Owlet Dream Duo (Gen 3)

The only system here with FDA clearance: in November 2023 the Dream Sock received De Novo clearance to show an infant's pulse rate and oxygen level and to notify caregivers when readings leave preset ranges, for babies 1 to 18 months and 6 to 30 pounds. That sets it apart from movement pads and bands, though some parents find the numbers raise anxiety rather than ease it. There is no parent unit, so your phone is the monitor and Wi-Fi has to stay up. In testing, notifications were slow and the chimes quiet, more than once lagging a crying baby by over 30 seconds. Its Dream Sight camera was the first baby monitor to earn the SGS Cybersecurity Mark. List price is $380, with some features behind a yearly plan.
