An update on the PTZ controls for the Mini PTZ and the Hikvision DS-7104N-SN/P (China version with multi-language firmware).
Upgraded the firmware using (yes, hold your breath) the GUI. Went from version 3.0.13 150503 to 3.0.18 151231. PTZ controls are now working in the NVR GUI for the Mini PTZ cams, NVR GUI is still in english, NVR settings preserved. I've attached the 3.0.18 firmware I used in this post. I had to try the upgrade twice, first time it gave me an error. I went to another option in the menu, came back and tried again. This time it worked.
The firmware attached is good for both the DS-7104N-SN/P and the DS-7108N-SN/P I've updated both types at different sites.
ALL FLASHING IS DONE AT YOUR OWN RISK - This worked for me, that does not mean it will work for you.
NOTE: Considering that the NVR update solved the issue I can only assume the camera was correctly setup and the hacked china firmware (3.0.13) that came with the NVR had broken PTZ control protocols.
