Nah I’m good. It is typical that you use the CIA playbook. Immediately cast doubt and make counter accusations. I guess I shouldn’t expect good faith.
You asserted that Chinese people are taught about this without any proof.
That which is asserted without proof can be dismissed without proof. In other words, put up or sit down.
Also immediately implying that what people know that is not the official Chinese party line is misinfo seems to be straight from the Trump playbook.
And finally you refer to “a chinese friend” as an authority, you pulled a hattrick of fallacious conversation in that post.
A lot of the more modern NVR systems can be accessed from the internet. So you can use these.
Synology has security station on their NAS systems (although there is some licensing nowadays depending on model and number of cameras.
Ubiquity also offers local storage for their system, that also offers a bellcam (like ring) and different in and outdoor camera models.
Good luck!
