The project aims to develop an advanced vehicle security system that enhances protection against theft by integrating GSM technology. This enables real-time two-way communication between the car's security system and the user's mobile device. The system provides intrusion alerts and allows remote control of the car's security features, including monitoring the vehicle's location via GSM positioning. A single main control unit coordinates various interfaces implemented within the project. The team led by the primary contributor focuses on efficient memory allocation for signal reception and transmission to ensure broader range coverage using the GSM network. Team members also contributed through coding and setup, with guidance from an assistant professor. Emphasis was placed on utilizing cost-effective components while adhering to a well-structured plan to achieve project success.
