How can i use the ZILINK Model CH43H in NetCam Studio

I have a ZILINK Model CH43H. But the ZILINK is not a Brand in Netcam Studio. I have tryed other Models. The FOSCAM FI9820W works with the PTZ. But ich can not use the Zoom in/out funktion.
I have also tried ONVIF. But Zoom in/out also not works here.
Can someone help me?
Thanks!

Seems like a nice camera. I cannot find that specific model, but if it’s optical zoom ONVIF is the only way to get it connected. If that doesn’t work, then dorry.
