A major benefit for fleet managers who have GPS vehicle tracking devices installed on their company fleet of vehicles is that security is greatly improved. The company is able to know where the vehicle is at any given moment, thanks to GPS tracking. This offers significant assistance in recovering vehicles that have been stolen. This not only benefits company fleets, but private citizens who own expensive cars.
In most cases, the tracking device is placed on the car in a covert manner—meaning it is placed out of sight. If someone should take the car, that thief will not know that the device has been hidden on the vehicle. The hope is that thieves will be less likely to steal cars because they will fear they are being tracked.
If a vehicle is stolen, the hidden GPS device sends a signal to the police on a frequency that only they can receive. Some of the more sophisticated systems can detect when a vehicle is being driven unauthorized. There are some systems that will notify the owner of the vehicle via a text message to let them know their car is being used without authorization.
