Following the September 11 attacks, the NYPD developed a large and sophisticated array of surveillance technologies, generating large collections of data including billions of license plate readings and weeks of security footage from thousands of cameras. This data is now used in the department's day-to-day operations, from counter-terrorism investigations to resolving domestic violence complaints. The system consists of an interconnected web of CCTV cameras, license plate readers, physical sensors, machine learning software, data analytics dashboards, and mobile apps.[1]
Now centered around the Microsoft-built Domain Awareness System, the NYPD surveillance infrastructure has cost hundreds of millions of US dollars to produce and maintain. Many of its core components are being sold to or emulated by policing departments across the world.[1]
The NYPD has credited surveillance systems as preventing numerous terrorist attacks on the city[3] and helping to provide evidence for hundreds of criminal cases.[16]
Unlike intelligence agencies such as the CIA, the NYPD does not disclose the budget or funding sources for its surveillance system.[17] However, this may change in December 2020 when the POST Act goes into effect.[17]
