Hallways and Camera Angles

[WhyteSpyder]

I was wondering if anyone could tell me how to make triggers that would make the camera follow a Player's Hero from behind on map initilization. Furthermore I'd like some help knowing how I can make it so that when the hero turns the corner of a hallway that the camera will rotate so you can see down the hallway, but still follow the hero afterwards. Almost like a Resident Evil 1 kind of camera system. Much appreciated to anyone who can help.

Is it like you look from the back of that Hero and when it turns, the camera follows to look at where the Hero is looking at? It may be quite laggy for a multiplayer game.
