The Infant Optics’s range within our test houses was never an issue, and, as with other monitors we tested, we had to walk outside and down the street before losing the signal. The image quality was good enough to make out facial details 6 feet away in a completely dark room (as it was on others we tested). You can easily add more cameras to the set—you can use up to four Infant Optics add-on cameras, which are separate purchases, usually for about $100. You can mount the camera on a wall easily; pan and tilt 270 and 120 degrees, respectively; and set the parent unit to scan between multiple cameras to keep an eye or ear on everybody at once—another nice feature that’s not unique to this model.
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.
But, for many parents, a baby monitor is a part of daily life. A baby monitor gives you a camera and/or microphone near the crib, and a separate rechargeable parent unit (aka, a monitor) that connects wirelessly and can travel with you throughout the house, either working while plugged in or running off its battery. It's nice to see your children in bed, dreaming happily, sleeping in adorable new positions, cuddling with animals, and generally doing okay.

For the parent devices of dedicated monitors, the battery life ranged anywhere between 6.75 and 12.75 hours. The Wi-Fi options are harder to gauge given that the battery life depends on the kind of device used, whether or not it is being used for other applications simultaneously, and how old the battery is in the device. In general, however, we feel it is relatively safe to say that most will work longer than the best dedicated monitor battery if the device is dedicated for use with the monitor only and is not running other applications simultaneously.
Sound devices relay what is happening in baby's room via sound only. A great sound option is quiet unless the baby is making noise so that you won't be disturbed by white noise or constant static. This basic monitoring type can be all you need if your goal is being alerted when your baby is crying and needs your assistance. This style can be elementary with sound only like the V-Tech DM111 or it can have bells and whistles like a nightlight, 2-way talk, lullabies, and mic sensitivity adjustment features like the Philips Avent DECT SCD570/10. Most parents can get by with a sound only device as it provides the information you need to determine if your baby needs you or not.
While we chose the Withings Home as our top pick, we know that not everyone wants a camera that connects to their phone. One expensive alternative that we grew to love was the Motorola MBP36 ($230). Its video sharpness doesn’t compete with the Withings Home, nor can it see nearly as wide, but the 3.5-inch screen still captured subtle movements, and you can change the camera angle remotely. Oddly enough, though, our absolute favorite feature was the design of its LED audio monitor. Both clear and soothing (the LEDs aren’t blinding, they’re just gentle, subtle lights), we kept it running long after formal testing was complete. We also found its range to be above average, as we were able to sneak down two flights of stairs in an old brick building and maintain signal. Three flights down, outside our building, we found the connection to mostly freeze, but the monitor never gives up—it keeps scanning for hints of frequency to give you audio and video updates. As a company, Motorola is a long-time pro at juggling radio frequencies across their products. Here, it shows.
In addition to being untested for efficacy, physiologic monitors can increase both your stress and your baby’s stress with false alarms and unnecessary trips to the hospital. Dr. Christopher Bonafide, of the Children’s Hospital of Philadelphia wrote that parents are increasingly bringing healthy babies to the hospital over a false alarm, noting that changes that often set off a monitor are “just normal fluctuations.”
The patterns you see in most owner reviews support our findings, with various folks noting the excellent video quality, and, often, ultimately rating the product poorly because of its inability to consistently maintain a connection, problems with the app, issues with the app’s updates not working with their particular phone, or other basic connection problems.
Testing battery life for all the monitors was for the parent device only. While some of the dedicated options have a battery in the camera in the event of a power outage, most do not, and they are not intended for use as an all-night option. So while we would support a cordless camera for monitoring baby, due to safety concerns with babies and strangulation hazards, none of the products in our review offer this.
To test each camera’s night vision, we used the monitors in darkened bedrooms with blackout curtains, with and without night-lights. For a more extreme test, we set the cameras up in a windowless room in a basement with a towel blocking light from the door. We aimed all of the cameras at a doll’s face approximately 6 feet across the room, looked at the monitors, and tried not to creep ourselves out.
Most people want to use a monitor at home, overnight, with audio on in the background, checking in on the video signal only occasionally. Our pick makes that task simpler and more reliable than an Internet-connected monitor. But if you regularly want to access the monitor while away from home, the Arlo Baby is the best Wi-Fi–equipped option. Whether you’re at home or away, the Arlo streams exceptionally sharp video to your smartphone’s Arlo app, and can save clips too. Unlike other Wi-Fi–enabled monitors, the Arlo also has the advantage of a longer track record, larger owner base, consistent app support, and strong reviews, as well as the rare ability to stream audio in the background with the phone screen off. But Arlo’s reliance on your phone and an Internet connection creates its own annoyances. It has routine issues with maintaining a connection and staying logged in. Additionally, glancing at your phone to check on the baby often comes with a side of unrelated and unwelcome push notifications.
The Infant Optics DXR-8 has a superior battery life to any of the other video monitors we tested, as well as a simpler monitor interface that's more intuitive and easier to navigate than those found on competitors. The range, image quality, price, and many other features are comparable with those of the best competitors. Other good qualities include a basic but secure RF connection, an ability to pair multiple cameras, and simple tactile buttons.
