Home automation is a body of work encompassing data, audio visual and electrical cabling. The image below is of the cabling in a home in London which controls everything from the lighting to the security system. It also includes 4K video distribution via fibre optic cabling to every room in this 6 bedroom home.
Data is distributed primarily via Cat6a cabling OM2 fibre cabling. The use of various colour cables allows each cable to be more easily traced from source to destination.
The garage will house a data cabinet which will be home to the 16 camera CCTV recording system, LAN network equipment, control units for lighting, locks, blinds, etc, and internet distribution hardware.
