Multi-Site WebRTC Surveillance: Building the Site-Edge Relay and Central SFU That Scales to 50 Sites

From RTSP at 50 sites to WebRTC on one SOC wall. The edge relay that pulls on demand and repackages H.264, the central SFU that forwards only subscribed streams, WAN tuning for long-haul links, and failover that survives a dropped site — the design behind multi-site WebRTC surveillance.

Multi-Site Video Surveillance Architecture: Why Connecting 50 Sites to One SOC Isn’t a Bandwidth Problem

Cameras at 50 sites, one control room, and feeds that stutter — so you buy a bigger pipe. That fixes the wrong thing. Here's why multi-site surveillance is an architecture problem, what always-on streaming really costs versus on-demand pull, and what the right design looks like.

PTZ Over the Web: Why Steering a Camera Is Harder Than Streaming It

Streaming a camera is one-way; steering one is a closed control loop through a human watching delayed video. This piece explains why PTZ over WebRTC is bounded by video latency — and how the data channel, ONVIF commands, control arbitration, and a dead-man's switch make it usable.

Where to Tap the Stream: Adding Live Browser Video Without Fighting the NVR

A camera has only a handful of connections, and the recorder already holds one. This technical companion walks NVR live streaming as a stream-source decision — camera main-stream, sub-stream, or NVR re-stream — plus single-pull fan-out and recording-priority reconnection.

Cloud Video Surveillance

You're Never Greenfield: What It Really Costs to Put Existing CCTV in a Browser

“Add cloud video” sounds like a fresh build, but every real deployment already has an NVR recording. This piece breaks down the real cost of cloud video surveillance on an existing estate — sunk CapEx, camera connection limits, and the egress bill nobody puts on the quote.

Why Watching 500 Cameras Is a Decode Problem, Not a Bandwidth Problem

Your network can carry 500 camera streams — but one workstation can't decode 50. This piece breaks down why the video wall is a decode problem, not a bandwidth one: dual-stream cameras, server-side mosaics, and full resolution only where an operator is actually looking.

Live Video in Surveillance: Why RTSP Cameras Still Can’t Talk to Web Browsers in 2026

Every IP camera speaks RTSP; no browser does. This piece walks the whole story — codecs, RTSP, the browser gap, and the RTSP-to-WebRTC bridge that finally gets live cameras into a tab — plus the H.265 transcode trap that separates a one-camera demo from a 200-camera deployment.
