A typical baby monitor, also known as a baby alarm, is a simple transmitter and receiver system used to remotely listen for noises made by an infant.
The transmitter, equipped with a microphone, is placed near to the child and the receiver equipped with a speaker.
Some baby monitors are duplex ,using transceivers that allow the parent to talk back to the baby ,and some have a feature allowing music to be played to the baby.
One of the primary uses of baby monitors is when the baby is asleep, allowing parents to keep track of the baby.
