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.
Eufy, a company known for its robot vacuum cleaners, is branching into baby monitors with the new $135 Security SpaceView monitor. The monitor comes with a handheld display featuring a 5-inch LCD screen and enough battery power to let you check in on the nursery throughout the day. We're waiting to get our hands on the Security SpaceView camera, but with 330-degree tilt and 110-degree pan, it sounds like there's little that will escape the 702p camera's view. Other features include night vision, noise alerts and two-way talk. Stand by for a full review.
As you’d expect, the talk back functionality and audio quality in general are great—easily better than the crude talk back features on our video monitor picks. With the battery lasting about 19 hours on a full charge, this monitor had the strongest battery life of any in our test (not entirely a fair comparison, as this is the only one with no screen to power). Rated to a range of 1,000 feet, it exceeds the range of our pick (700 feet) both as advertised and in practice during tests.
If you aren't interested in having a video baby monitor, the VTech DM221 is the very best audio-only monitor you can buy. You can listen in on your baby or get vibration and light-based alerts when the monitor is in silent mode. The five LED lights indicate the level of sound so you can tell whether your baby is cooing quietly or shrieking for mom and dad.
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.
