Operation Manual
Parameter
Description
Click
to enable smart codec to improve video compressibility
and save storage space.
Smart Codec
After smart codec is enabled, the device would stop supporting the
third bit stream, ROI, and smart event detection.
Output Mode
You can select from Single Stream or Flex Stream.
Resolution
The resolution of the video. The higher the value is, the clearer the
image will be, but the bigger the required bandwidth will be.
Frame Rate (FPS)
The number of frames in one second of video. The higher the value is,
the clearer and smoother the video will be.
The bit rate control type during video data transmission. You can
select bit rate type from:
●CBR (Constant Bit Rate): The bit rate changes a little and keeps
close to the defined bit rate value.
●VBR (Variable Bit Rate): The bit rate changes as monitoring scene
changes.
Bit Rate Type
●ABR (Average Bit Rate): The bit rate takes into account bandwidth
savings and image quality improvement.
●The Bit Rate Type can only be set as CBR when Encode Mode is
set as MJPEG.
●The Bit Rate Type can be set as ABR only when Encoding
Strategy is set as AI Coding.
This parameter can be configured only when the Bit Rate Type is set
as VBR.
Quality
The better the quality is, but the bigger the required bandwidth will
be.
Reference Bit Rate
The most suitable bit rate value range recommended to user
according to the defined resolution and frame rate.
This parameter can be configured only when the Bit Rate Type is set
as VBR or ABR.
Supports for custom max bit rate.
Max Bit Rate
You can select the value of the Max Bit Rate according to the
Reference Bit Rate value. The bit rate then changes as monitoring
scene changes, but the max bit rate keeps close to the defined value.
This parameter can be configured only when the Bit Rate Type is set
as CBR.
Bit Rate
Supports for custom bit rate.
You can select bit rate value according to actual condition.
