There are two basic types: audio and video/audio. Some are analog, others are digital. All monitors operate within a selected radio frequency band to send sound from a baby's room to a receiver in another room. Each monitor consists of a transmitter (the child/nursery unit) and one or more receivers. Prices range from about $25 to $150 for audio monitors and about $80 to $300 for audio/video monitors.

As much as new parents want to be in the room with baby at all times, sometimes a baby monitor is necessary (like when you’re having a dinner party — or just want to watch Insecure in the next room). To help navigate the vast, confusing universe of baby monitors, we spoke to Lauren Kay, the Bump’s deputy editor, and Dave Baldwin, Fatherly’s former gear-and-tech editor and current play editor, about their recommendations, from traditional video monitors to smart-tech-enabled devices that can even track how your baby is sleeping. Add one of these to the baby registry.


iBaby makes a really confusing range of baby monitors. From cheapest to most expensive this includes the iBaby Monitors M2, M2S, and M2 Plus, iBaby M6, M6T, and M6S, and the new iBaby M7. The M2 series is usually under $100 and is pretty poorly reviewed overall. The M6 series is usually about $125 and is decently reviewed. Finally, the new M7 is brand new and only differs from the M6S in that it has a smell detector and night sky projector that can shine the moon and stars onto the ceiling (our review of the M7 is above). There's truly a lot to love about the iBaby M6S. It looks great, is pretty easy to setup, and has a ton of appealing features. Some highlights are that it uses 1080p high definition video, it senses room temperature and humidity levels, has an air quality sensor (measures the presence of volatile organic compounds or VOCs in the nursery), is dual band wifi compatible (2.4 and 5GHz), and a two-way intercom. It also can record HD videos, remotely pan (rotate) and tilt up/down, and you can setup alerts for motion, sound, and VOCs (from 1 to 4 with 4 being best). So it basically has everything that might be on your list of baby monitor essential features, and we were really excited to set it up. Out of the box, we found it easy to download the app to our smart phone (Android or Apple), connect to the monitor and connect it to wifi, and get things up and running. A couple notes here - first, your wifi password needs to be shorter than 32 characters or the app won't accept it, and second, there is no way to manually set an IP address for the camera. When we used it on our home wifi network, we found that the images were clear and decently fast (low lag), and the night vision was high-quality and not too grainy. We especially liked the pan and tilt features from the app, which allows you to move the camera's view angle around without going into the nursery (and it uses a cool screen-swipe gesture to do it). Once we left our home's wifi connection and tried to connect to the camera from a 4G LTE or a different wifi network, that's when we started to run into problems. It was choppy and laggy, which to be honest is what we expected when attempting to stream 1080p HD video outside of your home network. So we changed the resolution settings on the app (Settings - Display Settings - Resolution) to downgrade it to a lower quality stream; that seemed to help a bit. We also had difficulty connecting to the camera at times, whether we were at home or elsewhere, which was one of the more frustrating things about the iBaby Monitor M6S. The temperature and humidity sensors seemed to work pretty well, and we confirmed their accuracy with a separate thermometer and hygrometer (they were pretty decent in accuracy). For the two-way intercom, the speaker in the camera seemed pretty poor quality so it was hard to hear my voice when attempting to speak to (or sing to) our baby. Finally, we had some issues with alerts coming through to the app as intended. We setup the temperature, humidity, and VOC alerts, and had really intermittent alerts when we tested them out. The temperature and humidity sensors seemed to be reading just fine, they just weren't reliably triggering an alert when they deviated from a range. For example, we set a temperature alert for 80 degrees then blew a hair dryer at the camera; it warmed way up, but the alert wasn't triggered, so that was frustrating. We didn't test the VOC sensor, though one could imagine you could open up a can of paint next to the camera and see if it sends an alert. So overall, we have a decent wifi baby monitor that has some excellent features but also leaves a lot to be desired in the reliability department. Interested?

The Nanit Smart Baby Monitor is for the tech- and data-obsessed parent who wants to know and track everything about his baby. Winner of the Bump’s 2018 Best of Baby Awards, the Nanit is an over-the-crib Wi-Fi camera that not only offers standard video monitoring capabilities, but also provides sleep insight reports and sleep scores via the app. The bird’s-eye-view camera provides real-time HD-quality video and uses “computer vision” to track whether your child is awake, sleeping, or fussing. Then, Nanit synthesizes this data to generate nightly sleep reports and sleep scores, even providing tips on how to help your baby sleep better. Says Kay, “The Nanit is a two-in-one in that you’ve got this monitoring app, but you’re also getting helpful training and guidance when it comes to sleep, which is different from a lot of the competitors.” Priced at $279, it’s definitely on the high-end of baby monitors, but if that extra functionality is important to you, it may be worth it. For other parents, however, the Nanit may be more than you need.
For the parent devices of dedicated monitors, the battery life ranged anywhere between 6.75 and 12.75 hours. The Wi-Fi options are harder to gauge given that the battery life depends on the kind of device used, whether or not it is being used for other applications simultaneously, and how old the battery is in the device. In general, however, we feel it is relatively safe to say that most will work longer than the best dedicated monitor battery if the device is dedicated for use with the monitor only and is not running other applications simultaneously.

The main reason you’re going to need a baby monitor is to answer a simple, but time-honored, question: Why the hell is my baby crying? It’s only been in the last 30 years or so that parents have relied on the remote surveillance of their sleeping children. For the eons before that, it was a combination of natural, ear-piercing cries, and sleeping in the same yurt.
It really depends on what you feel most comfortable with. There are audio monitors that allow you to listen to any noise coming from the nursery, vital monitors that track sleep and breathing and video monitors that add sight to sound. Babylist parents overwhelmingly choose video monitors. The security of seeing what your child is up to—like if they’ve gotten tangled in their swaddle, pulled their diaper off or climbed out of the crib—can be worth the extra cost of a video monitor.
