You might see monitors on the market with claims that they can track a baby's breathing or movements, but unless the unit is registered with the FDA, it's not a medical device. Consumer Reports hasn't tested this type of monitor. Talk with your pediatrician if you think your child has a condition that warrants medical monitoring. He or she can give you advice on the best devices.
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Night Vision: When wireless baby monitor systems with screens were first introduced onto the market they used somewhat outdated display technology that made for a grainy, distorted and often unreliable picture.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!
We took these criteria into consideration, factored in user feedback and reviews from across the Web, and eventually narrowed the list to eight cameras for testing. We used each camera for several months, taking notes on the interface and any difficulties we ran into. We connected each model to multiple routers, and used each from various distances and through walls to test range. We also ran each monitor from a full charge down to zero to check battery life. Finally, we evaluated each monitor's night vision in dark environments. Read more about our tests in our full guide to baby monitors.
We tested and compared 9 of the most popular video monitors in this review using a comprehensive series of tests with continued use over several months. Our tests were designed to provide you with the information you need to make an informed decision on which product is right for your family and needs. Each monitor is scored based on performance experienced during our hands-on, side-by-side testing process. The test results determine the metric scores, and those scores combine to create overall scores and rank. Metric scores are derived from our in-house lab and user experience "in the field." Overall scores were weighted with a preference for the range, video quality, and sound clarity.
Reliability. This is a tough one, as it requires long-term knowledge of system reliability, through thick and thin. There are many baby monitors on the market that start out excellent but tend to glitch out or completely fail within the first several months of ownership. This is especially the case for many unrecognized brand names that are saturating the market. If you're buying this as a baby registry gift the last thing you want to do is make the new parents think you cheaped out on a junky baby monitor! All of the best video monitors that make it onto our list have withstood the test of time, lasting at least 6 months, and in some cases several years at this point (like the Infant Optics option!). Another point about reliability that's worth mentioning is that most modern wifi baby monitors will keep a local connection to your app even when the internet is down. So as long as you're still in your house, you can continue streaming video even when the internet is down.
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.
