This individual is either drunk / High or Distracted always.. Seems like last month was almost the same thing.

Interesting, I have never try to get details after the video has been recorded will try to see if I can come up with something. Yea I hope this does not happen again or like you said might have to setup a camera just to capture the face if can..Have you tired exporting the clip and increasing the Gamma or brightness to see if you can retreive any facial features from the close up clip you have? It might be worth a try as the police might recognise him if they can see a face.
Alternaitively if this is happening very regularly, you could deliberately set one camera to over exposure / gain so as to capture his face.
