US police agencies are raising security concerns that Meta smart glasses, including Ray-Ban Meta models, could be used for covert recording in police facilities, according to internal memos cited by multiple outlets. The documents describe the glasses as equipped with small cameras and microphones and warn they may enable people, including those in custody, to film without permission.

The reporting centers on a January memo from New York City’s Police Department counterterrorism unit. It advises officers to inspect eyewear permitted within inmate cells and flags the glasses as a potential “security and counterintelligence” threat. The memo points to examples of videos filmed with similar devices that have circulated on social media.

Other coverage characterizes the concern as involving broader coordination and notification beyond the NYPD, describing the glasses as a risk for covert filming inside jails and police facilities and noting that relevant communications also reach federal partners such as Homeland Security. Across outlets, the emphasis is on operational and investigative risk, rather than confirmed wrongdoing.
