INSTALLATION
All steps below should be carried out carefully by a competent adult, taking
into consideration any applicable safety regulations. Should you have any
questions, please contact us or a competent specialist directly. Please ensure
that all wires used for the installation are undamaged along their entire
length and approved for this type of use.
Network speed and network components
Please ensure that the upload speed of your Internet connection is at least
0.5 Mbps. You can also carry out a speed test at any time via the DoorBird
app. The user experience is only as good as your network speed, network sta-
bility and quality of your network components, such as your Internet router
and WiFi access points or WiFi repeaters. Please also make sure that your net-
work components are no older than two years old, have been manufactured
by a well-known manufacturer, and have the latest firmware installed.
Should these requirements not be fulfilled, it may occur, for example that the
performance of audio and video is poor or push notifications are delayed or
do not arrive on your smartphone or tablet at all.
High-speed Internet (via landline): DSL, cable or optical fibre
Network: 802.11b/g/n 2.4 GHz or Ethernet, with DHCP
STEP 1: SWITCHING OFF POWER
Switch off the power to all wires leading to the assembly location, i.e.
the door station, door chime, electric door opener, power supply unit, PoE-
Switch / PoE-Injector etc.
STEP 2: DISMANTLING THE EXISTING DOORBELL
Should there already be a doorbell on the exterior wall of the house, please
dismantle it.
STEP 3: DETERMINING THE ASSEMBLY LOCATION
The video door station uses an ultra wide-angle hemispheric lens so that
even when the person is a minimum distance of 50 cm (19.68 inches) away
from the video door station, a low installation height is sufficient. The lens is
therefore not mechanically adjustable. The camera lens should be located
at an altitude of at least 125 cm (49.22 inches). You may check this prior to
the final mounting. Press the mounting plate against the wall at the desired
installation site and mark the boreholes with a pencil. Remove the mounting
plate again. Ensure that no cables are to be found in the wall behind
the boreholes.

STEP 4: POWER SUPPLY
The video door station can be powered by two simple doorbell wires using
the power-supply unit (mains adaptor) supplied with it or via PoE (Power
over Ethernet) using a network cable. The video door station can alternatively
also be supplied with a DIN-rail power supply unit can be obtained from us
directly.
The video door station does not use battery power. The use of a mains power
supply permits the transmission and display of on-demand live video at any
time and not only if a visitor has pressed the doorbell.
Power supply using the power-supply unit (mains adaptor)
Two insulated wires are required to power the video door station by plugging
it into the mains. These wires are normally already there and are freely
accessible once you have removed the previous doorbell. Only use the power
supply unit provided along with the video door station, or a DIN-rail power
supply unit can be obtained 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 video door sta-
tion 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, usually where the two wires from your
previous doorbell come out of the wall in the interior of the house.
Do not plug the power supply unit into the wall socket yet. Connect the power
supply unit inside the house with the crimp connector provided and the two
wires that you would like to use to power the device.
Power supply via PoE (as an alternative)
To power the video door station via a PoE switch (e.g. D-Link DGS-1008P) or
PoE injector (e.g. DoorBird Gigabit PoE Injector A1091) in accordance with
the PoE standard IEEE 802.3af Mode A, the four wires bearing the numbers
1, 2, 3 and 6 of a Cat.5 network cable or better are to be used. A Cat.5 cable
or better must be used as network signals can only be transmitted over
completely insulated, shielded and twisted cables. If you use PoE as a source of
power, the WiFi interface of the video door station is automatically deactivat ed,
and the four wires for PoE then simultaneously form the data link. The video
door station won't start if your PoE Switch or PoE injector does not support the
PoE Standard IEEE 802.3af Mode A (see Diagnostic-LED and Diagnostic-Sounds).
1. Disconnect the PoE switch or PoE injector from the power grid.
2. Place the network cable in the installation site of the video door station.
Do not combine the power supply from the power supply unit (mains adaptor)
with the power supply via PoE.
