A modern video conference room needs four sets of runs: power and network at the display wall for the TV and video bar, network (often PoE) to the table for a touch controller, video sharing at the table (HDMI or USB-C to the display wall), and mic cables if you add table or ceiling mics. Plan at least one 2-in conduit or a floor box from the table to the display wall, and keep every cable run within its length limit or use active or extender cables.

Appliance bars (Teams Rooms, Zoom Rooms or Meet on the device) put most connections at the display wall. PC-based rooms add a compute box behind the TV or in a credenza with USB runs to the camera and table.
What to run where
| Location | Run | Notes |
|---|---|---|
| Behind display | 2 duplex power outlets | TV, video bar, compute |
| Behind display | 2 Cat6 drops | Video bar and display or compute |
| Behind display | Conduit to table | 1.5-2 in for future cables |
| Table / floor box | 1 Cat6 drop (PoE) | Touch controller like Logitech Tap IP |
| Table / floor box | HDMI and/or USB-C | Laptop sharing or BYOD |
| Table / floor box | Power and USB-C charging | Laptops |
| Table or ceiling | Mic cables | Expansion mics or ceiling mic |
| Door | Cat6 (PoE) | Booking panel |
See electrical requirements and table power and connectivity.
Cable length limits
| Cable | Passive limit (approx.) | For longer runs |
|---|---|---|
| HDMI (4K) | 15-25 ft (4.5-7.5 m) | Active optical HDMI or HDBaseT extender |
| USB 3 | 10 ft (3 m) | Active optical USB like Logitech Strong USB (10/25/45 m) |
| USB-C with video (BYOD) | 6 ft (2 m) | Active cable like Logitech Active USB Cable (5 m) |
| Ethernet (Cat6) | 328 ft (100 m) | Switch in between |
For brand-specific runs, Logitech's Rally Camera Extension Kit carries the Rally Camera up to 100 m over one category cable, and the Rally Mic Pod Extension Cable adds 10 m to mic runs. See Logitech wiring diagrams.
Conduit and pathways
- Floor boxes under the table are cleanest for new builds; coordinate with the electrician and flooring.
- Poke-throughs or raised floor in existing offices.
- Wall conduit behind the display with a recessed box so the TV mounts flat.
- Plenum-rated cable where runs pass through air-handling ceiling spaces. Check local code.
- Leave a pull string in every conduit.
Network requirements
- Put room devices on a managed network, often their own VLAN.
- Provide PoE (802.3af is enough for most controllers and panels, such as Logitech Tap IP and Neat Pad; cameras and some bars need PoE+ or PoE++; check the device spec).
- Open the platform's required ports. See Teams Rooms network requirements and Zoom Rooms requirements.
Labeling and cable management
- Label both ends of every cable.
- Use a cable tray or management under the table.
- Mount compute and power bricks behind the display or in a credenza, not on the floor. See Logitech Compute Mount.
