There's only 2 options for Dahua cameras and I tried them both. I'll try the other brands and see if I get get one of them to workI don't have that particular camera but I have a few verifocal lens cameras and it took a little playing around to get things to work how I wanted but you should be able to get the zoom to work by playing with the camera manufacure and model settings in the video and PTZ tab
Not following you on this oneDid you try the ONVIF settings?
Perfect!! Worked like a charm!One of mine I had to change the Video settings to the following to get the Zoom to work, the other I was able to leave as RTSPView attachment 28849
