Long Range: Monitors that don’t connect to WiFi have a limited range, usually around 600 to 1,000 feet. While this is large enough for all but the biggest houses, we asked our testers to find out how far they could wander away — and how many walls they could put between them and the baby unit — before they went out of range, as well as to report back on what happened when they did. Sometimes there was an alarm or a notification, but other times the screen simply froze.
In addition to the standard parent and baby unit, these monitors include a device that tracks your baby’s movements, breathing, or heart rate, and offer time-sensitive alarms that alert you if your baby hasn’t moved in the last 20–30 seconds. While they aren’t proven to reduce SIDS, many new parents told us these monitors gave them added peace of mind.
Environmental sensors: Many monitors include the ability to set thresholds and upper limits for room temperature and/or humidity, and they'll alert you when these ranges are exceeded. While they can't control the temperature or the amount of moisture in the room's air, this feature can help you improve your child’s comfort, which will help them get more restful sleep.
"Quick and easy set-up is Nest Cam's secret sauce -- they promise a 60 second set-up and that's pretty much what we found in our testing," Baby Bargains says. Still, "Nest Cam isn't a perfect solution as a baby monitor." In addition to the signal dropouts, Nest Cam's audio cuts out anytime your phone's screen goes to sleep. It also drains the battery, Baby Bargains says, so you'll have to leave your device plugged in all night. The camera is fixed – it won't swivel – and the audio can lag behind by 3 to 5 seconds, depending on your router's speed.
If you sleep in the same room as your baby or live in a small enough space that you can always hear or see what your baby is up to, you probably don’t need a monitor. Otherwise, most parents enjoy the convenience a baby monitor provides—instead of needing to stay close to the nursery or constantly checking on your child, you’re free to rest, catch up on Netflix or get things done around the house during naptime. Monitors can also double as a nanny cam to keep an eye on your child and their caretaker.
