Table 4-4 Description of encode parameters
Parameter Description
Sub Stream Click to enable sub stream, it is enabled by default.
Compression
Select encode mode.
●
H.264B
: Baseline profile encode mode. It requires smaller
bandwidth.
●
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.265 : Main profile encode mode. Compared with H.264, it
requires smaller bandwidth.
Resolution
The resolution of the video. The higher the value is, the clearer the
image will be, but the bigger the bandwidth will be required.
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 be only be set as CBR when Encode Mode
is set as MJPEG .
Reference Bit Rate
The most suitable bit rate value range recommended to user
according to the defined resolution and frame rate.
