摘要：The current research investigated whether open-street CCTV (Closed Circuit Television) system reduces crime or not. Crime data and open-street CCTV data from a Korean city were used to find the answer to the research question. The research designated all crime, serious crime, and disorder crime variables as response variables, and camera, length of month, trend, and seasonal effect variables as predictor variables. Multiple linear regression and Possion regression model were used for analyzing the data. Appropriate model was developed for each response variables after checking various methods. The findings showed that open-street CCTV had mixed effects on crime depending on crime types.
