Why Your Dubai Conference Room Audio and Video Is Poor (And How to Fix It)

The Most Common Conference Room AV Complaints in Dubai

After installing and maintaining smart meeting rooms across Dubai, we see the same problems repeatedly. Most have simple fixes — once you diagnose the actual cause.

Problem 1: Echo and Reverb

Cause A: PC built-in microphone is active alongside conference microphone.

Fix: In Windows Sound Settings, disable the built-in PC microphone as an input device. Set only the conference room microphone (Logitech, Jabra, Poly) as the default.

Cause B: Acoustic echo in the room.

Dubai conference rooms with hard floors, glass walls, and no acoustic treatment create significant echo.

Fix: Add acoustic panels to rear wall. Move microphone closer to speakers. Add carpet or soft furniture.

Cause C: Speaker volume too high feeding back into the microphone.

Fix: Reduce speaker volume by 20% and test. Ensure directional microphone is facing participants, not speakers.

Problem 2: Choppy or Pixelated Video

Cause: Insufficient internet bandwidth or WiFi issues.

Test: Run a speed test from the conference room device. Teams/Zoom HD video requires:

• Sending: minimum 1.2 Mbps for HD (720p), 3.8 Mbps for 1080p
• Receiving: minimum 1.5 Mbps for HD

If bandwidth is fine, check:

• Is the conference room device on WiFi or Ethernet? Ethernet is always preferred.
• Is there QoS enabled for video conferencing traffic on the firewall?
• Is the conference room on a shared WiFi band with dozens of other devices?

Fix: Connect conference room PC to Ethernet. Enable QoS to prioritise video conference traffic.

Problem 3: Participants Cannot Hear the Room

Cause A: Wrong microphone selected in the meeting app.

Fix: In Teams or Zoom settings, confirm the conference room microphone (not the PC built-in) is selected as input.

Cause B: Microphone too far from participants.

Logitech MeetUp and Rally Bar have a pickup range of 4 to 6 metres. For a 10-person room, the standard single microphone does not cover the far end of the table.

Fix: Add expansion microphone pod(s). One pod per 3 to 4 metres of table.

Cause C: Microphone muted at the hardware level.

Fix: Check physical mute button on conference device. Check LED indicator — red usually means muted.

Problem 4: Camera Shows Wrong View

Cause A: Camera not set to correct preset or auto-framing disabled.

Fix: For Logitech Rally, use Logitech Sync app to configure camera presets and enable RightSight auto-framing.

Cause B: Camera too close or too far from the display.

The camera should be at approximately eye level when participants look at the screen.

Fix: Reposition camera using VESA mount or bracket.

Quick Diagnostic Checklist

Conference Room AV Fixes: Frequently Asked Questions

What's the most common cause of echo in a conference room? The PC's built-in microphone staying active alongside the dedicated conference microphone — disabling it in Windows Sound Settings and setting only the room mic as default usually fixes it immediately.

Why is video choppy or pixelated in a conference call even with good internet? Often the room device is on WiFi instead of Ethernet, or there's no QoS prioritizing video conferencing traffic on the firewall — switching to a wired connection and enabling QoS resolves most cases.

Why can't remote participants hear everyone in the room? The microphone's pickup range (typically 4 to 6 metres for standard units) doesn't cover the full table in larger rooms — adding an expansion microphone pod per 3 to 4 metres of table length fixes this.

What bandwidth does HD video conferencing actually require? A minimum of 1.2 Mbps sending and 1.5 Mbps receiving for 720p HD, rising to 3.8 Mbps sending for 1080p — worth testing directly from the room device before assuming a hardware problem.
