you to set different frame rates for motion detection record and
alarm record.
Video encode mode.
H.264: Main Profile encode mode.
H.264H: High Profile encode mode.
H.264B: Baseline Profile encode mode.
H.265: Main Profile encode mode.
MJPEG: System needs high bit streams to guarantee
video definition. Use the recommended max bit stream
value to get the better video effect.
This function is to reduce bit streams.
Note
Some series products support smart codec function.
After changing smart code, please reboot network
camera and some network camera functions (such as
IVS, ROI, SVC, lobby mode and etc.) becomes null.
Please think twice before the operation.
The resolution here refers to the capability of the network
camera.
The video frame amount displayed in each second. The higher
the frame rate is, the clearer and more fluent the video is. The
frame rate may vary depending on the resolution.
Main stream: You can set bit rate here to change video
quality. The large the bit rate is, the better the quality is.
Please refer to recommend bit rate for the detailed
information.
Extra stream: In CBR, the bit rate here is the max value.
In dynamic video, system needs to low frame rate or
video quality to guarantee the value. The value is null in
VBR mode.
System supports two types: CBR and VBR.
Main stream: It is to set frame rate to change video
quality. The higher the frame rate is, the better the video
quality is. The referenced bit rate is the recommended
value.
Sub stream: In CBR mode, the bit stream is near the
specified value. In VBR mode, the video quality changes
according to the bit stream value. But its max value is
near the specified value. Reference bit rate: The
reference bit rate depends on the resolution and frame
rate you set.
Recommended bit rate value according to the resolution and
frame rate you have set.
Here you can set the P frame amount between two I frames. The
value ranges from 1 to 150. Default value is 50.
Recommended value is frame rate *2.
