Vulcan - but the system with speedcameras and red light cameras has been in place for at least 10 years here in the UK and works very simple: you pass the camera at higher speed than a speed limit, it takes two pictures, there are lines on the road to prove that you were moving fast and you get a ticket through the mail.
If it was not you driving - it's your problem to come up with the name. If you don't - you are in charge of the vehicle and you get a fixed fine + penalty points. You can go to court to argue your case but you chances there are slim to none and then you pick up the court fees as well.
They are primarily there to slow the traffic down in the areas where it's necessary and they do just that. The are not hidden - out there in plain view. If you are dumb enough to get caught by one - surely you were "driving without due care and attention" (an offence in itself)? If you know you were speeding - why would you argue you were not?
I agree it might get trickier with the red lights though but if it stops some dumbo to drive into a side of your car...
