I found the post you mentioned, but unfortunately the script does not work with 1500Wg and that is why I posted this question here.
Anyway - I am currently writing a script, which at this moment is able to get a frame from the cam, but it still needs some "fine tuning"
Has anyone tried to get the EDIMAX IC-1500Wg wireless network cam to work will zone minder?
I am even not able to view camera output in my browser (linux + firefox).
