Meeting Room Cabling and Pathway Design: From Floor Box to Camera Bar
Meeting room cabling is invisible when designed well and obvious when designed poorly. Cables snaking across floors. HDMI cables that don’t reach. Power outlets in wrong places. Camera bar mounted but no Ethernet pulled to it. The construction phase is the only practical time to get this right — retrofit cabling in a finished room is 5-10x the cost of building it in. This piece walks through meeting room cabling and pathway design for Saudi office fit-outs.
The four cable runs that matter most
Every meeting room needs four primary cable runs designed and installed during construction:
1. Display cable run. From the equipment rack location to the display location (wall or ceiling). Carries video (HDMI or SDI), audio (if not via display), control (RS-232 or IP for control of display).
2. Camera + audio cable run. From rack to camera/mic location. USB extension for USB cameras (limited to ~5m unless powered extender), Ethernet for IP cameras and PoE microphones, sometimes additional audio cabling.
3. Table connectivity run. From the floor box at table location to the rack. Provides power, network, video input (HDMI/USB-C), audio input, sometimes microphone audio.
4. Network and power. Multiple Ethernet runs for the various devices, dedicated electrical circuits for AV equipment, isolated grounding for sensitive audio.
Floor box placement
Floor boxes at meeting room tables are the most-used and most-difficult-to-relocate cabling element. Get them right at construction phase:
- Position: typically under the meeting table, 1.5m from each end. For long boardroom tables, multiple floor boxes spaced evenly.
- Capacity: minimum 4 power outlets, 2 Ethernet, 1 HDMI input pass-through, 1 USB-C input. Modern boxes also include USB-A pass-through.
- Power: dedicated AV circuit (separate from general power) reduces noise. UPS-backed where critical.
- Cable management: sufficient slack inside the box for cable replacement, brush dust seal to prevent debris.
Ceiling-mounted devices
Cameras, microphones, and speakers mounted in ceiling need pathway design:
Pathway: conduit or cable tray running through ceiling void from rack to device location. Typical: 32-50mm conduit for camera + microphone bundle.
Cable types: Ethernet (Cat6A) for IP cameras and PoE microphones, balanced audio for ceiling speakers, HDMI for ceiling-mounted projectors (rare in modern designs).
Mounting boxes: recessed mounting boxes integrated into ceiling tile pattern. Pre-installed during construction.
Power: usually PoE (no separate power needed for cameras and microphones if PoE switch supports them).
Wall-mounted display cabling
For wall-mounted displays:
Mounting plate: structural mount sized for the display weight, anchored to studs or solid wall.
Cable concealment: recessed in-wall conduit hiding all cables. Conduit terminates at recessed wall plate behind display.
Cables: HDMI (or HDMI-over-HDBaseT for runs >15m), control (RS-232 or IP), power.
Cable length: typically need 3-4m of slack at the rack end to allow display servicing without disconnecting.
HDMI vs USB-C vs network video
Three approaches to getting video to the display:
HDMI direct. Simple but distance-limited. Standard HDMI: 5-7m without active components. Active HDMI cables or fiber HDMI: up to 50m.
HDMI-over-HDBaseT. Uses Cat6/Cat6A cabling for HDMI extension up to 100m. Common in mid-large rooms. Requires transmitter at source and receiver at display.
AV-over-IP. Network-based video distribution. Modern approach for multi-display deployments and centralised AV equipment. Requires network capacity (10 Gbps for 4K). Common in larger deployments and customer-facing spaces.
AV-over-IP design considerations
For larger deployments and design-flexible installations, AV-over-IP is increasingly the standard. Equipment vendors (Crestron, Extron, AMX, Atlona, ZeeVee) provide encoder/decoder pairs that distribute video across standard network infrastructure.
Network requirements: dedicated VLAN for AV traffic, multicast routing if multi-display sources, sufficient bandwidth (4K typically 10 Gbps per stream), low latency switches, IGMP snooping configured.
Future-proofing for higher resolutions
Cabling installed today should handle: 4K 60Hz HDR (current standard for premium spaces), 8K 60Hz (emerging for high-end deployments), longer runs without quality loss, future protocol changes.
Practical implications: use Cat6A for all data runs, use fiber for backbone runs >100m, install pathway oversize for future cable additions, document everything for future modifications.
Contractor coordination during fit-out
Meeting room cabling involves multiple contractors: low-current installer, electrical contractor, AV integrator, fit-out contractor, network installer. Coordination patterns:
Sequencing: low-current pathway first (during ceiling work), electrical second, network third, AV equipment last.
Documentation: AV/IT requirements detailed in fit-out drawings, signed off by all contractors before construction starts.
Inspection: AV integrator inspects pathway and cable runs before ceiling closes — once ceiling is in, retrofitting cables is expensive.
As-built drawings: contractor delivers documented record of every cable run with labels, source, destination, type, length.
Cost benchmarks
Meeting room cabling and pathway, indicative costs per room:
- Huddle space: SAR 5,000-12,000
- Medium meeting room: SAR 10,000-25,000
- Large meeting room: SAR 20,000-50,000
- Boardroom: SAR 35,000-100,000+
Costs are dramatically lower if integrated with broader low-current scope of fit-out (vs separate scope).
