I had a right faff on finding a IP security cam that didn't use the bloody awful onVIF protocol and would connect to a network without a mobile app to configure it. I take care of remote access myself, so I don't need the "feature" of having my video streams routed through a server in china so I can view it on the go.
I had the same issue with RGB lighting controllers for my shelving and bookcase, in the end I had to settle on a ESP8266 based controller and figure out the protocol with wireshark, I now have some of my lighting operable from a webpage on my home server.
I really wish there were a decent, privacy respecting hub that could be used for controlling all of this kind of gear.
