I'd like to pass on a lost password tip I that took me hours to find online and I haven't seen mentioned on ipcameratalk. I forgot the admin password, or it got corrupted. The reset procedure where you scan the QR would not work either, it errored. I also tried the email password reset in ConfigTool, no luck that way either.
After Googling and reading pages and pages of the above procedures, I found a page that explained how to do a hard reset. Hold down the reset button for 30 seconds! You may not need to hold it that long. After about 15-20 seconds, it said "Performing Hard Reset" or something like that. At that point, it was "Out Of The Box" reset and I could assign a new password without it asking for the old password. Hopefully this helps someone sometime....
Here's the web site - An Aussie company called Cornick. Looks like they private label Dahua products.
