Parents are spoiled for choice nowadays, thanks to the rise of the connected home and new technologies like live-streaming video and high-resolution cameras. No matter which type of baby monitor you buy — whether it be an old-school audio-only monitor or a fancy Wi-Fi video monitor — it will have two parts: a monitor in the baby's room and a receiver that you carry around with you to hear and/or view your baby.
Gone are the days of silently peeking into the nursery to check on your napping baby and then, whoops, accidentally waking them up (“No, no, please no!”). A baby monitor uses a camera to watch over the crib, while you carry a handheld device that lets you know what’s going on with your child at any given moment, no matter where you are in your home. There are also other monitors that track sleep or breathing either with a clip or sock.
