The longest battery life for the dedicated products in our review is the Levana Lila, which ran for 12.75 hours in full use mode. The manufacturer claims this unit will work up to 72 hours in power saving mode, but we only tested the monitors in full use. The Infant Optics DXR-8 came in second place with a shorter run time of closer to 11.5 hours. The Motorola MBP36S earned the lowest score for battery life with a runtime just under 7 hours. While not necessarily a deal breaker, there are plenty of other reasons to dislike the Motorola MBP36S, and the battery life is just a small part of a disappointing overall picture (no pun intended).
Poor quality and durability plague many baby monitors. Scores of reviewers on Amazon and other sites report that the Hello Baby HB32; Motorola MPB854Connect, MBP36XL, MBP33XL, MBP41, and MBP43; Infant Optics DXR-5; Summer Infant Dual View and Sure Sight 2.0; Levana Jena, Keera, Ayden, Astra, and Lila; Angelcare AC420; Philips Avent SCD570 and SCD630/SCD637; and VTech VM342-2 and VM343 don’t deliver on promised functionality and start to fail in some critical capacity within a year—often in much less time.
Features are important, but we encourage you to consider which features you think you will realistically use and which sound like fun in theory, but probably won't happen in practice. Many of the monitors carry a higher price tag and justify the price with the addition of features parents are unlikely to use in real life. Features like alarm clocks for feeding schedules, and alerts for low humidity might feel like something you should consider, but in practice, sound activation and quality images are more useful. In fact, more features often translate to being more difficult to use, and many of the features are novelty functions that most parents stop using over time. A good example of this is the Philips Avent SCD630 with an ease of use score of 8, but a features score of only 4. Try not to fall for the propaganda of bells and whistles that you might only use for the first few weeks. In the end, what you want is a good monitor with great sound and video quality.
Portable Base Unit with Good Range: Babies go to bed earlier than parents, and they also nap during the day. Unless you want to spend your time sitting next to the baby monitor base unit watching the video stream, you're going to want a unit that has far range and good battery life. This will let you take the unit and, say, take out the trash or let the dog out, while still being able to see your baby. Better yet, many of our best-rated baby monitors are completely wireless and operate by running iPhone or Android apps on your smartphone to wirelessly view the digital color video stream wherever you are. In this way, you're no longer buying a camera and monitor, you're only buying the same cameras that modern security cameras use. This gives you a more universal baby monitor and makes portable wifi baby monitoring more convenient than ever, and we're definitely in support of this new trend. Want to keep an eye on your child while you're on date night? No problem, but only with one of these modern systems.
Frequency: Some baby monitors operate on the same 2.4GHz frequency band as household products like microwaves, cordless phones, wireless speakers, and so on. When the monitor is on the same frequency as a number of other products, you can experience interference and static. You may want to get a monitor that uses a different frequency like 1.9GHz, which the Federal Communications Commission sets aside for audio-only applications. It's called DECT, or Digitally Enhanced Cordless Telecommunications.
If you want remote access to see footage inside your home while you’re away, why not just use an indoor security camera? If that’s your sole objective, we think such cameras are a better choice than a dedicated baby monitor—and we explain which ones we like and why, in detail, in our guide to wireless indoor home security cameras. But in comparing our picks here against the Nest Camera (a popular, mainstream option, and a pick in our security camera guide), we found that security cameras start to lose their appeal when you try to use them in the ways most people regularly want to use baby monitors—at home, at night, all night, while a kid sleeps. Many won’t stream audio in the background, which means that to continuously monitor your baby, the app has to be open at all times. Some can take several seconds to pull up a live feed—not ideal when you want to see why a baby is crying. They can work well if you’re traveling and want to see what the family is up to, or if you’re out for the night and want to check on the kids without bugging the sitter—but as useful as that capability is, we concluded that it really is a different task from what most people want to accomplish with a day-to-day monitor.
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.
