If your internet goes down, your baby monitor goes down. A wifi baby monitor uses your home's internet connection to communicate to servers, then to your app. So if your internet connection goes down, then you will no longer be able to stream video of your baby. That's a huge consideration to keep in mind because you never know when your internet will slow down or simply stop working for several minutes or hours, and you will be stuck without a working baby monitor. There are a few wifi baby monitors that will still communicate locally (within your home's network) when the internet goes down, such as the Lollipop or Nanit. They do this by switching from internet to local area network when an outage is detected, so you can have confidence that if you're connected to your home wifi you'll still see your baby.

Security: Whether you’re skeptical of people hacking baby monitors or deeply concerned about it (and there are stories!), the bottom line is that some monitors are at more risk than others. A Wired story from 2015 refers to security firm Rapid7’s findings that Wi-Fi–enabled monitors were particularly vulnerable. We figured people would prefer the not-hackable type, and we talked to a security expert about how to protect your privacy.
The iBaby M6S Wi-Fi earned a 9 of 10 for features in our tests. This monitor offers features that increase convenience for parents and things that are fun for baby. For parent convenience, this camera works on any iOS device, can be accessed from anywhere with internet or cell phone reception (with a data plan), will work with multiple cameras, and has sound activation. The user interface is intuitive for experienced iOS users, and the zoom/pan/tilt features work well. This monitor features a true remote-controlled camera with the widest field of view range in the group, motion detection, sound activation, and it has built-in remote-controlled lullabies that include the ability to add your music of choice or your recorded voice. The iBaby M6S also monitors the temperature, humidity, and air quality of baby's room so parents can ensure baby is comfy and cozy. If all that wasn't enough, the app will remain running when using other apps, and when parents turn the device's screen off. Possibly the only things lacking are an automatic screen wake and sleep, which we think isn't that big of a deal.
Portable Base Unit with Good Range: Babies go to bed earlier than parents, and they also nap during the day. Unless you want to spend your time sitting next to the baby monitor base unit watching the video stream, you're going to want a unit that has far range and good battery life. This will let you take the unit and, say, take out the trash or let the dog out, while still being able to see your baby. Better yet, many of our best-rated baby monitors are completely wireless and operate by running iPhone or Android apps on your smartphone to wirelessly view the digital color video stream wherever you are. In this way, you're no longer buying a camera and monitor, you're only buying the same cameras that modern security cameras use. This gives you a more universal baby monitor and makes portable wifi baby monitoring more convenient than ever, and we're definitely in support of this new trend. Want to keep an eye on your child while you're on date night? No problem, but only with one of these modern systems.
However, a closer look at the flaws noted in the iBaby’s negative reviews—currently, one-star reviews make up roughly 25 percent of the total—pushed us even further toward the Infant Optics as the one we’d choose for a similar price. The app is pretty poorly done. You may lose a connection even with a perfect Wi-Fi signal. Some people report never being able to connect to it at all. The plug on this unit is an odd 2-piece design that is unnecessarily complicated (but it can be fairly easily replaced with another basic 5V charger if you want). All told, the M6S comes close to the functionality of the Infant Optics pick in some ways, and the ability to access the camera remotely is a huge plus, but all the other drawbacks are too much to overlook.
Baby's exposure could potentially be even lower if parents place the camera on a wall at least 15 feet from baby (a distance still good for night vision to work properly with most monitors). Given the sensitivity of baby's developing systems we recommend placing the monitor as far away from the baby as possible while still being able to utilize the night vision as intended and see baby's face to determine if they are awake or sleeping at a glance. For most of the products, this distance is between 10-15 feet from the baby.
Video quality is a metric these products should perform well in, but most of them failed to offer a true to life image even in the daytime. It is disappointing that most dedicated video products aren't doing more than providing a blurry image of the baby in the room, and fail to show the baby's features or what the human eye would see in the room. The night vision is even worse than their day vision video, with some images being so blurry and hard to decipher that parents may end up going to baby's room simply because their baby has no face.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
