Presets are usually popular position points users set to easily travel from one position to another. For example, preset 1 can be your parking lot and preset 2 can be your front yard. By calling preset 1, your camera immediately turns to face your parking lot. This saves you a lot of time trying to pan your camera to your desired spot.
