The monitor is the weird part. Maybe sky bell or ring app running on an android/iphone tablet mounted to/in the door and hard wired to power?
I'm sure he is speaking of the "Ring" doorbell that has been advertised on TV.

There are tons of options on Amazon and eBay for items that match your description, like this one. They aren't name branded or look to be high quality, but they otherwise fit your description.
Sounds like he watches too much tv, I would advise him if he's worried about a home invasion that standing in front of the door is not how to stay safe.
Using off non-standard brands that might work can also become a repair nightmare later on. There arent too many options to mount the screen that will not require a flex or armored cable or a multi conductor wired hinge and core drilling the door, most people wont want to see that in a home. An aiphone sounds like your best bet.

We use Comelit and have good success with them, it's more of a video intercom than a door bell, but they work well.
