6. ACKNOWLEDGEMENT
It gives us a great sense of pleasure to present the report of BE project undertaken during BE
Final year. We owe special debt of gratitude to Mrs.SANYUKTA CHETIA, Assistant
professor, Department of Electronics& Telecommunication Engineering of Jorhat Institue of
Science & Technology, for her constant support and guidance throughout the project and
preparation of the project report. It is for her cognizant efforts that our endeavors have seen the
light of the day.
We would also like to take the opportunity to acknowledge the contribution of Mr.
SATYAJIT DAS, Head of Department of Electronics &Telecommunication Engineering, Jorhat
Institute of Science & Technology for his full support and assistance during the development of
the project.
We would also like to thank our Institution and all the faculty members without whom this
Project would have been a distant reality. We also extend our heartiest gratitude to all our
friends and well wishers.
Last, but not the least, we would like to thank the Almighty for giving us courage and
enlightening us throughout this time.

7. ABSTRACT
With the advancement of many vehicle manufacturing companies and owning a vehicle
specially the four-wheelers is now, just more of an opinion. In making consumer friendly cars,
security often takes the back seat and the car lifters exploit this drawback of manufacture. Only
the luxury cars are well equipped with the latest security measures as the security options at
their disposal are using GPS (Global Positioning System), which are costly and require monthly
fee too. So, the consumer friendly cars end up owning very basic ammunition to protect from
any sort of intrusion. This limitation of the present day can be overcome by this project of ours,
which is very cost-effective as it uses GSM (Global System for Mobile Communication).
