If there is a separate connection between video screen and earth, the Earth Link should
be broken. This usually occurs on copper-connected systems where all of the copper

If fiber optics or other indirect connections are used to get data and video to and from
the control room, then the Earth Link should be left intact, as long as it is the only
camera-end earth reference point.
