You say power is live/neutral. Are you sure it's not DC?

The OP mentions power supplies for the cameras and modulators, so the
chances are it is DC rather than the mains...

If it's DC, then one of those supply wires will be the ground

And easy to check from the old layout, he wants the one that connected
to the screening boxes of the modulators.

Alternatively, is that audio wire really audio or could it be video
ground? Do you definitely have audio on those cameras?

Or it could be balanced video but unlikely from a cheap camera they
tend to just generate normal unbalanced 75ohm baseband video.
