3Web Basic Operations
The system supports device access and management through web at personal computer (PC).
The web client system provides functions such as information viewing, storage management, system
configuration, and playback monitoring.
The following contents are only for your reference. Different models have different functions. See the
corresponding model.
Connecting the Network
Before logging in web, connect your PC and the Device to the same network, and make sure the
network between them is normal.
Connect the device to the network.
Set IP address, subnet mask and gateway IP for PC and the device respectively.
If there is no router in the network, assign IP address of the same network segment for
PC and the Device.
If there is router in the network, set the corresponding gateway IP and subnet mask for
PC and the Device respectively.
The Ethernet ports of the Device have different default IP.
Single-control device: Network interface card (NIC) 1 to NIC n corresponds to default IP
192.168.1.108 to 192.168.n.108.
Dual-control device: Different slots have different default IP.
Slot 1: NIC 1 to NIC n corresponds to default IP 192.168.1.108 to 192.168.n.108.
Slot 2: NIC 1 to NIC n corresponds to default IP 192.168.1.109 to 192.168.n.109.
The ports are for standard NIC, extension NIC, and web management card. You need to
confirm the default IP according to the actual device condition.
On PC, execute the command of Ping device IP address to check whether the network is
connected.
Initializing the Device
When you log in the device for the first time, you need to set the login password of the administrator
account (admin by default).
Open the browser and enter the IP address in the address bar.
The default IP address of single-control device is 192.168.1.108.

Table 3-3 NIC editing parameters
Parameter Description
Ethernet
Card Displays the current NIC name.

15
Parameter Description
Network
Mode
Displays the network mode of the Device.
Single NIC: The NIC is used alone. You can select one NIC to provide HTTP or RTSP
service. You need to set one default NIC (default is Network Card1) to request
the network service started by Email and File Transfer Protocol (FTP). Once the
card is offline, the system triggers a disconnection alarm.
Fault-tolerance: In this mode, the Device communicates with external devices
through NIC bonding. You can focus on one host IP address. At the same time,
you need to set one main card. Usually there is only one running card (main
card). The system will enable the alternate card when the main card
malfunctions. The system will not be offline only if all cards are offline. Notice
that all cards need to be in the same LAN.
Load balance: In this mode, the Device communicates with external devices
through NIC bonding. Workload is balanced among all cards. Their network
loads are generally the same. The system will not be offline only if all cards are
offline. Notice that all cards need to be in the same LAN.
Link aggregation: The system uses NIC bonding to realize communication
function. All bonded NICs are working together and bearing the network load.
The s
ystem allocates the corresponding ports to the specified switches
according to the port load setting. Once one port link malfunctions, the system
stops sending out data from current port. The system can calculate the new load
and specify the new port(s) to send out data. The system calculates again to
specify the port(s) once the malfunction port becomes available.
The Device only supports LACP link aggregation.
The Link Aggregation network mode is available when the switch supports link
aggregation and is configured with link aggregation.
NIC
When the Network Mode is set as Single NIC, you can bond the current NIC to any
other one.
Management NIC does not support this function.
IP Version You can select IPv4 or IPv6 Format. Currently both IP addresses are supported.
MAC
Address Displays the MAC address of the Device.
IP Address
