Introduction

Installation requirements

When determining the camera position of a
Behnke door intercom station, please bear in
mind the following:
In order to receive an image feed, you need a
lot more than to simply point the camera in the
direction of an object or a person. The lighting
situation, the camera's angle of view (horizontal
/ vertical), reflectance from other light sources
and sunlight, back lighting and blind spots all
have an influence on your future image quality.
It is important that you avoid direct sunlight, as
the camera shutter will reduce light incidence
into the camera and consequently will reduce
the image sensor performance. Therefore, try to
have the sun behind the camera when choosing
your camera position. In order to prevent prob-
lems from back lighting when filming objects or
people, you should consider changing the sur-
rounding area by changing the camera position.
Where it proves to be impossible to change the
camera position, the object or person in ques-
tion should be sufficiently lit from the front.

Outside mounting

▸
When using your door intercom on a weather
side, the Series 20, 30 and 40 intercom sta-
tions should be mounted in-wall with a rain
protection cover (Please always ensure the
included seal is correctly put in place).
▸ When mounting your Series 5, 10, 20, 30, 40
and 50 door intercom in an on-wall housing, it
is possible to route the cables to the bottom
or the rearside of the on-wall housing.
▸
Use the included cover angle to cover the
cable route not in use. Use the PG screw
connect for cable entry.
▸
All in-wall mounted door intercom stations
mentioned in the present manual need to be
well sealed against rain water entering into
the housing, esp. with an uneven under-
ground (e.g. using silicone). Please leave
the center of the bottom edge of your door
intercom station (Series 20, 30, 40 and 50)
open to serve as a water drain. When using
cover panels (for Series 5, 10, 20, 30 and 40),
the cover panel needs to be sealed with a
suitable sealing agent or with the included
seal against the in-wall housing or the level
surface for cavity wall mounting.
▸
For mounting in steles by third-party provid-
ers, appropriate action needs to be taken to
prevent condensation water from forming
inside the pillar.
