• the attached device has one or more detectors, connected with a central unit which, among other functions, allows to activate the sound and light alarm means and the means which block the engine of the vehicle, and which is the result of a new combination of the elements already mentioned with:
• the alerting means operate not only in small areas but also in large areas, thanks to the automatic sequence of either a coded telephone call and led by the public wireless telephone network to a small decoding / multiplication center that exists on land, or transmitting the position coordinates of the vehicle to a receiving center also placed in the ground.
• This last action by making the arrival time of the police or other entities shorter at the place where the vehicle is, also indirectly allows the security of the data recorded in the video recorder located in the tamper-resistant box which encloses the central unit of the device presented.
• This automatic operating device remains active during the day and during the night, so in the period when the drivers are more vulnerable they are also protected.
