Navigation through Local Files is very similar to navigation through the Camera archive, except:
•Items are not synchronized, therefore Sync is always disabled)
•Files are not live, therefore Live is always disabled
•Timeline does not display colored markers for recorded or motion regions
• and
buttons jump to the beginning or end of a file
All other operations (seek, play, pause, ff/rew, etc.) are described in details in "Navigating through Archive and Live".
Note: If a layout contains both cameras and local files, the cameras are played back synchronously, but the local files play back independently.
