In an upcoming paper we take a look at the impact of a massive intro of police-monitored camera in Montevideo (the resources city of Uruguay, with 1.5 million locals). In 2013 the Ministry of the Inside of Uruguay began to set up surveillance cameras in some locations of the city. These video cameras are constantly delighted in by police officer situated in a surveillance centre that incorporates video protection technology with the activity of polices patrol response.

Figures 1 as well as 2 summarise the geographical circulation of the areas monitored by security webcams, the irregularity in the setup days throughout various road sections, in addition to criminal offense incidence in Montevideo in October 2012 (prior to the start of the program). Customarily, criminal offense is gathered in small locations that include not just the street sections covered by police-monitored cams, yet similarly other areas throughout the city.
