Statistics released by the Polis Di Raja Malaysia (PDRM) revealed that 5,920 Proton cars were stolen between January and October last year. Police believe the high demand for spare parts in the black market is the main reason for the large number of local cars being stolen. Recently, as the car stolen cases rising up, news about stolen laptop from a parked car is also increasing. The proposed system will be a turning point as to reduce all the car stolen cases. This system is implemented by the usage of Global System for Mobile Communications (GSM) communication, specifically by using the Short Messaging System (SMS) to the user’s mobile phone as an alarm. The system works when there is any sensor of car alarm system is been activated, and sends notification immediately to user mobile phone by suing SMS message. In conclusion, this project was successfully implemented as far as individual part and combined projects is concerned. It is recommended that the system to be improved in future by adding a built-in G-Shock sensor that has five (5) level settings and can record multiple impact points. The SMS reply from the user to turn OFF the system should be embedded in the system.

INTRODUCTION Vehicle Security Alert System is a security system that is designed to protect and alert the user on certain happenings that need prompt attention to the car [1], [2].Vehicle Security Alert System is a vehicle safety system is required at present as the crimes involving the theft of the car or the car breaks rampant today[3]. This system involves the real connection with the conventional alarm system connected to the Programmable Interface Controllers (PIC) and GSM Modem. When the negative situations occur, the car security alarm will activate and if the car door had been opened, a signal will be send to the PIC. Later the PIC will process the data and will transmit the signal to the GSM modem. Here the GSM modem will send a notification SMS to phone the owner of the vehicle immediately [4]. The proposed system is applied for transferring of GSM communication by sending a SMS message to the user’s mobile phone. The system is used for car protection in combination with the vehicle security system. In general, the project is fully hardware configuration and categorized into two parts: electronic and telecommunication part. This project is design by using a transmitter, which transmit signals to another device
