Options - Users
    

In this section you will see a list of the current users defined on the
system. You can also add or delete users from here. It is recommended you do
not delete the admin user unless you have created another fully privileged
user to take over the same role. Each user is defined with a name and
password (which is hidden) as well as an enabled setting which you can use
to temporarily enable or disable users, for example a guest user for limited
time access. As well as that there is a language setting that allows you to
define user specific languages. Setting a language here that is different
than the system language will mean that when that user logs in they will
have the web interface presented in their own language rather than the
system default, if it is available.

This screen allows you to configure various permissions on a per user basis.
The permissions as of today are defined as follows:

Streams - None: the user has no access to view live streams from the
defined monitors - View: the user has access to only view live streams from
the defined monitors - Edit: the user has access to edit live streams from
the defined monitors

Events - These permissions relate to the ability to view events from the
defined monitors. The permission levels are the same as the Streams
permissions, except that they apply to recorded events

Control - These permissions relate to the ability to control
Pan/Tilt/Zoom (PTZ) of the defined monitors. The permission levels are the
same as the Streams permissions, except that they apply to PTZ

Monitors - specifies whether a user can see the current monitor settings
and change them. The permissions levels are the same as the Streams
permissions, except that they apply to monitor settings

Groups - specifies whether a user can see monitor groups and change
them. The permissions levels are the same as the Streams permissions, except
that they apply to groups

System - Determines whether a user can view or modify the system
settings as a whole, such as options and users or controlling the running of
the system as a whole. The permissions levels are the same as the Streams
permissions, except that they apply to groups.

Note
 if you are using zmNinja, users are required to have ‘View’ access to
system because multi-server information is only available as part of 
this permission

Bandwidth - Specifies the maximum bandwidth that this user can configure
(Low, Medium or High)

API enabled - Specifies if the ZoneMinder API is enabled for this user
(needs to be on, if you are using a mobile app such as zmNinja)

Finally, you can specify a list of monitors this user is allowed to access
using the ‘Restriced Monitors’ list. You can select multiple monitors by
shift+click(or command+click) on multiple monitors. If a user with
‘Monitors’ edit privileges is limited to specific monitors here they
will not be able to add or delete monitors but only change the details of
those they have access to. If a user has ‘System’ privileges then the
‘Monitors Ids’ setting is ignored and has no effect.

Here is an example of a restricted user, for example:
    

This user “home” is enabled, can view live streams and events, but only
from “DoorBell” and “DeckCamera”. This user also cannot control PTZ.
