Concealed Security & Smart Home Pre-Wiring

Choose 4, 6 or 8 cameras to see where they go and which blind spots they close. Even if you only buy 4 cameras today, lay conduit for all 8 positions.

• Use IP / PoE cameras: one pure-copper Cat6 cable carries power and video, up to 90 m (295 ft) — avoid cheap copper-clad (CCA) cable.
• Conduit: 3/4 in (20 mm) heavy-gauge PVC per camera branch, 1–1¼ in trunk to the cabinet; use sweeping bends (never sharp elbows), a draw-box at least every 15 m or after two bends, and leave a nylon pull-rope in every pipe.
• Mount height 9–10 ft (2.7–3 m) — out of reach but still readable faces. Put a 4 in × 4 in flush box at each camera spot, with a drip loop and silicone-sealed entry.
• Keep Cat6 ≥ 12 in away from 230 V power conduits (cross at right angles) to avoid interference.
• Spare conduits: add one extra 1 in conduit from the cabinet to the roof (future Wi-Fi access point / solar monitoring).

• Place it in a central, hidden, dry room (store, under-stair, study) — not in the kitchen, near a wash-room wall or on an outer wall that gets sun.
• Recess a lockable, ventilated wall cabinet (about 18 × 18 × 9 in for 8 cameras) at 4–5 ft above the floor, with ≥ 2 ft clear in front.
• Dedicated power: two sockets on their own MCB, UPS space (load-shedding!), proper earthing, and one Cat6 to the router and one to the gate-intercom.
• Run all camera conduits into the cabinet via a 1¼ in trunk from the ceiling void or a vertical riser; label each end with the camera number before plastering.

• At the pedestrian gate pillar at 4.5 ft (1.4 m): a 4 × 4 in recessed box, 3/4 in conduit with Cat6 (PoE doorbell — more reliable than Wi-Fi at a gate) back to the cabinet.
• Add a second 2-core 1.5 mm² cable in the same sleeve for an electric door strike / gate release, and a 2-core cable for an indoor chime.
• Seal the box against rain — pillars are wet in monsoon; fit the unit under a small canopy or hood.

• Cast two sleeves under the driveway at the gate before the concrete / paving: 2 in PVC pipes, 18–24 in deep, concrete-encased — one for 230 V power, one for control. Add a spare.
• Power: 3-core 1.5 mm² copper (2.5 mm² if the run is > 25 m) from the main DB on a dedicated 10 A MCB with 30 mA RCD, and a separate earth.
• Control: 4-core shielded cable for photo-eye sensors, 2-core for the flashing lamp, 2-core for the keypad/intercom, 2-core for a battery-backup/solar input — in the separate conduit.
• Motor base: a 18 × 12 × 12 in concrete plinth with anchor bolts at the opening side, a draw-box beside it, and a clear straight line for the rack/track.
• Never share the gate motor circuit with sockets or lights. Plan a manual-release access for load-shedding and battery backup.
