RTSP: The Real-Time Streaming Protocol. What is RTSP and How Does It Work?

Real-Time Streaming Protocol (RTSP) remains one of the most preferred video streaming protocols for IP cameras, surveillance systems, and real-time applications — even as newer technologies like WebRTC and HLS dominate HTML5 streaming.

What is RTSP?

RTSP (Real-Time Streaming Protocol) is a network remote control for multimedia servers. It enables real-time control (play, pause, record, teardown) of live streams without downloading media files. RTSP typically works alongside RTP and RTCP, ensuring stable low-latency transmission for CCTV, conference, and surveillance feeds.

.

RTSP vs RTMP

While RTMP was once the gold standard for ingesting live video, it’s now deprecated on most browsers. RTSP continues to be ideal for first-mile delivery from IP cameras to servers, while WebRTC is preferred for real-time playback with ultra-low latency (0.5 seconds).

Compare RTSP vs RTMP
to find the right protocol for your use case.

RTSP vs WebRTC

For sub-second latency and browser-native playback, WebRTC streaming is the best alternative. It requires no plugins, works across all devices, and supports adaptive bitrate and secure transmission.

RTSP vs HLS and CMAF

HLS (HTTP Live Streaming) offers adaptive bitrate and reliability but with higher latency (5–20s). CMAF streaming, on the other hand, delivers low-latency HTTP-based delivery (around 3–5 seconds) with reduced cost and workflow complexity.

RTSP and IP Cameras

Most IP cameras natively use RTSP for live feeds. It doesn’t require an external encoder, making it perfect for real-time monitoring or video surveillance streaming
