Dahua ConfigTool using Instruction

change your computer's IP address to 192.168.1.xxx then can be done.
tried this too, changed multiple times but still getting same error, "Network error, Maybe Timout". even connected the camera directly to PC, nothing in between still same error.
 
I use IE. I have had good result s with my daytime settings, but night is complicated. Depends on available light, focus, it's fun... still working on it.
