User security in AirVision is set up by administrative personnel and is similar to Microsoft Windows:
Each system user has an identity, including a username and password
A User may be a member of one or more User Groups
Access and rights are assigned to User Groups
User Groups in AirVision are usually assigned by job responsibility (e.g., Data QA, Site Technicians, System Administrators). A group can optionally have its access limited to only certain monitoring sites. Users can be members of more than one Group, and each site can have a different access group.
