Effects of Closed-Circuit Television on Crime 

 - Thousand Oaks :  Sage Publications,  May 2003 
<br/><br/> This article reports on the findings of a systematic review - incorporating meta-analytic techniques - of the avaliable research evidence on the effects of closedcircuit television (CCTV) on crime in public space. A number of targeted and comprehensive searches of the published researchers produced twenty-two CCTV evaluations that met our criteria for inclusion in this review. CCTV had a significant desirable effect on crime, althought the overall reduction in crime was a rather small 4 percent. All nine studies showing evidence of a desirable effect of CCTV on crime were carried out in the United Kingdom. Conversely, the other nine studies showing no evidence of any desirable effect of CCTV on crime included all five North American studies. CCTV was most effective in reducing crime in car parks. It had no effect on violent crimes but had a significant desirable effect on vehicle crimes
