Crime reduction became one of the major issues of the modern society. In order to achieve public re-assurance, police forces all over the world are undertaking actions to involve citizens in crime preven-tion through community policing. In parallel, technological platforms were deployed in order to share crime-related information with the public and to support the development of problem-solving strate-gies. However, the impact of these initiatives in terms of crime reduction and perception has not been sufficiently investigated yet. Furthermore, up to now, no previous studies compared the effectiveness between the traditional approach of preventive patrolling and technology-based crime prevention so-lutions. Therefore, we present a study design which aims at assessing the effectiveness of the two aforementioned crime prevention measures. The goal is to evaluate and compare their effects over the local criminal activity and citizen’s safety perception measured by Fear of Crime (FOC) and Per-ceived Risk of Victimization (PRV) constructs. Preliminary results show a rather low level of FOC across the whole sample, paired by a high level of PRV. Furthermore, potential explanatory back-ground factors for the previous constructs have been identified and will be explored in future work.
