The Fit screen function allows displaying a Surveillance window by default so that it occupies all the available space on the screen (full screen). The default zoom step for full screen display is calculated automatically as a minimum zoom value that allows filling the available screen space with the Surveillance windows.

To enable the Fit screen function for a specific Surveillance window, display the digital zoom controller (see Digital video zoom), click the  button on it, and save changes when exiting editing mode.

To enable the Fit screen function for all Surveillance windows on the layout, open the context menu and select Image size adjustment.

Now when a user switches to this layout, the video in the Surveillance window is displayed at the calculated minimum necessary step of digital zoom and the Surveillance window occupies all available space.
