Preface

This manual describes how to use your NVR locally or on the Web interface.
In this manual, the terms IP camera and IPC refer to the same thing: network camera, which requires

a connection to the network. And the IP device mentioned in this manual refers to an IP camera (also
known as network camera) or a Digital Video Server (DVS).

Part I Local Operations

An NVR supports two types of operations: local operations and web-based remote operations. With
local operations you connect a monitor and a mouse to the NVR and use the mouse to operate. If
your NVR has buttons on the front panel or is delivered with a remote control, you may also control
your NVR by pressing the front panel buttons or using the remote control.

The NVR has an embedded web server and allows web-based operations. To do this, you need a
client PC that has a network connection to the NVR and is installed with a web browser. You just
need to navigate to the NVR's IP address and log in to the Web interface like you log in to the system
locally.

This section describes local operations.

NIC can be chosen as the default route, and data will be forwarded through this NIC when the
NVR connects to the extranet.



Load balance mode: The two NICs are bound to the same IP address and work together to share
network traffic.



Net fault-tolerance mode: The two NICs are bound to the same IP address. In cases where one
NIC fails, the other takes over service seamlessly from the faulty one to ensure network
connectivity.

3. Click Apply to save the settings.

NOTE!



For an NVR with multiple NICs, you can configure the NICs and choose a default route. If you switch
the working mode, the enabled 802.1x and ARP protection will be disabled automatically.

 If your NVR has a PoE port or a switching port, you can configure an internal NIC IPv4 address.

3. Click Apply to save the settings.

60

DDNS

If your NVR is connected to the Internet through PPPoE, the IP address of the network changes every
time it connects to the ISP server without your awareness. This is inconvenient when you remotely
access your NVR with an IP address. To avoid this issue, you can register with an DDNS server to
obtain a domain name for your NVR and then access your NVR by visiting the domain name instead
of an IP address (http://DDNS server address/NVR's domain name) using a web browser.

1. Click Menu > System > Network > DDNS.

2. Enable DDNS, select a DDNS type, and then complete other settings.



reserved for other purposes. Make sure each port number configured is unique.

3. Click Apply to save the settings.

Port Mapping

Two port mapping methods are available:



Universal Plug and Play (UPnP)



Internal and external mapping

UPnP

UPnP enables the NVR to discover other devices on the network and establish network services such
as data sharing and communication.

To use UPnP in your NVR, you must enable UPnP in the router to which your NVR is connected. With
UPnP enabled for Network Address Translation (NAT), the ports on the NVR can be mapped
automatically to the router, and computers can access your NVR from outside the LAN.

1. Click Menu > System > Network > Port Mapping.

2. UPnP is enabled by default. Select the desired mapping type from the drop-down list. To map
ports manually, select Manual and then set external ports for the router.

NOTE!



Auto mode is recommended. Ports will conflict if not configured properly.



For an NVR with multiple NICs, port mapping should be configured based on the NIC specified as the

default route.

3. Click Refresh and check that Active is displayed for these ports in the UPnP Status column.

4. Click Apply to save the settings.

62

Internal and External Port Mapping

If your router does not support UPnP, then you need to configure internal and external ports
manually.

NOTE!



The principle of port mapping is that the internal and external ports of the NVR are consistent with
that of the router.

 Some routers may require the same internal and external ports for the NVR and the router.

1. Click Menu > System > Network > Port Mapping.

2. Select Manual from the drop-down menu in the UPnP mapping, and then set external ports

manually.

3. Click Apply to save the settings.

NOTE!

You may verify by entering the following information in the address bar of your web browser::
router's WAN port IP address:external HTTP port. For example, if 10.2.2.10 is the IP address and 82
is the HTTP port, then you enter http://10.2.2.10:82. If port mapping is effective, the login page of
the NVR will be displayed.

63

Email

The NVR can be set to send an email notification to specified email addresses when an alarm occurs.
The email contains basic alarm information such as alarm type, alarm time, camera ID, and camera
name, etc.

Before using this function, make sure the NVR has a functional connection to an SMTP server with
which you have a valid email account. Depending on the intended recipients, a connection to the
Internet may be required.

1. Click Menu > System > Network > Email.

2. Configure the related parameters.

If server authentication is required, you need to enter the correct username and password.

Enabling RAID

You need to enable RAID first.

1. Click Menu > Storage > Array.

2. Select the check box to enable RAID. A confirmation message appears. Click Yes.

Creating an Array

It is recommended to configure a hot spare disk to ensure reliable system operation and successful
rebuilding in case an array fails.

1. Click Menu > Storage > Array > Physical Disk.

2. To create an array automatically, click One-click Create.

NOTE!



There is no need to select disks when creating an array with One-click Create. The system identifies
all usable disks. RAID 1 is created when two disks are available. When three or more disks are
available, RAID 5 is created. If more than four disks are available, a global hot spare disk will be
created.

 Arrays created in this way are named ARRAYX, for example, ARRAY1, ARRAY2.

66

3. To create an array manually, select the desired disks and then click Create. In the window
displayed, enter the array name, select the array type, and select local disks. Click OK to
complete the setup. Note that no hot spare disk will be created automatically.

Rebuilding an Array

By checking array status you can determine whether maintenance is necessary. An array is in one of
four statuses: normal, degraded, damaged, rebuild. The status is normal if no physical disk is lost.
When the number of physical disks lost reaches the specified value, the array is considered damaged.
The status between normal and damaged is degraded. A degraded array can be recovered to normal
status if you rebuild it.

NOTE!

Take RAID 5 that consists of 4 disks as an example. The array is degraded when one disk is lost. And
when two disks are lost, the array is damaged.

After an array becomes degraded, it can be rebuilt automatically within ten minutes if a hot spare
disk is available, and if the capacity of the hot spare disk is not less than that of any disk in the array.
A degraded array without a hot spare disk can only be rebuilt manually under Menu > Storage >
Array > Array. By default the first local disk that satisfies requirements is selected.

Deleting an Array

CAUTION!
