Abstract(s)
Numa época marcada pela crescente aposta em tecnologias para a segurança urbana, os
sistemas de videovigilância (CCTV) têm-se destacado como ferramentas importantes na
prevenção da criminalidade. Apesar da disseminação global destes sistemas, persistem
dúvidas quanto à sua eficácia real, considerando que os estudos existentes apresentam
resultados contraditórios. Face à crescente preocupação social com a criminalidade
urbana em Cabo Verde, aliada ao sentimento de insegurança da população, o Governo
implementou o sistema de CCTV em várias ilhas, incluindo São Vicente. Este estudo tem
por objetivo avaliar especificamente o impacto da videovigilância urbana na prevenção
da criminalidade nesta ilha. Para o efeito, adotou-se uma metodologia quantitativa,
recorrendo a técnicas estatísticas descritivas e inferenciais na análise de dados criminais
participados à Polícia Nacional, abrangendo o período compreendido entre 2017 e 2024.
Contrariamente ao inicialmente previsto, os resultados indicam um aumento
estatisticamente significativo da criminalidade no período subsequente à implementação
do CCTV, destacando-se especialmente os crimes contra as pessoas e contra a
propriedade. Estes resultados sugerem que o efeito dissuasor esperado não se confirmou
neste contexto específico, podendo indicar, entre outras hipóteses, uma cobertura de
câmaras e capacidade de resposta operacional limitadas, bem como a criação de um falso
sentimento de segurança do sistema entre os cidadãos, gerando novas oportunidades para
o crime. Deste modo, o estudo proporciona um contributo empírico relevante sobre as
limitações e potencialidades reais da videovigilância, abrindo espaço para futuras
investigações que aprofundem os fatores específicos subjacentes aos resultados
observados, contribuindo assim para decisões mais fundamentadas em segurança pública.
In an era marked by growing investment in urban security technologies, video surveillance systems (CCTV) have emerged as important tools in crime prevention. Despite the global dissemination of these systems, doubts persist as to their real effectiveness, considering that the existing studies present contradictory results. Given the growing social concern about urban crime in Cape Verde, coupled with the population’s feeling of insecurity, the government has implemented the CCTV system on several islands, including São Vicente. The aim of this study is to specifically evaluate the impact of urban video surveillance on crime prevention on this island. To this end, a quantitative methodology was adopted, using descriptive and inferential statistical techniques in the analysis of crime data reported to the National Police, covering the period between 2017 and 2024. Contrary to what was initially predicted, the results indicate a statistically significant increase in crime in the period following the implementation of CCTV, with crimes against people and property standing out in particular. These results suggest that the expected deterrent effect was not confirmed in this specific context, and may indicate, among other hypotheses, limited camera coverage and operational response capacity, as well as the creation of a false sense of security of the system among citizens, generating new opportunites for crime. In this way, the study provides a relevant empirical contribution on the real limitations and potencial of video surveillance, opening up space for future research that delves deeper into the specific factors underlying the results observed, thus contributing to more informed decisions on public safety.
