This document describes an ARM-based vehicle theft control, positioning, and collision detection system. The system uses GPS and GSM modules connected to an ARM controller to provide theft prevention, accident detection, and live vehicle tracking. For theft prevention, a fingerprint module is used for authentication. In the event of an accident, an accelerometer sensor detects impacts and alerts emergency contacts if the accident is severe by sending SMS messages with the vehicle's GPS coordinates. If the vehicle is stolen, its live location can be tracked using the GPS module. The system aims to provide security against theft, notify emergency services faster in the event of an accident, and allow retrieval of a stolen vehicle.
