Re: Ignorance is bliss
"Of course. Why would one install a simple circuit consisting of three pieces of wire, a buzzer, a power source and a button when one can use a computer that has to be networked to a massive bank of servers halfway around the world and requires a cell phone to properly use?"
Because not everyone lives like you do. We care for an elderly relative and have a combination of ring / alexa devices, key safes and cameras that allow us to monitor the house and people coming and going.
We have had an instance when we were out, a visitor (innocent it ended out) that matched the description of someone that had invaded the house of someone else on our road called. We were able to answer the ring and record the incident. How could your "normal" doorbell help us in what we need to do?
There are more things in the world than you know and experience.
