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 have only installed the network cable. Satellite TV is simply streamed over the network via a TV server. Additional cables are unnecessary. Everyone has to decide for themselves. I chose to forgo them.

@ruppsn: I currently have IPTV running via a TVHeadend server and use Raspberry Pis behind the TVs for this. Everything works perfectly: EPG, channel change speed, quality, recordings. It all works. A coworker has a similar setup with a SAT>IP server.

I need to ask him what exactly he’s using.

Satellite cable is high quality and using it is a no-brainer. When the Raspberry Pi acts up, you need the tech-savvy parent while Mom is complaining. SatIP is a nice solution when it works. However, it requires an external receiver since very few TVs have one built-in. I would actually like to have SatIP, but it hasn’t really caught on yet, and you don’t only hear good things about it. Unfortunately, it also seems that SatIP LNBs are no longer available, which would have allowed you to skip the separate box.

Well, everyone has to decide for themselves... I don’t see anything old-fashioned about a satellite cable installation. On the other hand, I always have a stable picture and don’t use up bandwidth just to watch TV once in a while.

And the costs are really low... for less than 500 euros you can get an outlet with a cable in the living areas and the dish on the roof.

Shouldn’t that be solved with a separate subnet and/or IPv6/QoS?

How does the bandwidth of coax compare to CAT7?

I have no idea if that’s just your style, but this constant dismissal of other opinions and the arrogance behind it are starting to get annoying.

You wouldn’t like it either if someone called your opinions nonsense or KNX a toy… so does it really have to be like this all the time?

It only unnecessarily distracts from the content of your posts… that would be a shame, don’t you agree?

I have noticed this arrogance quite often as well...

I completely agree with the "TV over IP" discussion. However, we still installed satellite cable... simply to keep the house more "marketable."
