DDNS — reach your camera from anywhere

Most home and office internet connections use a dynamic public IP that changes over time. A Dynamic DNS (DDNS) hostname always points at your current IP, so you can watch your camera without memorising or updating an address.

How it works

1. Your router or camera registers a hostname such as myhome.ddns.net.
2. A small client keeps that hostname pointed at your changing public IP.
3. You use the hostname in your RTSP URL instead of a raw IP.

Using a DDNS hostname with RTSP.cam

Replace the IP in your RTSP link with your DDNS hostname, for example:

• rtsp://user:pass@myhome.ddns.net:554/Streaming/Channels/101

Make sure the RTSP port (usually 554) is forwarded on your router to the camera, and that your ISP gives you a public (not CGNAT) address. Private IPs like 192.168.x.x are only reachable inside your local network.

Popular DDNS providers

• No-IP, DuckDNS, Dynu — free tiers suitable for a single camera.
• Your router vendor’s built-in DDNS (ASUS, Keenetic, MikroTik, etc.).
