Making Informed Decisions Group video conferencing / collaboration is not a new subject. And many of the vendors offering group
video conferencing solutions have been in this business for more than 20 years.
And as one might expect, over the years the features, functions, and capabilities offered by group video
conferencing systems have expanded and evolved. And the requirements and expectations of
collaboration users have changed along with them.
For decades, group video was viewed as a technical curiosity understood by a relatively small society of
trained and experienced VC professionals. This has changed in recent years as video conferencing has
fallen under the auspices of the IT department, thanks in part to group video technology becoming more
IT-centric (in terms of management and the use of the enterprise IP network) and IT-friendly.
Despite video conferencing becoming a mainstream business tool, many end user organizations remain
confused about how to choose the group video conferencing systems that best address their needs.
The goal of this document is to help IT managers understand the features and functions needed to
collaboration-enable five of the most common spaces found in enterprises of all sizes:
- small (huddle) rooms
- teaming / ideation spaces
- standard meeting rooms
- executive boardrooms
- reconfigurable (and perhaps divisible) spaces.
With this information in hand, customers can make group video conferencing product decisions from a
position of knowledge.

Space: Huddle Room Definition A huddle room is a meeting room that can accommodate only a small number of attendees (usually 6 or less). Huddle rooms are best suited for informal, ad-hoc meetings.
WR estimates that there are ~ 40 million huddle rooms in the world today, most with little or no audio-visual equipment.
Requirements The requirements for a group video system for use in a typical huddle room are as follows:
Topics Description
[ ] Low Cost Due to the large number of huddle rooms within the company, low cost is critical.
[ ] Form Factor Set-top, split-system, or even conference-phone form factor are acceptable. Rack mount is not acceptable as most huddle rooms have no equipment rack.
[ ] Networking A wired Ethernet connection is a requirement, and Power over Ethernet (PoE) is a strong value-add as it simplifies cabling and system installation.
[ ] Camera Ideally a fixed, wide-angle (120+ degree FOV) camera would be utilized as this ensures that even people sitting close to the main display are captured. Alternatively an inexpensive, wide-angle PTZ (pan / tilt / zoom) camera is acceptable.
[ ] Video In / Content In
One additional HDMI input (beyond the input for the main camera) is required to allow for wired content sharing. Additional video inputs are considered nice to have.
[ ] Video Out A single HDMI video output driving the main display is all that’s required. Due to the small room size, additional outputs (e.g. for a 2nd display) are not really necessary.
[ ] Audio In / Mic Options
The microphone requirements depend on the room size and seating arrangement. However, in general, a single table mic or one or more embedded mics within the video system itself should be acceptable.
A combined mic / speaker “pod” would also be interesting as it offers both mics and speakers (and perhaps even control) in a single place.
[ ] Audio Out The main audio out is typically sent to the room display over an HDMI connection. An additional line level audio output is a nice to have – especially for larger huddle rooms. A mic / speaker pod is also an interesting option.
[ ] Audio Conferencing
The system should support audio conferencing (VoIP / SIP), and ideally should include a stand-alone dialer located on the meeting room table.
[ ] Wireless Presentation
Wireless presentation from laptops and mobile devices, while in a call and not in a call, should be supported – either by the group video system or using an additional device.
[ ] Video Conferencing
The group video system should support standards-based (SIP) video. In addition, the space should support video conferencing using apps running on a user’s notebook PC.
[ ] Control & Management
The ability to control the video conferencing system from a BYO device is recommended. For large scale deployments, centralized device management and control is required.
Additional Comments:
WR believes that most huddle rooms should be collaboration-enabled by a single, multi-function device. When evaluating huddle room system options, customers should prioritize low cost, ease of purchase, ease of installation, ease of use, and support for remote management. While strong audio and video quality are certainly important, advanced features (e.g. numerous inputs / outputs, etc.) are typically unnecessary luxury items in these spaces.

