This is a very helpful anecdote, thanks!

Yes! Read a book out loud, preferably to your kids, recording each chapter as a file. Then use m4b-tool to combine all the chapter files into a full audiobook.

They have updated it so that you don’t need to use your phone number as the identifier you share with other people so that they can message you. You can now give out a username and your new contact will not be able to learn your phone number.

As for Signal itself knowing what your phone number is, I don’t see that as much of a problem, because they intentionally don’t know anything useful about you. They publish redacted subpoenas and their responses so you can see just how little data they can provide. They don’t know who your contacts are so there’s no social graph to be drawn.

It’s about the exact combination of extensions you have installed, along with all of the other info that a nosy website can obtain from you (installed fonts, User Agent string including exact version numbers, etc). It doesn’t come down to any one particular piece of info, but every bit adds to the overall picture. Here is a good overview and their main page runs an active test on your browser.

Second this, including buying from Costco. I don’t love the Lorex interface, but they’ve been around for a long time and can’t really compete on the modem Ring-style features so they’re now advertising the privacy benefits of their local storage.

PoE (Power over Ethernet) cameras are the way to go, connecting the camera wires directly to the NVR box, which doesn’t itself need to be connected to your network. The NVR box has a hard drive and an HDMI port. If you do optionally connect it to the network (but just don’t), then their app will facilitate connecting to your box either locally or over the internet so that you can stream your video directly from your hard drive, not their cloud.

If you want it protected against power outages, you just put the NVR on a UPS and you’re done.

Of course, if a burglar finds your NVR and takes it, then all of your footage is gone.
