Have considered a plain old doorbel and a peep hole on the door?
Low tech, cheap, cheap to install, lasts a lifetime.
Heck, if safety is the concern, install a periscope. Yes, mirrora inside a tube, to get to see, from a distance, who is at the door.
You want footage? Photos?
Install a local camera. Like one of those that are setup by biologists to film animals in the wild. Triggered by motion sensing. Or talk with someone technically inclined and install a local system.
I’ve disconnected the doorbell at every place I’ve lived in the last 10 years. If I’m expecting you I’ll be waiting and opening the door for you, everyone else can leave a message or find a different way to contact me

We can only hope these companies are treated as collaborators in the future.
How were collaborators treated the last time around though?
Volkswagen, Ford, UBS, and IBM are all doing pretty well.
Nike, Adidas
How was Nike involved? They didn’t exist until ~ the 70s I thought.
Sorry, Hugo Boss
Ah, that one makes sense.
