Wired

Until recently, this was the most common type of home automation system. A characteristic feature of this option is wired connection of the components. Sensors, detectors, switches, outlets and other equipment are connected by a single information bus, which has the form of a special cable. In some cases, a simple twisted pair cable can be used.

The main advantage of a wired system is its high reliability. Signals from sensors go to a controller, actuators by wire without any interference. This type has also other benefits:
A low delay between giving a command and its execution. Signals go very quickly over an information bus, making control of the smart home systems comfortable. When the delay is high, it takes a long time to wait; repeated commands clog the bus, as a result, it may hang up.
Ample opportunities for integration into the scheme of external devices. To connect a wired Smart-Home to climate control, heating and other stationary equipment is much simpler than a system that works wirelessly. Thus, wired schemes are more multifunctional.
Long service life and easy maintenance. Smart equipment connected via an information bus does not need additional power sources. You do not have to change non-rechargeable and rechargeable batteries. The resulting benefit is non-frequent and simple maintenance of the devices.
The disadvantage of a wired Smart-Home is its rather complicated installation. The hidden work on installing a bus requires carrying out dirty work of wall chasing. Cable channels do not always look attractive, do they?

                                                                                                                 Special aspects

If you decided to install a wired system, you will have to plan in advance where the switches and outlets will be mounted. Besides, the installation of a wired scheme has a lot of other special aspects:
• A well-developed design and the skills to produce it are needed.
• Installation of an automation central control panel will be required.
• Impossibility to install a wired system in an already finished home.
• Home installation must be carried out by qualified personnel.

It can be concluded that wired automation of home processes is a good option only if the house or apartment is under construction or repair. It will also take time and money – both to develop a design and to order services of professional installers. Self-installing without knowledge of the electrics is not recommended, since in this case there is no guarantee that the structure be fire-proof.
