I don't see much point in debating the merits or otherwise of security cameras. We've all heard good and bad stories about them. That's even without the distinction between having something from Maplins that John Logie Baird would think is rubbish, versus some of the high end stuff that can see a fox on my back garden in total darkness or can read number plates half way up the cul-de-sac. Ever seen the output from an HD+ pinhole camera in a domestic PIR?
Nevertheless, the weakest link in any chain is the one you can see outside the house at ground level and disable with the edge of something blunt after you've pulled off the plastic capping.
Even in the worst case you'd be amazed how much more interested the police are in any form of crime if they have hi-res images available. At least, that's what my mate found out when someone levered down the door of his van like a can opener to steal his tools. Good job he had a van vault inside.
