I have the PTZ control working great to my legacy analogue PTZ cameras via the HikVision DVR (DS-7208HUHI-K1) but there is one aspect that is frustrating me... the cameras (old Swann units) use the Iris Open as a 'Select' to get into config menu and select items.
I cant see a way to do that via PTZ controls.
Camera has auto-focus so the focus buttons do nothing, so I was wondering if it is somehow possible to reconfigure them to send Iris Open/Close instead?
