baby monitor
A baby monitor, also known as a baby alarm, is a radio system used to remotely listen to sounds made by an infant. The transmitter, equipped with a microphone, is placed near to the child and the receiver equipped with a speaker, is carried by, or near to, the person caring for the infant. Some baby monitors are bi-directional, using transceivers that allow the caregiver to speak back to the baby (parent talk-back). Some allow music to be played to the child.
Baby Monitors are used by millions of families every year to help watch over their newborns and older babies. As technology has come into the field the baby monitors have gotten a bit fancier and actually do more - from sensing movement, sound and even with visual monitors for watching over your newborn baby. Some of the monitors that I find to be very useful,for example, the Graco Ultra Clear Monitor,Crisp and Clear Monitor,Graco Family Listen N Talk Monitor and Angelcare Baby Monitor.
