Camp rule clarification

[douglas1999]

If you die at a camp you are holding solo, is it forfeit? Or do you have a certain window to get back to the camp before somebody else can take it?

I took over a camp somebody died at, and they showed back up like 4-5 min later and said it's camped. I didn't argue the point and gave it back, but it did make me wonder what the actual rule is?
