When a meeting room disappoints, the equipment is rarely the problem. Something was missed in the plan. These seven items cost little to get right at the design stage and a great deal to fix after the fit-out.
1. Acoustics and microphone pickup
Sound is usually the first complaint: speech that is hard to follow, echo, or a remote speaker whose volume keeps changing. Intelligibility depends on background noise and reverberation, including air-conditioning outlets, projector fans and corridor noise. Classroom acoustics standards commonly allow no more than about 35 dBA of background noise and about 0.6 seconds of reverberation, a reasonable starting point for a meeting room.
Choose microphones to suit the seating. Table microphones sit close to the talker and pick up consistently. Ceiling array microphones keep the table clear but are further from the talker and more sensitive to noise and reverberation, so they depend on a DSP with beamforming and acoustic echo cancellation (AEC). Tune loudspeaker and microphone positions and gains together, or the remote voice is picked up again and returns to the far end as echo. Decide absorbing materials, loudspeaker positions and microphone type before the fit-out, because correcting them afterwards is expensive.
2. Camera framing and lighting
Mount the camera centrally above or below the display, with the lens near eye level, or the picture shows heads and chins. A single wide-angle lens has a limited field of view, and the seats at each end of a long table are often cropped, so you may need several cameras or automatic framing, depending on the product. Give the camera presets, such as the whole room, the speaker and the whiteboard, so one button changes the view.
Lighting matters as much. Illuminance on faces of roughly 300 to 500 lux, from the front and with a consistent colour temperature, is a common recommendation. Anyone sitting in front of a window becomes a silhouette, so blinds belong in the plan, and reflections from glass partitions and whiteboards should be checked when the camera is placed.
3. Display size and viewing distance
A common rule of thumb puts the farthest seat at about six times the picture height for content where detail matters, and up to eight times for ordinary presentations and video. The nearest seat should be no closer than about twice the height. A 65-inch 16:9 display is about 81 cm high, so the farthest seat should be within roughly 5 to 6.5 metres.
If the room is longer than that, use a larger display, an LED wall or an extra screen part-way down the room. Higher resolution does not fix distance on its own: 4K shows more detail only if the source, the extender and the cables all support it.
4. Wireless presentation and bring-your-own-device
Staff and visitors bring Windows, macOS, iOS and Android devices, and each supports wireless casting differently, through AirPlay, Google Cast or Miracast for example. Decide which the room must support, then choose equipment to match.
Wireless presentation tends to fail when the network is congested or the guest network is restricted, so keep a wired HDMI or USB-C input at the table or on the wall. A single USB-C cable can carry video, a USB camera and microphone, and charging, if the laptop’s port and the room equipment support it.
5. Cable paths and spare conduit
Leave room in wall and floor conduit for cables to be replaced later. A third spare is usual practice; the real figure depends on the site and regulations. Keep signal cables apart from mains power cables, and cross them at right angles when you must.
Cable length decides the conduit. Passive HDMI cable at 4K suits only a few metres, and longer runs need HDBaseT (about 100 m over Cat6A) or fibre, so choose the extension method first and size the conduit afterwards. At handover, leave a cable and outlet schedule, cable labels and as-built drawings, so that whoever services the room can find the cable.
6. A control interface that stays simple
A good control interface lets people start a meeting with one action, without knowing how the signals travel. Keep only power, source selection, volume, mute and camera presets, and use names that people recognise rather than engineering labels such as “HDMI 2”. Use the same interface in every room, so nobody has to relearn it.
Automation reduces effort, for example switching source when a signal appears and powering down when the meeting ends, but there must always be a manual override. If the control system fails, the display remote and the wired inputs should still work. Confirm that fallback at design time.
7. Network and security coordination with IT
Cameras, DSPs, wireless presentation units, control processors and meeting platform endpoints are all network devices, and each needs an IP address, a VLAN and firewall rules. Before go-live, agree with IT whether addresses are static or reserved through DHCP, whether 802.1X authentication and certificates are required, how time is synchronised, what the meeting platform needs in bandwidth and ports, and that default passwords and unused services are switched off.
Write down who looks after the room afterwards, including who schedules firmware updates and who takes over when a device misbehaves. Without that, the room runs with no one in charge of it.
