Radical ideas?

[In The Ten Ring]

Hey ya'll,

I've been thinking about this since I started working on my truck last month. I'd like to install both a forward AND rearward-mounted video camera. I have a hard time parallel parking even a modern car and in this truck it's really is hard to know when I've pulled up or backed up far enough.

What would it take to get both (say toss in a still picture ability and video recording also) cameras to feed to one output display mounted to the driver's side visor? That way I could flip it down to see exactly how close I'm coming to the car in front or in back and still only have to drop my eyes down to see out the windshied.

What say you?
