Gateway: Displays the gateway on your network for the DVR to use when communicating
with any devices not on the local network. If DHCP is selected, this value will be assigned
automatically.
DNS Server 1: Displays 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 6.6.3 DDNS).
DNS Server 2: This field shows the secondary DNS server for your network.
HTTP Port: Port number for HTTP/WEB communication.
Bandwidth Limit (Kbps): Specify, disabled / 128 K/ 256 K / 512 K / 768K/ 1M / 3M bps. This is
the maximum bandwidth that the DVR is allowed to use on the network. This is a useful
function when connecting the DVR to busy or heavily loaded networks, or when accessing the
DVR(s) over a WAN.
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 IP 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.
