UK we have had speed cameras for ages. There was a trend for people to either spray paint the lens or even firebomb the camera. So they had to put in a second (video) camera mounted as high as possible to protect the first camera, quite amusing that a safety camera has to be kept safe by another safety cameras, its cameras all the way down.

Personally I think speed cameras that monitor a fixed point are pretty dumb unless that fixed point is an accident black spot such as outside a school or a red light camera for dangerous set of traffic lights. Its far better to have average speed cameras for a large section of road but those are more costly as you need way more cameras to make them work outside of motorways as you need to cover all the junctions properly.

Latest cameras we have in testing can see if you do not have your seat belt done up or are using your phone. Just stopping people from using their phone has to be the biggest step forward we can make with modern road safety.

How about instead of speed cameras you change your road designs? People won't speed if they cannot speed safely.

Make your roads less wide. Add some curves, depending on required max speed, you make the curves larger or smaller. On lower speed roads, add obstacles to drive around.

There are many forms of traffic management that don't require speeding cameras but then again, speeding cameras are for making the government money, not for traffic safety

People vandalize speed cameras

Toronto city council decided last week that it will install "larger, more visible and clearer" signs to warn drivers where automated speed enforcement cameras are located in the city.

"HEY VANDALS! THE SPEED CAMERAS ARE OVER HERE!"

I don't really care that much either way for speed cameras. They work in a very limited fashion, but they punish the poor the most, and the money goes to cops.

At the end of the day speed cameras are a solution to a problem that doesn't need to exist. We are failing to use technology available to us for basically no reason - we already know how to slow people and calm traffic without any kind of economic/punitive incentive.

Replace speed cameras with road diets and other geometric choices that restrict traffic speed without relying on drivers following rules (they don't)
