“Domotics” comes from Latin word “Domos”, which means “home”, with the suffix -tics, which indicates the field of application: building a home automation means therefore identifying new ways to apply technology in the home, with the aim of improving the living comfort of the residents, and making the building more efficient and safe.
Through the installation of high-tech systems connected to each other, it is possible to create a smart home in which the lighting of the lights, the monitoring of the external perimeter, the opening of gates and shutters can be controlled from a single central system, room temperature and much more. This centralized control can be exercised with special devices installed inside the home or by means of applications for computers and mobile devices, so that it is possible to have full control over you home even when you are away.
Home automation works thanks to the BUS, electronic systems that allow the systems to exchange information with each other by means of supports such as coaxial cables, optical fiber, twisted pairs and electrical cables or via wireless and infrared signals. To make a home automation system, it is therefore necessary to install compatible systems and set up a BUS system for communication between them.
Home automation is also ecological, because centralized management allows you to reduce energy waste and simplifies the implementation and control of plants for the production and consumption of electricity from clean sources, such as photovoltaics.
Although connected to the term 'home', the concept of domotics is also extended to industrial and commercial applications, since the principle of connection, communication and centralization of the systems allows to make both shops and industrial plants more efficient and safer.
A residential photovoltaic system allows the user to produce energy independently, drawing on a clean and renewable source.
A domestic photovoltaic system works like this: the sunlight hitting the panels transfers its energy and allows you to create a direct current flow that is directed towards an inverter, which converts it into the alternating current used in our homes. Based on the sun exposure conditions and the size of the system, photovoltaics can cover a sensitive portion of the electrical needs of a family unit; it is also possible to integrate a photovoltaic storage system that acts as a battery, storing electricity not immediately used to consume it at night or in bad weather, and enhance the system's performance.
There are some factors that have to be considered for the installation of a photovoltaic system, as the size and orientation of the roof and the presence of any shading. In the case of properties in areas without constraints (environmental, historical, landscape) the communication to the network operator is required through a document for the construction, connection and operation of small photovoltaic systems integrated on the roofs of buildings, otherwise it is required the authorization from the competent authorities.
A building with a photovoltaic system remains connected to the power grid, so that you have guaranteed electricity regardless of weather conditions and to carry out the exchange on the spot, or the 'sale' to the network manager of the electricity produced which exceeds the requirement in a given moment.
A photovoltaic system offers important advantages both for the user, by reducing utility bills and amortizing the installation cost in a few years, and the environment.
Automatic gates allow you to control access to a residential, commercial or industrial property, and at the same time maximize the comfort of people entering or leaving, who do not have to get out of their vehicle or make physical efforts.
Automatic gates work thanks to a control unit that receives a signal and activates a motor that allows you to move gates, garage doors, overhead doors and bars; their movement can be swing, with rotation around a fulcrum, or sliding, reducing the size required for installation.
Automatic gates are also integrated with photocells, a pair of sensors in which one sends an infrared signal and the other receives it: if this signal is interrupted, for example by a vehicle or a person, the control unit stops opening or closing the gate, allowing passage without incident.
Automatic gates are activated by special remote controls, but you can also use your mobile phone for greater convenience.
Video surveillance systems are used as a deterrent against illegal activities, recording what happens in a residential, commercial or industrial area with cameras that can be activated 24 hours a day, 7 days a week.
A video surveillance system involves the installation of wired cameras for power supply and a network, with or without wires, for the communication of video data, which can be sent to DVR systems (Digital Video Recorder) to store the recordings or directly to tablets and smartphones for direct monitoring of the area under surveillance.
To install a video surveillance system you need to know a few things. Different models of cameras have different range and it is therefore appropriate to evaluate their position to minimize the so-called shadow areas, i.e. the areas not framed by any device.
In the same way the zoom, the definition of the image and the night shooting capability differ from model to model; finally, HDCVI systems are available that convert the analog-digital signal, and IP systems, which generate a signal already digitized and ready for wireless transmission.
Perimeter alarm allows you to protect the perimeter of a residential, industrial or commercial area by using sensors that activate in response to movement: in this way it is possible to signal (and therefore prevent) unauthorized entrances.
The installation of a perimeter alarm must be preceded by a careful assessment of the area to be secured, to define threats and therefore identify the most suitable technological solutions: microwave or infrared sensors, visible or underground, can be used.
Once the perimeter alarm has been activated, every movement in the area protected by sensors is detected, triggering various responses, such as audible alarms or signals to operating centers that contact public or private law enforcement agencies.
It is also possible to control the sensors through the app, activate or deactivate specific areas to allow the passage of authorized people and calibrate them so as not to accidentally shoot in the presence of animals.
Industrial electrical control systems are used to spread electrical energy within an industrial group: consequently, they require levels of performance and complexity much higher than their civil counterparts and are subject to periodic checks and strict design and installation standards to ensure the safety of personnel operating within a complex.
In this context, machinery requires large quantities of energy and therefore the plant must be able to manage them adequately without short circuits or overloads.
The regulations for industrial electrical control systems refer to Law 186 of 1968 on the materials used, to Presidential Decree 462 of 2001 on the periodicity of operational checks, to Legislative Decree 37 and 81 of 2008 on the safety of systems and workplaces respectively, and CEI 64-8 for the use of differential switches and protection from indirect contact with electricity.
Home theater system aims to reproduce the visual and auditory sensations of a cinema projection through the careful design of the room space, the selection of the audio/video devices used and their installation in the most appropriate positions.
For this purpose, television screens or video projectors, speakers are used to create the surround effect and multimedia playback systems.
It is also possible to connect the system to mobile devices not only to control playback, but also to send digital content and synchronize it with entertainment applications.
Background music systems allow you to play the same audio track in several places at the same time, using a system of synchronized and centrally controlled speakers.
Background music systems are widespread in commercial realities to create a pleasant environment for consumers, but they also find space in the home, allowing the inhabitants of the house to listen to music tracks in every room, even distant from the main audio system.
To create a background music system it is necessary to evaluate the area to be covered, consequently determining the technology used (cable or wireless), the position and size of the speakers (with any recessed), and how to control the audio reproduction.
Video intercoms facilitate communication with external people who require access to a residential, commercial or industrial area, and allow them to be identified more easily, with important consequences for safety.
The complexity of the system varies according to the context of application, but in general the installation of a video intercom requires a two-wire cable and a cable to connect the external device to the internal one, and a corrugated for power supply.
If there is a previous system, it is also possible to take advantage of the already installed equipment to switch from the simple intercom to the video intercom or to implement more modern and efficient models.
