Does Technology Really ‘Secure’ a City?

It’s time we prove the true impact of video surveillance on crime prevention

It is past time for a professional, statistically defensible risk analysis study of video surveillance technology and its impact. Does it reduce violent crime? Does it mitigate the risk of property crimes? Ultimately, is it worth the expense to acquire, deploy, and maintain?

These are important security questions which I was surprised to find unanswered. How do security professionals justify these expansive and expensive solutions without an ability to outline the risk reductions they effect? If we want ‘secure cities,’ these are questions we must answer.

Editor’s Note: Secured Cities brings together the experts who can help answer the questions that Mr. McCumber poses, with real-life examples and strategies. Check out for information about upcoming conferences.
