Backup Camera Cables

[freewill2008]

I hafta pull some wires the length of our bus behind the overheads and
would like to pull in what I need for a camera at the same time. (This
bus didn't have a factory camera installed.)

What kind of cabling do I need? I'm sitting on a bunch of coaxial RG62
cable with BNC connectors. Is that impedance close enough for a 35'
run? Also, does the camera need a 12v power cable also?

Thanks in advance.
