Clarity of Daytime and Night Vision: When wireless baby monitor systems with screens were first introduced onto the market they used somewhat outdated display technology that made for a grainy, distorted and often unreliable picture. Newer baby monitors use a liquid crystal display similar to the ones used in your smart phone and other consumer electronics, so these HD video baby monitors tend to have very nice color contrast and high resolution, and are also substantially more reliable. All of the stand-alone baby monitors we list above have high-quality displays, and we do not recommend some of the relatively old fashioned ones that can still be found on the market. Of course, night vision doesn't use color - so the display will be either grayscale or show a slightly green hue. That's important to keep in mind before you try it out for the first time; not even military special operations have color night vision, so don't expect anything amazing, even from the best baby monitor!
When shopping for a video monitor, note that you'll pay a substantial premium over audio-only monitors, which cost around $30 to $50. You'll need to decide if the extra money for video viewing is worth it, though parents may appreciate the ability to glance at a smartphone app or handheld monitor to visually check in on their sleeping child instead of opening a door and potentially waking up their baby.
Dropped connections are another problem. "We tested our Wi-Fi monitors on two separate routers and consistently had problems -- we'd often lose the connection some time in the night and not even realize that the monitor had disconnected until morning," Wirecutter says. "This happened with all three Wi-Fi models we tested. We never really felt confident relying on any of the connected monitors overnight, despite the fact that the modem and router were literally on the other side of a wall from the monitor."
Though it’s not a video monitor, the Owlet does track your baby’s heart rate and oxygen while they sleep, and notifies you if something appears to be wrong. Just slip a comfortable wrap with a sensor over your wee one’s foot (it works with babies 0–18 months) and download the app to your phone. You’ll receive alerts in real-time should your child’s vital signs change. It also comes with a base station that changes color when something is up.
Bargain hunters may prefer the iBaby M6T. Though it's a couple years old and records video in in 720p resolution, it's still a capable monitor with night vision, two-way audio and helpful pan-and-tilt capabilities. It's also available for nearly $100 less than the Arlo Baby. If the voice-powered Alexa assistant is a part of your family, consider the Project Nursery Smart Baby Monitor, which includes a smart speaker in its $229 bundle that lets you remote control the camera.
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.
As you'd expect, the talk-back functionality and audio quality on the VTech are great—easily better than the rudimentary talk-back features on our video monitor picks. With the battery lasting about 19 hours on a full charge, this monitor has the strongest battery life of any in our test. Rated to a range of 1,000 feet, it exceeds the range of our pick (700 feet) both as advertised and in practice during tests.
The DXR-8 packs a lot of punch for the price, including a sound-activated 3.5-inch full-color LCD screen, crystal clear video quality, and an impressive 270-/120-degree pan and tilt range ⏤ controlled remotely, of course. It’s also the only baby monitor on the market to include interchangeable lens for advanced zoom and wide-angle shots, in case the only good spot to set up is across the nursery from the crib.
However, a closer look at the flaws noted in the iBaby’s negative reviews—currently, one-star reviews make up roughly 25 percent of the total—pushed us even further toward the Infant Optics as the one we’d choose for a similar price. The app is pretty poorly done. You may lose a connection even with a perfect Wi-Fi signal. Some people report never being able to connect to it at all. The plug on this unit is an odd 2-piece design that is unnecessarily complicated (but it can be fairly easily replaced with another basic 5V charger if you want). All told, the M6S comes close to the functionality of the Infant Optics pick in some ways, and the ability to access the camera remotely is a huge plus, but all the other drawbacks are too much to overlook.
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.
