“…In the other two sites diffusion of benefits have been established; namely WDQ's 0.43 and 0.51. These last two values are close to the values that Caplan et al [26] and Park et al [14] calculated in the studies. A limitation of this study is that in a number of experimental fields a very low frequency (monthly) of serious crime.…”

Research Article Introduction A Systematic Review of Displacement and Diffusion Effects of Crime Through Formal SurveillanceFrom the nineties, CCTV deployed in public areas [1]. Since then, several studies have calculated that in London at least hang half a million video cameras [1]. This is roughly equivalent to an average of one camera for every fifteen people. Not only in London was from the nineties to see an increase in the number of cameras, but also in major cities in countries such as France and Spain [2]. Camera surveillance is an example of formal surveillance, as well as for police patrols and alarm systems [3,4]. According Weisburd et al. [5], there is increasing evidence that various forms of formal surveillance impact in crime in and around the area of the intervention. For example, the risk that crime and nuisance move to areas with no intervention, in the sense of formal surveillance is present.The objective of formal surveillance is deterring offenders and potential offenders. This formal surveillance is accomplished through the use of actors who are primarily responsible for security, such as police officers and other security personnel. The introduction of technology, the above-mentioned actors helped or even replaced. For this reason, it is also to be placed under the term formal surveillance [6,7]. According to the rational choice theory [8] are offenders by committing formal surveillance deter crime. This theory states that because offenders and potential offenders weigh the costs and benefits of committing crime. The presence of formal surveillance increases the risk of getting caught. This increased risk of being caught, the costs are also increased, making the cost-benefit analysis is less favorable.Another criminological theory consistent with the deterrent effect of formal surveillance is routine activity theory of Cohen & Felson [9]. According to routine activity theory, the probability that a crime is committed greater when meet the following three conditions: lack of oversight, a motivated offender and suitable target [10]. Sets the theory implied that if (formal) supervision is present in a public space, this deters offenders and potential offenders. With a public space, as in the article of Welsh Mudge & Farrington [11], a space meant that one can make use of unencumbered and accessible for basically every citizen. The above criminological theories as Bernasco et al. [12] compatible with the theory of situational crime prevention Clarke [13]. This approach to prevention focuses on the potential target of a perpetrator. This target should be protected by formal surveillance which increases the probability of detection of the perpetrator.However itself, a number of situations occur when formal surveillance increases in a particular area, to ensure that formal surveillance not always lead to a reduction in overall crime. These situations indicate that crime in different ways can be moved as a result of an increase in formal surveillance in an area [14]. Repetto TA [15] outlined five...

“…CCTV is frequently applied as a practical method of crime prevention during construction planning processes. Park et al (2012) noted that CCTV installation is effective at preventing crime in Korea. They argued that, when installing CCTVs, their number and location must be determined scientifically, and an in-depth analysis of crime patterns must first be conducted.…”

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.
