So I joined Google+ today. Also got an iPad Mini for Christmas. What I want to do is use my iPad Mini as a camera so that I can join a few folks to talk about sports (Don't we all). The problem is, there's no instructions as to how to do this. I do not want to buy a camera right now, too expensive. I know that Facetime is involved, but I don't know how to connect with it. How do I set up my iPad Mini as a camera so that I can use it for Google Hangouts?
