There are two basic types: audio and video/audio. Some are analog, others are digital. All monitors operate within a selected radio frequency band to send sound from a baby's room to a receiver in another room. Each monitor consists of a transmitter (the child/nursery unit) and one or more receivers. Prices range from about $25 to $150 for audio monitors and about $80 to $300 for audio/video monitors.

Eufy, a company known for its robot vacuum cleaners, is branching into baby monitors with the new $135 Security SpaceView monitor. The monitor comes with a handheld display featuring a 5-inch LCD screen and enough battery power to let you check in on the nursery throughout the day. We're waiting to get our hands on the Security SpaceView camera, but with 330-degree tilt and 110-degree pan, it sounds like there's little that will escape the 702p camera's view. Other features include night vision, noise alerts and two-way talk. Stand by for a full review.


The time you use your device depends on your needs and what type of device you choose. Movement products have the shortest lifespan and only work up to about 6-9 months old or when your little one starts rolling and moving. Sound and video options can be used for years depending on your needs. Video products can arguably be used for the longest period because it can help you keep tabs on older children as they nap and play. Wi-Fi options have the most extended use as they can also keep an eye on a nanny or work for security purposes. The Nest Cam is designed for security use and can be used for years to come in lots of applications. If the duration is a top concern for you, then the Wi-Fi video products, like the Nest cam or LeFun, should be your go-to choice.
With a baby monitor, you're able to keep tabs on your little one(s) during nap time or nighttime, and still go about your day. Generally, the number one benefit provided by the best baby monitors are peace of mind, followed closely by the benefits of security and convenience. Plus, since homes and habits vary, a baby monitor may have additional uses, like allowing you to monitor how long it takes your preschooler to fall asleep, keeping track of playtime, or even using it as a pet cam.
This type of monitoring device attaches to your baby via their diaper, clothing or as a sock depending on the model. Most of the wearable options alert in the room and only a handful send a message to a parent device (smartphone or similar). In our experience, many of these have high false alarms from moving and crawling babies or high Electromagnetic Field (EMF) Levels (which we try to avoid). The Snuzo Hero SE is a cost-effective wearable with a unique vibration feature and very low levels of EMF.
To test connectivity, we put the handheld unit and the camera in neighboring rooms with 30 feet between them. We looked for lag, choppiness, and changes in the video or sound quality. While we rated it separately, we also did tests to estimate each baby cam’s maximum indoor range. Each camera we tested has a range of 100 feet or more, which is enough for an average-size home.
A word of caution about extremely cheap baby video monitors (we're talking devices that cost less than $50): they're not known for their security and can be hacked. Be sure to always change the default password of any connected device you purchase. You can also protect yourself by sticking to known vendors who post frequent firmware updates and have easy-to-reach customer support.
The Levana Lila video product is a dedicated camera and parent unit which means you don't need to tie up your personal device or use the internet. This option is user-friendly and has a respectable range that could work for most average size homes. The Lila has long-lasting battery life and a reasonable price with fewer features than much of the competition, but that is part of what makes it easy enough for grandma to use.
The Arlo Baby camera, which comes dressed as an adorable green bunny, connects to your wireless internet and connects to your phone via the associated app. It streams 1080-pixel video footage, even at night, and has an 8x zoom to let you see exactly what’s going on in the nursery. There’s a two-way talk feature, night light and smart music player, as well as an air sensor and baby crying alert, letting you keep a watchful eye on your little one.

Gone are the days of silently peeking into the nursery to check on your napping baby and then, whoops, accidentally waking them up (“No, no, please no!”). A baby monitor uses a camera to watch over the crib, while you carry a handheld device that lets you know what’s going on with your child at any given moment, no matter where you are in your home. There are also other monitors that track sleep or breathing either with a clip or sock.
