Wiring for Audio and Video Doorphone

There could be no lack of wiring to mount doorphones and video doorphones in our online store. Formerly, with analogue doorphones there was only one type of cable, which was a N-wire hose, as many as needed per home plus 4 extras that were used in common. In other words, 4+N analog technology. This means that in a building with 50 neighbors, the installer found a 54-wire street panel, that is, an intractable tangle.

Over the years, technologies have been improved, and with digital and its different versions the number of necessary cables has been reduced, but the variety of cables with which an installation can be made has been expanded. That we will see in this section.

Doorphones and video doorphones can be basically divided into two technologies. Analog and digital.

The analogue doorphones of a lifetime are also called conventional doorphones or 4 + N system, more technically speaking. They use 4 common wires and 1 extra wire for each house, which is used for the call.

For an installation of one or two houses, the 6-wire cable we have can be used. The section of the 0.25mm or 0.50mm cable will depend on the distance and above all on the technical specifications of the gatekeeper's own manufacturer.

In analog video doorphones, the same rule as the previous one applies, but we also found a coaxial cable for the video image. Coaxial cables you have in our section of coaxial cables.

In digital door entry systems we can distinguish two technologies for the Fermax brand, VDS and DUOX.

• VDS system: It is a system that only uses 3 wires in audio and in a video door phone with 5 wires it is enough. Supports variety of wiring. With this technology, Fermax was launched on the market with the slogan “Change from doorphone to video doorphone with Fermax” because the existing convention doorphone wiring in a building could be reused to mount a video doorphone. It can also be wired with UTP cable, or with coaxial + 3 wires or with 5 wires in hose. That is why you can find cheap UTP cable in this section.
• DUOX system: Replaces the old BUS2 system (although they are not compatible with each other), it allows the installation of 2 non-polarized wires in the installation. Simplifying the wiring. The ideal wiring for this system are two parallel wires with a section of 1 mm. But it is a multipurpose system and it can even admit another type of cable, although it may be necessary to carry out an exhaustive review of the installation to make sure that the cabling is usable. Parallel cable is also available.
