you can download the whole database directly from autovelex for 10 euro/yr. but there are already
apps out there, so it's unclear what your added value is going to be.
OR, you can scrape this page
http://www.speedcamupdates.it/
it only took me a minute to find and download the speed cameras coordinates in my area (lontano
da italia). you set bounds, so the bigger the bounds, the more cameras you get. if you only want italy,
you can work that out with a map. but the whole world is available. the downloads are in xml, so that's
annoying, but there are tools to deal with that.
here are some around rome:
