Recent decades have seen the emergence of closed-circuit television (CCTV) surveillance as a situational crime prevention strategy used around the world. This study seeks to establish the effect of CCTVs on urban crime/ violence in Kampala city. Specifically this study establishes the effect of CCTV installation on urban crime/violence reduction, and clearance by police. The study employs a quasi-experimental design basing on the Uganda Police Force crime data/statistics. The study compares changes in urban crime/violence and crime clearance of locations in Kampala city where CCTVs have been installed, with comparable locations in the city without cameras. Crime data/statistics for 2016-2017—before CCTVs were installed, and that of 2019-2020 after cameras were installed will be used to determine the effect. Odds ratio (OR) are used to measure effect size, while regression analysis is employed to explore how the effects of CCTVs differ by location, seasonality, and during the course of the day.
