Parameter Description
Compression
Select encode mode.
●
H.264 : Main profile encode mode. Compared with H.264B, it
requires smaller bandwidth.
●
H.264H : High profile encode mode. Compared with H.264, it
requires smaller bandwidth.
●
H.264B : Baseline profile encode mode. It requires smaller
bandwidth.
●
H.265 : Main profile encode mode. Compared with H.264, it
requires smaller bandwidth.
●
MJPEG : When under this mode, the image requires high bit rate
value to ensure clarity, you are recommended to set the Bit Rate
value to the biggest value in the Reference Bit Rate .
Smart Codec
Click to enable smart codec to improve video compressibility
and save storage space.
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 frame in one second of video. The higher the value is,
the clearer and smoother the video will be.
Bit Rate Type
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.
The Bit Rate Type can only be set as CBR when Encode Mode is set
as
MJPEG
.
Quality
This parameter can be configured only when the Bit Rate Type is set
as
VBR
.
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.
Max Bit Rate
This parameter can be configured only when the Bit Rate Type is set
as VBR .
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.
