To improve car security, this study presents an SMS-controlled car security system by incorporating image capturing and voice recording techniques. The device is operated by a mobile phone and is connected to a PIC, GPS, and GSM modem. The entire system is made up of two sections: the transmitting and receiving sections. The transmitting part is made up of the microcontroller, which serves as the system's brain, the global positioning system (GPS), which is used to obtain precise location and time, a GSM modem (Siemens TC35) that sends and receives messages and voice call, extremely small snapshot camera which takes the pictures of the car thieves, process it into Jpeg file and forward it to the PIC through a serial port, and voice recording device which receives the conversation of the car thief and also forward it to the receiving part for storage.
The nRF2401 receiver and the memory card that serves as a storage device for data files make up the receiving ends. This device can carry out commands sent to it via text and SMS from a mobile phone. The modem is queried by the microcontroller to see whether there are any messages from the users through the hidden condense microphone, the user can make a voice call and listen to the thieves conversation. This advanced vehicle security system is ideal for tracking stolen vehicles and their intruders.
