Ps3 move do I need a second eye camera for 2 player mode or does one camera pick up the 2 motion controllers?

I have the ps3 and move starter pack. Just wondering if I want 2 people to play a game at the same time, eg in sports champions, do I just need to buy another motion controller? Will the one camera be able to track both players or do I need a second camera as well for it to work?Ps3 move do I need a second eye camera for 2 player mode or does one camera pick up the 2 motion controllers?One camera, buddy! You can have up to like 16 controllers at once, since it can produce virtually every color imaginable.
