Unfortunately, this type of video is far too common.
On the plus side, one could argue that at least this video gives fundamental evidence - where exactly did it occur, how many people where there, how many approached them, how long it took, what happened first, how long did it take, etc.
On the other, there's a number of obvious problems - the huge tree in the middle that blocks most of the view, the very high mounting position, the camera seemingly try to do too many things - is it monitoring the store entrance/exit? is it monitoring the street? is it monitoring the corner outside the store? evidently, the designer/user wanted to do all 3 and in the process made it hard to see any details.
