Maybe there were dual booting Windows and then a Windows update broke the boot partition

I found the Lorex brand of products that stores footage locally. Internet connection is not required either, as it is either hardwired or paired directly with the NVR wirelessly.

Just out of curiosity, which distro did you end up using?

You could probably stretch it to 10-12 hours if you turn all the hardware kill switches to off, which activates “lockdown mode.” It turns off every sensor on the device.

I daily drive a Librem 5. First thing to note is do not expect a well polished experience. Battery life is bad, only about 4 hours of light use, and 8 or so hours if left in suspend. It can do VoLTE, send SMS, use web apps and any apps coded with libadwaita or kirigami. Other desktop apps can be forced to scale on the display, but it won’t be perfect.

I use Signal desktop as my main means of communication on the Librem 5. I have a spare normie phone for setup, but Waydroid is an option. I do use Waydroid for a few apps that have no web browser equivalent.

Idk, all I can say is, you have to really want it to live with it. I don’t do gaming or heavy social media use or anything removed that, so it is just fine for me. But it’s definitely not for everyone.
