# Roles and Permissions for Air Quality Sensors
This article describes the set of roles and associated permissions for Verkada [Air Quality Sensors](https://docs.verkada.com/docs/air-quality-sensors-overview.pdf). For more information on roles and permissions for other Verkada product lines, see [Roles and Permissions for Command](https://app.gitbook.com/s/NRq5qDDjsYNxwNzF1bcB/users-and-permissions/roles-and-permissions-for-command).
* **Site-level roles** determine the access a user or group has to devices in the site.
* **Org-level roles** allow users or groups to manage permissions and devices at a global level.
* **Permissions** are set using roles, which define the level of access users and groups have to devices and settings within an organization and its sites.
***
### Permissions considerations
* Subsites inherit permissions from all parent sites, including the ultimate parent.
* Users can belong to multiple groups. When roles conflict, the user receives the **highest role** granted directly or through any group.
* Group-assigned roles can be manually upgraded but not downgraded. Remove the user from the group with the higher role to downgrade their access.

A No Access user **cannot** view air quality devices within a site.
