Hmmm.. food for thought...
We had some vans broken into outside our offices a while ago and the first thing the Police asked was whether we had CCTV. We had, and played the footage back only to watch half an hour of two hooded characters attempting to steal our vans. Average height, average weight, black clothes. Very useful.
Now if we'd had the CCTV cameras at a height that would have caught their faces instead of the tops of their hoods then that would have been useful....
So just think about that when installing CCTV cameras. Obviously don't put them somewhere reachable so that a savvy burglar can drop his jacket over the lens while he nicks your car, but equally if you can have a camera installed indoors (or hidden in a hedge...?) in a position that will capture something useful like their faces - then this is surely the way forward.
I know you might think that having a camera somewhere visible acts as a deterrent, but it clearly doesn't when a hoodie can hide a multitude of sins.
