When shopping for a video monitor, note that you'll pay a substantial premium over audio-only monitors, which cost around $30 to $50. You'll need to decide if the extra money for video viewing is worth it, though parents may appreciate the ability to glance at a smartphone app or handheld monitor to visually check in on their sleeping child instead of opening a door and potentially waking up their baby.

In terms of bang for your buck, it’s tough to beat the Babysense. For less than $100, it comes loaded with bells and whistles more commonly found on higher priced models. Not only does it boast a 2.4-inch HD LCD color screen with infrared night vision, pan/tilt, and 2x zoom, but it includes two-way talk back, a sound activated ‘Eco’ mode (the screen stays off) to save battery life, 900 foot range (with out-of-range warning), and an in-room temperature monitor that sends alerts if it gets too hot or cold. It uses 2.4 GHz FHSS wireless transmission for security and even comes with both a built-in alarm/nap timer and lullabies.
The best baby monitor apps allow you to monitor baby using only your existing devices, like phones, tablets or even computers. One device acts a transmitter in baby’s room, and you use another device to monitor baby. Some apps only have audio functionality, but others have both audio and video. As a plus, the best baby monitor apps often have cool features that traditional baby monitors don’t have, like remote capabilities. However, some users complain that they can be somewhat unreliable.
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.
Encrypted Wireless Communications: Here's something creepy and strange - there are reports of people tapping into even the best baby monitors and getting some bizarre pleasure from watching your baby sleep or watching you feed the baby in the middle of the night. A few of the manufacturers have included wireless encryption on their systems to make this much less likely.
Some audio/video monitors filter out "normal" sounds and motions. The receiver is supposed to turn on only when your baby makes an unusual motion or sound, such as crying or rolling over when he's waking up from a nap. This feature is designed to extend battery life, although the receiver should be docked for overnight monitoring to keep the battery charged. We haven't tested any models with this feature, so we don't know how well it works.
The Nanit couldn’t be more perfect for analytical types. The camera—when placed just so—uses computer vision to watch your baby’s every move, and then tell you what it means. You get a notice on your phone, which acts like a handheld monitor, when your child is awake, acting fussy or has fallen asleep. The Nanit also assigns a sleep score to each night based on how many hours your child was actually crashed out. Other stats include how many times you went into your child’s room and how long it took for your little one to fall asleep. Because the Nanit streams live video and audio to your phone, you can also check in on your kiddo when you’re away from home. It also has a nightlight and temperature and humidity sensors.
