Researchers have developed a prototype device that can disable digital cameras. In the future, this device could prevent covert photography from a distance and even stop secret video recording.

This technology could also stop espionage within a building or prevent the illegal recording of films in theaters.
The device uses sensors, projectors, and a computer to scan for and disable cameras. It looks for the reflective properties and shapes of imaging sensors embedded in these digital cameras. Future prototypes may even operate in the infrared wavelength, which is invisible to the naked eye, thus keeping the device concealed.
“Right now, we have developed a prototype that could lead to market-ready products capable of narrow protection,” said project leader Gregory Abowd from the Georgia Institute of Technology.
Digital cameras typically use a CCD (Charge-Coupled Device) that reflects light back to the source rather than scattering it. This characteristic makes them easy to detect. Once the CCD is located, the disabling device will project a thin beam of white light at the camera, rendering it unable to record.
Currently, the technology for stealing films in theaters is causing billions of dollars in losses annually for the film industry. “The biggest challenge is ensuring that the device does not confuse a digital camera with a large, shiny earring,” said research team member Jay Summet.
