5 Essentials of Smart AV Design for Houses of Worship

Posted by admin on September 29, 2015 10:31 am

Audio/Visual technology is now one of the top items on the list when new pastors setup churches and in updating established churches. It doesn’t matter the size of the House of Worship (HOW), whether there are 20 members or 20,000, technology is revolutionizing how people engage with each other and consume content. And it’s not just happening on Sundays; many churches are working through the week to produce compelling videos that can help reach the community they serve and generate donations.

Like all businesses, HOW are all about producing quality content as inexpensively as possible, but unlike all businesses, they also have to deal with the realities of the limited capacity of volunteers’ time spent managing the AV workflow when they have their own jobs and businesses to attend to. It is important that whatever hardware and software solutions are adopted, that it be easy and fast for people to learn to use, because quite often volunteers are pulled from the untrained congregation. Members may be intimidated by camera work, directing, editing, projection, sound mixing, etc., but if you are willing to take time out and teach skills and processes, you will find the reliable ones and you just might help someone launch their career in AV!

The five essential elements to a smart AV design for HOW are:

  1. Ability to easily create multiple types of engaging and timely content
  2. Ability to distribute content where it needs to be seen
  3. Serving the community while reaching out to a broader audience
  4. Creating a flexible, expandable AV system
  5. And the fifth, of course, is to be able to do all that and still be affordable.

Create multiple types of engaging and timely content

Content being produced by a HOW ranges from announcement and music videos, to still-graphic bulletins, presentation welcoming slides, IMAG (large-scale video projection so those seated far away can see the performers in detail), playbacks, ads, motion backgrounds, podcasts, website, social media and other custom content. One important thing to remember about content creation; it should be engaging but not distracting and taking away from paying attention to the speaker’s message.

Distribute content where it needs to be seen

Once content is ready it needs to be sent out to all the appropriate engagement points. In the sanctuary where services, conferences and large weddings are held, typically there is a large center projector screen with visuals and IMAG, while on the side screens they simulcast lyrics, scriptures, graphics and live cuts. In stadium “mega-churches,” there are typically multiple flat panels or projector screens may be setup as a large video wall above and on both sides of the stage.

Additional places where flat panel displays are typically found include the church lobby, the chapel where funeral services and smaller weddings are held, the fellowship hall where breakfasts, meetings, and workshops are held, overflow rooms where attendees can view the services when the sanctuary is full, classrooms, gymnasium, church library, and outdoors digital signage seen from the street.

Video distribution in HOW typically go over CATx/HDBaseT or Ethernet/IP; possibly fiber. Copper cables are more cost-effective in shorter runs for smaller networks, such as equipment within the same rack or within a 30 meter range. Ethernet/IP is a hot growth area due to its flexibility, products that are easy to install and use, support point-to-point and point-to-multipoint streaming, as well as, distributed matrix switching for small to large configurations. Fiber, on the other hand, is the only sensible choice for long runs, large data needs, and very high speed interconnects, point-to-point.

Serve the community while reaching out to a broader audience

Some HOW’s utilize online audio streaming to create their own online radio station that broadcasts music and worship services, typically using a regular Internet connection for the low-bandwidth streaming. The next step up from there is distributing video to people’s homes. While this can be beneficial to reach people in the community who may not be able to attend services for health reasons and to reach people beyond the community, be aware that there is a downside where people who could attend may not, opting to use streamed services instead.

Churches who want to stream HD and UHD video need a good fiber optic line for both up and down video streams. While there are ways to do it for less, the difficulties associated with poor bandwidth will far outweigh the cost advantages.

Create a flexible, expandable system

A worship AV system that can capture, edit, store and distribute video to all needed end-points can quickly turn into a costly setup. Hardware requirements of a HOW may include: video cameras, projectors, projector screens, interactive whiteboards, indoor digital signage displays, outdoor digital signage, digital signage media player, digital video recorder, lighting fixtures, stage racks, lighting console, sound console, monitor console, monitor hub, microphones, headset mics, handheld audio transmitters, beltpack audio transmitters, wireless audio receivers, speakers, matrix switch, Gigabit Ethernet switch, production switch, reclocking distribution amplifiers, splitters, encoders/decoders, converters, media video-on-demand server, CD/DVD/Blu-ray players, DVD copiers, computers/laptops, converters, and of course, cabling.

Churches also need to invest in software, which may include a professional post-production editing package, a lyric and media presentation package, a digital signage content manager, PowerPoint, mobile apps, an internet broadcasting package, XXXX. Churches that broadcast music and video will also need a CDN (content distribution network) and to consider copyright and royalty payments for copyright owners.

As you can see, a worship AV system can run from several hundred into the millions. In choosing the right equipment and software for a HOW it always comes down to, what is the vision of the church, what sources need to be distributed, how many end-points are required and where, which technologies can help ease the steps involved for volunteers, and what is the overall budget?

Affordable
