device or cause poor transmission quality. The warranty automatically
expires if you use a different power supply unit.
The power supply unit is plugged into a wall socket inside your
N OT IC E
house, usually where the two wires from your assembly location
come out of the wall in the interior of the house.
The provided mains adapter is not outdoor-ready and for
indoor-use only.
OPTION 2
Power supply and network connection using PoE
(Power over Ethernet)
To power the device via a PoE-Switch (e.g. D-Link DGS-1008P) or PoE-
Injector (e.g. DoorBird Gigabit PoE Injector A1091), use a CAT.5 cable or
higher in accordance with the PoE standard IEEE 802.3af Mode A.
A CAT.5 cable or higher must be used for this purpose, as network signals
can only be transmitted over completely insulated, shielded and twisted
cables. If you use PoE as a source of power, the four wires for PoE then
simultaneously form the data line. The device will not start if your PoE-
Switch/PoE-Injector does not support the PoE Standard IEEE 802.3af
Mode A.
Do not combine the power supply from the power supply unit
N OT IC E
(mains adapter) with the power supply via PoE.

1. Disconnect the PoE-Switch or PoE-Injector from the power grid.
2. Place the network cable in the installation site of the device.
OPTION 3
Power supply using a DIN rail power supply unit
Alternatively to the mains adapter, we offer DIN rail power supplies in
our online shop, which can be installed by a specialist. The network
connection is then made via a network cable or alternatively via WiFi.

CONNECTING THE DEVICE
It is possible to connect the cables and wires to the device conveniently
and safely via the labeled screw connection terminal. You can connect all
necessary cables and wires to the device now.
Please remove any cables and wires from the connection ports
N OT IC E
of the device that you do not need.

If you must power more than one device
with one power supply , we recommend
to use a PoE-Switch with PoE Standard
IEEE 802.3af Mode A or an appropriate
DIN rail power supply (see "OPTION 3").
Theoretically (not recommended by us!),
an unshielded, but over the whole length
(max. 80 m/262 ft) twisted bell wire with
two pairs of wires (first twisted pair of
wires: "T+, T-", second twisted pair of wires
"R+, R-") can be used for the network
and PoE transmission as an alternative
to a Cat.5 network cable or better. This is
comparable to a Cat.3 network cable. In
this case, however, we cannot guarantee
the data throughput or the stability of
the network connection and power sup-
ply; this must be measured and checked
on site by qualified personnel over several
hours (network data is transmitted at
high frequency, therefore a shielded Cat.5
network cable twisted in pairs or better
must normally be used).
For easier installation we strongly recom-
mend to remove the plug from screw
connection terminal while you connect
the cables and wires.
