Hello there and friendly greetings!
So, if I got it right, I can add the ID of a camera I place on a custom monument I made and this will suffice, am I right?

Something like:

"Cameras": {
    "SPACENEEDLE01": true,
    "OILRIG2L6D": true,
    "OILRIG2L6C": true,
    "OILRIG2L6B": true,
    "OILRIG2L6A": true,
    "OILRIG2EXHAUST": true,​

This plugin was only designed for static cams, not player-placed cams. 

But if you are using rust edit to place them + marked static and whatnot then yes those would show up in the config generation.
