INTRODUCTION
The purpose of this manual is to provide the GEWISS sales force with basic technical
knowledge about the City Vision video entryphone system.
The system manual is structured as follows:
•The first part describing the system and devices
•The second part describes application examples
•The third and last part is dedicated to FAQ
The document is structured so it can be used easily both when read completely, which is
recommended at least once in order to understand functions and possibilities of the system,
as well as when specific sections are read to quickly clarify doubts or to review specific
arguments before going to meet with a customer or before making a presentation.

THE SYSTEM
The system is based on three basic elements: the indoor positions, the power
supplies/enclosures and the outdoor positions. It uses 2-wire technology with the option of
extending the system using IP technology, which makes it possible to use dedicated LAN
infrastructures or LAN infrastructures shared with other systems.
System architecture includes two types of distribution or connection:
- horizontal, also called backbone, with which the outdoor positions are connected to
the power supplies/enclosures; see the red line in the diagram below.
- the vertical one, also called upright, with which the indoor positions are connected to
the power supplies/enclosures; see the yellow line in the diagram below.
The upright consists of a 2-wire cable that transmits audio and video signals, with analogue
modulation, in a similar manner as with TV antenna systems. The power supply for the indoor
positions is also available on the same cable together with the audio video signal.
This brings us to the first two important considerations regarding 2-wire technology:
•the audio/video signal is transmitted in an analogue mode
•both the audio/video signal as well as the power supply for the indoor positions are
transmitted via the same duplex cable; therefore, all indoor positions are connected
only via a duplex cable, with the exception of the NAXOS indoor position (as will be
explained later), which must always be powered separately.
The analogue transmission of the audio/video signal requires a few plant-engineering
aspects, the most important of which are:
•Line impedance: the impedance must be correctly adapted via specific devices and
settings (just as in the case of TV antenna systems).
•Limit distances: there are limit distances that must be respected when connecting
various devices together, due to the weakening of the signal along the cable.
•Exceeding the limit distances: accessories are available for exceeding the limit
distances, which act as signal amplifiers and regenerators

Main functions of the system:
- Privacy
- Landing call function from an indoor position
- Door opener from an indoor position
- Door opener from an outdoor position
- Video control
- Auxiliary commands
- Intercom:
obetween indoor positions in the same apartment
obetween indoor positions in different apartments
- Video answering machine
- Call notice during an intercom conversation
- Call transfer
- Contemporaneous calls on the LAN backbone
System programming:
- Manually via associations between the outdoor position and indoor positions
- Via PC with software connected to the system power supply
System classification according to the different types:
•2-wire systems with 1 level backbone: to implement single-family homes or small sized
buildings, with a single building or block, the building can also have multiple staircases
(uprights).
•2-wire systems with a 2 level backbone: to implement medium and large sized residential
complexes with multiple buildings or blocks.
•2-wire systems with IP/LAN extension: to implement large sized systems for residential
complexes with multiple buildings or blocks where the connection between buildings is via
the LAN network.
Notes:
•the term “2-wire” used for each type of system refers to the uprights, which for all
types, has 2 wires.
•The term “IP extension” can be associated with systems with the physical presence of
a LAN network as well as with normal installations”; these devices also include
different types of outdoor positions: KARALIS and ANTAS, the system power supply
GW19351, the telecamera selector GW19359 and the auxiliary relay GW19360.
The following paragraphs describe the various types of systems defined above in more detail.

Chorus City Vision - Technical System Manual Page 7
2-WIRE SYSTEMS WITH 1 LEVEL BACKBONE
This type of system makes it possible to implement video entryphone systems for small sized
systems:
•Applications: single-family homes or small sized buildings, with a single building or block,
the building can also have multiple indoor staircases (uprights).
•Architecture: the system may also consist of one or more uprights (one per staircase), but
there is a maximum of only one system power supply, type GW19301 or GW19351, to
which the outdoor positions are connected; in more simple systems, instead of a system
power supply, there can be a simple power supply, type GW19302 or GW19303.
The connection between the outdoor positions and the system power supply
GW19301/GW19351 is called a backbone connection.
•Limits using the system power supply GW19301:
oUp to 3 outdoor position (one can be the main one)
oPassage control (with PE KARALIS)
oUp to 108 apartments per building
oUp to 8 indoor video entryphone positions per apartment
oUp to 8 videocameras per video control
oIntercom inside the same apartment or between apartments
oUp to 2 block porter's desks (with GW19202 WH/BK)
•Limits using the system power supply GW19351:
oUp to 4 outdoor position (one can be the main one)
oPassage control (with PE KARALIS and PE ANTAS)
oUp to 108 apartments per building
oUp to 8 indoor video entryphone positions per apartment
oUp to 12 videocameras per video control
oIntercom inside the same apartment or between apartments (an additional device
is necessary)
oUp to 2 block porter's desks (with GW19202 WH/BK)
Main connections:
in yellow, the connection of the 2-wire uprights
in red, the backbone connections: with 4 wires with system power
supply GW19301, with 8 wires with system power supply GW19351

