Reliability. This is a tough one, as it requires long-term knowledge of system reliability, through thick and thin. There are many baby monitors on the market that start out excellent but tend to glitch out or completely fail within the first several months of ownership. This is especially the case for many unrecognized brand names that are saturating the market. If you're buying this as a baby registry gift the last thing you want to do is make the new parents think you cheaped out on a junky baby monitor! All of the best video monitors that make it onto our list have withstood the test of time, lasting at least 6 months, and in some cases several years at this point (like the Infant Optics option!). Another point about reliability that's worth mentioning is that most modern wifi baby monitors will keep a local connection to your app even when the internet is down. So as long as you're still in your house, you can continue streaming video even when the internet is down.
If you'd like the flexibility of having a dedicated handheld monitor for use in the home, while still being able to rely on your Internet network on a mobile device, the Peek Plus Internet Monitor System is worth looking at. The Peek Plus connects directly to your home wireless network for instant access. You can begin viewing the stream on the included handheld monitor or via a dedicated Internet browser or complementary smartphone app (for iOS, Android and Blackberry), or both. The secure Internet page of your baby's video stream gives family and friends the ability to look in on your baby as well.
Our hands-on reviews put 32 video baby monitors to the test, examining their features, image clarity (day and night vision), convenience, reliability, safety, the range of reception, and versatility.
