Don't aim your camera to view the horizon and leave a BIG blind area immediately behind you. I drive a school bus and we don't have cameras at all. When and if we need to back up, remember the catch phrase "GOAL" for "get out and look".
Have you even looked at the mounting bracket for your current camera? I relocated our camera so that I can JUST see the bumper at the very bottom of the monitor. I don't need to see anymore that that. It allows that I can line my trailer hitch up solo. It also allows me to see as much of my TOAD as I need. Any further our directly behind me.........we can see what we need to see with the two side mirrors.
Like the sticker on the back of semi trucks with trailers.......
"If you can't see my mirrors, I can't see you."
