Don’t worry if your Wi-Fi tends to be spotty because this monitor operates on a secure radio frequency. Parents applaud its long range — up to 590 feet — and sensitivity to sound no matter where they are in the house. And if you’re in a far-off room, you’ll still know the temperature in the nursery because it’s displayed on the screen at all times.
We tested monitors daily over a period of several months, in three houses: one nearly 100 years old with plaster walls, plus a newer home with standard drywall construction, and a two-level 1960s home with a driveway on another level from the kids’ rooms. We tried the cloud-based monitors with two routers to be sure that any connection issues were with the monitors themselves and not the Internet connection.
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.
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.
Watching your child from moment to moment is far more important than going over footage from previous nights, so baby monitors don't usually make a big deal about saving video for later, whether using built-in storage or through a cloud service. They can take snapshots and short clips when they detect movement, but they won't offer time-lapse videos of entire nights at once, or let you page through hours or days of footage. Those features are useful for identifying burglars, but they don't really help you watch your child unless you're in a Paranormal Activity sequel.
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.
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.
