All correct. However, be aware that there is a new breed of "safety camera". It's small (very small), portable, attaches easily to crash barriers but can be placed almost anywhere, and some are omnidirectional. Almost impossible to see until it's far too late. They aren't that common yet and are still under trial.
In Spain they also use helicopters (spectacular waste of resources IMHO) so be careful on a clear day. Helicopters are mostly used during the main migration days (July, Aug and national BH's).
Top Tip:
Wherever possible avoid autoroutes, motorways and mainline "N" roads (some lesser ones are OK). Use the back roads. Not only are they far more interesting, less populated and more fun but they will rarely, if ever, have any traffic cameras or police on them. The caveat being that sometimes they wait at the entrance and exit of villages but, if like me, you always go through built up areas with the respect they deserve (keeps them biker friendly too) then you won't have anything to worry about.
