What is port 554 used for?

Port 554 is the standard TCP port used for RTSP (Real Time Streaming Protocol). It is commonly used by Hikvision / Dahua IP Cameras, UniFi Protect, Frigate NVR, go2rtc, VLC. Network control protocol designed to establish and control media sessions between endpoints (IP security cameras, NVRs).

How do I check if port 554 is open?

Enter your public IP or hostname into the scanner tool and click Check. A sub-second raw TCP socket handshake will be initiated from our edge server to port 554 on your target. If the 3-way handshake finishes with SYN-ACK, the port is OPEN. If an RST packet is returned, the host is reachable but the port is CLOSED. If packets time out without response, the port is FILTERED by an ISP or firewall.

Why does port 554 show as closed or filtered?

If port 554 reports CLOSED or FILTERED, confirm that: 1) Your service is actively running and bound to 0.0.0.0 (not just localhost/127.0.0.1); 2) Your router has a port forwarding rule directing external port 554 to your machine's local IP; 3) Your operating system firewall (Windows Defender Firewall, ufw, or iptables) allows incoming connections on port 554.

Q: Is port 554 safe to expose to the public internet?

Exposing port 554 carries elevated security risks (High risk). Many IP cameras have known firmware vulnerabilities and weak default credentials. Keep camera streams behind a VPN or authenticated media proxy. For remote services, consider placing them behind a secure VPN (such as WireGuard or Tailscale) or restricting inbound access with strict IP firewall rules.

Security Advisory: RTSP (Real Time Streaming Protocol) (Port 554)

Many IP cameras have known firmware vulnerabilities and weak default credentials. Keep camera streams behind a VPN or authenticated media proxy.

Recommendation: Keep port 554 closed to WAN traffic. Connect remotely using WireGuard, Tailscale, or an SSH tunnel.

Port Forwarding & Troubleshooting Checklist

If port 554 returns CLOSED or FILTERED, work through this verified diagnostic checklist:

1 Verify RTSP is enabled in camera/NVR network settings.
2 Forward external TCP port 554 to internal camera LAN IP.
3 Test RTSP stream locally in VLC via 'rtsp://user:[email protected]:554/stream1'.
