The Camera Link-to function helps you link any camera to an object with auto-follow when the actor or prop moves. The camera view will stay with the linked object and keep it in view throughout its entire animation. Camera Look-at keeps the camera in it’s set position, but pivots the camera view to always look at the defined target object.
