Car access control can represent a security problem if it does not have technological support and / or depends solely on people (lack of image support, distraction or absence of staff, etc.). For this, it is necessary to develop solutions, for example, based on automatic recognition systems for automobile license plates and on radio-frequency identification (RFID) technology that automate automobile access control. Although there are commercial plate recognition systems, these systems are highly expensive, are closed, are not extensible and do not allow the implementation of notifications (for example, so that security personnel can intervene in the presence of an unauthorized vehicle). Also, the existing solutions are not adapted to Bolivia, since they require that the license plates of the cars are clearly identifiable, which is obviously not the case in our country (blurred plates, uneven edges, arbitrary positioning, etc.).
