The biggest issue with speed cameras is a matter of cost/revenue.
The inital cost will be recovered with no problem, however, comfort levels of revenue after that cost will not be very high, given that when/if people stop speeding, the speed cameras no longer create income.
Therefore, they are only as cost effective as the amount of income they could generate immediately, but then not so much.

Sorry to be OT, but there is a lot more than that to consider.
If you actually get people to stop speeding, you effectively reduce the average speed of circulation from the current situation. On highways, for each reduction of 1 mph in average speed, you get a reduction of roughly 4% in accidents.
That is a great deal less people dying on our roads each years, people who will continue work and pay taxes. A greater number of people not being sent to the hospital as a result of a crash. Finally over a million people each year who do not have to deal with the productivity losses associated with an accident.
There are huge benefits for everyone to be had if people were actually driving the speed limit.
