Digital Display Installation in Katy, TX 77491
77491 is one of Katy’s post-office box ZIPs rather than a street-delivery ZIP, so the businesses billing to it are scattered right across the Katy postal area — the I-10 frontage pad sites, the retail nodes hanging off the Grand Parkway, Old Katy around Avenue D, and the newer build-out north of the freeway. What most of them have in common is an exterior screen: a drive-thru menu board, an order-point display, a pick-up window board or a screen facing an open parking field with no shade anywhere near it.
An outdoor board is a different product, not an indoor screen in a box
The most expensive mistake in exterior signage is treating the enclosure as packaging. An outdoor-rated display is engineered around three constraints that simply do not exist indoors: it has to stay readable in full sun, stay inside its temperature limits in a Katy August, and stay dry in a climate that is humid nearly every day of the year.
Those constraints are met by the panel and the enclosure working as one system. Buy them separately, or bolt a bright panel into a weather box with a couple of fans, and you have built a greenhouse with electronics in it. We quote the assembly, not the screen.
The same logic applies at the smaller end. A pick-up window screen under a deep canopy, never touched by rain and shaded most of the day, may only need a high-brightness indoor panel and a drip-protected mount. Saying so when it is true is part of the job.
Readable at two in the afternoon on an open pad site
Brightness is measured in nits, and the numbers sort themselves into clear tiers:
| Where the screen lives | Typical output needed | Why |
|---|---|---|
| Interior dining room or lobby | Roughly 350-500 nits | Controlled light, no sun on the face |
| Under a deep canopy or covered lane | Roughly 1,000-1,500 nits | Bright ambient, reflected glare, no direct sun |
| Open pad site, direct sun on the glass | 2,500 nits and up | Sun on the face swamps a normal panel entirely |
Two things matter as much as the raw number. The first is reflection: a bright panel behind a plain sheet of glass still shows the customer a mirror of the sky. Optically bonded cover glass removes the air gap that causes most of that internal reflection, and it conducts heat out of the panel better as a bonus.
The second is dimming. A 2,500-nit board left at full output after dark is genuinely uncomfortable to sit in front of at a speaker post, and it burns panel life for nothing. Any board we install gets an ambient light sensor driving automatic output, checked at the two extremes before we leave — midday and after dark.
Heat and Gulf Coast humidity: why the enclosure design decides the lifespan
There are two schools of enclosure, and along the I-10 corridor only one of them holds up well.
Vented and filtered. Fans pull outside air through a filter, across the electronics, and out. It is cheaper and it cools well on paper. In Katy it pulls in humid air all summer, pollen every spring and dust off every pad site under construction. The filters are a real maintenance item, and when nobody changes them the airflow collapses and the panel cooks quietly.
Sealed with a heat exchanger. The inside air is a closed loop. An air-to-air exchanger or a small cooling unit moves the heat out without ever mixing the two airstreams, so outside moisture never reaches the board. It costs more up front and it is the right answer for anything that faces weather here.
Cold matters too, less often but expensively. Panels have a minimum operating temperature, and a hard Texas freeze can put an unheated enclosure below it. A sealed enclosure with a thermostatic heater, and leaving the display powered rather than killing it at the breaker overnight, is what carries an outdoor board through a freeze without a cracked panel or a dead backlight.
Getting power and signal out to a free-standing lane structure
A menu board in the middle of a parking field is a small construction project before it is an AV job.
- The foundation is engineered, not guessed. A free-standing board is a sail. The concrete and the bolt pattern are sized for the wind load on that face, the anchor template is set before the pour, and the conduit stubs up inside the pedestal where it will be hidden.
- Two raceways, not one. Branch-circuit conductors and low-voltage signal get their own paths underground. Both get swept elbows and a pull string left in for whatever the customer wants to add in three years.
- Bury depth follows the raceway. The required cover depends on the conduit type and on what is above it — landscaping and a drive lane are not the same number. We size it to the raceway being used rather than to a rule of thumb.
- Do not run bare copper between two structures. A signal cable from the building to a free-standing pedestal ties two separate grounding systems together, and a nearby strike finds that path. Fiber, or an isolated extender with surge protection at both ends, is the right way to cross open ground.
- Protect the branch circuit. Surge protection at the panel and at the board itself is cheap next to replacing an outdoor display after one storm.
