Dahua and Hikvision have great cameras but of course you shouldn’t trust them. Block them at the firewall. I bought mine a few years ago and preferred Hikvision for its better built in webserver for initial configuration.
On the hosting side you run Frigate, Zoneminder or BlueIris (Windows) to control the cameras and record their streams.








Dahua must have improved their software. I was trying every brand of camera about 8 years ago when I setup my system. The first Dahua I bought required their ActiveX component for Internet Explorer to see the camera output from their web interface!
I agree that Dahua looked better but at the time their web interface was so bad I kept the Hikvisions.
