undervolter/krushitel ? reverse-engineered prompt

Build me a Go tool for checking Dahua CCTV cameras by serial number and prefix, with a simple intuitive interface. I want it to be able to scan for possible vulnerable cameras, check serials, and show useful details about found devices. It should also support changing the OSD text on a camera, taking snapshots, and pulling available camera credentials if they can be found.

Make it work cleanly on Windows and other common platforms if possible, and include a config file so the settings are easy to edit. The app should feel practical for lab and research use, with clear output, decent error handling, and no confusing setup. If you need to look up current Go or Dahua related docs online while building it, go ahead.
