It’s a brick/cement house with thick walls. To do permanent wired connection I’d have to scrape and dig holes in the walls throughout. It will cost a lot to do that + plastering/paint costs later for just a port.

It’s something I can only think of when house wide renovation is taking place.

The safety stuff is absolutely true but I have a thick brick cement wall house. To get the wires in-walled you’d have to dig holes and scrape into the walls. It takes a lot of money & time.
