Cat5e vs Cat6 vs Cat6a vs Cat8

6 min read

Category cable decides how fast your wired network can run. This guide has its own page with the full comparison table, what each cable type is actually for, and the one label you can ignore.

TL;DR: Cat6a is a good default for new runs. Cat6 is fine for shorter runs. Cat8 is overkill outside a server rack. And "Cat6e" is not a real standard.

Wi-Fi bands explained

THE FAR ROOM 2.4 GHZ COVERS THE WHOLE HOUSE AT A CRAWL WEAK OUT HERE 5 GHZ: FAST, FADING TWO WALLS OUT MOSTLY GONE OUT HERE 6 GHZ BARELY LEAVES THE ROOM WIRE THE BACKHAUL, PUT 6 GHZ IN THE RIGHT ROOM SHORT RANGE IS FINE WHEN THE AP IS CLOSE

Modern Wi-Fi runs on three bands. Each trades range for speed differently, and knowing which is which explains most "why is it slow over here" problems.

2.4 GHz

Best range and the best at getting through walls, but the slowest and the most crowded. Every cheap smart plug and old device lives here. Good for distance and low-bandwidth gear.

5 GHz

The workhorse: fast, less crowded, but shorter range and weaker through walls. This is what your laptop and phone should be on in most of the house.

6 GHz (Wi-Fi 6E / 7)

A big block of clean spectrum and the top throughput, but the shortest range and the weakest through walls. Best in the same room as the access point for high-bandwidth work.

More bands don't fix bad placement. An access point wired to the right spot beats a faster router in the wrong one.

Wired, wireless, or a relay

WIRED SWITCH CAMERA WIRELESS HUB SENSOR RELAY SIREN WIRED: INSTANT AND STEADY WIRELESS: GOOD WHERE WIRES CANNOT GO THE RELAY: ONE JOB, ZERO SOFTWARE SENSOR OFFLINE THE HUB DIED. GUESS WHICH TWO KEPT WORKING. CAMERAS: WIRED BATTERY SENSORS: WIRELESS GATE AND SIREN: RELAY DESIGN FOR THE DAY SOMETHING DIES

There are three ways to get a signal from here to there: a wire, the air, or a bare contact closure. They are not competitors so much as tools for different jobs. The wire wins on speed and reliability every day it is installed. Radio makes sense wherever trenching or fishing a wall is not worth the trouble, and a relay earns its spot by being too simple to be dragged into a network failure.

The hub test is how we choose. Imagine the smart hub rebooting at the worst moment: everything that routes through it pauses with it. Cameras and anything that carries video or calls should be wired. Battery sensors on doors and windows are the right fit for radio. And the one or two things that must work in a storm with the network down, a gate release, a siren, get a relay and a backed-up power feed, because a closed contact works with the cloud up or down.

When we design a system, every device gets asked the same question: what happens to you when the hub dies? The answer decides which of the three paths it gets.

Wire distance and gauge

POWER 12V VDROP = 2 x LENGTH x OHMS x AMPS SIGNAL SWITCH 0 M 50 M 100 M 18 AWG AT THE FAR LIGHT: ABOUT 10.7 V THIN WIRE, LONG RUN: THE MARGIN IS GONE 12 AWG AT THE FAR LIGHT: ABOUT 11.7 V FOUR TIMES THE COPPER, A QUARTER OF THE DROP FADING, NOT DIMMER PAST 100 M, THE ERRORS PILE UP FRESH 100 M STARTS HERE A SWITCH MID-RUN RESETS THE BUDGET THICKNESS FOR POWER, QUALITY FOR SIGNAL

Copper resists. The math is one line: double the run length, multiply by the wire's resistance and the load's amps, and that is the voltage that never reaches the far light. On a 12 volt landscape run, fifty feet at two amps costs about 1.3 volts on 18 gauge wire, past the 10 percent drop the design rules allow, while the same run on 12 gauge costs a third of a volt. Power problems at distance are solved with thickness: heavier gauge, shorter or split runs, a feed from the middle.