Using the speaker, you can tell the Project Nursery camera to pan and tilt, play a lullaby, check the temperature in the nursery and more. You can do all this from any room that has an Alexa-powered speaker, so that you don't need to enter the nursery and risk waking up your sleeping baby. If you already own an Echo speaker, Project Nursery sells the Alexa-enabled camera on its own.
The Vtech DM221 offers the features you need, coupled with the best sound clarity in our review of sound products. The DM221 comes with easy to set sound activation and adjustable mic sensitivity to help create a peaceful environment for a quality night's sleep with a parent device that only makes a peep when your little one does. The DM221's parent unit talk to baby feature sounds natural on the baby's side so your infant won't be alarmed by a robotic or static sound found in some of the competition. This unit is a budget-friendly choice that will work for almost any family.
If that's all this multi-function device did, then it would still be worth its price tag. But REMI does more yet. As your child gets older and can begin to manage his or her own sleep schedule, REMI helps the kid out by serving as a sleep trainer. You can program the time that your child is allowed to wake by having REMI wake up at the appointed hour. And to calm and soothe a child, you can use this Bluetooth enabled device as a speaker, playing music or talking to your child via REMI app connection.
To use it, just place the sock on your baby’s foot to keep track of your little one’s heart rate and oxygen levels. All night long, the sock will send that health data to an app on your phone, which means you can check on your baby without ever getting out of bed. Moms love the easy-to-use app and rave about finally being able to get a peaceful night’s sleep. If, for some reason, the sock comes undone or your baby’s heart rate and oxygen levels go outside the normal range, you’ll get an alert. You can stay asleep until you absolutely need to be awake—and those valuable minutes count!
Like many monitors in this price range, the SafeVIEW provides a lot of bells and whistles: remote zoom, tilt and pan of the camera, two-way communication and a range of 900 feet so you don’t have to stress about chatting with your neighbor outside during naptime. The SafeVIEW also has a built-in nightlight that you can turn on and off using the monitor. And, if the monitor is going nuts every time a big truck drives by or during a thunderstorm, you can decrease its sound sensitivity to not pick up the background noise.
The price of the Infant Optics, about $150 at the time of writing, is on the higher end for baby monitors. As much as we wanted to recommend a more affordable video monitor, we found their shortcomings to be major enough—terrible video quality and poor connections were common—that we couldn’t recommend one. The Infant Optics offers a better value even though it’s among the more expensive options available. Many people use these daily for years, which helps justify the investment, and the reports of reliable customer service from other owners are reassuring. If you have to spend less, go audio-only.
A baby monitor, also known as a baby alarm, is a radio system used to remotely listen to sounds made by an infant. An audio monitor consists of a transmitter unit, equipped with a microphone, placed near to the child. It transmits the sounds by radio waves to a receiver unit with a speaker carried by, or near to, the person caring for the infant. Some baby monitors provide two-way communication which allows the parent to speak back to the baby (parent talk-back). Some allow music to be played to the child. A monitor with a video camera and receiver is often called a baby cam.
We tested monitors daily over a period of several months, in three houses: one nearly 100 years old with plaster walls, a newer home with standard drywall construction, and a two-level 1960s home with a driveway on another level from the kids’ rooms. We tried the Wi-Fi–enabled monitors with two routers, in separate test locations, to be sure that any connection issues were with the monitors themselves and not the Internet connection.
Many parents find that a basic sound product more than meets their needs. They plan to run to baby's aid each time they hear them cry, and they don't need to spy on their baby with video. Using a sound option is the cheapest way to go to get a quality product that works well. However, if you need or want to see your baby, then a video option is the only way to meet this need. Choosing a Wi-Fi option means no concerns about range, the ability to see your baby when you are away from home, and usually better image quality. Wi-Fi also means you'll be able to use it for longer as potential security or nanny cam; this adds value you may not be considering right now (but should). Movement monitoring options are a luxury that most parents can do without. If you're worried about your little one and SIDs, studies show that having a baby sleep in their own bed in your room (along with standard safe sleep practices) goes a long way in helping to prevent SIDs and could potentially be more effective than movement monitoring. Choosing a great beside bassinet may be a better solution than a movement product. However, if your heart wants a movement product, then be sure to consider a sound or video option to pair with it so you can be sure to hear the alarm from another room.
The best baby monitor apps allow you to monitor baby using only your existing devices, like phones, tablets or even computers. One device acts a transmitter in baby’s room, and you use another device to monitor baby. Some apps only have audio functionality, but others have both audio and video. As a plus, the best baby monitor apps often have cool features that traditional baby monitors don’t have, like remote capabilities. However, some users complain that they can be somewhat unreliable.
Unfortunately, picking up the Arlo for that super-brief check-in is rarely as simple as on a basic video monitor. The Arlo loses its connection routinely, for example. You sometimes have to log in to the app again. Or the app freezes, showing video from hours earlier, or crashes, at times because the app or your phone’s OS is due for an update. Or you pick up your phone to check on the kids and end up stressing out about some other notification you didn’t mean to see at 4 a.m.
