      Hi,

      I have just bought this camera. It seems like the auto exposure range is limited to maintain high fps out. In low light, I have to manually increase the exposure. Some other manufacturers expose a “low light compensation” setting in UVC controls so auto exposure can increase up to 1-2fps. Can this feature be enabled on this camera?

       

      Thanks.

      Hello,

      It should be supported. I have consulted the original factory about how to open it, waiting for my news.

      Hi,

      I have ensured from the original factory and the firmware has opened the

      low light compensation function.

      Can you attach me the image you get ?
