Stats I’m seeing put it north of a quarter of households with video doorbells, and rising. Not literally everyone, but a whole lot. I’d say more than half the houses in my middle-class suburban non-tech-hub-city neighborhood have one, and this isn’t some early-adopter gadget nerd crowd.
You might be incapable of recognizing hyperbole. I am saying that home security cameras are popular. They are, and videos from them are regularly shared in local news stories and on social media.
(for the record, we don’t have one)
