Brazil. Facial recognition strengthens the security of the city of Praia Grande, on the coast of São Paulo, Brazil, and helps reduce crime in the monitored areas by 80%.
Public safety remains a sensitive issue in our society. Many governments have been looking for alternatives to help fight crime and the use of technology is gaining more space in this sector. Faced with so many possibilities, the city of Praia Grande, a city on the coast of São Paulo in Brazil, decided to increase surveillance at strategic points to more easily identify criminals and those wanted by the police. The project was the result of a partnership between the City Council, Digifort (surveillance system) and SAFR®, from RealNetworks, a high-performance facial recognition and computer vision software.
As in all tourist cities, Praia Grande also suffers from the invasion of wanted criminals by the police and, despite having a database of these individuals, monitoring them manually is an arduous and ineffective task. To automate the process of identifying wanted persons by the court before they had a chance to cause harm to the population, the city chose SAFR® as it is a faster and more accurate solution compared to manual monitoring.
RealNetworks facial recognition software has a recognition accuracy rate of 98.87% for real-world faces and 98.85% for masked faces.
SAFR® added increased situational awareness, easily detecting thousands of faces in the crowd and comparing them to a list of criminals registered in the official police database. The monitoring performed by the software does not collect or store any personally identifiable information (PII).
Along the perimeter of the city of Praia Grande, more than 2,500 security cameras are maintained for monitored surveillance, and among these, 180 are integrated with SAFR®. Since the implementation of monitoring and alarm technology in the city, the crime rate has been reduced by more than 80% in the monitored areas and intrusions into public buildings have almost been eliminated. According to the professionals involved in the project, SAFR® facial recognition software was crucial to obtaining these benefits.
"At the end of the day, when the result of our technical efforts results in reducing crime rates, improving the safety of local citizens and businesses, the contribution of video analytics to society as a whole is very clear. This is the main objective of everything we do," says Marcelo Victorino, Director of Sales and Business Development, for LATAM at RealNetworks.
