“…For all other evaluations, the average, largest, and smallest effects were identical. The high variance of the random effects model led to the counterintuitive finding of the smallest effect meta-analysis having a larger OR than the largest effect meta-analysis.12 One evaluation was conducted at a city hospital(Gill & Spriggs, 2005), one was conducted in a school/university setting(Lim & Wilcox, 2017), two were conducted across entire cities but were unable to be disaggregated to smaller settings(Kim, 2008;, and one was conducted in undisclosed mixed environments(Lim, Kim, Eck, & Kim, 2016).13 Some studies reported the presence of flashing lights on top of CCTV cameras. Rather than consider this a separate category, we classified these studies as "signage" given that they related to a similar causal mechanism (i.e., visible confirmation of the CCTV camera presence).…”

Research Summary We report on the findings of an updated systematic review and meta‐analysis of the effects of closed‐circuit television (CCTV) surveillance cameras on crime. The findings show that CCTV is associated with a significant and modest decrease in crime. The largest and most consistent effects of CCTV were observed in car parks. The results of the analysis also demonstrated evidence of significant crime reductions within other settings, particularly residential areas. CCTV schemes incorporating active monitoring generated larger effect sizes than did passive systems. Schemes deploying multiple interventions alongside CCTV generated larger effect sizes than did schemes deploying single or no other interventions alongside CCTV. Policy Implications The results of this systematic review—based on 40 years of evaluation research—lend support for the continued use of CCTV to prevent crime as well as reveal a greater understanding of some of the key mechanisms of effective use. Of particular salience is the continued need for CCTV to be narrowly targeted on vehicle crimes and property crime and not be deployed as a “stand‐alone” crime prevention measure. As CCTV surveillance continues to expand its reach in both public and private space and evolve with new technology, policy will benefit from high‐quality evaluations of outcomes and implementation.

“…This confirmed Wilson and Sutton's (2003) findings on the crime prevention effects of CCTV. Lim et al (2013) also found that CCTV's effect on crime prevention depends on the characteristics of the location. Kang et al (2009) used crime reduction and people's awareness of crime in areas after the placement of CCTV to explain the effects of CCTV installation.…”

“…However, such guidelines cannot be implemented in Korea, where public access to criminal records is difficult. Lim et al (2013) verified that while the use of CCTV does not significantly reduce serious offenses, it does reduce crimes on public streets. This confirmed Wilson and Sutton's (2003) findings on the crime prevention effects of CCTV.…”

This paper proposes a placement model for closed-circuit television (CCTV) cameras to effectively monitor criminal activity on pedestrian streets in student safety zones in South Korea. Although pedestrian streets around schools are potential crime sites, the legal management of and supervisory responsibility for these areas are ill-defined. The increasing demand for public supervision in student safety zones requires the effective control of high-cost CCTV systems. The rational choice perspective and routine activity approach can be used to explain attackers' preferences for criminal activities and the accompanying situational characteristics. Surveillance conditions differ depending on the pedestrian flow and immediate environment. The spatial properties derived from the pedestrian street network affect pedestrian flow. In addition, visibility of the physical environment affects natural surveillance and mechanical surveillance. Quantitative research is presented on the needs for surveillance considering these properties, and a placement model for public CCTV cameras is proposed that uses a genetic algorithm. Following an analysis of surveillance conditions, the model provides information describing the placement and mechanical operation of surveillance cameras. CCTV cameras are routinely installed in student safety zones; the proposed model should contribute to the effective planning and installation of these cameras.

“…The progress in surveillance technology has led to the development of Closed-Circuit Television (CCTV) systems in cities around the world. However, studies on the impact of CCTV cameras on the number of crime incidents do not provide an unambiguous answer [1]. Practitioners often emphasize the impact CCTV cameras can have both in terms of the ability to identify a criminal and as a prevention method that deters criminals [2,3].…”

“…Practitioners often emphasize the impact CCTV cameras can have both in terms of the ability to identify a criminal and as a prevention method that deters criminals [2,3]. Yet, a review of CCTV impact on crime reduction research by Lim et al [1] shows inconclusive findings. Although the effect is noticeable for vehicular crimes and parking lots, it is usually not significant for city centers and residential areas.…”

Progress in surveillance technology has led to the development of Closed-Circuit Television (CCTV) systems in cities around the world. Cameras are considered instrumental in crime reduction, yet existing research does not unambiguously answer the question whether installing them affects the number of crimes committed. The quasi-experimental method usually applied to evaluate CCTV systems’ effectiveness faces difficulties with data quantity and quality. Data quantity has a bearing on the number of crimes that can be conclusively inferred using the experimental procedure. Data quality affects the level of crime data aggregation. The lack of the exact location of a crime incident in the form of a street address or geographic coordinates hinders the selection procedure of experimental and control areas. In this paper we propose an innovative method of dealing with data limitations in a quasi-experimental study on the effectiveness of CCTV systems in Poland. As police data on crime incidents are geocoded onto a neighborhood or a street, we designed a method to overcome this drawback by applying similarity measures to time series and landscape metrics. The method makes it possible to determine experimental (test) and control areas which are necessary to conduct the study.
