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.
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.
It really depends on what you feel most comfortable with. There are audio monitors that allow you to listen to any noise coming from the nursery, vital monitors that track sleep and breathing and video monitors that add sight to sound. Babylist parents overwhelmingly choose video monitors. The security of seeing what your child is up to—like if they’ve gotten tangled in their swaddle, pulled their diaper off or climbed out of the crib—can be worth the extra cost of a video monitor.
