The superior concept offers the control of different locations via one system. Locations can be either several sites of a company, several companies within a building / building complex / business parks or several individual companies that use a common access control system. Different types of controllers/terminals, connection and reading techniques can also be managed per location. Within one building it is possible for several companies to use collective doors without seeing the data of the other companies (mandators). Tailor-made - Simple operation, clear and precise arrangement and data protection are guaranteed by a hierarchical user organization. The superuser has all rights within the system, personnel managers only manage persons within the system, location managers only have access to the location allocated to them and these rights can also be specially defined.
