Most smart baby monitors are effectively just home security cameras—devices that let you watch another location with color video, night vision, and sound, so you can tell if anything is amiss. Because baby monitors are for keeping an eye on your little one rather than on your home and property, they prioritize different features than security cameras. 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 controls (which lets you swivel the camera from afar) aren't quite as common but are very welcome if you have a toddler and want to scan an entire room. The ability to record in HD 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 1080p cameras in any case.
