Port A port is an interface used for communi-
cation by different programs. Certain
ports are fixed (23: Telnet, 21: 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
address 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 the connections on page 66).
Note
Pay attention to the specific information and in-
structions on the network devices.
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)!
