Smart home: how to lay cables for an automation system?
If a Smart home installation fails during operation, most often the problem is not in the systems themselves, but in a poorly executed installation (wiring, equipotential connection, grounding, poorly selected overvoltage protection, etc.). keep in mind that every Smart home system is an electronics that Is sensitive to voltage surges. I suggest you read the articles that describe the main issues related to the implementation of any, even traditional electrical installation.
How to properly conduct wiring in the house
When building buildings, each investor starts with the Foundation. When thinking about home improvement, you need to start with the wiring. When designing a power plant, it is necessary to lay low-voltage cable wiring:
phone number,
computer,
satellite TV signals,
internal communication cables for control and execution automation systems.
More and more often, developers decide to make cabling in order to leave the choice of active automation devices to the individual requirements of the client. Electrical installation of the entire house should be performed during its construction or repair. Cables laid in the walls at this stage allow the user to connect devices that are responsible for the comfort and safety of family members.
A properly designed and executed installation is unobtrusive, practical, and inexpensive. The absence of any cable element at the beginning may have unpleasant consequences in the future. Therefore, it is recommended to always create design documentation prepared by an experienced design Bureau.
Before starting any installation work, it is important to make sure what the installation is intended for. It often happens that cables are laid in a hurry, without consulting specialists on individual installations, limiting the functions of individual systems.
Telephony and computer network in a private home
When planning the internal telephone network in a single-family house, you should think about using a twisted pair cable. This wiring will allow us to further expand the installation of a computer and telephone network in the future, then we will avoid laying additional cables.
Intercom (video). To connect, you will need a coaxial cable (for video transmission) and two pairs (for power and audio transmission). Due to the fact that it is usually buried in the ground, it must be protected from moisture penetration by microcracks in the coating.
Audio – video cables. According to information provided by some manufacturers of high-quality audio equipment, the total resistance of connecting a power amplifier to a loudspeaker should not exceed approximately 1/100 of the nominal impedance of the loudspeaker, that is, in the case of 4 Ohms, it will not exceed 40 m. ohms. It is Also clear that for a given cable length, a speaker with a higher resistance allows for a thinner cross-section of the cable.
