   • Path A (official): Click “Export” to generate a .guid file. Send this file + serial + proof of ownership to Dahua support. They return a .bin reset file. Import it into ConfigTool.
   • Path B (self-help): Use a third-party tool that accepts the serial + security code → get reset code.
7. Enter reset code in ConfigTool → Clear password → Set a new strong password.
