UTV rear view camera

After installing doors on my mule I cannot see my rear view mirrors. SO is there a rear view camera that works as mirrors? Not a back up cam. I want to see full time.
just

Our local John Deere sell a aftermarket cab cam that may be worth looking into.

Any of those back up cameras will work. It's just depends on where you get your power from. Most power off the back up lights so they only come on in reverse. You could power off the battery to a switch and turn it on when you want it or off of the ignition.
