I'm also having the problem that my Dahua camera (IPC-T54Pro-AS) isn't being detected.

I have a Dahua camera that isn't being recognized, so the analytics features aren't available. I can't flash it back to the original firmware because I haven't been able to find it. 

Can anyone help me?

Please let me know if any further information is needed.
Please excuse my English; it's not my native language.

Best regards, Thomas

This is the camera that is not being recognized.
