I initially agreed, but then I had the thought that this would lead to people just knowing which lights have camera and being extra careful around those, while freely running the lights elsewhere.

Imagine if we had a problem where a bunch of people were burglarizing houses, so we decided to declare specific enforcement zones where the cops were really on top of preventing burglaries. Would people be less likely to burgle, or would they just do their burglaries elsewhere?

Instead, town-wide, it should be made known with prominent signs that traffic enforcement is in use, and ideally the cameras should move around, so that people can't simply adjust their behavior to compensate. In other words, your idea, but put that sign on every intersection.

That’s exactly what I’ve witnessed in places that have cameras, regardless of if there are signs.
