Hi sorry for late reply!
This is the best resource for realtime mobile camera locations in Holland:
http://www.bnr.nl/nl-nu/flitsers/
I consider it "the best" because most people call or sms to this radio station and provide up to date info about the mobile camera locations AND they also call/sms to inform the radio the mobile camera has been removed after a few hours.
It's by far the most popular resource. It's freely available and there is also a WAP/Mobile version of the site:
http://www.bnr.nl/mobile/flitser/
It's probably a lot easier to fetch the info from this link.
2nd best:
flitsservice.nl (click on "Flitsers & Files")
the wap/mobile version:
http://wap.flitsservice.com/wap.aspx
wap/mobile version viewable in normal browsers:
http://imode.flitsservice.com/imode2.aspx
or another alternative:
http://www.flitsers.nl/
Not sure if it is allowed to use the data. On the flitsservice.nl site, they specifically mention you can use this link to view speedcamera locations on your own website:
http://flitsservice.com/flitsservice/me ... /link.aspx
But if I click that link it simply brings me to the homepage of this website..
I really hope this is useful.
For the fixed camera's (speed & redlight) there is an excellent site for Netherlands/Benelux providing POIs for all navigation systems:
http://flitspaal.nl
Goal of that site is that you can download the POI file in the specific format suitable for your navigation system (like navman, tomtom, garmin and the common format is CSV) and upload it to your navigation device.
So this data is free for everyone.
