A wireless intercom with an external panel will work well for a single-family home. Other types of intercoms are also available, such as analogue-digital intercoms . Video intercoms are also worth considering, as they are easy to install and have cameras. Of course, you can opt for a uniphone with which you can open the gate door. It is worth noting that both wireless and wired intercoms are absolutely essential in single-family homes.
They have volume control and a microphone, which can be used to communicate. In turn, video intercoms can function as monitoring, which undoubtedly improves the level of security. It is worth remembering how important proper installation is. This type of equipment, such as an intercom, is easy to install, even on a building or block, but you need to choose the right cables. Basically, you can say that this type of device should have three colors of electric cables.
Each of them has a specific function. Namely, the brown or black wire is the phase wire, while the blue color is the neutral wire, and the yellow-green cable indicates the protective wire. In the case of intercoms, functions play an important role. They also make this type of equipment easy to use. The red cable is responsible for the power supply. The white cable is the audio signal, or simply the microphone, while the blue cable is the signal to open the door.
There is also a yellow cable, which can be treated as an additional signal or reserve cable. To properly connect the intercom, the black cable should be placed in the terminal, while the green one should go to the terminal marked with a loudspeaker symbol. As we mentioned, the blue cable is a signal for opening the door, but it can also be connected to a wicket gate or even a gate. The internal receiver allows for communication, which in turn is the responsibility of the external panel.
How many wires should there be in an intercom cable?
As you know, there are different types of intercoms. Which intercom to choose? It all depends on your preferences. Inside the building, you need to place a power supply that is connected to the electrical network. Of course, there are models available that are already equipped with a power supply located inside the intercom. In addition, remember that it is necessary to select a cable with the right number of wires. Therefore, when choosing an intercom, remember that it should be easy to use. However, for the connection to be correct, you should choose a two-wire electric cable with a cross-section of 1 to 1.5 mm2.
Of course, everything largely depends on the distance of the power supply from the cassette. The intercom cable has at least a few separate wires. As standard, the simplest models have two of these wires. However, there are models that have significantly more wires. It should be known that one function is assigned to one wire. So if you want to gain not only a microphone, but also a door opening, camera or lighting function, the number of wires must be greater.

How to choose the right cable for an intercom?
When choosing an intercom, you should focus on quality, and also choose one that has a strong microphone. However, these are not the only functions that matter. In order for the intercom to function properly in the installation, you need to find the right intercom cables .
It is recommended that the intercom power supply be routed in a separate electrical cable. A two-core cable with a cross-section of 1 to 1.5 mm kW will work best. In addition, the cable must be selected depending on the distance of the power supply from the cassette. If the distance is not large, i.e. up to 20 meters, then a regular signal cable can generally be used. Digital intercoms use three cores plus one core, which is used for power supply. Such a connection is very durable.
To connect the exit button, you should use a signal telecommunications cable. It should be routed from the intercom electronics board to the bell button. However, any two-core cable can be used to connect the electric strike. The cross-section must be selected for the intercom panel. Before laying the cables and installing them, you must always familiarize yourself with the device diagram and arrange the cables so that there is a reserve. This is important because if a cable is damaged, you do not have to have an additional cable and replace the entire wiring.
How to properly connect a wired intercom?
You already know which intercom to choose. However, in order for it to work properly, it must be properly connected. The external panel is placed on the building. In the house, there is a power supply and a device that allows for full management of the work. Proper connection of the intercom is also crucial.
First, you need to connect the cable that is responsible for the power supply, the so-called ground. In the next stage, you need to connect the wire that allows the speaker to operate. Finally, you install the wires that are responsible for the microphone, as well as releasing the electric lock, which fully cooperates with the intercom.
