RTSP
What is Port 554?
Port 554 is the default port for the Real Time Streaming Protocol (RTSP), a network control protocol designed for entertainment and communication systems to control streaming media servers. Defined in RFC 7826, RTSP functions as a remote control for multimedia streams, allowing clients to issue commands like PLAY, PAUSE, RECORD, and TEARDOWN. RTSP itself doesn't deliver the media data — it manages the streaming session while the actual audio/video data is delivered via RTP (Real-time Transport Protocol). RTSP is widely used in IP security cameras, video surveillance systems, and streaming media applications. Most IP cameras from manufacturers like Hikvision, Dahua, Axis, and others expose an RTSP stream for live video access.
Common Uses
- IP security camera live video streaming
- Video surveillance system integration
- Media server streaming control
- Video conferencing setup and management
Technical Details
Copy-paste commands to check port 554 (RTSP) from your terminal
Test connectivity
nc -zv example.com 554
curl -v --max-time 5 http://example.com:554/
telnet example.com 554
nmap -p 554 -sU -sV example.com
(echo > /dev/tcp/example.com/554) 2>/dev/null && echo "open" || echo "closed"
Open port in firewall
sudo ufw allow 554/tcp
sudo iptables -A INPUT -p tcp --dport 554 -j ACCEPT
sudo firewall-cmd --permanent --add-port=554/tcp && sudo firewall-cmd --reload
Security Considerations
RTSP streams from IP cameras are a major security concern. Many cameras have default credentials and expose port 554 to the internet, allowing unauthorized video access. Shodan indexes thousands of open RTSP streams. Always change default camera passwords, restrict RTSP access to VPN or local networks, and use RTSPS (RTSP over TLS) when available. Segment IoT devices on a separate VLAN.
