From a pure imaging standpoint, night vision is vital for watching your baby sleep from another room, and is standard for most baby monitors. Motorized pan and tilt (which lets you swivel the camera from afar) isn't quite as common, but is very welcome if you have a toddler and want to scan an entire room. High-definition is a nice plus, but you don't need the highest-resolution sensor to keep tabs on your baby—most of the monitors we test use 720p cameras rather than 1080p.
Compared with other Wi-Fi–enabled video monitors, the Arlo has advantages. As a product from a reputable manufacturer of home-security cameras—another Arlo model is an also-great pick in our guide to the best outdoor security cameras—the Arlo’s hardware and app support have a larger owner base and a longer track record than similar platforms supporting more recently launched baby monitors. You can see the difference in comparing the tens of thousands of satisfied reviews on Arlo’s app to the weak handful of reviews you typically see about Wi-Fi–enabled competitors. Those Arlo app reviews, which span over two dozen updates dating back to 2016, suggest a history of successful app support and satisfied customers. We often see promising new Wi-Fi monitors emerge, and we consider all of them fairly, but until they withstand the test of time like Arlo has, it’s hard to justify recommending any of them over the more proven option.
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.
