Most connected baby monitors are effectively just home security cameras, like the Nest Cam Indoor—devices that let you watch another location with color video, night vision, and sound, so you can tell if anything is amiss. Because baby monitors are used to keep an eye on your little one rather than on your home and property, they prioritize different features than security cameras.
Baby monitors are just one way to keep track of your little one. For newborns, the Snoo Smart Sleeper is a bed that gently rocks your baby for better sleep, and connects to an app on your phone that lets you receive alerts when your little one needs attention. The Owlet Smart Sock 2, meanwhile, is a connected pulse oximeter that allows you to check on your baby's vitals any time through an app, and will notify you automatically if there's a problem. The Sproutling from Fisher Price is a motion and heart rate sensor that straps to the back of your baby's calf and collects data while he or she sleeps.
This is a criticism of the Amazon page more than of the product. It seems that most (all?) of the reviews are labeled as being for the various Pi 2 kits, but are in fact for earlier versions of the kits (Pi B and Pi B+) which had different kit components. The Base kit used to contain a case apparently so there are reviews labeled "Basic Pi 2 Kit" discussing the case and I was expecting a case when the Basic kit arrived.
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.
