Resolution The DVR system supports various resolutions, which you can
select from a dropdown list.
Note The selection is different for each DVR series. The HQA
DVRs can automatically detect a connected 720p or
1080p camera’s configured resolution (as 720p or
1080p) But you must manually configure the resolution
(960H or below) for analog cameras, and 1080p HQA
cameras that are in SD mode.
Frame Rate PAL: 1 to 25 fps
NTSC: 1 to 30 fps
Bit Rate Type Select either CBR or VBR.
Bit Rate Main Stream: Select a bit rate to change the video quality.
The larger the bit rate, the better the video quality. We

selected resolution.
Sub Stream: In DBR, the bit rate is the maximum value. For
dynamic video, the DVR system will decrease the frame rate
or video quality to maintain the bit rate. The value is null for
VBR mode.

frame rate you have set.
