They can also only go 5m, 3m and 3m, respectively, before interfacing to a computer (which then uses ethernet to go somewhere else anyway).
Ethernet makes sense if you consider that images are going straight from the camera to the control room (which is hundreds of feet away, and possibly parked outside in a truck), and that there's likely already network infrastructure (switches and cabling) in place for dozens of other reasons.
