When logging in, a Viewer’s Dashboard will only display events they have been allowed to access. This permission is set using Custom Filters. Simply, you assign one or more of your Custom Filters to a Viewer’s user account. Then, when they log in, they can only see the events which have also been assigned that Filter.
To assign a Filter to a Viewer’s account, in Manage Users, click the Filter Slider icon on the Viewer’s row:
This will open the Custom Filters box, containing all the Custom Filters you have created:
Check any Filters you wish to be assigned to the Viewer and Save.
Now, when the Viewer logs in, their Dashboard will only display events which have been assigned the Filters you selected.
