Currently car theft in Thailand is one problem that affects the economy and involves transnational criminals although there are many anti-theft devices available on the market. These mechanisms include gear locking devices steering wheel locking devices clutch/brake locking systems TDS systems voice transmissions wireless door-lock remote control system and GPS car tracking devices. Of the mentioned devices the GPS tracking devices are interesting as they use the principle of connecting to the cell phone system to send on-demand the GPS location of the car to the owners phone in the case that the vehicle is stolen. However these devices are not popular in the marketplace because the service fees are quite expensive. Also the function of these devices is to send the vehicles location to the verified car owner so the protection function is activated after the vehicle is stolen and the owner is only then aware that the car has been stolen. This is different from the devices that researchers have developed. The researchers equipment for when someone tries to steal a vehicle is the system will detect the movement inside the car and send the GPS location to the car owner instantaneously. Additionally the device was developed by using LoRa technology to transmit the data giving a lower operating cost than by using a GPS tracking device as sold on the market presently.
