I don’t use cameras connected to anyone’s cloud infrastructure inside my home. Outside is a different story - I have Nest cameras covering each entry-way into my house. Inside - there’s no real need for cameras, and if there were I’d use my own monitoring software and my own storage.
I set up a VPN server on my network and store streaming functions locally. I’m using it to monitor my 3D printer, but can do that with cameras I set up as well.
