Don't know. That's why I asked

Quite possibly. Outside of Short Brackland the next cam is cam 10 (Google "Bury St Edmunds CCTV" and click the What Do They Know pdf link) but that camera is also catching the flow of traffic from Well Street, so there would be countless cars to check. It's also possible to turn off before that cam and head up Church Row. If you do that, you don't pass any other cctv cameras on the main system (again see the PDF and use google maps to verify the one way systems).
Basically, beyond Short Brackland, the number of possible potential vehicles and traffic rises massively because the cams on any route after Short Brack could be picking up traffic from a myriad of other side streets/main roads.
Someone local with a sat nav might want to try a couple of tests, pointing your sat nav to MacDonalds Buttermarket, or Hughes Electrical, or Short Brackland, and see what routes it suggests. We may get some clues as to what a potential driver was heading for, and whether they got sent to slightly the wrong place? I'm not sure how reliable using google street directions is, cos it may differ to TomTom's suggestions?
Still, if you try a "directions" from your home to Short Brackland, you can see it typically sends you in from the North roundabout and you bypass main CCTV system.
That said, Google directions DOES send you down a little road "Cadney Ln" and there does appear to be a Curry's Service Centre with private CCTV attached to it, and that would be a good CCTV to check. Mind you... it's got a telegraph pole in front of the camera that MIGHT be looking at Cadney Ln (the cam on left side of building, not the one on front of it that appears to be looking at the doorway/path). And again they could just be dummy cctv cameras (they certainly look like dummies). Would be good to find out if Curry's Service Centre (or whatever it is now) turned over their CCTV footage, cos a car coming down Cadney Ln around 3.15am is potentially the vehicle that picked up Corrie!
