The range of a product can make or break whether or not you can use certain options in your home. Depending on the distance from your room to the baby's nursery and the construction of your home or interfering appliances, you could be limited in your options of what will work for you. If your house is large or has more than a handful of walls between the two room, you'll be stuck with a Wi-Fi option only (assuming you have Internet). If your home is smaller or has fewer walls, then you'll have more options. Many of the wearable movement choices work in the baby's room and are not dependant on communicating with a parent device. However, if your room is out of earshot, then you'll never hear the alarm go off making the unit virtually useless without a sound monitoring addition. Choose your product carefully if you think the range will be an issue and purchase from retailers like Amazon that have a generous return policy. Also, don't let it sit in the box, try it out right away and send it back immediately if it doesn't work in your space. Do not rely on the manufacturer's range claim, as we have found these claims to be wildly inaccurate for many brands during our testing.
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.
