Does this mean the PTZ2 is NOT compatible with a tricaster 860 running AE3? I just purchased a PTZ2 and my tricaster cannot see the video. I get an "to access this NDI stream, please update the receiver software to a version prepared using the NDI 4 SDK" message. I tried updating the NDI drivers for the tricaster, but it says they are up to date.The PTZ1 was using some components that were no longer available, the camera needed to be refreshed. The PTZ2 comes with the lens hood, but otherwise you will find that the features and capabilities of these two cameras are the same.
The PTZ2 does use NDI-HX2 and doesn't require the NDI-HX driver like the PTZ1 does. This can allow for the for NDI features like groups or discovery server support in future firmware (which is not possible with HX1), however these features are not currently in the shipping camera firmware.
Your software application does have to be running NDI version 4 libraries for the PTZ2 to be compatible (NDI 4 is the minimum version to support HX2).
