55.2-59 Rear Camera for Panel/Sub

[BBPanel]

I'd like to install a rear facing/backup camera on my Panel. However, I have barn doors and do not want to mount it on one of the doors. I'd like to mount the camera just above the drip rail but I don't how that placement would work to be effective. The only other location would be just above the bumper but I suspect that would be too low. Anyone on the board done this on a Sub/Panel and how did it work out?
