Swann DVR-1590 Series Instruction Manual page 19

Record: Mainstream (720p model)
CBR:
This is the default method of control that your DVR will use to re-
cord video. If you have cameras placed in high traffic areas, CBR is the
recommended control method. As the bitrate is fixed, the image quality
will be consistent throughout the entire recording. This will assist when
identifying people or objects.
VBR:
If you have cameras placed in low traffic areas, VBR is the recom-
mended control method. As the bitrate is variable, your DVR can use a
lower bitrate if there is little to no movement detected. This will result in
a lower recording size as well as a lower bandwidth requirement.
When choosing VBR, you can select the recording quality that will define
the variable bitrate used. You can select from worst to best.
Bitrate Mode:
You have the choice of selecting a predefined or user-de-
fined bitrate. For most instances, the default selection will be suitable.

Bitrate:
The amount of data that your DVR will use to record video. The
higher the bitrate, the more space each recording will consume on the
hard drive. The default bitrate is 2048Kbps. Change the bitrate if you're
having issues streaming to your mobile device via the HomeSafe View
app (when selecting "Mainstream" in Live mode to view your cameras).
Decreasing this will consume less bandwidth when streaming.
Audio: Click the checkbox if you have an audio source connected to the
DVR's audio input(s) (for 8 channel models, this option is only available
on camera input 1).
Please note:
Selecting the appropriate recording settings is de-
pendent on camera location, lighting conditions and the level of
quality required. A certain level of experimentation is recommended to
select the best settings for your needs.
