While the price is too high compared with our other picks to merit a recommendation, the Arlo Baby by Netgear Smart HD Baby Monitor and Camera does have some appeal, mostly because it overcomes some of the traditional shortcomings of Wi-Fi monitors and security cameras used for that purpose. Its main advantage is that its app can continue to play audio even if the app is not open in the foreground of your mobile device. This means it can continue to broadcast sounds from a baby’s room while parents sleep elsewhere, alerting them if there’s trouble (as a traditional monitor would), without the hassle of loading the live stream every time. It also offers some unique features: The camera itself can work wirelessly off a rechargeable battery (which no other monitor we’ve tested can do), and it can track and chart several days’ worth of temperature and other environmental data in a child’s room. These features alone don’t justify its added cost—the current price is about $100 more than that of either our pick or the least-bad Wi-Fi monitor we’ve tested—but that cost may be easier to swallow if you’re already using other Arlo devices, which we began recommending as a runner-up in our piece on indoor security cameras in fall 2016. As with most Wi-Fi monitors, owner reviews note problems with the signal dropping out, sluggish response time when opening the video on an app, and other irritations, such as problems seeing the feed on multiple devices.

So we recommend choosing a baby monitor that uses a different frequency band from your cordless phone and other wireless products in your home. The band that your cordless phone operates on should be printed somewhere on it. Remember that interference can vary widely depending on where you live, the electronic devices you have at home, and the ones your neighbors have. If, for example, you have a 2.4 GHz wireless product, such as an older cordless phone, choose a baby monitor that doesn't operate on the 2.4 GHz frequency band. People with newer phones that use DECT will have fewer issues with interference.
Microphone sensitivity: There’s a difference between hearing your baby cry, and hearing every little noise. All baby monitors have the option to turn down the volume, but some offer thresholds for parents who are more comfortable with only hearing the biggest upsets, and prefer not to hear the self-comforting noises their baby makes as they fall asleep.
If you sleep in the same room as your baby or live in a small enough space that you can always hear or see what your baby is up to, you probably don’t need a monitor. Otherwise, most parents enjoy the convenience a baby monitor provides—instead of needing to stay close to the nursery or constantly checking on your child, you’re free to rest, catch up on Netflix or get things done around the house during naptime. Monitors can also double as a nanny cam to keep an eye on your child and their caretaker.
