Annotation: This study examined the crime reduction effects of publicly funded closed-circuit television (CCTC) cameras in Philadelphia, PA using two evaluation techniques.
Abstract: The evaluation found that when serious and disorder offenses were considered together crime was reduced by 13 percent after the implementation of the closed-circuit television (CCTV) cameras while controlling for length of month, seasonal effects, and the unique temporal trends at each camera. Used as methods of monitoring public space for over two decades, CCTV seeks to reduce crime primarily by increasing the perception among potential offenders that there is an increased risk of detection and capture. Evaluation of these efforts to reduce crime has been mixed. Using Hierarchical Linear Modeling (HLM) and Weighted Displacement Quotient (WDQ) methodologies, this study explored serious crime, disorder, crime, and an all crime measure combining serious crime and disorder, with a multi-method spatio-temporal evaluation of 18 pilot CCTV cameras across 10 sites in Philadelphia, PA.
