Parameters Description
SVC
Select the checkbox to enable SVC function. Select 1 or 2 from the drop-
down list on the right. The default setup is 1, there is no scaled
encoding.
SVC refers to the scaled video coding. It can split the video stream to
basic stream and enhanced scale.
Encode mode
Set video encode mode.
●
H.264: It is a highly compressed video encoding or encoding
standard. At the same video quality, it has increased the
compression rate by 2X compared with the MPEG-2.
●
H.265: It is a new video encode standard coming after H.264. It has
improved the complicated relationship among bit stream, encode
quality, latch and algorithm on the previous standard. It can get the
best encoding.
Resolution
Set video resolution. The higher the resolution is, the better the video
quality is.
Different series products support different resolutions. See the actual
page for detailed information.
FPS
It is to set the frame amount displayed at each second. The higher the
frame rate is, the more vivid and fluent the video is.
Stream mode
Set video bit stream control mode.
●
CBR: The bit stream changes slightly. The bit stream is near the
value you set here.
●
VBR: The bit stream might change according to the environment.
Quality
Set video quality. It includes low, middle, high.
It is null when the stream mode is CBR.
Bitrate
Set video bitrate.
●
Main stream: In the Bit Rate list, select a value or enter a customized
value to change the image quality. The bigger the value is, the
better the image will become.
●
Sub stream: In CBR mode, the bit stream changes around the value
you set. In VBR mode, it changes according to the bit stream value,
but its max value is near the specified value.
I frame interval
Set the P frame amount between two I frames. Usually we recommend it
is the 2X of the frame rate.
Step 5 Enable Event Video Quality and set FPS and stream mode.
Event video quality is for main stream only.
Step 6 Click Save.
