Starry box + Civil police car with camera

Hello guys, for a few days I have always had the following question through my head on which I could not find an answer so far in this special case. I recently made a longer motorcycle tour for several days. On the first day (it was already dark) I got caught a stationary star box, that this is half as wild is actually already clear to me, because it was still an older model which did not flash from behind. – How much I was too fast i ch not – The next day a few kilometers further on, however, two civilian police officers filmed and pulled me out. Was within a village and clearly too fast ( 3 points plus driving ban for a month are sure). Fortunately, I am not dependent on the appearance for the work…. But now to the actual question: can it happen in such cases or are possibly known cases, in which the pictures of the rigid box are somehow compared with the video and thus I find out I would be happy to hear your opinions to make it easier for me to wait for the mail a little bit…
