I'm thinking of streaming games and wanted a cam, is there a way to turn my iPad 2 into a webcam?
I don't know about IOS, but on android, you can install lots of apps which allow you to connect your phone to your computer trough wifi, as a wireless webcam. I am using this, you can google for something similar for IOS. Things like ManyCam are great for capturing these kinds of wireless webcam streams.
Looks like an app here called AirCam should do the trick. Sorry, I'm not an iOS user myself so I can't say for sure how well it'll work.
