Supply, implementation and maintenance of a patent control system through automatic license plate recognition. The system consists of 15 PTZ cameras with CPU and license plate processing software that alternate in different locations throughout the department. Each camera has the capacity to survey at least two lanes of traffic in real time. The system can detect license plates in the field and apply the control rules at that moment, perform a massive transmission of license plates and apply the rules in a centralized way, either on-line or in batch. Integration with the IM's audit management and reporting system is included. 24/7 maintenance and equipment rotation are included in the scope.
