Bluetooth/GMRS Car Security System with a Randomly Located Movement Detect Device

Abstract

A car security system that links the user, a starter disable unit and a randomly located device is presented. The last one actuates as a movement detector, and the user can hide it anywhere inside the vehicle, which gives a strong level of security since there is no physical attachment to the car. A prototype has been constructed, using Bluetooth between the non-fixed device and the starter disable unit; the system sends a warning message to the user if any movement is detected via general mobile radio service (GMRS). Test results and some future improvements are commented at the end of this paper
