How does a baby monitor work?
Baby monitors include a transmitter and a portable receiver. The transmitter remains in the room with your baby and transmits information to the portable receiver (also known as a 'parent unit'). For optimal functioning, place the transmitter within one or two metres of your baby’s crib. The receiver can be carried around the house or left in your bedroom plugged in. Motion sensors can be placed under the mattress to detect your baby’s breathing pattern.
An increasing number of baby monitors can also be connected to your smartphone, tablet, or desktop computer, helping you to keep a close eye on your infant, toddler or child from even further away.
