Wait, is that click it and it goes into a camera mode, or another brick shows 'Live Footage' of the 'Camera' brick?
Because, if it's just clicking another brick, then yeah, 'SetPlayerCamera' should work fine.
However, if it's the 'Live Footage' one, i don't believe it would be very good, it would have to have a high FPS, which would no doubt lag in someway or another.
