This document summarizes a dealership inventory management and vehicle security system. It consists of three main components: 1) A proprietary module plugged into each vehicle's ODB-II port that reports location and usage data with low battery drain. 2) A wireless gateway at the dealership that communicates with the modules and reports vehicle data to the cloud backend. 3) Cloud backend that allows accessing and sorting vehicle data from any web browser or mobile app. The system allows dealerships to easily track vehicle locations, monitor access and test drives, and reconcile inventory without physically checking each vehicle.
