DETEXI Basic Configuration 5 - 31
What is DETEXI NVR Domain Controller?
If you security installation has two or more DETEXI NVRs
in different locations or a single site with hundreds of
cameras, you should explore upgrading with the DETEXI
NVR Domain Controller module in order to organize the
NVR domain consisting of the main NVR — Domain
Controller and several child NVRs. This will allow you to
get advantage of centralized user access control and
camera management.
The central administration point of the distributed
network or domain of DETEXI NVRs is the DETEXI NVR
Domain Controller software. Any DETEXI NVR that holds
the NVR Domain Controller license could become the NVR
Domain Controller. The NVR Domain Controller connects
to any child NVR if they are connected to the Internet or
the same LAN and the passwords are known and ensures
that all communication with the recorders is authenticated,
and that the user has the specified rights to access
particular NVR resources.
Video is Recorded on the Child NVRs
Each particular NVR from the domain (child NVR) is
responsible for recording video from its own set of
cameras configured in the NVR Cameras List.
Centralized User Access Control and Camera
Management
The NVR Domain Controller maintains a single Users List
with security information for all domain users and
authenticates all Remote DETEXI Clients’ access.
The NVR Domain Controller allows users to administer and
control all cameras in the domain from a single Domain
Controller interface considering all child NVRs as one
powerful NVR. Without this, managing larger numbers of
NVRs would be cumbersome.
y The NVR Domain Controller and child NVRs in
the domain must be connected to the Internet or
the same LAN.
y Domain Controller usually doesn’t have its own
cameras (though it is not forbidden) but provides
centralized user provisioning and management.
y When an employee (administrator or operator)
leaves, deleting their account does not change
any other accounts, or the profile to which the
account was assigned. Having this type of
control prevents unauthorized access to NVRs.
