Step 2 Select a channel and then congure parameters.
The parameters for main stream and sub stream are dierent. Some models support three
streams: main stream, sub stream 1, sub stream 2.
Table 5-20 Audio/video parameters
Parameter Description
Coding Strategy
●
General : Use general coding strategy.
●
Smart Codec : Enable the smart codec function. This function can
reduce the video bit stream for non-important recorded video to
maximize the storage space.
●
AI Codec : Enable the AI codec function. This function can reduce
the camera code stream, network transmission pressure, and hard
drive storage space without aecting the image quality.
Type
Select the recording type for main stream from General , Motion
(motion detection), or Alarm.
Compression
Select the encoding mode.
●
H.265: Main prole encoding. This setting is recommended.
●
H.264H: High prole encoding. Low bit stream with high denition.
●
H.264: Main prole encoding.
●
H.264B: Baseline prole encoding. This mode requires higher bit
stream compared with other modes for the same denition.
Resolution
Select resolution for the video.
The maximum video resolution might be dierent depending on your
device model.
Frame Rate (FPS)
Congure the frames per second for the video. The higher the value is,
the clearer and smoother the image will become. Frame rate changes
along with the resolution.
Generally, in PAL format, you can select the value from 1 through 25; in
NTSC format, you can select the value from 1 through 30. However, the
actual range of frame rate that you can select depends on the capability
of the Device.
Bit Rate Type
●
CBR (constant bit rate): The bit rate changes slightly around the
dened value. We recommended selecting CBR when there might
be only small changes in the monitoring environment.
●
VBR (variable bit rate): The bit rate changes with monitoring scenes.
Select variable stream when there might be big changes in the
monitoring environment.
Quality
The bigger the value is, the better the image will become.
This parameter is available if you select VBR as Bit Rate Type.
