Note: These ports are for local use only. HTTPS and 443 are requirements for OWS functionality. More information will be found in our OWS Network Requirements.
How to Change HTTP and HTTPS Ports
If you are unable to use ports 80 and 443 for networking on the recorder, you can change both the HTTP and HTTPS ports from the Setup menu.
Enter the Setup menu and navigate to the Network Configuration option. There you should see a section labeled Edit Ports. You can then change the HTTP and HTTPS port's value to what is best suited to your network.
