An intercom facilitates communication between the interior and exterior of a home.
Citófono is an acronym : that is, a word that is created by joining elements of different terms. In this case, the concept arises from the association of components of the notions of circuit and telephone .
In the field of electronics , a circuit is a system that an electric current can travel through. This system is made up of conductors and devices that produce or consume said current. A telephone , meanwhile, is a device that allows sounds to be transmitted using electricity.
What is an intercom
Returning to the idea of intercom , which is used in Colombian territory, it refers to the system that makes possible the development of communication within the framework of a closed telephone circuit . This is the device that, in other regions, is known as an electric intercom , electronic intercom , automatic intercom , electric intercom , telephone , intercom , interphone or intercom .
The most common use of the intercom is to establish communication between the interior and exterior of a home . In this way, when someone arrives at a house, they can press the intercom bell ; If a person responds from within, a telephone-type dialogue is established.
The intercom, therefore, provides security . Whoever is in your home can listen to whoever is outside through the intercom and know what they want, having the option of finally opening the door or not. It should be noted that, sometimes, the intercom is connected to an electric door opener that is activated by a button, so it is not necessary for anyone inside the building to go out and open it.
Currently, intercoms are usually associated with cameras.
Origins and evolution of the device
Typically, intercoms are installed in apartment buildings or apartments . Its creation allowed, at first, the building manager to transmit messages to the different owners or tenants.
Then, especially with the implementation of the electric door opener, the management of the entry and exit of people into the building was facilitated. By having each unit with a specific bell on the intercom, communication from home to street / street to home is very simple.
Nowadays, the electronic intercom is not just a closed-circuit telephone. It is often associated with a camera and it is possible to observe the images through a screen or monitor inside the house. On the other hand, sometimes they are no longer based on the use of cables, but can be digital and use wireless connectivity .
Doorphone maintenance
Like any electrical or electronic equipment, the intercom requires preventive maintenance to avoid damage. Cleaning is essential to ensure proper functioning of the circuit.
In some cases, deterioration of cables and failures of electronic components make the intervention of a technician essential. The solution to the problems is usually in the hands of the system installer himself, although each situation is particular and it is likely that the service of another professional will be required to reestablish communication.