Space: Teaming / Ideation Space Definition A teaming / ideation space is a meeting place designed to foster creativity and teaming (e.g. brainstorming, problem solving, strategic thinking, whiteboarding, etc.). These spaces come in many shapes and sizes, include one or more displays, and use special software / systems to empower ideation.
Requirements The requirements for a group video system for use in a teaming / ideation space are as follows:
Topics Description
[ ] Low Cost In these spaces, low cost is less important than the feel and experience provided.
[ ] Form Factor A small footprint is important in this space. Rack mount is not acceptable.
[ ] Networking A wired Ethernet connection is a requirement, and Power over Ethernet (PoE) is a strong value-add as it simplifies cabling and system installation.
[ ] Camera
The goal is to capture all of the people in the teaming space on camera. Ideally, this would include people working at the display or walking around the room. Here are several options (the proper choice depends on the layout in use):
Option 1 – A fixed, wide-angle or panoramic camera at the front of the room. This is best suited for teaming spaces with traditional layouts (e.g. a meeting room table).
Option 2 – A 360 degree camera system (either a single system or multi-camera setup) located in the middle of the room (note – not necessary on a table as some teaming spaces will not have a meeting room table at all).
Option 3 – A custom installation involving several cameras and a speaker tracking or camera switching system. This is likely to increase cost / complexity.
[ ] Video In / Content In
At least one HDMI input (beyond the input for the main camera) is required to support wired content sharing. In addition, if the ideation content will be shared through the group video system, an additional HDMI input may be required.
[ ] Video Out Two video outputs, one for video and one for shared content, are required.
[ ] Audio In / Mic Options
The proper microphone setup depends on the layout of the space.
Option 1 – In rooms with a center table or device in the middle of the room, a single omni-directional microphone (or a tri-mic / mic pod) may be sufficient.
Option 2 – In rooms with no table, ceiling mics or wireless mics will likely be required.
In some situations, several microphones will be needed, which means the system will require multiple microphone inputs or a line level input (for use with a mic mixer).
[ ] Audio Out
The proper audio out setup depends on the room layout.
In many spaces, the audio on the HDMI video output to the display will be sufficient. In other spaces, a line level output will be needed to drive an external speaker system.
[ ] Audio Conferencing
The system should support audio conferencing (VoIP / SIP), and ideally should include a stand-alone dialer either on the table (if applicable), wall mounted, or wireless.
[ ] Wireless Presentation
Wireless presentation from laptops and mobile devices, while in a call and not in a call, should be supported – either by the group video system or using an additional device.
[ ] Video Conferencing
The group video system should support standards-based (SIP) video. In addition, the space should support video conferencing using apps running on a user’s notebook PC and/or on a meeting room PC.
[ ] Control & Management
The ability to control the video conferencing system from a BYO device is recommended, as is centralized device monitoring / management / control.

Additional Comments:
When creating teaming / ideation spaces, customers should consider the comfort of the session participants as this empowers creativity. In many cases, aesthetics, and specifically how well the technology blends into the space, will be more important than tight camera shots and perfect audio / video quality. Note that teaming / ideation rooms are NOT standard meeting rooms --- they are special spaces designed for special purposes, and should be treated as such.

