They have become more sophisticated, and mobile. They now mount this camera in a van that moves every day, it is run by the Maryland Transportation Authority, not the State Police. It was raining hard the day they tagged me, and there was not a single person working that day. I was in the morning rush and was on my way to the BWI airport and the flow of traffic was all moving the same, but I got a ticket in the mail a few days later when I got home, charged with doing 67/55. The fine is $40 with no points and no entry on your driving record. If you want a court hearing you have to travel nearly 100 miles away, or pay the fine. A private corporation runs these cameras and splits with the state, though a MTA officer has signed the complaint attesting that this is a true record, etc. Wish I had thought of this first - buying a camera, computer and vehicle for the privilege of collecting $20 on just about every vehicle that drives by on I-95. What a deal.
