We took these criteria into consideration, factored in user feedback and reviews from across the Web, and eventually narrowed the list to eight cameras for testing. We used each camera for several months, taking notes on the interface and any difficulties we ran into. We connected each model to multiple routers, and used each from various distances and through walls to test range. We also ran each monitor from a full charge down to zero to check battery life. Finally, we evaluated each monitor's night vision in dark environments. Read more about our tests in our full guide to baby monitors.
To test connectivity, we put the handheld unit and the camera in neighboring rooms with 30 feet between them. We looked for lag, choppiness, and changes in the video or sound quality. While we rated it separately, we also did tests to estimate each baby cam’s maximum indoor range. Each camera we tested has a range of 100 feet or more, which is enough for an average-size home.
The audio quality is excellent, thanks to VTech's use of DECT 6.0, so you shouldn't hear any interference, static, or echoing when you listen in on your baby. Since the monitor uses a special frequency to relay the signal from the monitor in your baby's room to the parental unit, everything is encrypted and secure. No one but you will hear your baby.
The Philips Avent DECT SCD570/10 is a sleek looking, quality sound device that has a more extended range than much of the sound competition. It has a battery life of over 30 hours and excellent sound clarity for true-to-life sounds. The nursery unit has a nightlight, lullabies, mic sensitivity function, and a 2way talk to baby feature providing the most popular features for today's demanding parents.
Using the buttons, you can swivel the DXR-8's camera (so you can eyeball more of the room) and zoom in close. It actually comes with two interchangeable lenses – a standard and a zoom lens – and you can also buy a separate Infant Optics Wide Angle Lens (Est. $12), all of which can be used with the zoom button. This gives you lots of flexibility when deciding where to mount your camera, Baby Bargains points out. "Depending on the configuration of your nursery, your only option may be to put the camera on a dresser across from the crib -- then the normal lens might do. But if you mount the camera on a wall above the crib, the zoom lens might be better." Later, if you use the monitor in a toddler's room or playroom, the wide-angle lens might be the best choice.
