It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Require authentication on cameras and media servers.
How do I check if port 8202 is open?
On Linux run "ss -ltnup 'sport = :8202'", on macOS "lsof -nP -i :8202", and on Windows "netstat -ano | findstr :8202" to see the local process. From another machine, "nmap -p 8202 <host>" shows whether it is reachable.