Chorus City Vision - Technical System Manual Page 8
2-WIRE SYSTEMS WITH 2 LEVEL BACKBONE
This type of system makes it possible to implement video entryphone systems for medium
and large sized systems:
•Applications: medium and large sized residential complexes with multiple buildings or
blocks.
•Architecture: the system may consist of one or more uprights per building, one per
staircase; each building has one system power supply GW19301 to which the building's
secondary outdoor positions are connected, all the power supplies GW19301 are
connected to a system power supply GW19351 to which the main outdoor positions
common to all buildings are connected.
The connections for the secondary outdoor positions for the individual buildings to the
respective power supplies GW19301 are called second level backbone connections.
The connections for the main outdoor positions common to all the buildings to the
respective power supplies GW19351 are called first level backbone connections.
•Limits:
oFor each building:
Up to 2 outdoor position
Up to 108 apartments per building
Up to 8 indoor video entryphone positions per apartment
Passage control (with PE KARALIS)
Up to 8 videocameras per video control
Intercom inside the same apartment or between apartments
Up to 2 porter's desks (with GW19202 WH/BK in the Gewiss 2014
catalogue)
Up to 4 videocameras for video control, visible in the single building
Up to 2 block porter's desks for each block (with GW19202 WH/BK)
oFor the entire complex:
maximum 64 buildings
Up to 4 main outdoor positions (with possible passage control)
Up to 2000 apartments (with PE ANTAS)
Intercom limited to the apartments in the single block and not possible
between different blocks
Up to 12 videocamera per video control, visible to all (with GW19359)
Up to 2 main porter's desks (with GW19202 WH/BK)
Even though large sizes can be reached, it is recommended to limit this type of system to a
few blocks, due to functional limits and those caused by distances.

Chorus City Vision - Technical System Manual Page 9
The following figure shows an example with 5 blocks, each with a single staircase.
Main connections:
in yellow, the connection of the 2-wire uprights
in red the second level backbone connections have 4 wires
in violet the first level backbone connections have 8 wires
the part marked in blue indicates one of the 5 blocks

Chorus City Vision - Technical System Manual Page 10
2-WIRE SYSTEMS WITH IP/LAN EXTENSION
This type of system makes it possible to implement video entryphone systems large and very
extended systems:
•Applications:
olarge sized systems for residential complexes with multiple buildings or blocks
where the connection between buildings is via the LAN network;
oSmall sized systems (small number of residential units), but where the distances
are considerable, e.g.: individual family residences where there is a large distance
between the entry gate and the home.
Large distances can be easily covered using an optic fibre connection.
•Architecture: the system may consist of one or more uprights per building, one per
staircase; each building has a system power supply GW19351 and a LAN interface
GW19356, thanks to the LAN interfaces GW19356 all the bulidings can be connected
together via the LAN network.

oFor each building:
Up to 4 outdoor position
Up to 108 apartments per building
Up to 8 indoor video entryphone positions per apartment
Passage control (with PE KARALIS and PE ANTAS)
Up to 12 videocameras per video control per IP-extension block (with
GW19359) and possibly another 4 for each individual 2-wire block
Intercom inside the same apartment or between apartments
Up to 2 porter's desks (with GW19202 WH/BK)
oFor the entire complex:
oUnlimited number of buildings
oUnlimited outdoor positions (above 108 apartments, PE ANTAS is
necessary, which manages a max of 2000 calls)
oUnlimited no. of apartments
oUp to 8 indoor positions per apartment
oIntercom limited to the apartments in the single block and not possible
between different blocks
