SIYI mini A8

Hi everyone I am having trouble setting up the SIYI mini 8 camera

I tried using factory QGCS installed on herelink transmitter
I’m getting video stream, I can control camera movements. Recording is working,but I can’t take photos. The video stream is very slow on the app.

I downloaded another version QGCS -V5
Video stream, gimbal control is working perfectly, video is not lagging
But I can’t trigger camera , I can’t start record

The camera is connect to herelink via ethernet
Gimbal control is connect to UART/telem 2
