BYOM — Bring Your Own Meeting
Bring Your Own Meeting

BYOM (Bring Your Own Meeting) describes a room configuration where the room's professional AV infrastructure — PTZ camera, ceiling microphone array, loudspeakers, and display — can be connected to a user's personal laptop for use with any video conferencing platform (Teams, Zoom, Webex, Google Meet, or any other). Unlike a dedicated MTR (Microsoft Teams Room) system, there is no fixed codec; the laptop is the codec. Unlike a basic BYOD room with a simple HDMI cable, BYOM provides professional audio and video rather than a laptop's built-in camera and microphone.
Why BYOM
The problem BYOM solves: organizations that standardize on one UC platform (e.g., Teams MTR) often host meetings with external guests on different platforms (Zoom, Webex). A Teams MTR room cannot natively join a Zoom call. A BYOM room allows the user's laptop to join any platform while using the room's professional AV hardware.
BYOM vs. MTR:
| Factor | MTR / Dedicated Codec | BYOM |
|---|---|---|
| Platforms supported | One (Teams, Zoom, or Webex native) | Any (platform runs on user's laptop) |
| AV hardware quality | Professional (integrated) | Professional (via USB/HDMI connection) |
| User experience | One-touch join | Requires laptop connection and source selection |
| IT management | Centrally managed appliance | Managed via laptop + room control system |
| Cost | Higher (dedicated compute + licenses) | Lower (no dedicated compute) |
BYOM Technical Implementation
USB Audio and Video (Primary Method)
The most common BYOM implementation connects the room's camera and audio device to the user's laptop via USB. The laptop recognizes them as UVC (USB Video Class) and UAC (USB Audio Class) devices — the same way any webcam or USB audio interface works. No driver installation is required on modern operating systems.
Components typically in a BYOM room:
- Camera: PTZ camera with USB 3.0 output (Sony, Logitech, Aver, Huddly) connected to a USB table box or hub at the table
- Audio: DSP (Q-SYS, Biamp, Shure IntelliMix) with USB audio interface output; the DSP handles echo cancellation, mic mixing, and speaker routing — the laptop sees a single clean audio device
- USB table connectivity: USB-C or USB-A at the table surface, connected via active USB 3.0 extender to the equipment rack
Platforms like Crestron AirMedia, Mersive Solstice, Barco ClickShare, and Extron ShareLink add content sharing over wireless/wired to a BYOM room.
Extenders for USB over Distance
USB 3.0 is rated for 3 m (passive) to 5 m. For rooms where the camera, DSP USB interface, and AV rack are more than 5 m from the user's table connection point, an active USB extender is required:
- Crestron USB-EXT-3: USB 3.0 over Cat6A, up to 30 m
- Icron USB 3-2-1: USB 3.0 over Cat6A, up to 100 m
- Valens USB 3.0: USB 3.0 over HDBaseT infrastructure
AV Control System Integration
In a managed BYOM room, the control system detects when a laptop connects (via USB device detection or HPD on HDMI) and automatically routes sources, powers the display, and selects the correct preset. The touchpanel shows "Laptop Connected" and offers one-touch BYOM mode. When the user disconnects, the room shuts down or returns to standby.
Crestron and Q-SYS both offer dedicated BYOM control programming guides. Key control logic:
- Detect USB device connect (control system USB ports that can signal device presence)
- Route camera USB and audio USB to the table outlet
- Power on display, set to laptop HDMI input
- Recall camera home preset
- Notify occupant that room is ready
Common Pitfalls
-
Laptop not recognizing BYOM camera and audio after USB connection. USB device enumeration may fail if too many USB devices are on one controller, or if the extender does not support USB 3.0 SuperSpeed. Fix: verify the USB extender is USB 3.0 compatible (not 2.0); ensure the camera and audio device are on separate USB paths if possible; test with a direct short USB cable to confirm the devices work before investigating the extender.
-
BYOM USB audio creating echo because laptop's AEC is fighting the DSP's AEC. The laptop sends its platform AEC output to the room speaker; the DSP also has AEC running on the ceiling microphones. Two AEC systems in series create artifacts and may completely suppress speech. Fix: ensure only one AEC stage is active — either disable the platform's noise suppression/AEC (not always possible) and rely on the DSP, or configure the DSP to provide a clean mic feed with AEC already applied and no AEC in the platform.
-
Laptop audio set to built-in mic/speakers instead of the BYOM USB device. The user connects the USB cable but the laptop defaults to its built-in audio; the room camera works (visible in the video conference) but audio is from the laptop speakers. Fix: train users to select the correct audio device in the platform's settings; consider automating this with a BYOM control guide or laptop management policy that sets default audio device on USB connect.
-
USB cable run too long without an active extender. A passive USB cable longer than 5 m causes intermittent camera disconnects and audio dropouts, particularly when the USB hub or table box is at the far end of the run. Fix: never run passive USB over more than 3 m; use a powered active extender for any run over 5 m.
