How to Build a Facial-Recognition Doorbell with a Raspberry Pi

I want to buy a smart doorbell, but the cost of them is a little outside of my budget. Instead, I’m using a Raspberry Pi, a speaker system, and a camera to build a smart doorbell system for a fraction of the cost.

In our last project, we created a doorbell system which rang when a person was at the door. This time we’ll expand on the code to allow the project to identify when people we know are at the door, and announce it accordingly. This will let us choose to either run to the door, or hide upstairs when our friends or inlaws drop by unexpectedly.
