTSC).<br />
