After several years of development, smart home market is already booming, and more and more people are beginning to embrace convenient life that smart homes provide. With development of smart home as a hidden home decoration project and connecting nerve of smart home, wiring of low current lines is especially important. If a weak current line is not suitable at initial stage, no matter how expensive a smart home is, it will not work! So, how do we connect wires to adapt to smart home decoration?
1. Low-voltage wiring in a home is designed to share resources such as Internet and cable TV, and there should be enough interfaces in every room.
Frequency division devices for Internet and cable TV connections typically have one input and four outputs. If it's a two-bedroom, one-living room apartment, you can leave network and TV ports in living room, master bedroom, and second. bedroom, and leave TV ports in dining room. If there are more rooms, you can reserve them; you can also run wires first and place them in a low current junction box, and you can change plugs leading to each room when needed. Audio and video are different. Although they can also be separated by frequency division, in principle, only one terminal can output a signal at a time at home. I do not consider it necessary to leave interfaces in every room.
2. In order to meet requirements of sharing and interconnection for low current wiring, it is necessary to use frequency separation or switching equipment.
The switching equipment of internal and external network of network usually uses an optical modem and then connects to router. If family area is large, you can choose two routers and connect them either wired or wirelessly. Today, mother-son router is more popular on market. However, for families with high network requirements, bandwidth loss of sub-router is serious, so it must be taken into account at beginning of wiring design.
3. For low current lines, star wiring should be used, extending from switching and frequency equipment to each port.
In terms of simple wiring design and convenient maintenance, it is better to place all kinds of equipment in one place. At present, new houses usually have low current junction boxes at door, and connectors for various lines are reserved in junction box, some do not have reserved jacks, but lines unfold in box and then lead into room. It doesn't matter, we cut off line in box, connect one end of house to IN jack of switching frequency division device, and other end to OUT jack, and continue to use it. We can modify low current junction box ourselves and install switching and frequency equipment. Please note that most of equipment needs electricity, and sockets must be left in low current junction box. The main functions of low-current distribution boxes sold on market are not very good, mainly for network. Although there is one input and four output interfaces, it is just a distribution frame that cannot realize intercom and multiple computers online. at thatthe same time and relatively expensive. It is better to do it yourself.
4. The choice of network cable is very important, do not try to buy cheap fakes.
More than 70% of real network failures are caused by network cables. Incorrect selection of network cables and inappropriate interfaces will seriously affect normal operation of network. Slow network speed is not necessarily a bandwidth issue, but can also be due to use of fake network cables. Most smart homes require a network connection, and network speed is slow, so experience. Fake network cables are very different from normal network cables in terms of identification, flexibility, fire resistance, etc., but easiest way to tell a real network cable from a fake one is to look at price. Except for promotional factors, a genuine category 5 or super category 5 cable trunk worth more than 350 yuan is valued at about 200 yuan, so you should be careful.
