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.
Video monitors give a quick and silent look into baby's world without leaving your cozy bed or disturbing the baby. If a trip to the nursery is warranted, you haven't lost much time, but if the baby is just adjusting, then you can go back to sleep without getting up. Getting good sleep, or as much sleep as possible can be the difference between a great newborn experience and feeling like a new parent/zombie failure.
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.
As you’d expect, the talk back functionality and audio quality in general are great—easily better than the crude talk back features on our video monitor picks. With the battery lasting about 19 hours on a full charge, this monitor had the strongest battery life of any in our test (not entirely a fair comparison, as this is the only one with no screen to power). Rated to a range of 1,000 feet, it exceeds the range of our pick (700 feet) both as advertised and in practice during tests.
No ordinary monitor, the Cocoon Cam lets you see your baby and a graph that shows breathing patterns on your smartphone. The camera watches the rise and fall of your child’s chest and sends an instant notification if something seems off. You’ll also get alerts when your child has fallen asleep, is crying or is about to wake up. Since the Cocoon Cam live streams the video and audio over WiFi, you can watch your baby from anywhere.
The interface on the monitor, aka the parent unit, is basic, simple, and intuitive, while many of its competitors have awkward controls. When panning and tilting the camera, for example, the Infant Optics responds immediately and can move in very small increments. The text on the menu displays look like something off an old Motorola RAZR, but the commands are easy to interpret and less confusing than those of some competitors. A group of four buttons makes it easy to pull up the menu and make a change (to the volume, say) without losing sight of the image on the screen. Other nice minor touches, like a display that constantly notes the temperature in the baby’s room, appear on this model but not on all of its competitors. This is not a touchscreen, but frankly, if you’ve ever used an iPhone, you’ll find the touchscreens on most baby monitors to be sorely substandard.
The DXR-8 uses a secure 2.4 GHz FHSS wireless transmission to ensure privacy, gets up to 10 hours of battery life on a single charge, and can switch to audio-only mode with the camera off to save juice. That said, it has gotten panned for a quickly declining battery life (as well as poor range). Still, that hasn’t stopped 24,000 reviewers from giving it an overall 5-star rating on Amazon. In terms of bells and whistles, it features everything parents have come to expect in a monitor: invisible infrared night vision, (no annoying blue light to wake the baby) two-way intercom, room-temperature sensor, and the ability to work with up to four other cameras.
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.
