#1Protocol Comparison Overview

RTSP (RFC 2326/7826) is the universal standard for CCTV camera feeds and local NVR recorders, whereas WebRTC (RFC 8829) enables native sub-second video playback in modern web browsers without plugins.

#2NAT Traversal & TURN/STUN Relays

While RTSP requires open router ports (e.g. 554), WebRTC utilizes STUN/TURN servers to establish encrypted peer connections across restrictive firewalls and enterprise NAT environments.

#3Latency Benchmark Table

- WebRTC: ~50ms – 200ms glass-to-glass latency (Ideal for interactive PTZ control & browser monitoring) - RTSP (TCP/UDP): ~100ms – 400ms latency (Ideal for NVRs, VLC, and AI pipelines) - LL-HLS: ~1.5s – 3s latency (Ideal for CDN distribution to 100,000+ viewers) - Standard HLS: ~6s – 15s latency (Standard video-on-demand)

Frequently Asked Questions

Can web browsers play RTSP streams natively?

No, modern browsers do not support RTSP natively. You need a streaming gateway like RTSPLink to convert RTSP into WebRTC or HLS for native HTML5 video playback.
