I can take a single wide-angle of the scene in low-res (including all the objects of low interest like sky and trees). Then I can take a camera and zoom to the area where trucks drive into a warehouse to get the driver and the license plate and a wide-angle picture of the side of the truck. But you do not have to record the low interest items in high-resolution.
