The Infant Optics’s range within our test houses was never an issue, and, as with others we tested, we had to walk outside and down the street before losing the signal. The image quality was good enough to make out facial details 6 feet away in a completely dark room (as it was on others we tested). It’s easy to add more cameras to the set (you can use up to four Infant Optics add-on cameras, which are separate purchases, usually for about $100). You can mount the camera on a wall easily, pan and tilt 270 and 120 degrees respectively, and you can set the parent unit to scan between multiple cameras to keep an eye or ear on everybody at once—another nice feature that’s not unique to this model.
Features are important, but we encourage you to consider which features you think you will realistically use and which sound like fun in theory, but probably won't happen in practice. Many of the monitors carry a higher price tag and justify the price with the addition of features parents are unlikely to use in real life. Features like alarm clocks for feeding schedules, and alerts for low humidity might feel like something you should consider, but in practice, sound activation and quality images are more useful. In fact, more features often translate to being more difficult to use, and many of the features are novelty functions that most parents stop using over time. A good example of this is the Philips Avent SCD630 with an ease of use score of 8, but a features score of only 4. Try not to fall for the propaganda of bells and whistles that you might only use for the first few weeks. In the end, what you want is a good monitor with great sound and video quality.
The best monitor for sound in our tests is the Philips Avent SCD630, with a score of 8 of 10. This monitor has the best sound activation and background cancellation features in the group, and while the sound is bright, it is also clear without an echo. Most of the competition earned 4s and 5s for sound, with all of the Wi-Fi monitors only earning 4s. It seems that no matter how good your parent device might be, the Wi-Fi cameras struggle for the most part to transmit clear sound with good sound features.
One minor but potentially annoying flaw: The “on” lights on the parent unit are a touch bright, and you may be more sensitive to them since you’re likely to have the unit within view as you sleep. They appear as greenish yellow light from the face of the unit, and a charging light, which is blue when it’s fully charged. Depending on how sensitive you are to light, you may want to lay the display face down on a nightstand or cover the status lights with tape.
Traditional video baby monitors don't offer the same high-resolution picture quality we're used to seeing on our smartphones and tablets. If you want high-resolution video of your baby, you'll have to go with a Wi-Fi monitor like the NestCam that streams video to your phone or tablet. The Phillips AVENT SCD630 video monitor may not be high-res, but it's the best of the bunch.
