Comparing with Smart Stream II, Smart Stream III has two more configurable options: Smart Q , and
Smart FPS .
NOTE:
• Smart codec: Smart codec 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 codec is preferred.
- Auto tracking : The Auto mode configures the whole screen into the non-interested
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 configure 3 ROI windows (Region of Interest,
with Foreground quality) on the screen. Areas not included in any ROI windows
will be considered as the non-interested areas. The details in the ROI areas will
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.
