That's a distinct possibility. I went on a "speed awareness course" fairly recently where we found out that in the Thames Valley Police area, there were only some 13 cameras (as far as I remember) for the 300 fixed camera sites. The cameras are swapped from site to site fairly frequently. There are also quite a few "mobile" cameras which do indeed move round every day, covering multiple sites per day. Some of these are camera vans, others, cameras on a tripod manned by the Police. Integral GPS would improve the conviction rate I'm sure.
