Hi all, I have three Voyager II webcams and have the answers you need, I think.
Here are the commands for the PTZ :
UP----------------------->http://IP/ptz.cgi?camera=1&move=up&speed=100
Down------------------->http://IP/ptz.cgi?camera=1&move=down&speed=100
Left----------------------->http://IP/ptz.cgi?camera=1&move=left&speed=100
Right--------------------->http://IP/ptz.cgi?camera=1&move=right&speed=100
Home--------------------->http://IP/ptz.cgi?camera=1&move=home&speed=100
Note：
'Speed' range is 1~100 but I found that this is actually a range of morion, in other words, if you use 100, then it moves 90 degress in the specified direction, so I generally use about 20 to get the kind of increments I want.
I don't know the commands to go to presets.
The video looks best using Motion jpeg, in my opinion. The command to get that is:
