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 don’t think most people would be happiest with a Wi-Fi–enabled baby monitor. The benefits—primarily, being able to view the camera footage remotely, on multiple phones, without keeping track of a separate monitor—do not make up for the disadvantages Wi-Fi monitors have as a category. Security is probably the first thing on most people’s minds. The likelihood of someone hacking into your baby monitor is remote, but it’s possible, said Mark Stanislav, director of application security at Duo Security, in an interview with The Wirecutter. You’re relying on the security of your own home network and also the ability of the manufacturer to secure all its devices. “Once you get into an Internet-connected device, and it really depends on what kind of device it is, but these devices very often bypass your home’s router and firewall. Basically, once you’re connected to this device, you are inside the home’s network. So, it’s possible to use these devices to access other devices in a home,” Stanislav said. (Stanislav was also involved in Rapid7’s research into the vulnerabilities of Wi-Fi–enabled monitors.)
Another prominent Wi-Fi–enabled monitor is the Withings Home video monitor, which we dismissed without testing. This is The Nightlight’s pick for the best video monitor. The most notable drawback to the Withings is that currently more than a third of Amazon reviewers give it two or fewer stars (out of five), citing problems similar to what you see on most other Wi-Fi video monitors: bad connectivity, a bad picture, unreliable air-quality sensors, and issues with overall quality and durability. In reply to some of the negative reviews, Nokia stated that it was looking into making improvements to this model. The rebranded version, the Nokia Home Video & Air Quality Monitor, was recently released and has not yet received many reviews (the app has mixed reviews).
We tested a Nest Camera for the sake of comparison, to see the advantages and disadvantages of a popular security camera versus baby monitors designed expressly for watching babies at home. We have also considered the Arlo Baby monitor, which we’ve seen in demos but not tested firsthand for this guide. Our findings are in Why not just use a security camera? For far more information on all the other similar options—including a detailed look at other Arlo indoor security options, like the Arlo Q—see our guide to the best wireless indoor home security camera.
But, for many parents, a baby monitor is a part of daily life. If you need to visually confirm that your baby is safely asleep for the night in order to leave the room and relax, it can feel like a necessity. 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. Monitors are most commonly used for new babies, but even once your household is past the infant stage you may appreciate an easy way to check to make sure your kid is still asleep, still breathing, or still in the room at all. It’s nice to see your children in bed, dreaming happily, sleeping in adorable new positions, cuddling with animals, and generally doing okay. A baby monitor can make that happen.
Poor quality and durability plague many baby monitors. Scores of reviewers on Amazon and other sites report that the Hello Baby HB32; Motorola MPB854Connect, MBP36XL, MBP33XL, MBP41, and MBP43; Infant Optics DXR-5; Summer Infant Dual View and Sure Sight 2.0; Levana Jena, Keera, Ayden, Astra, and Lila; Angelcare AC420; Philips Avent SCD570 and SCD630/SCD637; and VTech VM342-2 and VM343 don’t deliver on promised functionality and start to fail in some critical capacity within a year—often in much less time.
Baby monitors shouldn't be used as a substitute for adult supervision. They should be considered as an extra set of ears—and, in some cases, eyes—that help parents and caregivers keep tabs on sleeping babies. Using one can alert you to a situation before it becomes serious, for example, if your baby is coughing, crying, or making some other sign of distress. Experts warn that you can't rely on a monitor to prevent Sudden Infant Death Syndrome (SIDS).
We began by shopping for baby monitors like anyone else would if they had dozens of hours to do it. The process started with a long list of best sellers at Amazon, Walmart, Target, BuyBuy Baby, Babies“R”Us, and Costco. We found monitors recommended in editorial reviews, such as PCMag, Reviewed.com, and Tom’s Guide. We also read a ton of discussion among parents in the Amazon reviews—what features they found especially useful, and what problems tend to occur. Thinking of all this, and comparing those concerns against the things we’ve appreciated and despised in our own years of monitor use, we developed the following selection criteria:
So, we split our remaining finalists into three groups: WiFi Monitors for those who want to have an unlimited range or the ability to check in on their baby from anywhere, Movement Monitors for those who are comforted by hearing their baby’s vital signs, and a “standard” category for parents who want a quality monitor, but aren’t looking for that extra level of support.
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.
Many audio/video monitors feature infrared light or "night vision" so you can see your baby on the monitor even when she's sleeping in a dark room. And some audio models feature a night light on the nursery unit that you can activate from the receiver. Other features may include adjustable brightness, and the ability to let you activate music or nature sounds to soothe your little sleeper by remote.
From each category, we hand-selected our finalists: the monitors with the most positive reviews on Amazon and parenting blogs, plus any that had all four of our parent-favorite features. Then we sent several monitors home with three different testers, to see which ones actually made parents’ lives easier, and which ones were more trouble than they’re worth.
The LeFun camera connects to your WiFi, and you use the associated app to watch real-time footage in 750-pixel high definition. Because the product uses WiFi to transmit video, you don’t need to worry about walls obstructing the signal. The camera can pan an impressive 350 degrees and tilt 100 degrees, and it also has night vision that many reviewers say works well.
Though it’s not a video monitor, the Owlet does track your baby’s heart rate and oxygen while they sleep, and notifies you if something appears to be wrong. Just slip a comfortable wrap with a sensor over your wee one’s foot (it works with babies 0–18 months) and download the app to your phone. You’ll receive alerts in real-time should your child’s vital signs change. It also comes with a base station that changes color when something is up.
