Here’s the problem: You need to get audio and video from the sanctuary to an overflow room, a mother’s room, to the kitchen for the crew preparing potluck, to the foyer, and maybe a couple other locations. How do you do it?
Some of you may know about Ethernet baluns; for those that do not, the simplest explanation is they are devices that send audio and/or video signals over Ethernet cable to a remote destination and then provide the original connection type (DVI, VGA, HDMI, etc) to make the “last mile” connection to the end device. These have their utility, to be sure, but Ethernet can be troublesome to terminate and can kink very easily while running through walls and ceilings and these kinks can lead to breaks in the line, necessitating re-running that entire line. However, these balun systems tend to be quite inexpensive, depending on what signal you need to send and how far you need to send it.
