Invisible to the naked eye, infrared light illuminates the unique contours of faces, bodies and license plates—powering many of today's facial-recognition systems and nighttime camera readers. In this photo essay, Associated Press photographers used modified cameras and a red infrared filter to make those beams visible, documenting how infrared is applied in public and private surveillance around the world.
Widespread Use and Everyday Encounters
Over the past decade, facial recognition moved from science fiction to everyday reality. China, now home to more security cameras than the rest of the world combined, deploys these systems at airports, train stations, busy streets and transport hubs. Chinese law requires people registering new SIM cards to appear before face-scanning cameras, and until recently many hotel guests were routinely asked to scan their faces at check-in.
Convenience, Safety—and Control
For many, these technologies bring convenience and a sense of safety. For others they are an intrusive tool of surveillance. Associated Press reporting found that much of the hardware and software powering China's networks was designed and supplied to a significant degree by U.S. companies—technology that, according to AP reporting, has at times helped enable human rights abuses and strengthened the capacity of the Chinese Communist Party to monitor dissent, ethnic minorities and even government officials.
Surveillance Beyond China
Similar systems have proliferated in the United States in recent years. AP reporting found that U.S. Border Patrol expanded a largely secretive program that used license-plate readers and other monitoring tools to track millions of drivers nationwide. Under the previous administration, billions of dollars were directed toward a broad range of surveillance systems, including networks of license-plate readers that have ensnared drivers simply for traveling near border areas.
How the Photos Were Made
AP photographers converted cameras to capture ultraviolet, visible and infrared light and fitted them with a red-tinted infrared filter that blocks certain visible wavelengths to better reveal infrared beams. Photographers on three continents captured images that show how invisible rays are used to follow people and vehicles, facilitate face recognition and extend digital control into everyday life.
Dozens of people who spoke with AP—from Tibetan activists and farmers to a former vice mayor—described being tracked by sprawling camera networks that restricted movement and triggered police attention.
