The staff and working vehicles with frequent access to ports can enter or leave restricted areas through special channels, separating them from inbound and outbound passengers and vehicles completely for less conflicts between staff (including inspectors) and passengers, making staff concentrated on the inspection of inbound and outbound passengers and vehicles and the monitoring of channels, setting operating procedures more definitely and specifying the supervision responsibilities clearly.

Based on the independently developed face detection and identification technology and vehicle information detection algorithm, the system can identify the information of both people and vehicles in restricted areas automatically and realize intelligent control over the people and vehicles with access to restricted areas through functions including inspection control, access history recording for staff and working vehicles, expiration judgment, inbound-outbound balance judgment, abnormality alarm, etc. It includes a subsystem for people and a subsystem for vehicles. It can further standardize the inbound and outbound procedures of ports and prevent the people and vehicles from going the wrong way back the restricted areas, making customs clearance more orderly and improving the service of ports.
