The problem is you can think it's for the 12V supply and put the wires into a Wago connector (thinking that is what you're supposed to do).

I was a little disappointed in the "How to Configure Your Camera" section this year. There was a picture of the power distribution board labeled "Camera Power Feed...", which is great that there's a picture, but there were 3 power feeds in the picture (5 if you include the power sources fed via breakers). How is a rookie team to know that it's the 5V source vs the 12V source vs the breaker fed source? They're all in the picture. An arrow photo-shopped into the picture pointing to the proper power source would have been helpful (or a note clarifying that it's the source laveled "5V").

I know that the control system drawings were clearly labeled to show which power source feeds the camera, but just following the "Getting started" document I can see how someone would try to feed the camera from the wrong source.
