A police scanner is the name given to a radio scanner. A radio scanner is a special receiver that is capable of receiving wireless radio signal transmissions. These wireless signals include two-way radio transmissions used everyday in public safety and business operations.
A scanner picks up these radio signals, similar to an AM/FM radio. While an AM/FM radio is programmed to pick up only AM/FM band radio signals, a scanner can pick-up multiple radio signals and multiple radio bands simultaneously making it possible to easily keep track of many channels at once. The term police scanner comes from the fact that the majority of scanner users enjoy listening to police radio broadcast.
Radio scanning is the process of effectively tuning into and monitoring any wireless radio communication that interest you, provided that your scanner is capable of picking up those radio signals for your particular interest.
