Name
server
The name server is responsible for as-
signing a unique IP address to a web ad-
dress or URL (e.g. www.google.de). Also
known as DNS (Domain Name Server).
When a domain name is entered into a
browser, the DNS searches for the cor-
responding IP address of the server and
forwards the query on.
The IP of the provider’s DNS can be en-
tered here. However, it is often sufficient
to select the IP of the gateway. This then
forwards the queries independently to the
provider DNS.
DHCP
The DHCP server automatically assigns
the IP address, subnet mask, gateway
and name server to a network device.
DHCPs are available in current routers.
The DHCP service must be specially set
and activated (see the corresponding
manual for more information).
Note:
When using fixed IP addresses and a
DHCP server, make sure that the fixed IP
addresses are outside the address range
assigned by DHCP. Otherwise, problems
could occur.
Port
A port is an interface used for communi-
cation by different programs. Certain
ports are fixed (21: Telnet, 23: FTP),
whilst others can be freely selected.
Ports are important for different applica-
tions (e.g. external access to the device
over a browser).
MAC ad-
dress
The MAC address (Media Access Con-
trol or Ethernet ID) is the specific hard-
ware address of the network adapter.
This is used for the unique identification
of the device in a computer network.
Network layout
The device must be physically connected to the network
over a CAT5 cable (see connections on page 3).
Several switches, routers and access points can be con-
nected to each other. Firewalls and other security soft-
ware can affect the network.
Warning
When using a router, the network clients (e.g. the
recorder) can be connected to the Internet and
vice versa.
Make sure to use protective measures to prevent
unauthorised external access (e.g. firewall, chang-
ing passwords, changing ports)!
Network configuration
The device must be configured using the Network menu.
IP
IP address of the recorder in the
network (manual assignment).
To assign the IP address by DHCP,
enter the IP address as 0.0.0.0. The
recorder must then be restarted.
Port
Port 8000 is the standard port for ac-
cessing the recorder via the network.
Mask
Usually 255.255.255.0.
Gateway
Address of the gateway for Internet
access.
Http Port
Port 80 is the standard port for ac-
cessing the recorder web server.
Used to specify the e-mail settings
which are sent as an email to a spe-
cific address in the event of an alarm.
Advanced
MAC address, network speed, DNS,
Multicast and NTP.
