Doorbell that is not smart (no cameras etc)?!

I don't currently use a doorbell, but I want to install a simple one- No ring doorbell or anything smart. Just a simple doorbell people push instead of knocking.

I feel a bit silly because I really can't seem to find anything that doesn't connect to WiFi, have a camera, etc. Am I just not searching the correct thing or is there no privacy-safe doorbell anymore?!?

camera cameras connect don doorbell etc find install knocking people privacy ring ring doorbell simple smart wifi
