To enforce speed limits enough to provide an inducement to drivers to reduce speeds.
Are cameras more effective at reducing speeds?
objective evidence: (Probably to be dismissed as book learning...)

Hey Forest, perhaps you'd like to meet some trees?
How does it help slow traffic down when you don't find out about it for months? What's more effective in impacting driving practices: a marked car in plain sight or an unmarked van?
Beyond that, the only reason for this is to raise revenues. That's it.
Worse: it is unconstitutional. THAT is my problem with it.
You cannot reasonably defend yourself when you have NO IDEA you did something wrong for weeks. Why is that so hard to understand?
MAIN RESULTS:
Thirty five studies met the inclusion criteria. Compared with controls, the relative reduction in average speed ranged from 1% to 15% and the reduction in proportion of vehicles speeding ranged from 14% to 65%. In the vicinity of camera sites, the pre/post reductions ranged from 8% to 49% for all crashes and 11% to 44% for fatal and serious injury crashes. Compared with controls, the relative improvement in pre/post injury crash proportions ranged from 8% to 50%.
AUTHORS' CONCLUSIONS:
Despite the methodological limitations and the variability in degree of signal to noise effect, the consistency of reported reductions in speed and crash outcomes across all studies show that speed cameras are a worthwhile intervention for reducing the number of road traffic injuries and deaths. However, whilst the the evidence base clearly demonstrates a positive direction in the effect, an overall magnitude of this effect is currently not deducible due to heterogeneity and lack of methodological rigour. More studies of a scientifically rigorous and homogenous nature are necessary, to provide the answer to the magnitude of effect.
Bold added because it's NOT CONCLUSIVE!
Further, do you know if these were mobile, undercover cameras? That's what I was "shot" with. How effective are those? Does the survey say? No, it does not.
So, thanks for posting something that may or may not apply and says of itself that it is not conclusive.
I think the main reason people complain about speed cameras is that they get caught...
Really, well, thanks for your opinion, even though it's contra what I said and makes no sense at all. The problem is that you don't know you sped, and therefore cannot defend yourself in court. When a cop lights you up, you look at your speedometer. When a camera takes a picture of you, you don't even know.
If safety was the issue, they would want to pull me over. What if speeding is only the tip of the iceberg? What if I'm high or drunk? A camera can do nothing about that and won't protect anyone else.
It's all about revenue. Anyone but a simpleton can understand that.
If you agree with the principle of speed limits, and agree that enforcement of the laws makes sense, how can you disagree with using the safest most efficient ways of enforcing the law?
I'd rather pay a skilled technician than a trained police offficer for a task as simplistic as whats required...And put the police officer on the street or in a public space where their [presence might deter other crimes. And where their training is useful.
See above. I know it's difficult, but strain your intellect for a change.

How can I possibly defend that? What if I'm innocent and they made it all up?
What if a uniformed officer makes it all up? How can you defend that?
Whats the difference other than the uniformed officers are less efficient?
I've explained that, in part.
Let's see. Why would someone speed?
In a hurry? Camera is fine.
Didn't see the sign? Camera is fine.
Just robbed a bank? Camera is useless.
Just ran over a child in a stolen car? Camera is useless.
Now, back to defense. It's easy. If a cop lies, you can go to court. If a tech lies, you can go to court, but . . . you (unless you are very rare) will have no recollection of the circumstances. How could you? You didn't even know you were ticketed.
You may think this is wonderful.
I think anyone who thinks it is wonderful wants a police state and has the IQ of a cactus.
