SWITCHING OFF POWER
Switch off the power to all wires leading to
the assembly location, i.e. the door chime,
electric door opener, power supply unit for
the video door station etc.
DISMANTLING THE EXISTING
DOORBELL
Should there already be a doorbell or door station on
the exterior wall of the house, please dismantle it.
DETERMINING THE ASSEMBLY
LOCATION
The device uses an ultra wide-angle hemispheric lens
so that even when the person is a minimum distance
of 50 cm (19.68 in) away from the device, 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 145 cm (57 in).
You may check this prior to the final mounting.
When choosing the assembly location, consider
the lighting conditions. Avoid direct sunlight, direct
backlight and reflective surfaces.
Do not expose the device to direct sunlight.
N OT ICE
The housing temperature can exceed the
maximum allowed temperature limit. This can
result in damage of electric and mechanic
components of the device and injuries
especially when touching exterior parts of the
device. White and bright silver-colored front
plates absorb less sunlight than dark ones.
An image sensor must not be exposed to
N OT ICE
direct sunlight for an extended period of time.
Direct sunlight will "blind" the camera and
may permanently bleach the small color filters
on the image sensor chip.
Any defects caused by direct sunlight are not
covered by warranty.
The network cable between the device and the
PoE-Switch/PoE-Injector/Internet Router can have a
maximum length of 80 meters/262 feet (IEEE 802.3).
If you have only two wires available at the
assembly location, you may use of the
"DoorBird 2-Wire Ethernet PoE Converter
A1071", sold separately. It allows you to
transfer network data (Ethernet) and power
(PoE) with a simple two-wire cable over
long distances. For example; existing buil-
dings with a simple two-wire bell wire can
be equipped with network technology wit-
hout having to retrofit any network cables.
