Abstract: This study aims to address the conditional nature of the effectiveness of open-street CCTV (Closed Circuit Television).Therefore, this study examined the differences in the effects of CCTV between daytime crime and nighttime crime, between weekday crime and weekend crime, and across specific-crime offenses.Also, this study examined crime reduction effects of CCTV depending on CCTV site type (e.g., downtown location, business district, school/university location, or residential area).For the analyses, this study used HLM (hierarchical linear modeling) with 84 repeated measures across 34 camera locations in Cincinnati, OH and Z-tests in order to compare coefficients.During the first stage of analysis, the findings showed that open-street CCTV did not have crime reduction effects on daytime crime, nighttime crime, weekday crime, weekend crime, robbery, auto theft, and theft from auto, whereas it had significant crime reduction effects on assault and burglary.During the second stage of analysis, location type was considered, and results showed that the crime reduction effects of open-street CCTVs during weekends varied depending on implementation sites.The reduction effects were greater in residential areas in comparison to the effects in business districts and downtown areas.The crime reduction effects of open-street CCTVs for robbery also varied depending on implementation site type.The reduction effects were greater in residential areas in comparison to business districts.The final stage of analysis examined diffusion of benefits versus displacement effects.The findings supported the hypothesis that diffusion of benefits effects were greater than displacement effects.Specifically, WDQ analyses showed that when CCTV had crime reduction effects in target areas, diffusion of benefits rather than displacement occurred for daytime crime, nighttime crime, weekday crime, weekend crime, assault, robbery, and
