Normal door bells are pretty great and have less overhead and maintenance...

All tech puts it's best foot forward, some of it's really nifty, but a camera on every street corner is always going to pose more risks than it's worth IMO...

It's work to go back to the old ways but I think this is one we step we should really all take.

I think your take on cameras is legitimate, but from my home office I can't hear my doorbell if I have the door closed or if I have music playing at even a low volume. Installing a smart doorbell that notifies me when rung was a significant upgrade over the old doorbell.
