Web Capture Camera
A tool that turns any web page into a virtual ONVIF camera by capturing screenshots using Puppeteer, streaming live as an H.264 RTSP feed using FFmpeg that network video recorders can discover and record.
- Node.js
- TypeScript
- Docker
Web Capture Camera exposes any web page as a virtual ONVIF camera so a network video recorder can treat a dashboard, status board, or live page as if it were a physical security camera. It captures screenshots of a configurable URL with headless Chromium, encodes them into an H.264 RTSP stream with FFmpeg, and advertises the feed over ONVIF SOAP. Built as a standalone Node.js application that I currently use to capture Weather Forecast Dashboard and serve to my UniFi Protect NVR.
Plug into existing NVR gear
The piece that makes it practical is WS-Discovery: the camera announces itself on the network the same way a real device would, so an NVR finds and adds it automatically with no manual configuration. It runs on Node.js with Puppeteer driving the browser and ffmpeg handling the encode, and the whole thing ships as a Docker image.