Data cable works on a budget instead. The standard gives a twisted-pair channel 100 meters, 90 for the permanent run and 10 for patch cords, and past that the link turns unreliable: errors climb, gigabit drops to a lower speed, and connections get flaky. Thicker conductors do not buy meters here, because the limit is signal quality across the whole run. When a camera sits past the wall, the fix is a switch partway that resets the budget, or fiber when the distance is serious.

Both lanes get engineered before we pull anything: the power run gets the drop math with margin, and no data run gets designed past 90 meters on paper. If a light at the end of your yard looks tired, bring us the run length and the lamp wattage and we will tell you the gauge over the phone.

Covering acreage, hop by hop

HOUSE BARN GATE RADIO THINS OUT HERE THE GATE, STILL DARK ONE BUBBLE AT THE HOUSE. THE REST IS ACREAGE. 100 M 100 M FENCE CAMERAS, FED BY WIRE ALONG THE WAY THE BARN BECOMES THE MID-FIELD NODE COVERAGE BUBBLES, LINKED END TO END BIG LAND GETS COVERED ONE HOP AT A TIME

Acreage changes the problem. Cameras and Wi-Fi mounted on the house cover the house; a few hundred feet out both are gone, and the places that most need watching, the fence line and the gate, are exactly where nothing reaches. Radio thins with distance, and the wire budget from the last guide still applies: 100 meters per run, then you need a node.

So big land gets built as a chain. Fence-line cameras ride a wired run with a fresh node before each 100 meters. A barn or well house mid-property becomes infrastructure: power is usually already there, a switch starts the 100 meters over, and an access point pushes radio farther out. And the far gate, where trenching costs more than the gear, gets a solar sensor that reports to the barn instead of shouting all the way home.

We plan acreage with a coverage map like this one: bubbles that overlap and hops that stay inside their limits, until no corner of the property line is left dark. Walk the fence with us once and we will price every hop.

THE HOUSE THE WORKSHOP LIGHTS DIM AT SAW START TRIPPED ONE LONG SKINNY CIRCUIT: THE SHOP RUNS ON FUMES LIGHTS HOLD STEADY A REAL FEEDER AND A PANEL WHERE THE WORK IS N: FLOATS G: BONDED GROUNDS AND NEUTRALS PART WAYS PAST THE HOUSE SAME TRENCH, SECOND CONDUIT POWER PANEL AND POE PANEL, SIDE BY SIDE THE SHOP JOINS THE SYSTEM, NOT JUST THE GRID

A detached shop fed by one long branch circuit is an extension cord with drywall around it. Motors pull several times their running current at startup, so the lights dim every time the saw spins up, the tools bog when the cut loads them, and the breaker that trips is all the way back in the house. The fix is a feeder: one properly sized run that does the distance once, landing in a subpanel with its own breakers where the work actually happens.

Two rules make a subpanel right. The neutral and ground bond exists at the main panel and nowhere else: past the house they separate, with the subpanel's neutral bar floating and its grounds on their own bonded bar, because a second bond would put everyday current on bare wires and metal boxes. And a detached building gets its own disconnect and its own grounding electrode, both required by code, with two rods as the standard way to meet it. In Houston the whole job is permit work, and we coordinate the licensed trades and the permit.

If your shop lights flicker when the saw starts, that is voltage drop you can see. A feeder, a subpanel, and a PoE cabinet beside it turn a shop into part of the property system, and we quote all three as one trench.

Why I never use CCA wire

SOLID COPPER COPPER-CLAD ALUMINUM COPPER THROUGH THE WHOLE CONDUCTOR THIN COPPER SKIN OVER AN ALUMINUM CORE PoE SWITCH CAMERA STAYS COOL PoE SWITCH CAMERA RUNS HOT SOLID CONTACT CONNECTION LOST CAMERA DROPS STABLE UNDER PoE LOAD TERMINATES CLEAN TIA AND UL LISTED OVERHEATS UNDER LOAD BRITTLE TERMINATIONS NOT TIA OR UL LISTED ASK IN WRITING: COPPER OR CCA?

