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).
1
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 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.

4.1.1 Adding an IP Device
This section provides multiple options to add an IP device. Choose
one as appropriate.
Option 1
1. Click Camera > Camera > Camera. The system automatically
searches for IP devices and lists the discovered.
25
2. (Optional) To search a specified network segment, click Search
Segment and then set the address range.
3. You may choose one of the following ways to add an IP device:
⚫ Click Add All to add all the discovered IP devices allowed
(depending on channels supported by the NVR).
⚫ Click Custom Add. In the window displayed, enter the IP
address and complete other settings, and then click Add.
You may also click Search Segment and add discovered
cameras in the list.
⚫ Click
Click
to add the camera.
Option 2
1. Click
in a window.
2. Select the desired IP device and then click OK.
Option 3
Use this option to add an IP device that is connected to a different
router, for example, when the NVR and the IP device are connected
across the Internet.
NOTE!
First you need to enable port mapping at Setup > Port > Port
Mapping on the IP device's Web interface.
1. Click Camera > Camera, click Custom Add.
2. Choose an option:
26
⚫ By IP
A. On the IP device's Web interface, go to Setup > Port >
Port Mapping, find the external IP (public IP) and
external port number.
B. On the NVR: Select a protocol, enter the above-
mentioned IP address and port number. Enter the
username and password.
C. Click OK.
⚫ By MyDDNS
A. On the IP device's Web interface, go to Setup >
Network > DDNS, enable DDNS, select MyDDNS, set
a domain name and get the server address.
NOTE!
⚫ After setting the domain name, check that you can use the
device address to access the IP device's Web interface.
⚫ Make sure the MyDDNS server and the NVR are
connected (ping the MyDDNS server from the NVR).
B. On the NVR: Select a protocol, enter the above-
mentioned server address, domain name, username
and password.
C. Click OK.
27
⚫ By a domain name
A. On the IP device's Web interface, go to Setup >
Network > DDNS, enable DDNS, select DynDNS or
NO-IP, enter the domain name that you have signed up
on the DNS website, enter the username and password,
and then click Save.
B. On the NVR: Select a protocol, enter the domain name
mentioned above, enter the username and password.
The port is the external port of the IP device.
C. Click OK.
NOTE!
⚫ If Custom is selected for Protocol, the port is the mapped
external RTSP port of the IP device.
⚫ Do not add an IP device to an NVR using different
methods (e.g., IP and MyDDNS) at the same time.
⚫ When an IP device is added by MyDDNS, domain name
(NO-IP or DynDNS), or IP (public IP + public port) and it is
not connected to the same router as the NVR, alarm is
configurable, but alarm push is not available.
Option 4
Use this option only when the IP device to add supports the standard
RTSP, and all you need from the IP device are just view live and
playback. IP devices added in this way cannot be configured from the
NVR.
1. Click Camera > Camera.
2. Click Custom Add.
28
3. Click to select a camera in the list, select Custom from the
Protocol drop-down list, and then click the Protocol button in the
lower left corner.
4. In the Protocol window, name the protocol, enter the RTSP port
number, select a transmission protocol, input the resource paths,
and then click Apply.
29

instructions on GV-Eye. This function is only applicable to GV-Eye
V3.0.0 or later.
11.1.3 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.

113
11.3.3 Port Mapping
Two port mapping methods are available:
⚫ Universal Plug and Play (UPnP)
⚫ Internal and external mapping
11.3.3.1 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 on your NVR, you must enable UPnP in the connected
router. 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 Network > Advanced > 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.
114
NOTE!
⚫ Automatic mapping (Auto) 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
under UPnP Status.
4. Click Apply to save the settings.
11.3.3.2 Manual 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 Network > Advanced > Port Mapping.
2. Select Manual for Mapping Mode, and then set external ports
manually.
115
3. Click Apply to save the settings.
NOTE!
After port mapping is completed, you may access the Web
client of your NVR 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.
11.3.4 FTP
Use this function to automatically upload images to a preconfigured
FTP server.
1. Click Network > Advanced > FTP.
2. Select the check box to enable FTP.
3. Enter the IP address of the FTP server, username and password,

NOTE!
⚫ Click Test to verify whether an FTP connection can be
established.
⚫ If the remote directory is not specified, the system will
create different folders directly by IP, time and camera.
You may also specify a remote directly, for example,
FTPtest/xxx/xxx, then the system will create the directory
first and then create folders by IP, time and camera.
116
4. Select the desired camera and then click
right to Upload
Schedule. In the Upload Schedule window, select the desired
image type and set time periods.
NOTE!
⚫ If you select Event, Motion, Alarm or Video Loss, you also

selected will not be used for storage).
12.2.3 Rebuilding an Array
By checking array status, you can determine whether maintenance is
necessary.
NOTE!
To be alerted when an array is degraded or damaged, you
can configure alarm-triggered action at Alarm > Alert.
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
through rebuilding.
NOTE!
Take RAID 5 that consists of 4 disks as an example. The
array is degraded when one disk is lost. When two disks are
lost, the array is damaged.
122
A degraded array can be automatically rebuilt in ten minutes if these
conditions are met: a hot spare disk is available; 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

Problem
Possible Cause and Solution
No images are
displayed in live
view on the Web
interface.
Check if the bit rate is 0Mbps in the
live view window.
If yes, check if the firewall has been
disabled, and the anti-virus program
has been stopped on your
computer.
If not, maybe it is because the
graphics card driver on your
computer is not working properly.
Try installing the driver again.
A camera is offline,
and No Link is
displayed.
Click Maintenance > System Info >
Camera. The cause is displayed under
Status. Common causes include
disconnected network, incorrect
username or password, weak
password, insufficient bandwidth.
Check network connection and
network configurations.
If it indicates incorrect username or
password, check that the camera
password set in the NVR is the one
used to access the camera's Web
interface.
If it indicates denied access for
weak password, log in to the
camera's Web interface and set a
strong password.
If it indicates insufficient bandwidth,
delete other online IP devices in the
NVR.
159
Problem
Possible Cause and Solution
The NVR displays
live video for some
cameras and No
Resource for
others.
Set the camera to encode the sub
stream, and decrease its resolution
to D1.
Set the NVR to use the sub stream
first for live view.
A camera goes
online and offline
repeatedly.
Check if network connection is
stable.
Upgrade the firmware for the
camera and the NVR. Contact your
dealer for the latest versions.
Live view is
normal, but the
recording cannot
be found.
Check if a recording schedule has
been properly configured.
Check if the time and time zone
configured in the NVR are correct.
Check if the hard disk storing the
recording has been damaged.
Check if the desired recording has
been overwritten.
Motion detection is
not effective.
Check if motion detection is
enabled, and the motion detection
area is properly configured.
Check if detection sensitivity is
properly set.
Check if the arming schedule is
properly configured.
