PREPARE POWER SUPPLY
The device does not have a battery as power supply, therefore, choose one of the following options.
OPTION 1
Power supply using the power supply
unit (mains adaptor)
To power the device using the provided mains
adapter, 2 insulated wires are required. The power
supply unit has a 300 cm (9.8 ft) long cable with
two insulated wires. The network connection is then
established via a network cable or alternatively via
WiFi.
The provided mains adaptor is only capable
to power one device. It is not designed to
power multiple devices simultanously.
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”).
NOTICE
Do not plug the power supply unit into the
wall socket yet.
Only use the power supply unit provided
along with the device, or a DIN-rail power
supply unit (see “OPTION 3”) that you can
obtain from us separately, since this has
been specially stabilized electrically and
is equipped with an integrated audio
interference reduction device. Other power
supply units may destroy the 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 house (Step 10), 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, it is 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.
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 supply; 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).
NOTICE
Do not combine the power supply from the
power supply unit (mains adaptor) 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.
