RTSP vs HLS vs WebRTC

Use this page when you are choosing how to get a camera stream into a browser or onto a website and you need a practical explanation, not protocol marketing.

RTSP.RUN starts from the reality that many cameras already expose RTSP. This guide explains where RTSP fits, why browsers usually need a translation layer, and when HLS or WebRTC may be a better fit depending on latency, compatibility, and rollout complexity.

What this comparison helps you decide

  • whether your main problem is browser compatibility, low latency, or rollout simplicity
  • whether you can work with a publicly reachable RTSP stream or need another ingest model
  • whether a lightweight browser player is enough or you need a more custom streaming stack

The key questions behind RTSP, HLS, and WebRTC

Start with the browser limitation, then compare latency, compatibility, and rollout fit.

This is usually caused by an incorrect address, an unreachable camera, or a blocked connection.

  • Make sure the camera is powered on and RTSP is enabled in its settings.
  • For access from the internet, the stream must be publicly accessible (private IPs like 192.168.x.x will not work externally).
  • If the camera is behind a router, set up port forwarding (typically port 554).
  • Check that the connection is not blocked by a firewall or your internet provider.

You need to configure port forwarding on your router (typically port 554) to the internal IP address of the camera.

  • Instructions for your specific router can be found online.
  • Use strong passwords and disable unnecessary services on your camera.

Yes. If your IP address changes occasionally, use a free Dynamic DNS service (for example No-IP, DuckDNS, Dynu).

  • You will get a hostname that automatically updates to your current IP address.
  • Most routers and cameras support DDNS directly in their settings.

You can check your public IP address on whatismyipaddress.com or in your router’s administration panel.

Note: With mobile or shared connections, your IP address might be shared with other users.
