## Overview

ORRA is an EdgeX Foundry retail reference-architecture project, represented here by deployment demos rather than application source code. The Kamakura demo names camera management, ONVIF/MQTT device services, EdgeX platform services, and edge video analytics with model/data support; a second demo provides a simpler EdgeX configuration. The tree and README do not establish runtime call or data-flow wiring, so the graph shows these components without inferred connections.
