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.
