Parameter Description
Compression
Select the encoding mode.
H.265: Main prole encoding. This setting is recommended.
H.264H: High prole encoding. Low bit stream with high denition.
H.264: Main prole encoding.
H.264B: Baseline prole encoding. This mode requires higher bit
stream compared with other modes for the same denition.
Resolution
Select resolution for the video.
The maximum video resolution might be dierent depending on your
device model.
Frame Rate (FPS)
Congure 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
dened 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.
ABR (average bit rate): When selecting ABR, you need to congure
Max Bit Rate and ABR.
The connected camera needs to support the average bit rare.
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
dened value; for variable stream, the bit rate changes along with
the image but the maximum value still stays near the dened value.
