Network Type:
Static IP: User can set a fixed IP for network connection.
DHCP: DHCP server in LAN will automatically an assign IP configuration for the network connection
IP address: This field shows the DVR’s current IP Address. A static IP address must be set manually. If DHCP or PPPoE is selected, this value will be assigned automatically.
Subnet Mask: This field shows the subnet mask for your network so the DVR will be recognized within the network. If DHCP or PPPoE is selected, this value will be assigned automatically.
Gateway: This field shows the gateway on your network for the DVR to use when communicating with any devices not on the local network. If DHCP or PPPoE is selected, this value will be assigned automatically.
DNS Server 1: This field shows the primary DNS server for your network. If DHCP is selected and an internet connection is available, this value should be assigned automatically. This field must have a valid DNS address in order to use the DDNS feature (see Sections 4.7.5 and 7 DDNS for more detail).
DNS Server 2: This field shows the secondary DNS server for your network.
HTTP Port: Port number for HTTP/WEB communication. Additional information:
1.Set up the DVR Network Menu according to the instructions detailed in the Networking chapter of this DVR’s manual.
a.If using DHCP, all settings will be detected automatically. While DHCP is a useful tool for determining the network settings, if you set up your DVR in this manner its IP address may change at different times for different reasons, particularly after a power failure. If the IP address of the DVR changes, you may have difficulties accessing your DVR locally and/or remotely. It is strongly recommended that you assign a fixed (static) IP address to your DVR, and that in order to avoid address conflicts the IP address assigned be outside of the DHCP range of addresses your router issues to DHCP clients. Please do not set the DHCP address issued to the DVR by the router as its static IP address unless you take specific steps that program your router to prevent such address conflicts.
b.If using a Fixed IP (recommended), you will need to input the information manually. In order for DDNS to work, you must enter valid data, compatible with your network, for all four of the network setting fields: IP address, subnet mask, default gateway and the DNS Address (depending on your network hardware and configuration this may be the IP address of your router/gateway, or it may be the actual IP address of the local DNS server).
The DNS server IP is required because your DNS server provides critical information necessary for the DVR to communicate with the DDNS server.
You can obtain the actual DNS IP from your Internet Service Provider (ISP); or, from a PC located on the same LAN as the DVR, go to http://www.dnsserverlist.org/ to obtain a list of the IP addresses of their recommendation of the best servers to use for your location.
