What is the technical term for direct connection ?

[Externet]

Hi.

I have NO router, no WiFi at home.  My 'smart' phone does have that feature which is not enabled now, I never use or need it...    Once I enabled such and printed a document from my phone direct to my WiFi printer.   What is the correct term for that connection ?  Words like peer-to-peer ; ad-hoc ?  something else ?

Stores sell a WiFi door-bell camera with intercom that can use a 'smart' phone to see who is at the door and even dialog with.   What should I look for in the specifications/instructions terminology wording to know if its WiFi connection is direct door-bell-to-phone or needs a router at home ?

The smartphone can be configured to create hotspots, which can be found by other devices. I am using it all day long.
