follow-you camera
Amazon's new rotating, follow-you camera is useful -- and invasive
Echo devices are mostly known as Alexa smart speakers, but in 2017, Amazon started adding screens with cameras in them to a line called the Echo Show. Now these kinds of countertop computers -- also known as smart displays -- have become their own aisle at the electronics store. Options include Google's Nest Hub Max, which uses facial recognition to identify which family member is in front of it, and Facebook's Portal, which offers its own more limited ability to track faces during calls.