CCA is copper-clad aluminum: an aluminum wire with a thin copper coating. It's cheaper than solid copper, and it's a problem.

  • Higher resistance, so it runs hotter, especially under PoE that pushes power down the cable.
  • Aluminum is brittle, so terminations crack and fail over time.
  • It isn't compliant with TIA or UL for permanent installs.

The result is intermittent drops, dead PoE devices, and a fire risk on longer high-power runs. Cheap installers use it because you can't see it once it's in the wall.

I use solid copper, every run. If you're getting a quote from someone else, ask in writing whether the cable is solid copper or CCA.

Safe electrical tips for homeowners

MAIN PANEL HOVER OR TAP ANYTHING ON THE WALL GREEN IS YOURS. RED IS OURS. TRIPPED RESET ONCE TRIPS AGAIN TWICE IS THE BREAKER TALKING. CALL. FIND THE WHY BEFORE THE NEXT RESET

Some things are fine to handle yourself. Others aren't worth the risk. A rough line:

  • Fine to do: swap a like-for-like light fixture or a smart plug, reset a tripped breaker once, replace batteries in smoke and sensor units.
  • Leave it: anything inside the panel, adding circuits, aluminum branch wiring, anything warm to the touch, or a breaker that trips again right after a reset.

A breaker that keeps tripping is doing its job. Don't keep resetting it, find out why. Warm outlets, a burning smell, or scorch marks mean stop and call.

This is general guidance, not a substitute for a licensed electrician on anything beyond the basics.

Wiring while other trades are on site

In an open attic or wall, low-voltage data and coax are easy for other trades to nick, crush, or re-route. A few things protect your investment:

  • Keep runs labeled at both ends so nobody mistakes a data line for scrap.
  • Ask trades not to staple or tightly tuck data the way they would electrical. Data cable is sensitive to crushing.
  • If a line has to move, have it moved properly, not folded or stapled to clear a path.

If you're mid-remodel, a quick call before drywall goes up is the cheapest insurance there is.

WALL PLATE SWITCH DROPS COME AND GO A CRUSHED LINE LIES: IT MOSTLY WORKS PART BOUNCES BACK PART LIMPS ON A TWIST SPLICE TURNS SIGNAL INTO ECHOES CLEAN END TO END CUT BACK AND RE-TERMINATED: CLEAN AGAIN A PROPER FIX COSTS LESS THAN THE CHASE

If a cable run gets cut, crushed, or pulled after it's installed, don't try to splice data or coax yourself. A twisted splice rarely holds a signal and usually causes worse, intermittent problems that are harder to find.

Damaged structured cabling normally needs proper re-termination or a fresh pull. Call for a repair quote. Damage after completion isn't covered by the workmanship warranty, but it's usually a quick fix.

Care guide: the home office

THE CORE UPS ACCESS POINT THE HOUSEHOLD THE DESK THE CALL THE CALL STUTTERS 8 PM: EVERY SCREEN SHARES THE SAME AIR THE CALL HOLDS STEADY ONE WIRED DROP TAKES THE DESK OFF THE AIR THE POWER SAGS FOR A SECOND UPS CORE ON BATTERY DESK PC ON BATTERY THE LIGHTS DIPPED. THE DESK DID NOT. WIRED FOR THE CALL, BATTERY FOR THE BLINK

A home office lives and dies by its connection. A wired drop to the desk beats Wi-Fi for video calls and big uploads every time: lower latency, no drop-outs when someone else streams, and it frees the airwaves for everything that has to be wireless. Here's how to keep one running well.

If you do one thing: run a single Cat6a drop to the desk and plug the computer straight in. It's the cheapest upgrade with the biggest payoff for calls and uploads.

Wire what matters, leave the rest on Wi-Fi

The desktop, the dock, and anything that does video calls or large transfers belong on a cable. Phones, tablets, and the printer are fine on Wi-Fi. If you can't pull a wall drop yet, a wired-backhaul access point in the office is the next best thing: it puts a strong signal in the room without fighting through walls.

