I have a number of cameras which are both hidden and disabled, but they still show up in the UI3 display. Is there any way of hiding them?
I'm running v5.5.7.9 x64
In UI3, the behavior is supposed to mirror the BI console by default. So start by checking if it is set as expected in the console.
That aside, you can override the behavior in UI3 by right-clicking (or long pressing) on a camera in the layout and choosing "Group Settings". For hidden and/or disabled cameras, choose "Force ON".
