Maximizing AV Control by John Laughlin

  • A well-designed control system adds simplicity, consistency, reliability and efficiency to sophisticated presentation and communication systems.
  • Suppose someone on your staff wants to initiate a video conference with your Dallas office. Does he or she have to know how to turn on the large screen displays, turn on the videoconferencing codec, adjust the lights, zoom in the camera, switch the input on the sound system, adjust the microphones, choose the correct equalizer settings and dial Dallas? Or does he or she simply push a button labeled “Dallas”?

Our experience is that difficult-to-operate AV systems are not used very often –five to 10 hours per month is typical. Yet well-designed systems with simplified controls are normally used 20 to 30 hours per week or more. A control system adds significantly to the cost of a project, but the return on investment can improve by a factor of 10 or more.

Who to involve on your planning team

In evaluating whether a control system is worth the investment, we have found that there are five major areas of concern that you or your AV integrator must address:

1. IT Concerns

For larger AV and video conferencing systems, digital signage networks and any system carrying high definition consumer media (such as news, entertainment or Blu-ray), you’ll want to consider an all-digital Internet Protocol (IP) signal path. At this point bandwidth becomes a major concern. It's important to use an AV integrator who understands network requirements and can work with your IT manager to separate audio/video traffic from data traffic, via either a VLAN or separate networks.

Your IT staff can also be your best resource for AV user support, and if they take on that role, your IT manager should be involved in plans for technical staff training; for helpdesk tools that allow technicians to see and operate room controls from networked PCs; and in any decisions on service and maintenance contracts.

2. Facility Management Concerns

Today’s AV control systems offer several opportunities for environmental system control that your facilities manager will want to be involved in.

On the most basic level, your AV controls should tie into your lighting system, so that lights adjust easily or automatically as needed. It’s also possible to use AV control processors for various “green” initiatives –such as turning AV and lighting on and off automatically, integrating lights and shading into daylight harvesting systems, and including thermostat controls into room scheduling– providing significant energy savings and improving your return on investment.

3. Security Department Concerns

If theft is a risk in your facility, your security manager should know that equipment monitoring is an easy addition to networked AV control systems.

Should someone disconnect a piece of equipment, the system can notify security instantly and trigger cameras to record the theft. With the addition of radio frequency ID tags, the system can track stolen equipment as it moves through your building, aiding apprehension efforts.

4. Administrative Concerns

Your administrative or office manager should know that you can tie your AV control system into your Microsoft Exchange Server to allow staff to use an Outlook calendar to book meeting rooms or classrooms. (It can also tied into Lotus Notes, Novell GroupWise or Planon Integrated Workspace Management). Properly programmed, the system can have the room ready at the scheduled time, with AV turned on, lights adjusted, even a videoconferencing call already connected.

5. User Concerns

Of course, meeting the needs of your system users is your most important concern.

The new control system must be easy to understand and consistent from screen to screen, as well as room to room. Priority functions should be found in the most easily accessible parts of the panel. How well and how intuitively your new control system works will determine the success of your new meeting room or classroom technology.

Be sure representatives of each user group are heard prior to the system design and that they review the proposed control screens and participate in the commissioning process.

This is where a great AV integrator partner will shine. You can buy the hardware from almost anyone – and most integrators have the engineering and programming skills to make your system function. But you need someone who is skilled in listening and analysis, and who has years of practical experience to tailor it to the specific needs of your users.

If you choose your integrator carefully and involve the major stakeholders in your organization, your new system will be used often, your goals for building it will be met and the return on your investment will be high.
