User Configuration
Add, delete users or edit user permissions. Only admin can perform these operations.
A user group is a set of permissions in the system. When a user group is assigned to a user, this user
has all the permissions specified for the user group.
There are four user types in the system:
Admin: Default super administrator in the system, has full system access. Its initial password is
1111
.
Default: Default user reserved in the system, cannot be created or deleted, and only has access
to live view and two-way audio. If the default user is denied access, the corresponding channel
is locked when no user is logged in, and
appears in the window.
Operator: Has basic permissions and access to cameras.
Guest: Only has access to cameras by default.
