Direct camera in side-scroller

Hi,
Im looking for a blueprint or any suggestions on directing camera posiotion in side-scroller game. "Inside" is a good example. Camera on one rail smoothely moves WITH the character left-right but I can regulate position, angle and FOV to show important elements. It doesnt have to be scripted so camera “thinks” and follows these elements. Once its set itll be fixed.
I would appreciate Your help. Thank You.
