Open Question: What does the two different camping sites mean for V Festival?

I'm considering buying a ticket for V Festival next year but I don't understand the camping situation. Are they in different places, and do they mean you have access to different acts/arenas?. Or are they just seperate campsites and you both have access to the same arenas? Help!!!
