Hi ModalAI,

I have the problem, that I see no points from the stereo cameras of our Sentinal Drone. In the Web Portal, I can only choose "Voa Pc Out" but there are no points shown. Do I need to calibrate the cameras first? How can I check if the stereo cameras are working?

Regards
Laurenz

I just found out, that the *voxl-dfs-server* is disabled at default. So I run *systemctl enable voxl-dfs-server* and it worked fin.
