DOOR PHONE - VIDEO DOOR PHONE SYSTEMS: Installation - Urmet

“1+1” wire door phone system
VIDEO DOOR PHONE SYSTEMS
Coax systems
The construction of a coax video door phone system is similar to that
of an electronic call “4+n” door phone system with the addition of video
functions. The wires are the same as those shown for the door phone
system with the addition of those needed to power the camera and the
monitor, in addition to the coax cable for the video signal.
This system offers countless possible confi gurations for both black and
white and colour installations; it is particularly indicated when there is
a long distance between the camera and the monitors.
Apartment stations in coax systems can be connected one to another
to make intercom systems.
Apartment stations in coax systems can be complemented with a
wide range of accessories (three-tone gong, Scaitel picture memory
module, supplementary buzzer, etc.).
Simple “4+n” door phones can be connected to the coax video door
phone system for offering voice service only.

for transforming existing door phone systems into video door
phone systems without addition other wires in the column and the
apartments.

used to make video door phone systems with only 4 wires for powering
the monitor and the video signal plus 1 wire for the call signal.
The picture only appears on the called monitor. Conversation is private.
