I’ve got a basic, old-fashioned, 1980s style doorbell. Works just great for me. No Nest, no Ring, no Alexa, none of that crap. They tell you that they aren’t eavesdropping, but I don’t believe it.
Believing Google or Amazon regarding security is like believing a Democrat to keep a state secret from the press.
I don't care too much who is looking at outside of my front door, as long as they're not looking or listening inside my house.
