More police precincts across the city are encrypting their radio communications.

The move took effect Monday at a number of precincts in the northern Bronx.

This means members of the public, including journalists, will no longer be able to listen in on officers’ communications in the area.

The NYPD has already encrypted its radios in all of Brooklyn and Staten Island and said its all part of an upgrade of its technological infrastructure.

The department plans to encrypt all precincts by the end of the year.

NY1 asked Mayor Eric Adams about the move at his weekly press briefing Tuesday amid concerns that encryption leads to a lack of transparencies.

“I think we really underestimate how much time criminals spend in outsmarting police, so we don’t want to give them our tools,” Adams said. “They are slick, they are determined to hurt innocent New Yorkers, and I’m determined to push back.”

Adam Wandt, associate professor and the deputy chair for technology at John Jay College of Criminal Justice, joined NY1 political anchor Errol Louis on “Inside City Hall” Tuesday to discuss this.
