Red light-triggered intersection cameras and photo radar aren't even the same thing in the context of what we're talking about. The infrastructure for intersection cameras is fixed, it's clearly signed, and not hidden with the goal of being predatory. I have some reservations about the speed limits of intersections where they've enabled speed-on-green for the cameras to begin with, but that's a different matter.
Though on that subject, you could get the same benefit by increasing the amount of time the entire intersection stays red before allowing the next direction to proceed, likely without the accompanying increase in rear-end collisions that intersection cameras cause.
