Nowadays, a lot of cars have been stolen in the world. Once the vehicle is being stolen, owner cannot track their vehicle. They do not know where to find the vehicle and the opportunity to get their vehicle back is very low. It makes so hard to track the vehicle when there is no evidence. Hereby, this project aims to develop Anti-Theft Vehicle Security using GPS, GSM that will be more useful for all owner vehicle and more reliable. This system will track and monitor the vehicle’s location. For this time being, vehicle tracking system has been nominated as one of the best tracking systems for the losses of vehicle. Generally, GPS tracking uses a system of satellites orbiting earth to find the actual location. The main objective for this project is to develop a device to control and prevent vehicle from stolen. Even the vehicle they stole, it can be tracked by using Global Positioning System (GPS) for navigating through a large building are clear. ATVS can be divided into two parts which are hardware and software development. The hardware development includes the GSM modem and GPS receiver. This project will use a GSM as anti-theft application which is to disable and enable the vehicle engine using system if the vehicle gets stolen integrated with Google Maps. The GSM modem, GPS receiver will work as locator system. This project being use Agile Model Methodology to provide software development systems within the specified time frame and the allocated budget. It is an iterative and incremental approach that focuses on the involvement of the user. In conclusion, it will increase the chances of recovering the car intact. In addition to tracking cars in real time and anywhere, the proposed solution aims at providing antitheft features such as live tracking, tracing and proximity alerts as well as additional information about the vehicle.
