  2. Modify the IP address (192.168.1.64 for example), username(admin) and password (12345) for the encoder via Device Manager;
  3. Pull RTSP Stream of Axis IP Camera (one by one) into the codec directly no matter whether it's successfully streaming in the encoder;
  4. Run a browser like Chrome and enter the following CGI command in the browser's Address field: http://192.168.1.64/cgi/download?file=log&user=admin&pwd=12345, then save the log;

  2. Modify the IP address (192.168.1.64 for example), username(admin) and password (12345) for the encoder via Device Manager if required;
  3. Focus on the problem you're experiencing and trying to figure out how to reproduce it;
  4. Run a browser like Chrome and enter the following CGI command in the browser's Address field: http://192.168.1.64/cgi/download?file=log&user=admin&pwd=12345
  5. It's very important to note that it'll be much better to run the above CGI command when the problem is being reproduced.
