Smart Home Wiring and Automation for London Victorian Terraces: Structured Cabling and Systems

THE FOUNDATION OF A SMART HOME IN A LONDON VICTORIAN TERRACE IS A STRUCTURED CABLING SYSTEM — A STAR-TOPOLOGY NETWORK OF DATA CABLES RUNNING FROM A CENTRAL DISTRIBUTION POINT (PATCH PANEL + NETWORK SWITCH) TO EVERY ROOM AND DEVICE LOCATION IN THE PROPERTY. UNLIKE AD HOC WIFI EXTENSION WITH POWERLINE ADAPTERS OR MESH NODES, STRUCTURED CABLING PROVIDES: RELIABLE, LOW-LATENCY, HIGH-BANDWIDTH WIRED CONNECTIVITY TO EVERY ROOM (IMPORTANT FOR STREAMING, VIDEO CONFERENCING, AND SMART HOME DEVICES). A STABLE BACKBONE FOR WIFI ACCESS POINTS (WIRED WIFI ACCESS POINTS — UBIQUITI UNIFI UAP-AC-LR OR UAP-AC-PRO — ACHIEVE SIGNIFICANTLY BETTER PERFORMANCE THAN STANDALONE WIFI ROUTERS OR POWERLINE ADAPTERS). FUTURE-PROOF INFRASTRUCTURE THAT DOES NOT DEPEND ON RADIO FREQUENCIES (WIFI) FOR RELIABILITY.

RISCO GROUP LIGHTSYS 2 (THE PREFERRED CHOICE FOR INSURANCE-COMPLIANT NSI GOLD GRADE 3 ALARM SYSTEM IN HIGHER-VALUE LONDON TERRACE RENOVATIONS).

PLANNING THE SMART HOME WIRING OF A LONDON VICTORIAN TERRACE RENOVATION REQUIRES A SYSTEMATIC ROOM-BY-ROOM SCHEDULE OF CABLE REQUIREMENTS, COMBINED WITH AN UNDERSTANDING OF THE INSTALLATION SEQUENCE (CABLE MUST BE PULLED BEFORE PLASTERBOARD IS FIXED AND WALLS ARE PLASTERED).

CONCURRENCY WITH FIRST-FIX ELECTRICAL AND PLUMBING: SMART HOME DATA CABLING (CAT6, SPEAKER CABLE, HDMI) SHOULD BE PULLED AT THE SAME STAGE AS THE FIRST-FIX ELECTRICAL AND PLUMBING ROUGH-IN — WHEN WALLS ARE OPEN, JOISTS ARE EXPOSED, AND CABLE RUNS CAN BE DRILLED THROUGH STRUCTURAL ELEMENTS. MISSED FIRST-FIX CABLE RUNS: IF A CAT6 OR SPEAKER CABLE RUNS IS NOT PULLED AT FIRST-FIX, RETROFITTING IT IN A COMPLETED PLASTERBOARD OR PLASTER WALL REQUIRES EITHER: CHASING (CUTTING A SLOT IN THE PLASTER FOR THE CABLE — DISRUPTIVE AND ADDS REDECORATING COST). SURFACE TRUNKING (PLASTIC CONDUIT ON THE WALL SURFACE — VISIBLE, NOT DESIRABLE IN A HIGH-SPECIFICATION LONDON TERRACE RENOVATION).

MINIMUM CABLE SCHEDULE FOR A 3-BED LONDON VICTORIAN TERRACE RENOVATION (ROOM-BY-ROOM): GROUND FLOOR RECEPTION (2 ROOMS): 2 X CAT6 TO EACH ROOM (DATA POINTS FOR WIRED ETHERNET + WIFI AP EACH ROOM); 2 X SPEAKER CABLE TO CEILING; 1 X HDMI (TV ROOM).
