The art in that article really is unimpressive. No pics of the cameras, no details of the screen used to ID, no pics of anything at all that is interesting and enhances the article. Just shows that even 8 years ago web journalism sucked
I feel like multimedia players come and go (unlike the stability of say the <img> element), so it’s entirely probable that the site looked different 8 years ago, and a migration or few later the video content was lost.
NYPD does this with their marked cars too (standard patrol cars with ALPR rig attached fore and aft). Ostensibly it's the meter maids expediting detection of parking violations but the data obviously has other uses.
