Max Key Frame Interval: Configure the interval frames between two key frames,
ranging 1 ~ 250. Suggest applying the default value 75. The larger the value is, the
less fluctuation of the stream there will be and the worse the image will be, vice
versa.
*
Smart Encoding: Enabling “Smart Encoding” will reduce the frame rate. When
enabling Smart Encoding under low bit rate, the image quality will be improved.
Please select according to actual request. It takes effect after reboot.
*Stream Smoothing Factor: Drag the slide bar or enter a number to configure stream
smoothing factor. The smaller the value is, the clearer the video stream will be; the
larger the value is, the smoother the stream transmission will be.
Note:
The parameter of Image Quality is enabled only when “VBR” is selected and it
will remain “Middle” when “CBR” is selected.
Different encoding formats have different levels of encoding complexity.
The higher the Encoding Complexity is, the more the stream will be compressed.
In this way it will relieve bandwidth restriction somehow, but meanwhile it will
also occupy the CPU resource of more devices. Suggest using the default level.
After
enabling
Smart Encoding, some functions will be disabled, such as ROI
and Max Key Frame Interval.

ROI
ROI means Region of Interest. The camera only encodes specific area of interest to
improve image quality of this area while at the cost of decreasing the image quality
outside this area. It not only ensures the image quality of ROI area, but also reduces the
bit rate. Configuration steps are as follows:
1) Go to
Settings > Camera > Video > ROI
;
Picture 6-18 ROI
2)
Select “Enable” to enable ROI function;
3) Click "
Edit
" and drag an area from the left window as the clipping area. Select
encoding grade from the dropdown list. Click “
