The cameras are 100 percent not on the mainline FedEx aircraft. They are not on our ATR aircraft either.
The system is called the Apareo Vision 1000 or something like that. If you go to the manufacturer's website there is a pretty good (disgusting) description of what it does.
Pretty sure the lenses on these things will magically become smudged.....or otherwise. Nobody wants these things in the aircraft.
Someone mentioned on freightpilots.com that neodymium magnets might be a good thing to start carrying around in your flight bag.
