Prepare reCamera Node-RED Flows

Guide for creating and deploying Node-RED flows to reCamera devices.

Overview

reCamera supports two deployment modes:

• Node-RED mode: Visual programming with pre-built nodes for camera, YOLO detection, etc.
• C++ mode: Native applications with deb packages (see prepare-deb-package skill)

The deployer automatically handles mode switching:

• Stops and disables C++ services when deploying Node-RED
• Restores Node-RED services that may have been disabled by C++ deployment
