Parameter
Description
Frame Rate (FPS)
Configure the frames per second for the video. The higher the value is,
the clearer and smoother
the image will become. Frame rate changes
along with the resolution.
Generally, in PAL format, you can select the value from 1 through 25; in
NTSC format, you can select the value from 1 through 30. However, the
actual range of frame rate that you can select depends on the capability
of the Device.
Bit Rate Type
●
CBR (constant bit rate): The bit rate changes slightly around the
defined value. We recommended selecting CBR
when there might
be only small changes in the monitoring environment.
●
VBR (variable bit rate): The bit rate changes with monitoring
scenes. Select variable stream when there might be big changes in
the monitoring environment.
Quality
The bigger the value is, the better the image will become.
This parameter is available if you select VBR as Bit Rate Type.
I Frame Interval
The interval between two reference frames.
Bit Rate (Kb/S)
●
Main stream: The higher the value, the better the image quality.
●
Sub stream: For constant stream, the bit rate changes near the
defined value; for variable stream, the bit rate changes along with
the image but the maximum value still stays near the defined value.
