Beyond that, we wanted to hear from an expert on the products’ (perceived and real) security risks. So we spoke to Mark Stanislav, the director of application security for Duo Security and the author of Hacking IoT: A Case Study on Baby Monitor Exposures and Vulnerabilities, whose research has been featured in The Wall Street Journal, The Associated Press, CNET, Good Morning America, and Forbes.
You might prefer one that has lights as well as sound. All the audio monitors we rated had this feature. The Philips Avent DECT SCD510, which sells for about $120, has a series of small LED lights on the parent monitor. The louder the sound in your baby's room, the more lights go on, so you'll notice his crying even with the unit set on mute. Audio monitors are generally less expensive than audio/video models.
Once you've settled on a type and have considered your range, you can look at the potential choice and which features they have. The more budget-friendly choices usually lack bells and whistles but are still functional. If you want more features like nightlights, lullabies, and talk to the baby, then you may pay more and the unit could be more difficult to use. The one feature we think is important is sound activation to help keep your device quiet when your baby is quiet, thereby increasing your chances of a full night's sleep.
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.
Wi-fi baby monitors are the latest innovation in high-tech baby gear, and they’re super convenient. A baby monitor with wi-fi allows you to connect anywhere that has Internet service or Bluetooth capability, and the monitor can often be controlled remotely using a smartphone or computer. This functionality makes the wi-fi baby monitor great for travelling (unless you’re heading to a remote location). Safety tip: No matter what connection you use, be sure that it’s a secure connection in order to prevent your monitor from being hacked.
We have been following news that the Amazon Echo Spot, available in December 2017, can work as a baby monitor. While we plan to test these claims firsthand, our initial interview with Amazon confirmed a few hunches, and we believe certain shortcomings will make the Echo Spot hard to recommend as a baby monitor. First, it’s not a “baby monitor” per se; the Echo Spot will project video from an existing home security camera or other Wi-Fi camera through its screen. This approach has a few disadvantages, which we outline in the What about a Wi-Fi baby monitor? section. Amazon also confirmed that the Echo Spot would broadcast the same footage you would see on that camera’s app, and that it would not work as a display for RF monitors, like our pick in this guide. The Spot can use voice commands (for example, “Alexa, show me the nursery”), and we’ll determine in testing if that capability overcomes a common flaw in other Wi-Fi monitors and security cameras, namely a sluggish response time when loading video over a standard app. You can also “drop in on the nursery” to hear audio, and potentially talk back, depending on the camera’s functions. As with the voice function, the ability to see the temperature of the baby’s room, plus pan/tilt, play music, and other functions, will be dependent on the camera the Echo Spot is attached to.
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.
