A camera or a number of cameras are installed in the baby s room and live video feed are transmitted to a TV or LCD receiver. These video devices can either be wired or wireless devices.

At daytime, a baby monitor also provides you with an enormous freedom to do other things during your baby's naptime. As a rule, you need to place the radio transmitter within 10 feet of the crib so that it can pick up even the slightest sounds made by your baby such as breathing and movement.
