Step 2 Configure encode parameters.
Table 4-11 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
: It includes
H.264B
(baseline profile encode mode),
H.264
(main profile encode mode) and
H.264H
(high profile
encode mode).
Under the same image quality, the bandwidth of the three
decreases in turn.
●
H.265
: Main profile encode mode. Compared with H.264, it
requires smaller bandwidth.
●
MJPEG
: Under this mode, the image requires high bit rate to
ensure clarity, you are recommended to set the
Bit Rate
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.
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.
