What is a police scanner?

Police scanner is a device used to scan radio frequencies used by the right to enforce. The scanner is able to listen to more frequencies at the same time and play transmissions as they are accepted. Police scanners are also known as radio scanners, and most of them are able to listen to frequencies far beyond those that only use law enforcement. Specialized models are also able to decrypt coded signals, although the legality of such models can be questionable in some regions of the world. The ability to listen to several frequencies at the same time allows people to hear numerous communications at the same time, which can be very useful for people like dispatchers. Most police scanners have a Squelch function, so the speaker only activates when the device finds the sound to play. This ensures that people are not forced to listen to, while the scanner is looking for the frequencies they broadcast. The available features depend on the model.

Some functions may not be legal in all areas, and people should be careful when buying a scanner to confirm that the law does not break.
