In a column on CNN.com and republished with permission on SecurityInfoWatch.com titled "Spy Cameras Won't Make Us Safer", security expert Bruce Schneier railed against the value of surveillance cameras. While SecurityInfoWatch.com is not sure when Schneier became an expert on physical security (his background is data encryption), he does make some very good points about lack of maintenance on cameras, lack of monitoring, and the fact that cameras are expensive. But he goes on to say that "the funds now spent on CCTV cameras would be far better spent on hiring and training police officers." As a student of the policing and security industries, I think Bruce's point is accurate in some cases, but not in every instance. Many times I've been told by police chiefs and security managers that those cameras extend their manpower significantly, and that even if they had more officers they still wouldn't get the same forensic evidence that the cameras provide.

So, with Schneier's jab at video surveillance being passed around the industry, we called upon a few opinionated persons to respond. Interestingly, the general consensus was that Schneier was mostly right in his analysis even though he sensationalized the essay for mass consumer media purposes. Of course, the sensationalizing may have been done by CNN's producers, who have to make a column on video surveillance as interesting as Jessica Simpson (Simpson was the topic of a competing headline on CNN's site when the Schneier column ran). Our respondents generally thought that Schneier was on the right track but that his conclusion that we should get rid of cameras and purely spend money on staffing was off-base. Here's what they had to say in response to Schneier's column:

Pat Fiel, former security chief for Washington, D.C., Public Schools, now with ADT Security Services:

I'm a firm believe that surveillance cameras are very effective if used properly. The key to a successful implementation is effective planning, a proper assessment, good positioning and set-up, budgeting, monitoring, staffing, education and training. Sure, they might not have stopped the killing [that Schneier referenced], but the cameras did what they were supposed to do, which is to serve as a forensic tool. The cameras are a deterrent, and unfortunately we don't always have 24-hour monitoring of most cameras, but they still are providing value.
