Testing battery life for all the monitors was for the parent device only. While some of the dedicated options have a battery in the camera in the event of a power outage, most do not, and they are not intended for use as an all-night option. So while we would support a cordless camera for monitoring baby, due to safety concerns with babies and strangulation hazards, none of the products in our review offer this.
By default, Arlo Baby records in 720p resolution, though you can switch to 1080p if you prefer. You can also adjust the field of view and fine-tune notifications on what triggers an alert. You do have to position the camera manually, however, and the gap between getting a notification on our phone and actually being able to jump to live video was a little laggy for our tastes.
Sound devices relay what is happening in baby's room via sound only. A great sound option is quiet unless the baby is making noise so that you won't be disturbed by white noise or constant static. This basic monitoring type can be all you need if your goal is being alerted when your baby is crying and needs your assistance. This style can be elementary with sound only like the V-Tech DM111 or it can have bells and whistles like a nightlight, 2-way talk, lullabies, and mic sensitivity adjustment features like the Philips Avent DECT SCD570/10. Most parents can get by with a sound only device as it provides the information you need to determine if your baby needs you or not.
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.
One of the primary uses of baby monitors is to allow attendants to hear when an infant wakes, while out of immediate hearing distance of the infant. Although commonly used, there is no evidence that these monitors prevent SIDS, and many doctors believe they provide a false sense of security. Infants and young children can often be heard over a baby monitor in crib talk, in which they talk to themselves. This is a normal part of practising their language skills.
There are a few things you can demand from a decent HD video baby monitor, like a crystal clear image and good night vision capabilities. And there are things you can expect of a good Wi-Fi-enabled monitor, like easy remote access from a smart device with real-time streaming audio and video. Then there are things you might hope for from a baby monitor, like two-way talk and solid battery life.
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.
Range: Range is the main drawback of an RF model, as audio monitors can roam farther out, and a Wi-Fi connection can theoretically be checked anywhere. We wanted an adequate range in a typical home—to be able to maintain a signal up or down a flight of stairs, across the house, and out on a patio or driveway, but we didn’t expect much beyond that. We zeroed in on monitors rated to about 700 feet of range1 or greater.
A big screen, a camera that zooms and a built-in nightlight make the In View monitor a great pick when you’re on a budget. The monitor also offers all the standard features: low-battery and out-of-range indicators, sound-activated lights and rechargeable batteries for the handheld monitor. Use the camera as a tabletop or mounted on the wall. And if you plan on having a big family, the monitor works with up to four cameras.
