An Analysis on the Effect of Crime Prevention CCTV by Local Government

다국어 초록 (Multilingual Abstract)

This study analyzed the reduction in five major crimes (murder, robbery, theft, violence, and sexual violence) owing to the effects of crime prevention CCTVs. The data used for the analysis were statistics of crime prevention CCTV data and five major crimes reported in local governments for 5 years (2015–2019). The effect was verified by correlation analysis and variance analysis method.
According to the analysis results, first, the reduction effect differed for each type of crime. This was high in the order of violence < robbery < five major crimes < theft. However, the result of sexual violence was not significant.
Second, the reduction effect differed depending on the number of the crime prevention CCTVs. Based on the number of crime prevention CCTVs per 10,000 population, the effective reduction rate was observed to be 36 units for theft and 60 units for the five major crimes/robbery/violence. Indeed, the effect might vary depending on the appropriateness of the installation site, such as a crime-prone area.
This study is meaningful as the first study to analyze the effect of crime prevention CCTVs using the data of the entire country. The results of this study are expected to be utilized by local governments when establishing policies to prevent crimes and improve local safety indices by installing crime prevention CCTVs.
