If you are in a warehouse or a location without a drop ceiling the dome may make little sense. So in a setting where you have rafters you may want to mount bullet cameras with a bracket that can easily mount. If the ceilings are just way to high you may want to consider mounting it to a wall. But when mounting to a wall you have to make sure it's out of reach of someone that can tamper with it or you can wall mount some domes. For this you need to be careful because the brackets inside some domes will not swivel far enough to capture your desired shot.