Space: Standard Meeting Room Definition A “typical” meeting room with 7 – 16 seats positioned around a rectangular table and including one or two displays mounted on the front wall.
Requirements The requirements for a group video system to support a standard meeting room are as follows:
Topics Description
[ ] Low Cost While always appreciated, low cost is a nice to have in this space. Many things are more important including reliability, ease of use, manageability, etc.
[ ] Form Factor Split-system with a rack mountable base unit is the preferred form factor – especially for larger rooms. If necessary, a set-top system is a viable alternative.
[ ] Networking A wired Ethernet connection is a requirement. Wi-Fi and power over Ethernet (PoE) capabilities are not necessary.
[ ] Camera These spaces require a high performance PTZ (pan / tilt / zoom) camera. While not strictly required, a speaker tracking system is highly recommended – especially for larger rooms with long tables.
[ ] Video In / Content In
One additional HDMI input (beyond the input for the main camera) is required to allow for wired content sharing. Additional video inputs are recommended and worthy of some limited additional cost.
[ ] Video Out For most standard meeting rooms, two HDMI video outputs (to drive two displays) are required. Even if the space is too small / narrow to support two displays, support for two video outputs is recommended for obsolescence protection.
[ ] Audio In / Mic Options
For typical meeting rooms, more than one microphone will be needed.
Option 1 – Support for multiple mics directly connected to the group video system. This is an easy, cost-effective way to capture the mic audio in a standard meeting room.
Option 2 – A line level input on the group video system to be used with an external mic mixer / digital signal processor (DSP). This is a flexible, but more costly approach.
Note – in very small rooms, a single mic or a combined mic / speaker “pod” may suffice.
[ ] Audio Out
For typical meeting rooms, a line level audio out to drive an external audio system (amp, DSP, speakers, etc.) is required.
Note – in very small rooms, a combined mic / speaker “pod” may suffice.
[ ] Audio Conferencing
The system should support audio conferencing (VoIP / SIP), and ideally should include a dialer user interface on the table (e.g. using a touch panel or mic / speaker pod).
Note – in rooms with a DSP, the audio conferencing may be handled by the DSP instead of the group video system.
[ ] Wireless Presentation
Wireless presentation from laptops and mobile devices, while in a call and not in a call, should be supported – either by the group video system or using an additional device.
[ ] Video Conferencing
The group video system should support standards-based (SIP) video conferencing. Support for video conferencing using a user’s notebook PC and/or a meeting room PC may be of interest to some organizations.
[ ] Control & Management
The ability to control the video conferencing system from a BYO device is recommended. For large scale deployments, centralized device management and control is required.
Additional Comments:
Unlike huddle and teaming / ideation rooms where audio conferencing and content sharing are paramount, the video conferencing experience is very important in these rooms.

Space: Executive Boardroom Definition A well-appointed meeting room intended to host executive meetings, board meetings, etc. These rooms typically include expensive decor elements and furniture, as well as more advanced AV capabilities than standard meeting rooms. Many of the meetings in these rooms include in-room support.
Requirements The requirements for a group video system to support an executive boardroom are as follows:
Topics Description
[ ] Low Cost Not a primary concern. Performance and flexibility trumps price in these rooms.
[ ] Form Factor A split system form factor with a rack mountable base unit is the best option.
[ ] Networking A wired Ethernet connection is a requirement. Wi-Fi and power over Ethernet (PoE) capabilities are not necessary.
[ ] Camera Depending on the room size and layout, these spaces require one or more high performance PTZ (pan / tilt / zoom) cameras. A speaker tracking system is highly recommended.
[ ] Video In / Content In
Multiple video inputs to support cameras and one or more content sources are required.
[ ] Video Out Multiple video outputs to drive several displays are required.
[ ] Audio In / Mic Options
These rooms require multiple microphones.
Recommended Option – A line level input on the group video system to be used with multiple mics and an external mic mixer / DSP. This provides flexibility and the ability to optimize the audio performance (very important in this space). Using a mic mixer / DSP from the same vendor may reduce cost, complexity, and install time.
Viable Alternative – Support for multiple mics on the group video system itself. This simplifies the installation, but offers limited audio adjustment capabilities.
[ ] Audio Out A line level audio out to drive an external audio system (amp, DSP, speakers) is required.
[ ] Audio Conferencing
The system should support audio conferencing (VoIP / SIP), and ideally should include a dialer user interface on the table (e.g. using a touch panel or mic / speaker pod).
Note – in rooms with a DSP, the audio conferencing may be handled by the DSP instead of the group video system.
[ ] Wireless Presentation
Wired content connections will be the norm in these executive spaces. However, wireless presentation capabilities may be of interest to some companies.
[ ] Video Conferencing
The group video system should support standards-based (SIP) video conferencing. Video conferencing using a user’s notebook PC / meeting room PC is not needed in this space.
[ ] Control & Management
These rooms will typically include a control system with a touch panel. Therefore the ability to control the video conferencing system from BYO devices is interesting, but not a necessity.
Remote (centralized) device management and control is a must.
Additional Comments:
The requirements for an executive boardroom are similar to those for a large venue such as an auditorium, theatre, or customer experience center.

