Port
A port is an interface that enables differ-
ent programs to communicate. Certain
ports are fixed (23: Telnet, 21: FTP),
whilst others can be freely selected.
Ports are relevant for various applica-

vice via a browser.
MAC Ad-
dress
The MAC address (Media Access Con-
trol address or Ethernet ID) is the specific
hardware address of the network
adapter.
It is used for the unique identification of
the device on a computer network.
Network layout
The device must be physically connected to the network
via at least a CAT5 cable.
Note
Please follow the instructions and notes for the
network devices.
Several switches/routers/access points can be connected
to one another. Firewalls and other security software may
have a negative effect on the network.
Warning
When using a router, the network clients, and
therefore the recorder, are "connected" to the in-
ternet and vice versa.
You should make sure that you take protective
measures, such as using a firewall, changing your
password and changing the port, to prevent unau-
thorised external access.
