Workflow to train and then detect people in security camera images?

I have a setup where my security camera in my front entryway takes a snapshot when it sees motion and uploads it to a dropbox folder.

I'd like to train a model on roughly 12 people, and then have it log those events. I would also like to receive some sort of notification when it sees someone who doesn't match, and ideally allow me to tag that new person.

I already have thousands of pictures I can use to train …
