Make another camera in your scene, along with the first one (we'll call these cameras A and B). In your script, store references to both Camera objects A and B, and make A follow player A, and B follow player B (or whatever it is). When you switch, set one Camera component to be enabled, and one to be disabled (and vice versa).