Place the access point well

  • Mount it high, on a wall or ceiling, not on the floor or behind a monitor.
  • Keep it out in the open, away from the microwave, cordless-phone base, and big metal objects.
  • One good access point in the right spot beats two fighting each other from bad ones.

Protect the power

Put the router, modem, and any network gear on a small line-interactive UPS. A brief flicker won't reboot your equipment mid-meeting, and you get a few minutes to save and shut down cleanly in an outage. Plug the desktop into the battery side too; leave the printer and monitor on the surge-only side.

Keep it tidy and labeled

Label both ends of every cable and leave a little slack so gear can be pulled forward to service. A two-minute label job now saves an hour of tracing later. Dust the vents on the router and any rack gear once a season so it doesn't cook itself.

Want it done once, properly? I'll run a clean drop, set the access point, and put it all on battery backup so your workday doesn't depend on a power flicker.

INSIDE THE MEDIA CABINET PLAYER RECEIVER RUNNING HOT A SEALED CABINET HOLDS THE HEAT IN INSIDE THE MEDIA CABINET PLAYER RECEIVER SETTLED COOL COOL AIR IN LOW, HOT AIR OUT HIGH ON WI-FI BUFFERING ON THE WIRE PLAYING 4K LABELED AT BOTH ENDS MOVIE NIGHT: THE WIRED SCREEN HOLDS 4K COOL, LABELED, AND WIRED: A RACK THAT LASTS

A home theater is a lot of gear working together: sources, an amp or receiver, speakers, a display, and the network behind it all. Treat the rack like the heart of the system and the whole thing stays reliable and easy to live with.

Heat and dust are what kill AV gear early. Give the rack room to breathe and dust it once a season, and most of your equipment will outlast the trends.

Keep the rack cool

  • Leave air gaps above hot components like the receiver, and don't stack gear directly on it.
  • Make sure the cabinet or closet actually vents; a sealed cabinet bakes everything inside.
  • If it runs in an enclosed space, a quiet rack fan pulling air through pays for itself in longevity.

Label the sources and dress the cables

Label every HDMI and speaker run at both ends. When a source acts up, you want to find the right cable in seconds, not unplug the whole rack to trace it. Leave a service loop of slack behind the gear so a piece can be pulled forward without disconnecting its neighbors.

Wire the streamers, don't trust Wi-Fi

4K streaming and a wireless connection fighting for bandwidth is where most "it keeps buffering" complaints come from. A wired drop to the media rack makes streaming rock-solid and keeps firmware updates quick. If the TV is wall-mounted, run the cabling in-wall to a recessed box so there are no dangling cords.

Protect and maintain

Put the rack on a quality surge protector or, better, a line-interactive UPS: a power blip won't drop the projector lamp or scramble a receiver mid-movie. Dust the fans and vents once a season, and check that the slack and labels are still in place after any gear swap.

Planning a build? I'll size and ventilate the rack, run in-wall HDMI and a wired drop, and label it so a future change is a five-minute job, not a teardown.

CLOUD-RUN LOCALLY RUN HUB TWO HOUSES, SAME TRICKS, DIFFERENT WIRING NO ANSWER FROM THE CLOUD STILL RUNNING THE INTERNET DROPPED. ONE HOUSE WENT DARK. MATTER THREAD Z-WAVE ZIGBEE OPEN STANDARDS MEAN THE HUB OUTLIVES THE BRANDS THE CORE OF A SMART HOME LIVES AT HOME

A smart home should make life simpler, not add a pile of apps that each control one gadget. The trick is to build on a foundation that runs locally and to keep it organized from day one. Do that and your automations will still work in two years, even when a cloud service shuts down or your internet drops.

Local control is the whole game. If the lights still turn on when the internet is down, you built it right. If the house goes dumb during an outage, you're renting your home from someone else's server.

Start with a hub that runs locally

Pick a hub that keeps your automations on the device in your house rather than in the cloud, one that speaks the open standards (Matter, Thread, Z-Wave, Zigbee) so you're not locked to a single brand. Cloud-only gadgets are fine as extras, but the core routines that you rely on every day should run locally so they're fast and they don't depend on a working internet connection.

