It may surprise you to hear that simply being able to last through the night, unplugged, with the display off, qualifies as exceptional battery life for a baby monitor. The Infant Optics was one of the only monitors in our testing that could easily do that, and then last a while longer the next day before needing a charge. (The manufacturer claims it lasts 10 hours with the display off—we got that amount of time off of a full charge, even when checking the display intermittently.) This model also charges via a USB connection, which sets it apart from competitors, some of which use ineffective and inconvenient proprietary DC chargers or even disposable batteries.
The camera, which is the most elegant looking of the testing group, sits on a magnetic base that unfortunately cannot be mounted on the wall and must sit on a surface. The camera itself cannot be tilted or panned. It can only be adjusted manually within the concave base—meaning it can be pointed downward, at least a little bit, but its wide-angle lens lessens the needs for dramatic angle adjustments. The unit also include a “privacy mode” where the decorative cover can be rotated to block the camera and signal it to not record any audio or video.
Baby video monitors with all the latest bells and whistles cost around $200, sometimes more depending on the feature set. However, you can find solid baby monitors for $100 to $150 less than that, though you'll sacrifice on video resolution and some features. Cloud storage can add to the cost of a baby monitor in the form of an ongoing subscription, though that feature is usually optional.
Most monitor systems have an electrical cord or nonrechargeable battery option for the unit in the baby's room. And receivers typically have an electrical cord or rechargeable batteries. Some models are notorious for burning through batteries at an alarming rate. Parents have complained that even monitors sold with rechargeable batteries built in can drain quickly. Our Baby Monitor Ratings , available to subscribers, include an evaluation of battery life. Subscribers can also check out our battery report and Ratings (for subscribers).
The features we focused on were those we thought either increased the performance of the monitor or made it more user-friendly for parents and increased the odds of getting good quality sleep. We looked for monitors that have sound activation that keeps the parent unit quiet when the baby isn't crying, so parents can potentially fall asleep faster because they don't have to listen to white noise. Some of the monitors were so loud, even at low volumes, that the white noise might keep light sleeping parents awake; this defeats the purpose of having a video product to begin with. We also liked the models with screens that automatically "wake" and/or go to sleep.
