Exchange Streaming Type
NVR allows users to setup the dual streaming configurations in camera
parameter page if cameras support dual stream. It is suggested stream 1 is
set for higher resolution and stream 2 for lower resolution, which helps
users to choose the proper streaming in live view with intuitive control.
To switch the different streaming, users can select the channel in live view
page and right click the mouse to show the list.
When "Optimization" is enable, streaming type is adjusted automatically in
different display modes.
When "Optimization" is disabled, users can manually adjust streaming type,
which will be memorized in different display modes.
