Im testing this lib for implementation and plugged in a brand new amcrest camera to my network and I am getting the following error running the probe command from the terminal.

Hi @cfsbhawkins ,

Could you please provide the output with --logo-level all added to the command line. It looks like the response from the camera may not be following the standard. If I can see the response, then I can adjust the code.
