I've been looking into getting it working manually with iSpy for PTZ tracking.. but I'm trying to figure out the syntax for actually sending commands.
So far I've figured out that the command URL is : /ipnc/
with the following commands
1 = Up
2 = Down
3 = Left
4 = Right
5 = Left Up
6 = Right Up
7 = Left Down
8 = Right Down
