Safe City or Safe City is a term that is gaining space in the world and in Brazil. It refers to an approach that seeks to integrate technology, urban planning, public policy and community engagement to address challenges related to urban security. In this concept, several resources can be implemented, such as the installation of equipment with advanced technology, intelligent sensors, real-time data analysis and surveillance systems, with prevention strategies.
In a country marked by socioeconomic challenges and a complex reality, the search for innovative solutions to promote safety and well-being in cities has become a priority. The ideal scenario is collaboration between the various sectors involved such as local governments, companies, civil society organizations and citizens for this type of approach to seek efficiency.
According to the last Safe Cities Index (SCI), published in 2021, Tokyo, Japan is the safest city in the world. The index takes into account issues involving various aspects such as digital and personal security, health, infrastructure and environment for living, working and leisure. Brazilian cities such as Rio de Janeiro and São Paulo also appear on the list, but in intermediate positions. Thus, to evolve in the context, it is interesting to know five strategies that can transform urban security in Brazil:
1 – Safe Cities in the Brazilian context
To achieve beneficial results in urban security in Brazil, it is necessary to understand the particularities of Brazilian cities. A concrete example that implemented strategies focused on reality itself is São José dos Campos, in São Paulo. The municipality in the interior of São Paulo adopted a wide monitoring system with smart cameras, combined with sensors integrated into the urban infrastructure, such as lighting and traffic lights. Theft rates dropped by 80%, demonstrating the effectiveness of smart cameras in deterring crimes and identifying suspects. Furthermore, vehicle theft has dropped of 66%, thanks to dynamic detection and response to suspicious situations captured by cameras with embedded intelligence.
2 – Invest in a monitoring system with smart cameras
One of the most significant innovations within the approach to Safe Cities is the use of cameras with embedded intelligence, which integrate the concepts of AIoT (Artificial Intelligence of Things) with edge processing. Smart cameras are capable of capturing, processing and analyzing data in real time, without the need to transfer their video stream to remote data centers for processing. Such edge handling enables instant event detection and analysis, reducing latency and increasing operational efficiency. These cameras use advanced computer vision and machine learning algorithms to identify and interpret objects, movements and behaviors in real time. Smart cameras can detect suspicious activity such as break-ins, vandalism, aggressive behavior and even facial recognition to identify people wanted by authorities. It is worth noting that the monitoring feature with smart cameras allows projects to come out more economically. As analytics processing takes place at the edge, embedded, processing in the data center does not increase exponentially as in the traditional model. If a city hall, for example, starts monitoring with 40 license plate reading cameras, it can scale the project to 200 new cameras without the need to change the processing infrastructure in the center, since the heavy part is shipped at the edge.
3 – Installation of Cameras with multiple lenses
In addition to camera technologies with embedded intelligence, other innovations have driven Safe City around the world, including the launch of multi-lens cameras. These cameras offer advanced features that save on data link, energy consumption and infrastructure, while increasing operational efficiency and the quality of captured information. One example is speed dome cameras with a fixed panoramic lens. They combine a panoramic lens that covers a wide area with a speed dome camera that provides controlled panning and zooming. In addition to the aforementioned model, there is another efficient option, but at a lower cost: the TandemVu line. Instead of having two cameras installed in one location, there is only one with two functions. This technology makes it possible to integrate the detections on the Bullet camera with the Speed Dome. Before this line, the integration of detections depended on a centralized software that coordinated the detections and tracking in the PTZ, which entailed software license costs for integration and non-operation when a connectivity problem occurred.
4 – Pay attention to new technologies
The technology of security systems, cameras and monitoring often changes quickly, so equipment tends to become obsolete in less time. It is ideal for authorities and those responsible for urban security to keep up to date on available innovations and seek to adapt to new technologies.
5 – Engagement between community and police
Even with the most advanced technology to monitor a city, it is interesting that the population and the police do not work together. Cities can invest in the creation of solidary neighborhood programs, in which residents of a neighborhood help monitor the streets and have a direct line with local authorities, to make complaints and reports of possible crimes such as house break-ins, depredation of public property and car theft. By promoting these initiatives, citizens tend to be more engaged with a smart security system.
