I haven't seen any of the Furrion night (infrared) images, or other cameras for that matter.
I wasn't expecting a lot out of the night version, but decided to check tonight. It is total darkness out where the RV is parked right now.
This is the EXACT same image as above, but in the dark:
Not the greatest, but it is dark. I didn't try with the backup lights on. Should get better...
