I've written an app that is (at this stage) meant for people living in the Netherlands.

With this app named Laura you can see all speeding cameras It is a speeding camera detector. It detects police radars and laser guns. Again: this app only works properly if you are living in the Netherlands, sorry about this.

Dutch:
Met Laura zie je alle flitsers, flits-meldingen en ad hoc radar controles van de politie.
