After receiving our new PTZ4K camera we attempted to change the default password. The procedure appeared to go OK, but now we can not log in. Is there a procedure to reset the camera back to factory defaults? We tried the on screen factory default option, but that only seems to reset the camera settings not the name or password. Tech Support said that if that didn't work we would need to send the camera back for repair. This seems a little drastic for a simple password issue. There should be some procedure to fully rest the camera back to all defaults.
