A proper prewire is key. Wire must be up off the ceiling joists, run on its own supported pathways, out of the way of damage by others.&amp;nbsp; It must be run away from noise-producing equipment and other wiring that can cause signal disturbances.&amp;nbsp; Doing a prewire properly doesn't take more space, but it can take more time.&amp;nbsp;&amp;nbsp; Done properly, the investment in a prewire will last a very long time.
