“For example, say you live in an apartment building. Someone rings the doorbell, “it’s UPS.” Is it really UPS? If you could see them on a camera on the phone while they’re talking to you, you’d be able to see that. But how much effort is it going to take to rewire an existing apartment building with this sort of tech? Is it worth the cost? What if your door lock was smart enough to automatically let the cleaning lady in during the hours they’re supposed to be there, but prevent them coming in during the weekend when they might be there to steal something. Again, applications are there, but no one is really buying because maybe the perceived increase in convenience is not worth the cost of installation.”
You mean like these?

I don’t know “rings” sales but have heard they are selling well.
