Wow, that is really a good idea!
I would like to get one installed on my toilet with the video display on the wall in front of me. That would making backing onto it a hell of a lot easier! Also, I could inspect for the lingering dingle berries without having to do the courtesy wipe!
Personally, I think these cameras would do even more good for Americans if installed in every bathroom too. What government agency can we contact for this?
