A scanner is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases.
The terms radio scanner or police scanner generally refer to a communications receiver that is primarily intended for monitoring VHF and UHFlandmobile radio systems, as opposed to, say, a receiver used to monitor international shortwave transmissions.
