Is there any trick to getting the PTZ controls working via the driver? I've got a DS-7608NI-I2 / 8P with 4 PTZ cameras and 4 domes. The streams work fine and I can control the PTZ from the Hikvision App or the web interface, but not via the C4 app. The Lua output shows the command is coming in, but there is a disconnect somewhere as the cameras don't respond. Curious if there are specific NVR settings or specific setup I need in the driver to work with a camera behind an NVR.
