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.
Range: Range is the main drawback of an RF model, as audio monitors can roam farther out, and a Wi-Fi connection can theoretically be checked anywhere. We wanted an adequate range in a typical home—to be able to maintain a signal up or down a flight of stairs, across the house, and out on a patio or driveway, but we didn’t expect much beyond that. We zeroed in on monitors rated to about 700 feet of range1 or greater.
With a dedicated baby monitor, push-to-talk capabilities will usually be integrated, as well as the ability to record and share still images and video clips (even if some monitors require a subscription to do so). Baby video monitors will also usually have built-in music files that you can play to soothe your child. Just the ability to pan and tilt the camera — the Nest has a fixed 130-degree wide-angle perspective — means you can follow your kids wherever they scamper.
Dropped connections are another problem. "We tested our Wi-Fi monitors on two separate routers and consistently had problems -- we'd often lose the connection some time in the night and not even realize that the monitor had disconnected until morning," Wirecutter says. "This happened with all three Wi-Fi models we tested. We never really felt confident relying on any of the connected monitors overnight, despite the fact that the modem and router were literally on the other side of a wall from the monitor."
Movement products are designed to sense the movement associated with a baby breathing. These products attempt to discern when your little one has not moved within a prescribed period that could indicate that they have potentially stopped breathing. While this may seem like a no-brainer option for parents worried about Sudden Infant Death Syndrome (SIDS), they are not foolproof, have not been approved by the FDA as a medical device, and are known to have false alarms where the baby is fine but then suddenly awakened by a loud alarm. While it is an interesting kind of product, we caution parents that this type of device is not a substitute for safe sleeping practices and doesn't prevent SIDS. However, if you are willing to accept false alarms, it can provide another layer of monitoring to help some parents sleep better at night. Movement sensing products are only useful until babies start to roll over, at which point they become unreliable.
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.”
If you’re absolutely sure you want a Wi-Fi–enabled baby monitor, we found the iBaby M6S to be the best option of the three we tested (the others were the Arlo Baby by Netgear and the Evoz Glow Baby Monitor). The iBaby offers the benefits common to most Wi-Fi monitors and is slightly easier to set up than its competitors. But like its competitors, it shares the significant drawbacks, noted above, that we believe make RF monitors a better choice overall.
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.
We wanted to recommend an inexpensive video monitor, but their flaws were so significant that we decided we’d rather spend less on a quality audio-only monitor like the VTech DM221. This is a well-reviewed best seller in the category, and it has crisp sound and better talk-back functionality than the best video monitors we found, as well as a longer range and better battery life than our video picks. It easily beats out its audio-only competitors for various basic reasons like being cordless, rechargeable, or less expensive.
This is a light or beeping sound that lets you know that you've reached the monitor's range limit. If you have a model without this feature, static might be the only indication that you're out of range. (A monitor's range can vary due to your home's size, its construction materials, and other factors.) The greater the range, the better--especially if you plan to take your monitor outside.
The Nest Cam isn’t a dedicated baby monitor, but an all-around home protection device. Besides aiming the camera at the crib, you can also use it to keep an eye on the nanny, the dog or your empty home while you’re away. The video camera can be set up anywhere, and you can watch the live streaming from your smartphone. It also has two-way communication so you can soothe your little one to sleep, even if you’re offsite. If the device senses motion or sound, it’ll send a phone alert or an email to you. Missed what happened? From the app, you can view photos of any activity that took place over the last three hours. (There are Nest Aware subscriptions available that provide access to 5, 10 or 30 days of recordings, for $5, $10 or $30 a month, respectively). The picture quality is super sharp, too.
