The Peoria Police Department is implementing a new emergency communications system today. Peoria Police started using the new digital radio interface with sign-on this morning. The Peoria County Sheriff's Office has been using the system since earlier this year. The Peoria Fire Department is set to transition June 23. The the digital system upgrade replaces the decades-old analog infrastructure. The new technology adds capability for first responders to have direct interagency communication. That means Peoria County emergency responders using the new system will be able to make direct radio contact with Illinois State Police.
