Ok, nice people at Krontech!
now that I managed to establish the WLAN-connection to my 2.1, I was for the first time trying out the http-based GUI for the camera. I am so overwhelmed how nice and smooth all works and now that I grasp the possibilities by completely controlling the camera not only with this GUI but also with JavaScript, I really have so say this publicly:
THANK YOU! I did not really know, which incredible camera and work I got for my money, and which part I missed until now. Thank you, honestly!
Now I got to dig into the API! Woooohooo!
