Funny, I just posted this story a couple of days ago. I think it was from 2014. There was a lot of noise about this sort of tech and then it just went quiet. I really doubt this tech is going unused. I suspect something like this was used to track down the CEO killer recently(with a parallel constructed cover story).
they used the footage to solve some cartel murder by playing the footage in reverse to track the origin of the killers
