OMG I figured it out LOL
I remembered that I created a .bat file many years ago to change a dahua cam parameter. So I went back to that.
If I add --globoff to the curl command, it works!
Thanks for getting me this far!
I have been meaning to create this all winter and I am running out of time before mow season comes and I really don't want my cameras talking to me while I am out there LOL.
