Movement products are designed to sense the movement associated with a baby breathing. These products attempt to discern when your little one has not moved within a prescribed period that could indicate that they have potentially stopped breathing. While this may seem like a no-brainer option for parents worried about Sudden Infant Death Syndrome (SIDS), they are not foolproof, have not been approved by the FDA as a medical device, and are known to have false alarms where the baby is fine but then suddenly awakened by a loud alarm. While it is an interesting kind of product, we caution parents that this type of device is not a substitute for safe sleeping practices and doesn't prevent SIDS. However, if you are willing to accept false alarms, it can provide another layer of monitoring to help some parents sleep better at night. Movement sensing products are only useful until babies start to roll over, at which point they become unreliable.
The DM111 is a basic bare-bones sound option that does exactly what a sound product should do. It relays the sounds from your baby's room to the parent device with no muss no fuss and good sound quality. With a simple plug and play design, it is hard to mess up making it a great choice for parents who aren't technology savvy or for grandma who might find more complicated products frustrating. This product is the cheapest option in any of our reviews for monitoring products, but you won't be sacrificing sound quality or usefulness for the price.
Video, Audio, or Both: First-time parents are suckers for high-definition, night-vision baby monitors where they can pick up on exactly how their child’s chest is rising and falling. You will do this dozens of times a night. Past the Sudden Infant Death Syndrome-scare age, you may just want an audio baby monitor (which a lot of video ones double as), because you’ll know an “I’m hungry” cry from an “I lost my sock” whine.
Baby monitors are available in three primary forms: audio, video and movement. If your main concern is hearing when your baby wakes up, then an audio-only monitor will do the trick. These baby monitors tend to be smaller, and less expensive. With a video baby monitor, there are a wide variety of options available, including different screen sizes, cameras that tilt, pan and zoom, and night vision. This type of monitor tends to provide extra levels of security, allowing you to tell if your baby is lying down or standing up, to track sleep patterns, and to evaluate whether intervention is required, or whether your child seems likely to self-soothe and fall back asleep. Plus, if you get a video camera that connects to your Wi-Fi, you can use the camera as a nanny cam, and check the baby video even when you're away from home. Movement-based baby monitors are designed to track your baby's heart rate, movement, respiration, skin temperature and sleep quality.
Watching your child from moment to moment is far more important than going over footage from previous nights, so baby monitors don't usually make a big deal about saving video for later, whether using built-in storage or through a cloud service. They can take snapshots and short clips when they detect movement, but they won't offer time-lapse videos of entire nights at once, or let you page through hours or days of footage. Those features are useful for identifying burglars, but they don't really help you watch your child unless you're in a Paranormal Activity sequel.
Sound devices relay what is happening in baby's room via sound only. A great sound option is quiet unless the baby is making noise so that you won't be disturbed by white noise or constant static. This basic monitoring type can be all you need if your goal is being alerted when your baby is crying and needs your assistance. This style can be elementary with sound only like the V-Tech DM111 or it can have bells and whistles like a nightlight, 2-way talk, lullabies, and mic sensitivity adjustment features like the Philips Avent DECT SCD570/10. Most parents can get by with a sound only device as it provides the information you need to determine if your baby needs you or not.
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.
