There are many types of wires that can be installed inside a wall, for example, Internet, phone, and cable wires, as well as speaker and alarm wires, which depend on the application. There are also different video formats that you may require if you are going to hang a flat panel TV on the wall, and for these, and many other necessities, here we give you a list of the different wires there are:
This one is used mainly for TV, satellite, and cable modems, and can also be used to move video between rooms, let’s say, to share a Tivo or cable/satellite box output on two TVs. You can adapt 3 coaxial wires together to work as component or composite wires. Not very often, it is also used for security cameras and digital audio.
There are 2 types of coaxial cable: RG-59 and RG-6. This last one is the only one that you should be using, since everything is moving towards digital, and it is high quality.
2.Category 3 wire
This is used as phone wire. Each pair of twisted wires handles one phone line. The typical kind has two pairs of wire for two phone lines; however, the plugs can handle three pairs for three lines. Phone wire can be black, red, green, and yellow, or orange stripe, blue, blue stripe, and orange.
3.Category 5, 5e, 6, and 7 wire
These are used for Internet connections and network cabling. Your cable or DSL modem will output this network wire, where category 5 is the lowest quality and category 7 is the top. All of them look the same, but the best ones have extra twists and better shielding that allow for the transmission of more data. These can also be used for other data applications like remote volume control knobs, security cameras, and infrared distribution.
This one’s thicker than the Cat 3 cable and is used to wire security systems, that is, alarm panels, window/door sensors, motion detectors, and sirens.
This is needed for in wall/in ceiling speakers. It comes in 2 conductor (red and black for + and -) or 4 conductor (red, black, white, and green, for left+, left-, right+ and right-).
It is used for digital audio, however in the future it may be used for other applications like Internet and TV.
This is used for audio and video. It is a very popular and inexpensive format although the video quality is the worst available and can’t handle HDTV signals.
This popular video format is being replaced with DVI and HDMI. It is actually two coaxial cables in one, with two signal cables (Y and C) and two grounds.
This video format is better than S-Video even though it is less common and is also being replaced by DVI and HDMI.
10.VGA (Video Graphics Array)
This is the old computer monitor video format that can be found in old flat panel TVs.
11.DVI (Digital Visual Interface)
This is the video format used now in most flat panel computer monitors. It comes in three formats: DVI-D (Digital), DVI-A (Analog), and DVI-I (Integrated).
12.HDMI (High-Definition Multimedia Interface)
This is the latest standard for high-end flat panel TVs.
13.UDI (Unified Display Interface)
This is trying to become the next video standard. It offers higher resolutions than HDMI.
It also offers higher resolutions than HDMI, but it is still being developed.
You need it if you have your remote in one room and your stereo components in another. The sensor must be where the remote is, and the main unit where the stereo components are.
