Try this:
Create a locator...
Create | Locator...
Then name it....CameraHinge is good. Then in the Outliner, select your CameraHinge and then your camera, then in your hotbox select Constrain | Orient. Your camera should change it's orientation when it turns along your path...
I hope this works....I haven't done it that much and this is from memory.
