How the FBI might have gotten inaccessible camera footage from house (npr.org)

Basically Google has a LI console.

This incident will, hopefully, encourage people to use cctv that store footage exclusively locally (on a microSD card, built-in storage, or a local NVR/hard drive you control) and avoid any cloud connectivity or optional cloud features.

Local alternative to Google Nest : Reolink, Amcrest POE, Eufy with Home Base, TP-Link Tapo, Frigate + POE cams.
