2 NVR networking solutions
This the NVR has two Ethernet ports LAN1 and LAN2. Supports the private network
of the cameras, and 2nd one for WAN local remote connections. LAN2 is used for
network devices for automatic detection within the NVR software.
Option One:Private Network Setup
Camcorder network is a network exists only network cameras and NVR, there is no
other network equipment, and this network is dedicated to the NVR and network
cameras, audio and video transmission. Dedicated camera network must be connected
with the NVR LAN2, and ensure that the LAN2 camera network functions are enabled
(factory default enabled detailed configuration, see "Network Video Recorder User
Manual quick configuration through LAN1 access NVR.
10M/100M/1000Mbps RJ45 Internet port
For connecting the Internet or local network, And NVR need to search the camera by
manually.
The camera dedicated network topology shown in Figure 2-1

Option II:Open network.
The open network refers to the network in addition to the network cameras and NVR,
there can be other network devices, network topology can be free to organize, just need
to ensure communication between the NVR and network camera is smooth. In the use
of the network, LAN2 needs to turn off the camera dedicated network.
Open network, the need to manually search for and add network cameras, see detailed
operation quickly configure.
Open network topology shown in Figure 2-2.

function

Before removing a hard disk from the NVR during operation, unload the disk,
otherwise. The disk may be damaged.

Please supply stable power supply, otherwise the disk may be damaged or loss of
data.

Maximum capacity of single hard drive is 4TB.

Suggest to use more than two hard drive to achieve the performance balance,
3.1 Hard disk recommended
Given the current market of different brands, the uneven quality of the different models
of hard, recommended to use Seagate or Western Digital brands which are designed for
security/server applications offering 24x7 reliable operations.
Recommended model: Western Digital’s WD AV-GP and Seagate’s SV-35 SERIES
3.2 Days of recorded
Calculate recording days:
Firstly: Use the formula 1 to calculate the recording capacity q that one channel
record need each hour
q= d ÷8×3600÷1024 (formula 1)
Secondly: calculate the recording days
w– Single capacity of single hard drive, Unit ( MByte)

4.3 Startup


Ensure that a power supply is connected to the NVR correctly.
Before starting the NVR, ensure that a monitor is connected to the HDMI or VGA
interface of the NVR correctly.
If the power indicator on the front is off, connect a power supply and turn on the power
switch on the rear panel to start the NVR. If the power indicator on the front is steady
in red, press the off/on button on the front panel to start the NVR, the NVR conducts a
self-test and then display the result on the screen。
When an abnormality is detected and the self-test screen stays on, choose to continue or
shut down in the lower right corner of the screen. If you choose to continue, the NVR
enters the login interface.

The hard disk(s) required by the NVR must be provided by users. Hard disk detection is
performed during startup. If the detection fails, check whether it is caused by the following
causes:

The hard disks are new and unformatted. In this case, format the hard disks.

The hard disks are formatted, but the file system is inconsistent with the one supported
by the NVR.

The hard disks are damaged.
- 12 -
4.4 Shutdown
Do not cut off the power supply when the system prompts "Shutting down".
When the NVR is operating, avoid cutting off the power by turning off the power
switch on the rear panel or removing the power cord.
The NVR may not operate normally when a power supply exception occurs, likely
causing damage to the NVR in serious conditions. In such a circumstance, you are
advised to use a regulated power supply.
To shut down the NVR before logging in, press and hold the PWR button on the front
panel for over 3s. The NVR is closed successfully when the power indicator on the
front panel changes from steady on to flashing in red.
To shut down the NVR after logging in to the main interface, click
in the upper
right corner or press and hold the PWR button on the front panel for over 3s. The
shutdown interface appears, as shown in Figure 4-3.
Figure 4-3 Shutdown interface
Enter a valid password and click Shutdown. When authentication is successful, the
prompt "Are you sure to shut down?" is displayed. Click Yes.
4.5 Login
Take the following steps to log in to the NVR:
Step 1
Enter your user name and password on the login interface of the NVR.
- 13 -
Figure 4-4 Login interface of the NVR
The super user is admin and the password is also admin, both of which are case-sensitive.
Change the password after logging in to the NVR for the first time. When a user enters
incorrect passwords three times within an hour during login, the account is locked. For how
to unlock the account, see section “Network Video Recorder user manual".
Step 2
Click Login to enter the main interface.

5 Quick setup
Quick setup is intended to group together some frequently used functions to facilitate
the configuration management of NVR. For the NVR, the quick setup functions cover
the network configuration, disk configuration, data and time configuration, webcam
search, and video configuration of the NVR. For the cameras added to the NVR, the
quick setup functions cover the network configuration, code stream configuration, and
motion detection configuration of the cameras. Figure 5-1 shows the Quick Setup
interface.

NVR basic information
Set the name of the NVR and change the date and time.
Synchronize the time of cameras manually or automatically.
- 15 -
If you select the manual mode, click
for time synchronization. If you select the
auto mode, the NVR synchronizes the time of cameras automatically.
Section 2: NVR network configuration
 One default IP address of the NVR is 192.168.0.121, another IP address default
is192.168.1.121 when network interface 2 is used.
 Parameters such as the IP address, subnet mask, default gateway, and DNS address
can be set in basic network configuration. The network connection status and speed
are displayed in real time.
 Network interface 2 of the NVR supports the camera-dedicated network function
(enabled by default).

A camera-dedicated network is a network where only webcams and the NVR exist.
After the camera-dedicated network function is enabled, the NVR does the following:

Enables the DHCP service and assigns IP addresses to webcams automatically (the
DHCP function is enabled on the webcams).

Searches for webcams in the network.

Adds the searched webcams automatically and enables 24/7-hour video recording.
Figure 5-2 shows the topology of the camera-dedicated network.

Section 3: hard disk management
Formatting will clear all video data on hard disks.
Before removing a hard disk from the NVR during operation, unload the disk;
otherwise, the disk may be damaged.
Manage the hard disks of the NVR as follows:





To format a hard disk, click Format. In the confirmation dialog box, click Yes. It
takes about 10 minutes to format a 2 TB hard disk.
Load or unload hard disks. Before removing a hard disk from the NVR, unload the
hard disk.
Modify a hard disk group.
Check the statuses of hard disks (normal, abnormal, unformatted, and unavailable).
Check the available space and total space of hard disks.
Section 4: camera quantity alarm
The NVR searches for webcams in the network automatically when the
camera-dedicated network function is enabled.


When the number of webcams does not exceed the management capability of the
NVR, the NVR adds the webcams automatically.
When the number of webcams exceeds the management capability of the NVR, the
NVR adds random webcams based on its management capability automatically.
The remaining webcams cannot be added and an alarm is generated, as shown in
Figure 5-3.
