2.4.2 MPEG4
If you selected ‘MPEG4’ as the video encoding format of this IP camera, you
can specify the parameters of MPEG4 video encoder here.
The descriptions of every setting in this menu will be given below:
Item Description
Video Resolution Specify video resolution of MPEG4 video encoder. Available
options are VGA, QVGA and QQVGA resolution. VGA
resolution provides more details than QVGA/QQVGA, but
requires more network bandwidth.
Video Quality
Specify video quality. There are two video quality types: CBR
(Constant Bit Rate), and VBR (Variable Bit Rate):
CBR: The video bit rate is fixed, you can select a bit rate from
dropdown menu. Higher bit rate means better video quality. But
if your network bandwidth is limited, select a lower bit rate will
help.
VBR: Video bit rate is variable based on the video content
being transferred. There’re 5 levels of setting from ‘Lowest’ to
‘Highest’. Select ‘Lowest’ will lower video quality and save
network bandwidth; if a better video quality is required, select
‘High’ or ‘Highest’.
Video Frame
Rate
Specify video refresh rate of MPEG4 video encoder. Higher
video refresh rate provides more details about motion, but
requires more network bandwidth.
CAUTION: Choosing a low frame rate will save bandwidth, but
may not be able to capture every motion if the object that IP
camera points to is moving too fast.
Click ‘Apply’ to save settings and make the new settings take effect.