Name everything clearly

  • Use plain, consistent names: "Kitchen Ceiling," not "Switch 3."
  • Group devices by room so voice commands and dashboards make sense.
  • Write down what each automation does and what triggers it. Future you will thank present you.

Wire the backbone where you can

The hub, cameras, and any always-on bridges are happiest on a wired connection: it's reliable and it keeps your Wi-Fi clear for phones and laptops. Cameras especially belong on PoE: one cable for power and data, recorded to a box you own, with no monthly fee.

Keep it maintainable

Resist the urge to add a dozen apps. Fewer, well-chosen devices on one hub beat a drawer full of half-used gadgets. Update firmware a couple of times a year, keep a short note of your device names and automations, and your system stays something you control instead of something that controls you.

Want a smart home that keeps working when the internet doesn't? I'll set up local control, wire the backbone, and label it so it stays simple to live with and easy to expand.

A smart home is three layers wearing one app. The comfort layer is the part guests notice: shades that move on a schedule and switches you can reach from anywhere. The security layer covers the openings: a lock with codes and an auto-lock rule, plus a doorbell that records the porch. Stick-on sensors report every open and close.

Under both sits the layer nobody screenshots: the access point that carries the radios, the hub that runs the routines, and the wiring that feeds them. Get that layer right and every gadget above it works better. Skimp on it and doorbell clips stutter and remote access drops right at dinner.

The four shapes of automation

7:00 PM PORCH LIGHT THE SCHEDULE: ONE ACTION ON A TIMER MOTION HALL LIGHT IT FIRES AT NOON TOO THE TRIGGER: ONE EVENT, ONE RESPONSE MOTION AND IT IS DARK HALL LIGHT NOON: BLOCKED AT THE GATE NIGHT: STRAIGHT THROUGH THE CONDITION: ONLY WHEN IT MATTERS GOODNIGHT DOORS LOCK LIGHTS OFF HEAT SETBACK ALERTS ON THE SCENE: ONE PRESS, A WHOLE ROUTINE ALL FOUR RUN ON THE LOCAL HUB, INTERNET OPTIONAL

Automations come in four shapes. A schedule acts on the clock: porch light at seven, off at sunrise. A trigger fires on an event: motion in the hall, light in the hall. A condition adds a gate, so the same motion only matters after dark. And a scene bundles the lot: one button, and the hub runs a scripted routine.

The shape matters less than where it runs. Every example above executes on the local hub, so none of it needs the internet to work. That is the standard we build to, and it is why the goodnight button still works during an outage.

Bring us the one routine you wish your house did by itself. We will tell you which of the four shapes it is, what it needs, and whether the parts you already own can do it.

Blind spots, and why cameras overlap

Every solid thing on a property casts a camera shadow: the house itself, the shed, even a healthy tree. One camera, however good, sees one set of angles out to one range, and everything else is dark.

That is why we design with overlap. Cameras are placed so that the ground one loses to an obstacle sits squarely in a neighbor's view. Overlap is not wasted coverage; it is what keeps a single failure, a spider web, or a glare from opening a hole in the fence line.

We aim for under 10 percent uncovered ground on a typical lot, we show you the remaining slivers in red before we install, and you decide if they matter. Usually that is 8 cameras on a residence, fixed, no rotation.

KEEP THE GLASS DARK.

Most night cameras see by an infrared ring built around the lens. To you it is invisible, or at most a faint red dot. To the neighborhood insects it is a warm glowing beacon in an otherwise dark yard, and to the spiders it is a stocked pond: they rig webs across the one piece of glass you need clean. An inch from the lens, a single strand catches the IR and blooms white, and every breeze becomes a motion alert at two in the morning.

After the fourth ghost alert, people stop looking. That is the real damage: not the web, but the swipe reflex it trains into you, so the one alert that matters gets dismissed with the rest. The fix costs almost nothing. Hang the illumination on its own mount about ten feet from the camera, and switch the camera's built-in IR emitters off. The insects orbit the light, the spiders follow the insects, and the lens watches from the dark with nothing in front of it worth a web.

