You can control the Arlo via multiple platforms, including Alexa, HomeKit, Google Assistant, and IFTTT. The camera itself can work wirelessly off a rechargeable battery for several hours (which no other monitor we’ve tested can do), and it can track and chart several days’ worth of temperature or humidity in a child’s room. You can set it to notify you if it detects unusual temperatures, humidity levels, or “air quality,” a VOC measure the Arlo Baby manual (PDF) suggests you alleviate by either opening a window or removing the source of the VOCs. (Our also-great pick for the best air purifier is one of the few that actually does genuinely eliminate VOCs, but it ain’t cheap.) If you find that the notifications are too frequent, you can adjust what’s triggering the alerts (by raising the threshold up to 80 ºF, for example, if you don’t want a notification telling you it’s too hot at 76 ºF). You can store video from the camera online, but in six years of parenthood we’ve never once wanted to review baby monitor footage.
Most dual monitors come with split- or even quad-screen viewing, and the DBPower Digital Sound Activated baby monitor does just that. This model supports up to four cameras, allowing you to monitor four rooms at once. With features like remote pan/tilt/zoom, room temperature monitoring and alert, two-way communication and manual or automatic video recording, we found the DBPower to be the best dual baby monitor.
A big screen, a camera that zooms and a built-in nightlight make the In View monitor a great pick when you’re on a budget. The monitor also offers all the standard features: low-battery and out-of-range indicators, sound-activated lights and rechargeable batteries for the handheld monitor. Use the camera as a tabletop or mounted on the wall. And if you plan on having a big family, the monitor works with up to four cameras.
Another prominent Wi-Fi–enabled monitor is the Withings Home video monitor, which we dismissed without testing. 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, shows a similar negative pattern in its reviews (the app also has poor reviews).
You can get the same system, with a traditional monitor screen that’s slightly smaller at 4.3 inches, for cheaper. If you’re interested in having two zoom cameras or an app that lets you see your baby while away, Project Nursery offers those configurations as well. You can also record video and take photos with it as well (requires an SD card sold separately).
We tested more than a dozen cameras over the course of 40 hours of research and testing. The Withings Home delivers top-notch picture quality, has the widest angle lens, includes many bonus features like lullabies, background audio smartphone support, privacy mode, a soothing nightlight and Apple Watch support. There’s even support for streaming to the latest Apple TV. Its cloud-connected features alert you to noises and movements consistently, and because the signal beams to your iOS device (or Android, if that’s how you roll) rather than a short-throw standalone video monitor, you’re never out of range.
The features we focused on were those we thought either increased the performance of the monitor or made it more user-friendly for parents and increased the odds of getting good quality sleep. We looked for monitors that have sound activation that keeps the parent unit quiet when the baby isn't crying, so parents can potentially fall asleep faster because they don't have to listen to white noise. Some of the monitors were so loud, even at low volumes, that the white noise might keep light sleeping parents awake; this defeats the purpose of having a video product to begin with. We also liked the models with screens that automatically "wake" and/or go to sleep.
