10. Network Configuration

10.1 Configuring the WAN Port

The WAN port connects the NVR to the internet via your router.

  1. Make sure the WAN port of the NVR is properly connected to the router with an 8P8C network cable.
  2. From your NVR, in the main menu, select 🔒 (ADVANCED CONFIG) > NETWORK > WAN.

AVtech NVR3 - Configuring the WAN Port - 1

text_image ADVANCED CONFIG CONNECTION CAMERA DETECTION ALERT NETWORK DISPLAY RECORD NOTIFY WAN LAN E-MAIL DDNS NETWORK MONITOR NETWORK TYPE IP GATEWAY NETMASK PRIMARY DNS SECONDARY DNS PORT DHCP ▼ 192.168.1.112 192.168.1.254 255.255.255.0 168.95.1.1 139.175.55.244 88 EXIT
  1. If the WAN port is connected to a router (not a hub), you can choose either "DHCP" or "Static" for "NETWORK TYPE".

  2. Choose "Static" if you know the network segment of your router.
    For example, if your router's IP address is 192.168.0.1, then the network segment is 192.168.0.xx (with xx ranging from 2 to 254).
    In this case, you can assign the IP address of the NVR by yourself.
    ○ Choose "DHCP" if your router supports the DHCP function, and you do not know the network segment of your router.
    In this case, the router will automatically assign an IP address to your NVR.

  3. Configure the DNS setting and port number.
    The default port number is 80. Typically, the TCP port used by HTTP is 80. However in some cases, it is better to change this port number for added flexibility or security.

  4. Then, note down the IP address shown in "IP". This is the IP address assigned to your NVR by the router. You'll need it later for port forwarding.
  5. Click the "DDNS" tab and select "eagleeyes" in "SYSTEM NAME".
  6. Note down the whole address under "CURRENT HOST ADDRESS", such as MAC000E5318B3F0@ddns.dvrtw.com.tw. This will be the address used to access your NVR remotely.

  1. Select "EXIT" to return to the live view, and continue to the next step for port forwarding.

  2. From the web browser of your PC, enter the IP address of your router to access your router.

  3. Enter the user name and password if needed.

  4. In the router setting interface, go to the port forwarding (or virtual server) rule configuration page. The naming of port forwarding or virtual server may vary based on different router brands. To know where it is, refer to the user manual of your router.

  5. Enter the NVR IP address and the port number you just noted down and enable this rule.
