node-red-contrib-onvif-ng 0.9.0

Modernized ONVIF nodes for Node-RED 4.x

npm install node-red-contrib-onvif-ng

node-red-contrib-onvif-ng

Modernized ONVIF nodes for Node-RED 4.x using the agsh/onvif library (ONVIF 4.7 compatible).

This project is a maintained continuation of
node-red-contrib-onvif-nodes by Bart Butenaers, updated for modern Node-RED runtimes and real-world camera behavior.

Legacy branch

The bart-original branch preserves the original upstream implementation by Bart Butenaers. It is retained for historical reference and is not merged into main.

✨ Key Features

• ✅ Node-RED 4.x compatible
• ✅ ONVIF 4.7 tested
• ✅ Centralized profile cache (no repeated device queries)
• ✅ Reliable media stream handling
• ✅ Explicit capability discovery nodes
• ✅ Clear status reporting
• ❌ PTZ intentionally excluded (for now)

📦 Included Nodes

Configuration

• onvif-config
  Handles device connection, authentication, profile caching, and connection health.

Media

• onvif-media-stream

  • Get Stream URI
  • Get Snapshot URI
  • Reconnect

  Uses cached profiles only — no live negotiation at runtime.

• onvif-media-profile

  • Get profiles
  • Create / delete profiles
    (Profile tokens come from the device profile cache.)

Discovery / Capability Inspection

These nodes are discovery tools, not continuous event streams.

• onvif-events
  Discovers supported ONVIF Events and topics via GetEventProperties.

• onvif-recording
  Discovers recording capabilities and configuration.

ℹ️ These nodes intentionally return similar payloads for each invocation. Their purpose is capability inspection, not live subscriptions.

🚫 PTZ Status

PTZ support is not included in this release.

Reason:

• Not used in production by the maintainers
• High UI and device-specific complexity
• Better handled as a future optional module

PTZ work done so far has been intentionally carved out and may return in a later release or as a community contribution.

🔐 Profile Cache Contract (Important)

• Profiles are fetched once during device initialization
• Cached centrally in onvif-config
• All nodes consume profiles from the cache
• No node performs live profile discovery during runtime

This ensures:

• Predictable behavior
• Faster execution
• No UI deployment deadlocks

📡 Supported Cameras

Tested with:

• Hanwha / Wisenet cameras
• Other ONVIF-compliant devices (results may vary)

ONVIF implementations vary widely — this project favors robust behavior over strict spec assumptions.
