21:00 personally, if I already have it (and in bulk like you have there) I'd do the 6a for everything but any cameras, and 5e for the cameras. Infact, thats what I'm planning to do in my house.

You never know where you're gonna move your desk or entertainment center or whatever to in the future, never know if you'll drop a nas somewhere that isn't a server closet. I'd like to have drops in each wall, and rule of thumb (as I'm sure you guys know) if you pull one pull two, you may need it later (especially since you're not doing conduit).

CAT6

Very much as I chose with my house while re-cabling it, CAT6 is the better choice imo, adds more time before you would need/want to update the cables in the future

Note: There is a reason why in German DIN requires data cables be run inside conduit. If standards end up changing you still can replace the affected wires.

I unfortunately would do Cat6a. Seeing speeds increase every few years when dialup was once amazing to have a 56k modem then DSL and now fiber. It was not long ago this channel talked about its 10Gb connection. I would recommend getting thin fabric gloves when working with cat6a. If your index finger starts hurting the rubber money finger tip condom thing under the glove helps if you don't want the cat6a callus.

6a cables now, no question. Network infrastructure is always growing, and if the tech house's 5e cables need to be upgraded in the future to accommodate that, you and/or Guy will end up shelling out for the 6a anyway IN ADDITION to having to destroy and replace the drywall a second time. The extra present-day cost and effort is annoying, but it will spare you a huge headache in the future.

Meanwhile every network install here in Germany is done completely in CAT7 with CAT6a sockets.

Cat5e? What is this? 2001? We are not talking about the last 5ft of ethernet cable that connects your pc to the wall and can be replaced easily if it's not good, we are talking about dozens or hundreds of ft running inside your walls, next to other cables, sending lots of data probably from your router to access points or 4K streaming devices. You can't be seriously talking about using 25 year old cables to a tech house! I would use a shielded cat7.

if you call it the 'Tech House' and it's not running the best tech, then what's even the point

I just do 6a everywhere. Price difference is negligible in the grand scheme of deployment you're doing and any slight inconvenience of working with it today is massively outweighed by inconvenience of even a small chance of redoing it in the future.

Personally, I'd have dragged in multiple runs to each location and terminated them with sockets.

Взять в аренду аппарат и сварить оптику надежнее, чем потеря линка из-за рассохшегося пластика или по другой причине, сдвинулся коннектор в разъеме например.

Silly to hear this discussion. In germany CAT7 is the default since years, and some home owners already choosing CAT8.

Flexible Tubes / conduit , Keystones, Patchpanel and network cabinet.
Shieldeding requires proper grounding of the patch panel (although a rackmountable switch could be sufficient in your case). The fire protection class of the cabling should also be considered.

6 is the only option once you got the walls down.

Not a big house? My house is about as big as that double garage.

Cat 6a. I'm doing wiring in my house all to a central point and I'm running cat6a. With work from home, I don't want to later on find out I need to move my office to an area that had cat 5e when I have Telus fibre.

I wonder how safe going around the framing truly is despite the asbestos being removed now. Might it have been good to still wear respirators/filters?

They haven't discussed if the cable should be full copper.
