Another big plus? Its "basic but secure" radio frequency (RF) connection, Wirecutter says. Unlike monitors that transmit via Wi-Fi (and can be hacked from virtually anywhere on Earth), the DXR-8 is pretty hack-proof. It uses a 2.4 GHz FHSS (Frequency Hopping Spread Spectrum) signal. Long story short, a hacker would pretty much have to be in the apartment next door, using just the right listening equipment to eavesdrop on your baby, tech journalist Carl Franzen explains at Lifehacker. He goes on a personal quest to find a hack-proof baby monitor before the birth of his first child – and settles on the DXR-8.
Another prominent Wi-Fi–enabled monitor is the Withings Home video monitor, which we dismissed without testing. This is The Nightlight’s pick for the best video monitor. The most notable drawback to the Withings is that currently more than a third of Amazon reviewers give it two or fewer stars (out of five), citing problems similar to what you see on most other Wi-Fi video monitors: bad connectivity, a bad picture, unreliable air-quality sensors, and issues with overall quality and durability. In reply to some of the negative reviews, Nokia stated that it was looking into making improvements to this model. The rebranded version, the Nokia Home Video & Air Quality Monitor, was recently released and has not yet received many reviews (the app has mixed reviews).
With a 1,000-foot range and DECT technology, the VTech Safe & Sound Digital Audio relays sound with excellent clarity. Two-way communication offers a way to calm a baby when he or she is waking up or trying to fall asleep. It also includes a night light for late-night feedings. The digital display indicates signal strength and power/battery life. This monitor offers a full range of alarms when your baby wakes — audio, indicator lights, and vibration.
So, we split our remaining finalists into three groups: WiFi Monitors for those who want to have an unlimited range or the ability to check in on their baby from anywhere, Movement Monitors for those who are comforted by hearing their baby’s vital signs, and a “standard” category for parents who want a quality monitor, but aren’t looking for that extra level of support.
We don’t think most people would be happiest with a Wi-Fi–enabled baby monitor. The benefits—primarily, being able to view the camera footage remotely, on multiple phones, without keeping track of a separate monitor—do not make up for the disadvantages Wi-Fi monitors have as a category. Security is probably the first thing on most people’s minds. The likelihood of someone hacking into your baby monitor is remote, but it’s possible, said Mark Stanislav, director of application security at Duo Security, in an interview with The Wirecutter. You’re relying on the security of your own home network and also the ability of the manufacturer to secure all its devices. “Once you get into an Internet-connected device, and it really depends on what kind of device it is, but these devices very often bypass your home’s router and firewall. Basically, once you’re connected to this device, you are inside the home’s network. So, it’s possible to use these devices to access other devices in a home,” Stanislav said. (Stanislav was also involved in Rapid7’s research into the vulnerabilities of Wi-Fi–enabled monitors.)
So we recommend choosing a baby monitor that uses a different frequency band from your cordless phone and other wireless products in your home. The band that your cordless phone operates on should be printed somewhere on it. Remember that interference can vary widely depending on where you live, the electronic devices you have at home, and the ones your neighbors have. If, for example, you have a 2.4 GHz wireless product, such as an older cordless phone, choose a baby monitor that doesn't operate on the 2.4 GHz frequency band. People with newer phones that use DECT will have fewer issues with interference.
While digital monitors minimize the possibility of unwittingly broadcasting images and sounds to other devices, any wireless device (analog or digital) can interfere with other wireless devices, such as your baby monitor, cordless phone, wireless speakers, or home wireless router. To solve the problem, first, try changing the channel on your baby monitor or on your router. If you still have interference and you can't return the monitor, try keeping other devices as far away from your baby monitor as possible.
Some audio/video monitors filter out "normal" sounds and motions. The receiver is supposed to turn on only when your baby makes an unusual motion or sound, such as crying or rolling over when he's waking up from a nap. This feature is designed to extend battery life, although the receiver should be docked for overnight monitoring to keep the battery charged. We haven't tested any models with this feature, so we don't know how well it works.
The HelloBaby might be a standard monitor, but it excels at the basics. It scored better than some of the more expensive WiFi monitors in picture clarity, and was hands-down the easiest to use. Just open the box, plug in the two devices, and you’re ready to go. No difficult packaging to tear through, and no account setup or device pairing necessary. Our testers had it up in running in less than 3 minutes each time.
