With the help of state-of-the-art computer technology, users can now easily monitor their car around the clock. You can also give full security of the car. This has been made possible by the vehicle tracking system. As a result, even if the car is stolen now, it is possible to identify its location. One such modern technology is Entrack. This is done with the help of GPS or Global Positioning System ( GPS), GSM or Global System for Mobile Communications ( GMS - Global System for Mobile Communication) and GIS or Geographic Information System ( GIS - Geographic Information System) . GPRS technology is associated with GSM technology . The three core technologies work independently in different environments, and the Vehicle Tracking System integrates these three technologies through state-of-the-art software to provide a clear display to the device's client. Entrac is placed in a secret place inside the car. Inside it is a mobile phone SIM card along with other components. If the car is stolen, if the user sends an SMS from the mobile phone to the SIM card number of the mobile phone kept in his car, the start of the moving car will be stopped and the car door will be closed automatically. If the law enforcement (e.g. detective police) informs the automatic vehicle tracking monitoring unit, they can use GPS and GIS technology to see the condition of the vehicle on the computer screen and retrieve the vehicle in a short time. If you have a computer or PDA at hand, enter the password specified for the vehicle and enter the entry. With the help of Google Earth, you can also see on the map of the entry itself the thief is running away by stealing the vehicle.
