I scavenged a IP camera RC8021. I think it was Xanboo. Many of above works and I want to contribute some findings of my own. This is basicly listing, so it will be long 🙁
Hope that this is some use. I have not tried to set any of these values yet. These are basic stuff, so probably others have also discovered them.

Mine is so called "wiped out". So there is no web pages to set up the camera. All there is are the links for video and snapshot. And of course http cgi.
