How Do Police Speed Vans Operate ?

Obviously there's a man in the back with a frikkin laser but other than that how do they operate ?

Is it on all the time recording and when he see's large number's he makes a note or is it all recorded and gone through back at the station ?

Just wondering as I went past one yesterday at 70 which on the dual carriage way would be fine, but I was towing a trailer which he wouldn't have seen until I went past him.

Only 10 over so not the end of the world - just got me wondering how they operate.

They just leave it running.

Then someone later runs through 8hrs of film ?

That doesn't see very productive.
