Across Western Canada there are tens of thousands of CCTV cameras protecting valuable business assets that do nothing more than record what's going on. In some cases these cameras are watched by an expensive on-site security guard who really does try to stay awake watching a static CCTV monitor for activity.
Most CCTV security systems don’t have a human watching them live and are either naively used as a visual deterrent, or people only view the recorded CCTV footage retrospectively, and get to watch the break-in after the fact, after the criminal has gone, and the damage has been done.
