We tested each product we purchased in key metrics that allow them to function as expected, or provides an additional feature or benefit. Monitors act as something of a lifeline for parents, so it is important that they work well, have adequate range, provide useful images, and are easy to use. If a product doesn't work well enough to instill confidence, then it will fail to offer parents the one thing they really want, more sleep.
If you aren't interested in having a video baby monitor, the VTech DM221 is the very best audio-only monitor you can buy. You can listen in on your baby or get vibration and light-based alerts when the monitor is in silent mode. The five LED lights indicate the level of sound so you can tell whether your baby is cooing quietly or shrieking for mom and dad.
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.
Unfortunately, The DECT SCD570/10 is one of the most expensive sound devices we tested with a price that rivals some of the video options. This higher price means that parents looking in this price range may want to consider a video product instead to get more bang for their buck. Alternatively, if you want a sound option with full-bodied sound and fancy features for baby, and you aren't interested in watching your little one, then the SCD570 could be the one for you.
Another Summer Infant baby monitor option, not quite as great as most others on this list, but definitely a trusted and reliable model and one of the best baby monitors available on the market this year. In our testing, one of the first things we noticed about this baby monitor was the sleek mobile-phone-size touch-screen reminiscent of the older iPhones. What's nice about this form factor is that it slips easily into your pocket like a mobile phone. Many of the others need to be clipped to your belt or waist, as they are quite a bit too thick or large for the pocket. The actual video display is modestly sized, coming in at 3.5" diagonal viewing area. This is the same size as the Infant Optics model. And it has some great features. It has remote pan (side-to-side adjust), tilt (up/down adjust), and zooming capability. Two-way audio communication so you can hear baby, and talk back to baby (maybe sing a lullaby, or whisper something to help soothe your baby). The system is also expandable to up to 4 cameras. Each additional camera is about $99, and you can place them in various locations around the home and toggle between them with the video unit. In our tests, the battery lasted about 4-5 hours when off the charger (and being used), and charged back to full capacity in only a couple hours. We didn't think the picture quality was as good as most other options on this list, nor was the sound. We also hooked it up to multiple cameras and used the "scan" feature which rotated through the various cameras once every 8 seconds. In our opinion, it took a bit too long to switch to a particular camera. It was also pretty loud when we remotely adjusted the pan/tilt of the camera. Also, it's worth noting that the pan feature doesn't seem to work when it's zoomed in. So overall, you're getting a good form factor, a reliable camera, but not the best image quality. For about $150, we think you could do better with one of our higher-rated options!
The most reliable type of movement sensing product is the mattress pad option. This product is placed under the mattress, usually on a hard board and will only work with some types of mattresses. This unit relays messages to a nursery device that alerts parents on a parent device or with an alarm in the nursery (model dependent). The BabySense 7 is a good example of a sensor pad that works under your baby's mattress.
The Motorola MBP33S is a digital video monitor with a multi-view feature that lets you incorporate additional cameras, so you can keep an eye on your baby in up to four rooms. Its large wireless range stays connected for nearly 600 feet, and the two-way communication helps you soothe your little one from the next room. Plus, the monitor displays temperature, so you can make sure your baby is never too cold or too hot.
Sound activation is a feature we think parents should consider. This feature creates a quiet monitor unless the baby is actively making noise and translates to parents potentially getting more sleep because they aren't kept awake by ambient noises. Having sound activation means you only hear what you want to. This feature can be found in dedicated and Wi-Fi monitors.
Motion and audio sensors: In the old days, parents were forced to endure a consistent ambient hiss from their audio monitors while they listened for their child’s stirrings or cries. Mercifully, many modern baby monitors will stay in “quiet mode” until they detect motion and/or sound, which will trigger an alert, such as activating the handheld video display or pushing a notification to your smartphone.
It’s hard not to like the crystal-clear picture you get on this monitor’s 7-inch screen (the biggest screen on this list!). Its standalone camera can be moved from room to room and will remotely pan, tilt and zoom. Given the cost, this monitor is best if you want full control of the nursery environment. It syncs with the Smart Nursery humidifier and the Dream Machine sound and light machine. Once connected, you can turn on lullabies, project lights onto the ceiling and increase the room’s humidity all from your monitor.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
