Sure it can. If a crime occurs, they can hand their footage over to the police. That's different from the police having free access to all cameras, everywhere.

> I am therefore forced to assume that anything I do at my front door is sent directly to the CCP or the CCCP or FSB. That, to me, is far less desirable than the NSA/CIA/TLA knowing what I do at my front door.

Why? Local, US-based government agencies have much more power to hurt me than the Chinese or the Russian government do.
