ALPS vs Speed Cameras?

Hey Guys:

Thanks for all the helpful posts, they were really informative!
As far as poliscan use in Maryland, it's all over the state and in individual communities. They are mounted everywhere from on the front of parked jeeps and other vehicles in construction zones on major highways/interstates, right down to fixed permanent and semi-permanent cameras (roadside box) in neighborhoods and school zones.