Every night-critical camera we install gets its light separated from its glass and its built-in IR turned off. It is a small bracket, one settings change, and ten minutes on a ladder, and it is the difference between a camera you trust at 3 AM and one you have learned to ignore.

Why surge protectors, and where

SERVICE LINE MAIN PANEL THE TV RACK IT ONLY NEEDS MICROSECONDS THE BIG ONES RIDE IN ON THE SERVICE LINE EVERYTHING DOWNSTREAM TAKES THE HIT UNPROTECTED: THE SPIKE ENDS INSIDE YOUR GEAR GEAR STAYS GREEN CLAMPED AT THE PANEL, CAUGHT AT THE STRIP INDICATOR: REPLACE ME PANEL SPD FIRST RATED STRIP AT THE GEAR UPS: DIFFERENT JOB SACRIFICIAL BY DESIGN. CHECK THE LIGHT. PROTECTION THAT WEARS OUT IS PROTECTION THAT WORKED

A surge is a brief, violent overvoltage. A nearby lightning strike or a utility switching event sends a spike down the line that lasts microseconds and can carry thousands of volts, and your own AC compressor kicking off can do the same from inside the house. Every board in the house sees the same spike at the same moment, and a modern house is full of boards.

The defense is layered. A whole-home SPD clamps the bulk of the hit at the panel, and joule-rated strips at the gear catch what slips past. Both are sacrificial: they spend themselves absorbing hits. That is why the SPD has an indicator light, and why a strip that took a big hit should simply be replaced. One more distinction matters: a surge strip is not a UPS. Spikes are the strip's job. Riding through an outage takes a battery, and security gear ultimately wants both.

We recommend a panel SPD plus rated strips at the rack on every system we design. It is cheap insurance for the most expensive shelf in the house. If your SPD's light is dark, or your strip predates your TV, mention it at the next check-in.

A standby generator is the right call for a Houston outage season, but it does not start instantly. The transfer switch has to confirm the outage, crank the engine, and hand the house over: seconds if everything is automatic, minutes or more if someone has to wheel a portable out and throw a cord. That window is the gap, and inside it your cameras, router, and recorder are dark. They also do not come back the instant power does, because network gear reboots on its own slow schedule.

The gap has an audience. Outages are public: the whole street knows, and anyone who wants your cameras dark can simply wait for one. The fix is not a bigger generator. It is a small UPS under the security stack, which only has to carry a few efficient devices across a few minutes, and because the cameras run on PoE, the same battery that holds the switch holds the cameras plugged into it.

We size the UPS to the stack it carries and the generator it waits for, with margin. If you already own a generator, the UPS is the missing half of the outage plan. Ask at the next visit and we will measure what your gap actually is.

Underground wiring, done to depth

PLAN ON IT. 811 PAINT GAS WATER THE HOUSE 811 FIRST. TWO BUSINESS DAYS. THEN WE DIG. BURIED RIGHT IS BURIED ONCE

Underground wire is safe exactly as deep as the code says it is. The National Electrical Code sets minimum cover by wiring method: 24 inches for direct-burial cable, 18 for PVC conduit, 6 for rigid metal conduit, 6 for low-voltage landscape runs, and a 12 inch allowance for a GFCI-protected 120 volt residential circuit on a 20 amp breaker. Depth is only half of it in this town, though. Houston's local amendments do not allow bare direct-burial cable for branch circuits: the run goes in a raceway or another approved protected method, which is why our answer is almost always conduit, and the work pulls a city permit either way.

Before any of it, 811. Texas law puts the locate call on whoever digs, with two business days of notice, and the marks come free. We hand-dig near marked gas and water, keep the trench clear of them per the utility's standard, lay warning tape over every run whether the code demands it or not, and treat the whole thing as a wet location, because in Houston it will be one.

Bring us the run you are planning: gate power, or a camera at the back fence. We will quote it in conduit at code depth, permit included. If someone quotes you a shallow trench and a garden spade, ask them which row of Table 300.5 they are reading.
