A word of caution about extremely cheap baby video monitors (we're talking devices that cost less than $50): they're not known for their security and can be hacked. Be sure to always change the default password of any connected device you purchase. You can also protect yourself by sticking to known vendors who post frequent firmware updates and have easy-to-reach customer support.
Sound devices relay what is happening in baby's room via sound only. A great sound option is quiet unless the baby is making noise so that you won't be disturbed by white noise or constant static. This basic monitoring type can be all you need if your goal is being alerted when your baby is crying and needs your assistance. This style can be elementary with sound only like the V-Tech DM111 or it can have bells and whistles like a nightlight, 2-way talk, lullabies, and mic sensitivity adjustment features like the Philips Avent DECT SCD570/10. Most parents can get by with a sound only device as it provides the information you need to determine if your baby needs you or not.
Netgear brought the best features of its Arlo line of home security cameras to its first baby monitor. That includes Full HD video, night vision, sound and motion detection, two-way audio, 24/7 recording, and free cloud storage. Netgear also used feedback from Arlo owners to add a nursery-centric spin to the Arlo Baby, with a multicolored LED nightlight, a built-in music player with nine lullabies, environmental sensors, and artificial intelligence that can recognize your child’s cries.
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.
The longest battery life for the dedicated products in our review is the Levana Lila, which ran for 12.75 hours in full use mode. The manufacturer claims this unit will work up to 72 hours in power saving mode, but we only tested the monitors in full use. The Infant Optics DXR-8 came in second place with a shorter run time of closer to 11.5 hours. The Motorola MBP36S earned the lowest score for battery life with a runtime just under 7 hours. While not necessarily a deal breaker, there are plenty of other reasons to dislike the Motorola MBP36S, and the battery life is just a small part of a disappointing overall picture (no pun intended).
It should come as no surprise that we selected Nanit as the best baby monitor overall—after all, it was the winner of The Bump Best of Baby Awards this year. Nanit gives you both a clear, unobstructed view of baby thanks to the over-the-crib mount as well as sleep insight reports and nightly sleep scores via an app. You not only see how baby sleeps, but learn how to help baby sleep better.
Some audio/video monitors filter out "normal" sounds and motions. The receiver is supposed to turn on only when your baby makes an unusual motion or sound, such as crying or rolling over when he's waking up from a nap. This feature is designed to extend battery life, although the receiver should be docked for overnight monitoring to keep the battery charged. We haven't tested any models with this feature, so we don't know how well it works.

If you want to know everything about your baby, down to the heartbeat — the Angelcare AC315 is our top motion-sensor monitor. The sensor mat slips under the mattress in your baby’s crib, and if it detects no movement after 20 seconds, it sends a loud alarm to the baby and parent units. Its touchscreen can be a little finicky. The Baby Delight is less prone to false alarms; however, our parent testers were concerned that the small clip-on sensor might be a choking hazard.
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.
