Figure 4-14 Encode
Table 4-12 Description of encode parameters
Parameter Description
Sub Stream
Click to enable sub stream, it is enabled by default.
You can enable multiple sub streams simultaneously.
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
.
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 be only be set as
CBR
when
Encode Mode
is
set as
MJPEG
.
