As with any internet-connected device that watches or listens to your home, it's not out of the ordinary to be somewhat wary of a smart baby monitor. All Internet of Things (IoT) devices are potential soft spots for hackers to monitor you. Anything you network can possibly be compromised, and while you shouldn't be afraid of an epidemic of camera breaches, you should always weigh the convenience of these devices against the risk of someone getting control of the feed.
Notifications and alerts work by sending a message or email to your device when motion or sound has occurred. This feature is only found in the Wi-Fi monitors, and isn't the best feature for baby because it comes after the fact (sometimes up to 30 min or more after), it does not offer details of the type of sound or motion detected, and could get annoying with useless and excessive messages being sent. In the end, we prefer sound activation over notifications and feel that alerts and notifications aren't all that useful for keeping tabs on your baby.
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.
This monitor offers lots of convenient features. Don’t have the best view of your baby? Use the monitor to remotely pan, tilt or zoom the camera without having to go back into the nursery. Fussy baby? Press a button to play lullabies. Need the camera to move from your bedroom to the nursery? No problem: this freestanding monitor can be set on top of a dresser or grip onto shelves and brackets. You can also unplug it and use it in another room for up to three hours on a single charge. And there’s a room temperature display. But the most impressive feature is its 1,000-foot range—the highest of all cameras on this list. That means you can hear your little one’s every chirp even if you’re hanging out in your backyard.
