Even though the jury is still out on the effects of EMF on the human body, this doesn't mean parents need to wait for more definitive proof before making thoughtful adjustments that err on the side of caution. Given that exposure compounds over time and with an increased number of devices emitting, you can help limit baby's exposure by turning off devices when they are not in use, unplugging wireless routers at night while children sleep, and keeping products as far from your baby as possible when in use. Even if you are not convinced that there is potential for harm, it certainly can't hurt to make choices that potentially increase the health of your home.
Long Range: Monitors that don’t connect to WiFi have a limited range, usually around 600 to 1,000 feet. While this is large enough for all but the biggest houses, we asked our testers to find out how far they could wander away — and how many walls they could put between them and the baby unit — before they went out of range, as well as to report back on what happened when they did. Sometimes there was an alarm or a notification, but other times the screen simply froze.
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.
Microphone sensitivity: There’s a difference between hearing your baby cry, and hearing every little noise. All baby monitors have the option to turn down the volume, but some offer thresholds for parents who are more comfortable with only hearing the biggest upsets, and prefer not to hear the self-comforting noises their baby makes as they fall asleep.
The best baby monitor apps allow you to monitor baby using only your existing devices, like phones, tablets or even computers. One device acts a transmitter in baby’s room, and you use another device to monitor baby. Some apps only have audio functionality, but others have both audio and video. As a plus, the best baby monitor apps often have cool features that traditional baby monitors don’t have, like remote capabilities. However, some users complain that they can be somewhat unreliable.
Movement monitoring devices do not claim to prevent SIDS, but they could potentially provide peace of mind for a better night's sleep for parents. To reduce the likelihood of SIDS, you should practice safe sleep guidelines for EVERY sleep (with or without a movement device). Always put your baby on their back to sleep, they should have their own firm sleep space with a tightly fitted sheet. Read our article on How to Protect your Infant from SIDS and other Causes of Sleep-related Deaths for more information about best sleep practices and setting up a healthy sleep environment for your baby.
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.
