The Telegraph just published a story about a study done by research in the UK who examined 44 studies done on the effectiveness of CCTV and found that the vast majority agreed that CCTV was generally ineffective at preventing crime. The only instance where CCTV was moderately effective was in parking lots, preventing some vehicle crimes. But that effectiveness was also found to be greater when accompanied by increased lighting and guards.

This study has specific importance to the UK because Britain has the largest public-funded CCTV network in the world, and British lawmakers stand to lose both public support and funding for CCTV if studies continue to find surveillance cameras ineffective at deterring crime.
