It uses 2.4GHz FHSS technology that offers a private connection between the monitor in your baby's room and the dedicated viewer in your hand. The FHSS connection should minimize interference, and most reviewers say the audio is clear. In BabyGearLab's testing, the reviewer found that the Phillips AVENT had the best audio signal of any of the monitors it tested.
A WiFi monitor gets rid of the parent unit entirely and replaces it with a smartphone app. That app connects to the baby unit over the internet, rather than standard radio frequencies. As a result, you’ll never have to worry about being out of range from your camera. If you’re at dinner and want to check in on the babysitter, you’re still connected. Since it operates from an app, it’s also easier to flip through features than trying to figure out a finicky, low-quality touchscreen, or a dozen different buttons.
The best-selling video baby monitor on Amazon is the highly-rated Infant Optics DXR-8 Video Baby Monitor — this impressive product boasts more than 10,000 5-star reviews! Though it’s a little higher in price than other products, the Infant Optics camera’s interchangeable lens system, remote adjust feature, and reliability make it a top pick for parents.
The video on its handheld unit is sharp and consistent, and even with 30 feet between the camera and the handheld unit, there wasn’t lag or interruption in the video. In addition, you can use the handheld unit to remotely point the camera at different parts of the room. Although you can't record video or take pictures with the DXR-8, these aren’t important features for a baby monitor. Setup is incredibly easy. After charging the handheld unit overnight, we plugged in the camera and it instantly connected. There was a slight lag in the video when the camera and handheld unit were 50 feet apart, which is why it only scored 90 percent in our connection test, but that’s still better than other baby monitors we reviewed. In our battery life test, the monitor lasted 10 hours – only one other model has a battery that lasts this long. This video baby monitor doesn't have Wi-Fi, but that's not a problem. Our top Wi-Fi monitor, the Philips Avent, is more expensive and didn't perform as well as the DXR-8 in our tests. This baby camera has swappable lenses for telephoto and wide-angle views. It also has invisible infrared LEDs that let you see your baby in complete darkness without waking them. The DXR-8 doesn't have a nightlight or lullabies to comfort your baby, but those exclusions don't make this baby monitor any less impressive. The warranty on the DXR-8 only lasts a year, compared to the two-year warranty on the Philips Avent.
