Configuring Preview Local
If there is no local screen in the current layout (such as remote full screen or split mode does not display
local), the local thumbnail image cannot be viewed when adjusting the local camera, so the camera cannot
be accurately adjusted. If you enable preview local, when there is no local screen in the current layout,
the local small window is superimposed in the lower right corner of the screen when you adjust the local
camera. After no PTZ operation within five seconds, the local thumbnail image disappears.

thumbnail image when you
