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.
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.
At over $200, are advanced audio/video monitoring systems with multiple cameras and receivers with large screens, as well as the ability to connect to several mobile devices. While they are loaded with features, it’s important to look closely at the audio and video quality. Expensive monitors are just as susceptible to interference as inexpensive ones.
Why spend money on a baby monitor, which serves a single specific purpose, when you could use an indoor home-security camera that you can repurpose once your kid leaves the nursery? We wondered the same thing, so along with with dedicated video baby monitors, we tested a Nest Indoor Cam, currently among our top-rated wireless home security cameras.

While you plug the camera in to power it, you can also detach the camera and move it into any room where an impromptu nap occurs, though we only saw three hours of battery life when we tried this out.
The baby monitor market is really exploding with new high-quality options that use a wifi camera connected to an app on your smart phone. The Nanit smart baby monitor is a new addition to this market, and we're really excited about it! We got our hands on this baby monitor for testing in mid-2018. Out of the box, the system is really well designed and made with high-quality components. The camera itself looks sleek and modern, similar to the Lollipop baby monitor. Like the other wifi baby monitors on this list, the Nanit streams high definition (HD) digital video and digital audio right to an app on your phone, and the app is available for Android and Apple devices, including phones and tablets. It does this by connecting to your home's wifi and streaming video right through your existing router. In our testing, we found that if you're at home the video streaming is very fast (low latency) and high clarity. And if your internet goes down, it will still work as long as you're still connected to your home wifi. On a 4G LTE connection, the video is a bit choppy from time to time but we found that a common theme with any wifi-based camera system. Let's first talk about some of the features. First, there is an awesome digital zoom feature right from your app - you pinch the screen just like with anything else and get a clearer view of your baby. Second, it has temperature and humidity sensors so you can keep track of nursery conditions. We compared the temperature and humidity readings to our hygrometer and it was very accurate. Third, we loved the wall-mount because it gives you a really nice overhead vantage point on your baby, unlike some of the standing cameras that sit on a nearby surface - this has a much better view. Note that if you want to mount it on a nearby surface like a dresser or changing table, you can buy a separate Nanit table mount. Fourth, it includes the wall mounting hardware and the cord hiding strips to keep the wires out of baby's view and reach. Fifth, the camera quality was excellent in both day and night vision conditions. Finally, there are some other nifty features, like the ability to receive alerts for sound or motion, to have audio running in the background of your phone (which is great for nighttime), a nightlight that you can control right from the app, and encrypted communication. So that's all excellent, and when you combine it with the monthly subscription ($10/month) for Nanit Insights, it's a great package that not only monitors but also can track your baby's sleep habits (including videos). A 1-month trial is included for this service so you can check it out and see if you want to consider - we suspect that most parents will be content with just the real-time monitoring without any habit tracking. In our testing, everything worked really well, and we were consistently impressed by the streaming video and sensors. The biggest drawback for this monitor is the price - it's about $250, which is up at the top of the price range for this entire list. We'll let you figure out whether it's worth the cost for your specific needs. Update: we have now been using this Nanit baby monitor for just over 3 months, and we continue to be very happy with it, it seems to be not only high quality but also reliable (so far!).

How far away baby's monitor can be from the parent unit is what determines a product's range. While many manufacturers offer a "line of sight" range to describe a monitor's range, it is not a good indication of how well it will work in your home with walls and interference. It doesn't matter how much you like a specific model or brand, if it doesn't work in your house, it simply isn't going to work. We tested both indoor range and open field tests to provide the best information, but remember that the values inside your home matter more than those in an open field, unless of course, you are leaving a baby alone in an open field (which we don't recommend).
