To save on battery life, some audio/video models only turn on when the baby makes an unusual motion or sound. Some models come with a motion-detector pad that fits under the crib sheet. This type of motion sensor is intended to prevent SIDS. Sensitive enough to detect changes in breathing, an alarm sounds if there is no movement after 20 minutes. However, if the baby simply rolls off the pad, the alarm may sound.
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.
After testing more than half-a-dozen mounted cameras that beam live video from a nursery, the best baby monitor we've tested is Netgear's Arlo Baby. Netgear's baby monitor packs in a number of must-have features such as clear 1080p video, two-way audio and a host of sensors. Everything's easily accessible from a well-organized mobile app that puts the Arlo Baby's controls at your fingertips.
