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.
We tested monitors daily over a period of several months, in three houses: one nearly 100 years old with plaster walls, plus a newer home with standard drywall construction, and a two-level 1960s home with a driveway on another level from the kids’ rooms. We tried the cloud-based monitors with two routers to be sure that any connection issues were with the monitors themselves and not the Internet connection.
iBaby currently works with iOS devices and provides parents with instant video and audio monitoring of their baby from wherever they are. As long as you're connected to the Internet, either via a Wi-Fi or 3G/4G network, and have the complementary iBaby Monitor app installed, you can pan and tilt the monitor to get a better view, and use the built-in audio feature to speak to your baby and offer gentle shushes if she starts to rouse. There is even a motion and sound detector that will alert you, based on the level of sensitivity you've selected.
The range of a product can make or break whether or not you can use certain options in your home. Depending on the distance from your room to the baby's nursery and the construction of your home or interfering appliances, you could be limited in your options of what will work for you. If your house is large or has more than a handful of walls between the two room, you'll be stuck with a Wi-Fi option only (assuming you have Internet). If your home is smaller or has fewer walls, then you'll have more options. Many of the wearable movement choices work in the baby's room and are not dependant on communicating with a parent device. However, if your room is out of earshot, then you'll never hear the alarm go off making the unit virtually useless without a sound monitoring addition. Choose your product carefully if you think the range will be an issue and purchase from retailers like Amazon that have a generous return policy. Also, don't let it sit in the box, try it out right away and send it back immediately if it doesn't work in your space. Do not rely on the manufacturer's range claim, as we have found these claims to be wildly inaccurate for many brands during our testing.

If you want to know everything about your baby, down to the heartbeat — the Angelcare AC315 is our top motion-sensor monitor. The sensor mat slips under the mattress in your baby’s crib, and if it detects no movement after 20 seconds, it sends a loud alarm to the baby and parent units. Its touchscreen can be a little finicky. The Baby Delight is less prone to false alarms; however, our parent testers were concerned that the small clip-on sensor might be a choking hazard.
This unit only works until little ones can roll or crawl. It can be uncomfortable for some babies or ineffective if little ones are too small or their diapers don't fit well. We worry parents will rely on this kind of device to prevent SIDs and caution you that there is no evidence that it does or can prevent the incidence of SIDs. However, if you want to know when your little one is moving at a predictable rate, and knowing may help you sleep better, then the Snuza could be the right option for you that won't break the bank or require adjustments to your nursery.
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.
The Nest Cam isn’t a dedicated baby monitor, but an all-around home protection device. Besides aiming the camera at the crib, you can also use it to keep an eye on the nanny, the dog or your empty home while you’re away. The video camera can be set up anywhere, and you can watch the live streaming from your smartphone. It also has two-way communication so you can soothe your little one to sleep, even if you’re offsite. If the device senses motion or sound, it’ll send a phone alert or an email to you. Missed what happened? From the app, you can view photos of any activity that took place over the last three hours. (There are Nest Aware subscriptions available that provide access to 5, 10 or 30 days of recordings, for $5, $10 or $30 a month, respectively). The picture quality is super sharp, too.
