1. The document describes a vehicle security system that uses IoT technology to prevent vehicle theft. It uses sensors to detect vibrations if someone tries to steal the vehicle. It then sends a signal to a microcontroller and sends an SMS alert to the owner. 2. The owner can then log into an IoT-based web server to track the vehicle's location using GPS and control the vehicle remotely by activating features like honking or stopping the engine. 3. The system aims to provide affordable vehicle security and alerts the owner via SMS if the vehicle is being stolen whether they are near or far from the vehicle using technologies like sensors, microcontrollers, GPS and GSM communication.
