Today’s baby monitors will often come with a video feature or movement sensors, so you can know exactly what your baby is doing while they’re in another room (beyond just listening for any crying or fussing).

However, the traditional audio baby monitor is still a popular choice—and you have options.

Below we break down some of what’s available on many of the top baby monitors, and why you may want to consider them.

Volume sensors

If you opt for audio-only, you'll find that many come with lights that glow brighter as your baby cries louder.

You may like this feature because it makes it possible to know the urgency of their cries when you can't hear them, such as when you're showering, vacuuming or on the phone.

Digitally Enhanced Cordless Telecommunications (DECT)

Sounds high tech, doesn’t it? Well, it kind of is. One of the biggest complaints about baby monitors is that they often pick up interference or static from other electronic devices, such as cell phones or cordless phones. An effective way to avoid this problem is to choose a digitally enhanced cordless telecommunications (DECT) monitor. This type of monitor has less interference because it uses a newer, less congested bandwidth (sometimes they’re referred to as operating on a 1.9 GHz frequency). Since there are fewer DECT monitors for sale, they tend to be more expensive.


If you’re looking for the most affordable option, an analog baby monitor is the way to go. Analog monitors work best in sparsely populated areas. Before making your purchase, you should check to see which frequency your cordless phone or wireless network operates on, to minimize any interference on your monitor. Many analog baby monitors operate on 49 MHz, 900 MHz, or 2.4 GHz frequencies.
