ᐅ General: Network, TV cable, bus system

Hello dear community,

we are planning to buy a house, preferably an energy-efficient House 55. To be clear, we are still searching and currently have nothing fixed.

However, I am already thinking a lot about topics such as the home network, home bus system, and TV wiring. I have searched a lot online, but many questions remain. I now have some questions and hope you can help me with your experience:

Home Network
  • Which cables should I install, considering future-proofing? Cat 6 or Cat 7?
  • How does it work with the cables? They are bought, for example, on a 100 or 200 meter (328 or 656 feet) roll. Do connectors need to be attached afterward?
  • How are the cables connected to flush-mounted sockets?
  • The central point should be the basement. Everything should come together here. Do you use a patch panel (which I have never heard of before) or a router with switches? Internet will be provided by a cable provider. Would the installation then be as follows? Wall socket in the basement --> cable provider’s modem --> router --> patch panel --> flush-mounted sockets?
  • How are the network cables actually routed? One cable from the patch panel to each flush-mounted socket? The sockets should each have 2 ports. Or do you have to run 2 cables per socket? IMPORTANT: At least gigabit is required everywhere, preferably 10 Gb! If you assume one cable per port, that will result in a lot of cables.
Home Bus System
  • Our house should also be future-proof. I keep reading about KNX/EIB bus systems for homes. Can you recommend them? I am thinking, for example, of programming lights and monitoring and controlling the heating and ventilation system.
  • What do you think of the company GIRA (KNX system, sockets, etc.)?
  • For security reasons, I do not want the home bus system to be connected to the Internet. I do not need to control the heating via the Internet, etc. Is something like this possible (a private home network)?
TV Wiring
  • TV wiring is actually related to my questions about network installation. What kind of cables are used here?
  • Is one cable installed per socket?
  • How is this implemented if you have a satellite dish with one LNB? Can the signal be distributed throughout the house? Can everyone watch what they want? Or is additional equipment needed?
Sorry for the many questions, but I need to close my knowledge gaps step by step.

Thank you very much for your help.

I am simply thinking very far into the future. Whether and when I will ever need the cables is unknown. But it's better to have them than to need them later. I’m very into movies. I’m installing a VPL-VW550 ES projector with a suitable screen. Along with that, I have DTS-X / Atmos (7.2.4) with 11 Nubert speakers. Between the projector and AV rack, there are HDMI, DisplayPort, and fiber optic cables. This setup should prepare me even for 8k+ content. Speaker cables everywhere are 2x 4mm (0.16 inch) copper. Additionally, I have 2x 2.5mm (0.10 inch) copper cables running from the utility room to all bathrooms, hallway, kitchen, and bedrooms. Each of those will have a Canton InCeiling 865 DT speaker. These serve for announcements and background music. That way, there is a “wellness feeling” even in the guest bathroom. Or for example, when there’s mail in the mailbox, a friendly “You have mail” message plays.

Regards, Steffen

But before your CAT7 cable reaches its performance limit (or before you even have an interface with Cat7), the HDMI specification will likely change, meaning you will need a new cable.

Therefore, use an empty conduit, preferably one size larger than currently needed, and make sure the radius at the corners is sufficiently large. This way, you keep many options open for the future!

Recently, I mentioned the Diginet law here, which requires fiber optic installation in new development areas. What does your city administration say about this?

Man, not bad Steffen. So you’re probably active in the hi-fi forum too, right?

I can’t make sense of all those abbreviations right now, I’ll have to google them at home. How does the “you’ve got mail” thing work?

My wife is going to kill me if I tell her… She says I’m already on too many forums, it only makes everything more expensive.

I had read about it and immediately became interested. However, the development of our building area started in 2013/2014, and back then, this was not yet the case, right?
