I am using the SIYi 8 min cam on my drone. With the Herelink controller.  
The gimbal is controlled via UART telemetry 2  
SIYi Ethernet port to Herelink Air unit Ethernet port for Video streaming

I tried using the original Qground station that was  
factory installed on the Herelink transmitter but the video stream is very slow and lagging  
So I downloaded another Qgroundstation into SD card Insert it the SD card in the Herelink controller, and installed it.  
Now I am getting a good video stream, not slow or  
Lagging

I can control camera movement from buttons, wheel, and screen  
But I can’t zoom or trigger the cam to start recording or take photos  
The version of Qgroundstation on my Herelink that I am currently using is -v5
