With the H.265 codec in an optimal scenario and when the Dynamic Intra frame and the Smart Stream
function are applied, an 80% of bandwidth saving can be achieved compared with using H.264 without
enabling these bandwidth-saving features.
►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.
