In this category you will find a wide selection of articles for installations of intercom and video entry to the house or even business premises. The intercom has become with the years an electronic system essential to communicate with the outside of the house,not only allows you to communicate with whoever is at the entrance of the front door of the house but also to open the electric lock, and with service buttons additional the intercom can also turn on the lights of the courtyard or the electric gate for the passage of a car. The intercom system is usually composed of a pulsatiera external,a power supply and the intercom handset inside. The video instead has the same functions but with the addition of a camera that not only allows you to listen to someone who is at the gate, but also see it through the monitor of the video door phone which is installed inside the apartment. The video within and in addition to have the classic handset also has a small monitor that allows the view of the camera placed on the external pendant. The push-button panels external are also equipped with led night vision-so as to identify the person even in the dark. Recently, major companies such as Bticino,Urmet and Comelit have also been introduced to the market video-entryphones and intercoms , hands-free,i.e. it is possible to talk and listen without using the handset. When you choose a system entry, you must first determine if you opt for the system 2-wire (2voice) or one 5-wire, also called 4+n because of the 5 elements in place, 4 are common. For example, if in an apartment, you need to install two door phones, you will have to enter in cable 4-wire common to both and 2 separate wires for each device, the members, the latter useful to ring the individual intercom. The 4 common wires are for the mass, for the audio signal from the internal microphone to the external one, then for the audio signal from the external microphone to the inside, another for the opening of the lock of the front door entrance.
