• Smart stream: Smart stream effectively reduces the quality of the whole or the non-
interested areas on a screen and therefore reduces the bandwidth consumed.

You can manually specify the video quality for the foreground and the background areas.
Select an operation mode if Smart stream is preferred.
- Auto tracking: The Auto mode congures the whole screen into the background area.
The video quality of part of the screen returns to normal when one or more objects
move in that area. The remainder of the screen where there are no moving objects
(no pixel changes) will still be transmitted in low-quality format.
- Manual: The Manual mode allows you to congure 3 ROI windows (Region of Interest,
the Foreground areas) on the screen. Areas not included in any ROI windows will
be considered as the Background areas. The details in the ROI areas will always
be transmitted in a higher-quality video format.
As illustrated below, the upper screen may contain little details of your interest,
while the sidewalk on the lower screen is included in an ROI window.
