Parameter Description
Compression
Select the encoding mode.
●
H.265: Main profile encoding. This setting is recommended.
●
H.264H: High profile encoding. Low bit stream with high
definition.
●
H.264: Main profile encoding.
●
H.264B: Baseline profile encoding. This mode requires higher
bit stream compared with other modes for the same
definition.
Resolution
Select resolution for the video.
The maximum video resolution might be different depending on
your device model.
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.
