police scanner
Emergency frequency receiver
A police scanner is a radio receiver that monitors frequencies used by police, fire departments, and emergency services.
Hobbyists and journalists use them to follow local incidents in real time: He heard about the accident on his police scanner.
Many jurisdictions have moved to encrypted digital systems, limiting what civilian scanners can pick up.