Space: Reconfigurable Space Definition Reconfigurable spaces come in many shapes and sizes, ranging from standard rooms in which the furniture can be rearranged to support different use cases to divisible rooms which allows a large space to be divided in several smaller rooms. The primary requirement here is flexibility.
Requirements The requirements for a group video system to support a reconfigurable space are as follows:
Topics Description
[ ] Low Cost Not a primary concern. Performance and flexibility trumps price in these rooms.
[ ] Form Factor A split system form factor with a rack mountable base unit is the best option.
[ ] Networking A wired Ethernet connection is a requirement. Wi-Fi and power over Ethernet (PoE) capabilities are not necessary.
[ ] Camera Depending on the room size and possible room configurations, these spaces require one or more high performance PTZ (pan / tilt / zoom) cameras.
[ ] Video In / Content In
Multiple video inputs to support cameras and content sources are required.
[ ] Video Out Multiple video outputs to drive several displays are required.
[ ] Audio In / Mic Options
The number of microphones required depends on how the space will be used.
For rooms with reconfigurable furniture, ceiling microphones or wireless microphones should be used. For divisible rooms, a DSP is required.
Using microphones and/or a DSP from the same vendor may reduce cost, complexity, and install time.
[ ] Audio Out A line level audio out to drive an external audio system (amp, DSP, speakers) is required.
[ ] Audio Conferencing
The system should support audio conferencing (VoIP / SIP), and ideally should include a stand-alone dialer either on the table (if applicable), wall mounted, or wireless.
Note – in rooms with a DSP, the audio conferencing may be handled by the DSP instead of the group video system.
[ ] Wireless Presentation
In spaces with movable furniture, wired content connections are problematic. For this reason, wireless presentation from laptops and mobile devices is especially important.
The wireless presentation capability can be provided by the group video system or by an external device.
[ ] Video Conferencing
The group video system should support standards-based (SIP) video conferencing. Video conferencing using a user’s notebook PC / meeting room PC is not needed in this space.
[ ] Control & Management
These rooms will typically include a control system with one or more touch panels (depending on the configuration / ability to divide the space). Thus the ability to control the video conferencing system from BYO devices is interesting, but not a necessity.
Remote (centralized) device management and control is a must.
Additional Comments:
The multi-purpose nature of these systems typically requires the use of additional AV equipment including control systems, audio/video switchers, multiple cameras, etc. In some situations, several group video systems may be used.

Conclusion To select the group video conferencing systems that best address their requirements, customers should
do the following:
1) Understand the types of spaces to be video- (or collaboration-) enabled and the common use
cases for each.
2) Review the requirements described in the tables above.
3) Meet with various solution vendors / resellers, ask for details about their recommended
solutions (group video systems, related AV equipment, etc.), and see how closely those
solutions address the needs of each type of space.
Users should apply common sense and logic to this analysis. In general, customers should seek simple
solutions using as few devices as possible. If multiple devices are needed, one should try to use devices
from the same manufacturer to minimize installation time, cabling, and programming and to maximize
feature realization. Whenever possible, standard systems should be chosen over custom solutions.
Occam’s razor applies in the AV / collaboration world, and organizations that deviate from this concept
do so at their own risk.
And finally, organizations should watch out for hype, gimmicks, and blinking lights. Easy-to-buy, easy-to-
install, easy-to-use, and easy-to-manage are the paths to success in the collaboration world.
