RALEIGH -- The Raleigh Police Department is about to get equipped with some new technology.

Raleigh City Council unanimously approved the department's body camera policy on Tuesday, clearing the way for 600 body cams to come to the police force.

The purchase includes 450 new dash cams and the infrastructure for all of the cameras' data and will cost $4.7 million over three years, according to Raleigh Police Chief Cassandra Deck-Brown.

"You'll see that device a mile away on that officer so you'll know that they'll have it," said Deck-Brown. "I just think this is where we are with 21st century policing."

The cameras will record events such as arrests, traffic stops and violent incidents. However, the American Civil Liberties Union remained concerned about the ability for police to watch their own footage before writing a report.

"Officers' reports shouldn't be supplemented by what is on the body camera recordings," said Susanna Birdsong of the ACLU. "Those recordings should be a neutral view."

RPD is also responsible for all of the data recorded by the body cameras.

Deck-Brown expects the first body cameras to deploy between March and May.
