General Usability: This one is two-fold. First we wanted to make sure each monitor could perform under bright, dim, and no light; and pick up even the faintest sounds. Then we looked at how easy it was to use the monitor. Could we adjust the screen brightness, or were we going to be half-blinded when we picked it up at 1AM? Was the monitor voice-activated, or does it pick up white noise in the background? How sensitive were the alarms, and did they sound like a baby-waking screech or a soft ping?
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.
While buying an audio-only monitor in 2018 is slightly akin to buying a flip phone, the Philips Avent has pretty much all the same features as top-of-the-line camera baby monitors, sans camera. Even better, it uses DECT (Digital Enhanced Cordless Communications) technology to guarantee zero interference ⏤ so it won’t get crossed with other signals in your house and/or your neighbor’s cordless phone. The Philips has a range of more than 90-ft inside, a 10-hour battery life, and it uses a “cry mode” so you’re only alerted to real cries for attention rather than background noise. As for extra features, it includes a night light, in-room temperature monitor, and plays lullabies ⏤ if only you could just see the baby.
It may surprise you to hear that simply being able to last through the night, unplugged, with the display off, qualifies as exceptional battery life for a baby monitor. The Infant Optics was one of the only monitors in our testing that could easily do that, and then last a while longer the next day. That alone puts it head-and-shoulders above many other monitors we tested.
If you're looking for a smartphone-compatible baby monitor that's designed first and foremost to fill that role, Wirecutter calls the iBaby M6S (Est. $135) "the least bad Wi-Fi monitor (so far)," simply because it's "slightly easier to set up than its competitors." Once again, however, experts disagree: Baby Bargains says Nest Cam "runs circles around iBaby when it comes to set up and ease of use."
By default, Arlo Baby records in 720p resolution, though you can switch to 1080p if you prefer. You can also adjust the field of view and fine-tune notifications on what triggers an alert. You do have to position the camera manually, however, and the gap between getting a notification on our phone and actually being able to jump to live video was a little laggy for our tastes.
This monitor is known for its zoom lens, included in the box, that lets you see your baby up close even if you have to position it farther away from the crib. You can use the monitor to remotely adjust the camera, and you don’t have to worry about plugging the monitor in overnight—it can sit on your nightstand for up to 10 hours in the power-saving mode (similar to sleep mode on your computer, but it still provides sound monitoring while the display is off) and up to six hours with the display screen constantly on.
