node-red-contrib-cctvql

Node-RED nodes for cctvQL — a natural-language query layer for CCTV systems.

Ask questions like "Were there any people at the front door last night?" directly inside Node-RED flows, fetch live events, and send PTZ commands — across Frigate, Hikvision, Synology, Dahua, Milestone, ONVIF, and more.

Installation

npm install node-red-contrib-cctvql

Or in Node-RED: Menu → Manage Palette → Install → search cctvql

Prerequisites

A running cctvQL server:

docker run -p 8000:8000 \
  -e CCTVQL_ADAPTER=frigate \
  -e CCTVQL_FRIGATE_HOST=http://192.168.1.100:5000 \
  ghcr.io/arunrajiah/cctvql:latest

Nodes

cctvQL Query

Ask cctvQL a natural language question. The answer arrives on msg.answer ready for a notification, template, or debug node.

Inputs: msg.query (string) — overrides the configured default query
Outputs: msg.payload (full response), msg.answer (plain text), msg.intent

cctvQL Events

Fetch recent detection events, optionally filtered by camera or label. Can poll on an interval or trigger on an incoming message.

Outputs: msg.payload — array of event objects

Send a pan/tilt/zoom command to a camera.

Inputs: msg.cameraId, msg.action, msg.speed, msg.presetId
