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Night Vision: When wireless baby monitor systems with screens were first introduced onto the market they used somewhat outdated display technology that made for a grainy, distorted and often unreliable picture.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!
Many of the baby monitors we've tested are internet-connected, letting you watch infant with your phone or tablet through an app just as if you were checking a home security camera. Because of this, you might not actually get a standalone display to go along with the camera. They aren't out of the question, however; some camera-only baby monitors offer viewers as an add-on or in a bundle. And if there aren't any available, you can simply get an inexpensive tablet like the Amazon Fire to use as a dedicated viewer.
