Battery: We wanted a monitor battery that could last overnight, or at least eight hours, without being plugged in. We thought the ideal product would automatically cut off an idle display screen to conserve battery, work at least a few hours unplugged with the screen on, and recharge fairly efficiently. We made a rechargeable battery a requirement. We preferred units designed to connect to power via a standard USB connector, and looked for reports that the baby monitors could reliably charge, recharge, and hold a charge long-term—a disappointingly rare ability in baby monitors.
Baby monitors, despite the name, are meant more for the caregiver than they are for the baby. We asked parents about which features they felt were helpful, like a long range so they could wander carefree all over the house, and reliability so they weren’t struggling to maintain a signal. Other features like being able to play lullabies, or receive temperature alerts are only as useful as you make them. And a few features, like motion monitors, can be exceptionally comforting for some, and distressing for others.
The Samsung SEW-3043W BrightView HD's primary advantages over our pick are a larger, crisper display and a sleeker-looking package overall. But it is not our pick because its main disadvantage—a slow and unresponsive touchscreen—is such an annoying flaw that we're sure you'd prefer our pick's reliable tactile controls. The Samsung also falls short of our pick on battery life and because of other long-term battery and charging issues. On many other measures, the two monitors came out more or less even.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