Aiming a board at a seated driver, in a market full of pickups
Indoor signage is designed for someone standing. A lane board is read by someone belted into a seat, through a windscreen, at a fixed stopping point — and in Katy a very large share of that traffic is full-size pickups and three-row SUVs sitting a foot or more higher than a sedan.
That spread is the design problem. Set the face for a low car and the truck driver reads the top third through their own dash reflection; set it for the truck and the sedan driver is craning. The workable answer is a face height between the two, a downward tilt so the glass is square to the average eye line rather than to the sky, and the heaviest-weight content placed in the vertical band that both vehicles share.
Three more checks we make on site before anything is anchored:
- Sun behind the customer. Stand at the stopping point at the worst hour. If the sun is over the driver’s shoulder it lands on the glass; a few degrees of extra tilt or a slightly different post position can remove it entirely.
- Distance from the speaker post. A board the driver cannot finish reading before the order point produces a queue that stalls.
- Impact exposure. A pedestal at a tight turn gets clipped by mirrors and trailer hitches. Bollards, or moving the post eighteen inches, is far cheaper than a replacement cabinet.
How EVOTECH stages an exterior install around your trading hours
- Free on-site survey. We walk the lane, measure from the stopping point, locate the panel and the existing conduit, and confirm what is already underground before anyone proposes a trench.
- Itemized quote. Enclosure and panel spec, foundation, trenching and make-good, electrical, mounting, commissioning and exclusions — all written out.
- Underground first. Trenching and the foundation happen in a window agreed with you, with the lane reopened at the end of each day wherever it can be.
- Set, seal, aim. The cabinet goes on the foundation, every penetration is sealed and the board is aimed from a vehicle at the stopping point, not from a ladder.
- Commission at both extremes. Brightness and auto-dimming are verified in daylight and again after dark; the power schedule is set so the board sleeps when you are closed.
- Handover. You get the as-built route, the enclosure service points, and a walkthrough of how to open it safely.
What drives the estimate, and what we get called out to fix
Every quote is itemized after a site visit; we do not publish figures for exterior work because two lanes 400 yards apart on the same feeder road can differ by an order of magnitude. What moves it:
- Whether usable conduit already runs to the lane, or a trench has to cross asphalt that then needs patching.
- Foundation work, and whether the pad site has anything underground that forces a hand-dig.
- Panel size and brightness tier, and sealed versus vented enclosure.
- Whether the work has to be done overnight to keep the lane trading.
- Landlord, franchisor or pad-site approvals on anything that changes the exterior.
The failures we are asked to repair on other installs repeat themselves: an indoor panel inside a weather box, unreadable by ten in the morning; filters nobody was told about; a copper signal run from the building to the pedestal that a storm took out along with the switch port at the other end; and a board aimed from a stepladder that nobody ever checked from a driver’s seat.

Frequently asked questions
Will an outdoor screen survive a Katy summer?
A properly specified one will. That means a panel rated for high ambient temperature inside a sealed enclosure with a heat exchanger or cooling unit, not an indoor display inside a weatherproof box. The enclosure is what does the surviving.
How bright does a drive-thru menu board need to be?
If direct sun lands on the glass, 2,500 nits and up. Under a deep canopy, roughly 1,000 to 1,500 is usually enough. Either way it needs automatic dimming so it is not glaring at drivers after dark.
Do I need a concrete foundation for a free-standing board?
Yes, and it should be sized for the wind load on that cabinet rather than copied from another site. We set the anchor template before the pour and stub the conduit up inside the pedestal so no cable is ever exposed.
Can you reuse the conduit from our old backlit sign?
Often, and it is the single biggest saving available on these jobs. We check for a pull string, confirm the raceway is intact and sized for what you now need, and verify it is not already crowded before we commit to it in the quote.
Why fiber instead of a normal cable out to the lane?
Because copper between two separate structures bonds their grounding systems together, and lightning nearby will use that path. Fiber does not carry it, which protects both the board and the network gear inside the building.
Is 77491 a real service area if it is a PO Box ZIP?
Yes. It is a mailing ZIP, so we simply work from the site address instead. We cover the whole Katy postal area along with Houston, Sugar Land, Richmond, Fulshear and Cypress.
Can you work overnight so the lane stays open?
Yes, and for most drive-thru sites that is the sensible plan. We schedule trenching, the foundation pour and the set around your trading hours and reopen the lane between shifts wherever it is safe to.
