[Connection Template]
Select the type of your network connection. Unless you select
Customized
, this option will
automatically bring up the recommended video resolution, frame rate, bandwidth and GOP
size.
[Video Signal Type]
Select the codec type, resolution and frame rate. The default codec is
MJPEG
. Choose H.264
or MJPEG for the main stream/sub stream. The supported resolutions are listed blow:
Video Resolution
4:3
1280 x 960, 640 x 480, 320 x 240
16.9
1280 x 720, 640 x 360, 448 x 252
Main Stream
5:4
1280 x 1024, 640 x 512, 320 x 256
4:3
640 x 480, 320 x 240
16.9
640 x 360, 448 x 252
Sub Stream
5:4
640 x 512, 320 x 256
[Bandwidth Management]
When using the H.264 codec, it is possible to configure the bitrate settings to control
bandwidth usage.
VBR (Variable Bitrate):
The quality of the video stream is kept as constant as possible at
the cost of a varying bitrate. The bandwidth is much more efficiently used than a
comparable CBR. Set the image quality to one of the 5 standards:
Standard
,
Fair
,
Good
,
Great
and
Excellent
.
Maximal Bit Rate:
When the system bitrate exceeds the specified Maximal Bit Rate, the
system will automatically lower its bitrate so as not to exceed it. Select one of the bitrates
from the drop-down list or select
Auto
if you do not want to enable this function. The
default value is 6 MB
CBR (Constant Bitrate):
CBR is used to achieve a specific bitrate by varying the quality
of the stream. The bitrates available for selection depend on the image resolution.
[GOP Structure and Length]
Set the maximum number of seconds between every key frame.
