4.1 Getting Started

This chapter introduces device initial settings such as boot up, device initialization, reset password, and quick settings.

4.1.1 Boot up

For device security, connect the NVR to the power adapter first and then connect the device
to the power socket.
The rated input voltage matches the device power button. Make sure the power wire
connection is OK. Then click the power button.
Always use the stable current, if necessary UPS is a best alternative measure. Step 1 Connect the device to the monitor and then connect a mouse. Step 2 Connect power cable. Step 3 Click the power button at the front or rear panel and then boot up the device. After
device booted up, the system is in multiple-channel display mode by default.

4.1.2 Device Initialization

4 Local Basic Operation

Parameter
Description
Net Mode
Multi-address: Two Ethernet ports work separately through either
of which you can request the Device to provide the services such as HTTP and RTSP. You need to configure a default Ethernet port (usually the Ethernet port 1 by default) to request the services from the device end such as DHCP, Email and FTP. If one of the two Ethernet ports is disconnected as detected by networking testing, the system network status is regarded as offline.
Fault Tolerance: Two Ethernet ports share one IP address.
Normally only one Ethernet port is working and when this port fails, the other port will start working automatically to ensure the network connection.
When testing the network status, the network is regarded as offline
only when both of the two Ethernet ports are disconnected. The two Ethernet ports are used under the same LAN.
Load Balance: Two network cards share one IP address and they
are working at the same time to share the network load averagely. If one of them fails, the other can continue working normally.
When testing the network status, the network is regarded as offline
only when both of the two Ethernet ports are disconnected. The two Ethernet ports are used under the same LAN.
The Device with single Ethernet port does not support this function.
Default Ethernet Port
In the Ethernet Card list, select an Ethernet port as a default port. This setting is available only when the Multi-address is selected in the Net Mode list.
