You might see monitors on the market with claims that they can track a baby's breathing or movements, but unless the unit is registered with the FDA, it's not a medical device. Consumer Reports hasn't tested this type of monitor. Talk with your pediatrician if you think your child has a condition that warrants medical monitoring. He or she can give you advice on the best devices.
The HelloBaby might be a standard monitor, but it excels at the basics. It scored better than some of the more expensive WiFi monitors in picture clarity, and was hands-down the easiest to use. Just open the box, plug in the two devices, and you’re ready to go. No difficult packaging to tear through, and no account setup or device pairing necessary. Our testers had it up in running in less than 3 minutes each time.
It uses 2.4GHz FHSS technology that offers a private connection between the monitor in your baby's room and the dedicated viewer in your hand. The FHSS connection should minimize interference, and most reviewers say the audio is clear. In BabyGearLab's testing, the reviewer found that the Phillips AVENT had the best audio signal of any of the monitors it tested.
The main reason you’re going to need a baby monitor is to answer a simple, but time-honored, question: Why the hell is my baby crying? It’s only been in the last 30 years or so that parents have relied on the remote surveillance of their sleeping children. For the eons before that, it was a combination of natural, ear-piercing cries, and sleeping in the same yurt.
The VTech DM221 audio monitor is the best choice in the category—it's consistently a best seller at multiple retailers, with thousands of positive customer reviews. Losing video is a major sacrifice, of course, but we could see this monitor being a good choice for parents of toddlers who are considering replacing a failing monitor, or people who want a monitor only so they can hear their kid crying out from a distant bedroom.
Baby's exposure could potentially be even lower if parents place the camera on a wall at least 15 feet from baby (a distance still good for night vision to work properly with most monitors). Given the sensitivity of baby's developing systems we recommend placing the monitor as far away from the baby as possible while still being able to utilize the night vision as intended and see baby's face to determine if they are awake or sleeping at a glance. For most of the products, this distance is between 10-15 feet from the baby.
The Nanit couldn’t be more perfect for analytical types. The camera—when placed just so—uses computer vision to watch your baby’s every move, and then tell you what it means. You get a notice on your phone, which acts like a handheld monitor, when your child is awake, acting fussy or has fallen asleep. The Nanit also assigns a sleep score to each night based on how many hours your child was actually crashed out. Other stats include how many times you went into your child’s room and how long it took for your little one to fall asleep. Because the Nanit streams live video and audio to your phone, you can also check in on your kiddo when you’re away from home. It also has a nightlight and temperature and humidity sensors.
One minor but potentially annoying flaw: The “on” lights on the parent unit are a touch bright, and you may be more sensitive to them since you’re likely to have the unit within view as you sleep. They appear as greenish yellow light from the face of the unit, and a charging light, which is blue when it’s fully charged. Depending on how sensitive you are to light, you may want to lay the display face down on a nightstand or cover the status lights with tape.
Still, the video delivered by the Arlo Baby was crystal clear, even at night. A whole host of sensors — temperature, humidity and air quality — can alert you to any change in your kid's room. The versatile app can send you notifications however you want, and we were particularly impressed by an Always Listening mode that streamed audio to our smartphone.
Project Nursery offers a variety of monitor options that include fantastic features like remote camera control, two-way communication, motion, sound and temperature alerts and the ability to play white noise or lullabies. But what we like best about this one is that it comes with a traditional 5-inch screen monitor and a 1.5-inch mini video monitor that you can wear like a bracelet. Both monitors have a long battery life, too.
