In detail
How a cable run is planned
Every drop starts with a path. We walk it from the display location back to the rack, credenza, or closet, noting ceiling type, fire-rated walls that need a sleeve, and whether the plenum above a drop ceiling requires plenum-rated jacket. Cat6 has a practical limit of about 100 meters per run, so long buildings sometimes need an intermediate switch rather than one heroic pull.
Runs are pulled with a service loop at each end, terminated to a keystone jack or a patch panel rather than a bare plug where possible, and every cable is labeled to match a one-page schedule you keep. Then each run is tested for continuity and wire map before we sign it off.
Cat6, HDMI, or fiber for AV signal
A short direct HDMI run, under about 25 feet, is the simplest way to get video to a screen, and we use it when the source is in the same room. Past that, HDMI becomes unreliable, and the answer is an HDMI-over-IP or HDBaseT extender pair on a Cat6 run, which carries 4K for a hundred-plus feet with no flicker and lets the source live in a rack room.
Fiber makes sense for very long runs between buildings or floors where copper distance limits or electrical noise become a problem. We will recommend the cheapest option that reliably covers the distance, not the most elaborate one.
Retrofit runs in finished spaces
Most cabling work in Austin is in occupied buildings, which means fishing through finished walls and ceilings without leaving a trail. We use flexible rods and a fish tape through drop ceilings, along existing conduit, and down inside walls to a low-voltage bracket at the outlet height. Fire-stop is restored at any penetration we make.
Where a wall is block or a ceiling is hard-lid with no access, surface raceway painted to match is the honest alternative, and we will say so in the quote instead of pretending a hidden run is possible.
