Parameter Description
Encoding Strategy
Select the encoding strategy as needed.
●
General: Disable smart codec.
●
Smart Codec: Enable smart codec to improve video compressibility
and save storage space. It is applicable to static scenes.
●
AI Code: When the bandwidth and storage space are restricted, the
camera will select the encoding strategy with lower bit rate to save
storage space. It is applicable to dynamic scenes.
After AI codec is enabled,
Bit Rate Type is CBR , and it cannot be
changed. Comparing with general mode, AI codec has lower bite
rate. This function is only available on cameras with AI functions.
After smart codec and AI codec are enabled, the camera would stop
supporting the third stream, ROI, and smart event detection, and the
actual interface shall prevail.
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.
Video Clip
This function is available only for sub stream 2 of some select models.
●
Main stream
1. Select the resolution as needed, and click next to
Resolution .
The Area interface is displayed.
2. Clip the image on the
Area
interface, and then click
Save
.
View the clipped video on Live interface.
●
Sub stream 2
1. Select Video Clip , and click .
The Area interface is displayed.
2. View the clipped video on
Live
interface (only the live interface
of sub stream 2 displays the clipped area).
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 .
Quality
This parameter can be configured only when the Bit Rate Type is set as
VBR .
The better the quality is, the larger the bandwidth will be requested.
