Surveillance Coverage Mapping in Katy, TX 77491
77491 is a Katy mailing ZIP, and the addresses behind it are spread a long way — older streets near the rail line, tracts out toward the county edges, contractor yards and metal shop buildings. That spread is exactly why the plan has to come before the purchase: on a big property it is distance, not camera quality, that ruins most layouts. EVOTECH IT LLC is a licensed and insured low-voltage contractor with 20+ years here and a 5.0-star rating. The site walk and the itemized quote are free.
A Katy address can sit in three different counties, and it matters
Katy is unusual: its addresses straddle Harris, Fort Bend and Waller counties, and a 77491 mailing address tells you almost nothing about where the property physically sits or what services reach it. Before we design anything, we establish which side of those lines you are on, because four practical things change with the answer.
- Who you would file a report with, which affects how you would want footage exported and handed over.
- Which authority has a say if the job touches a new electrical service, a pole or a driveway culvert.
- What internet you can actually get. Fiber on one road and fixed wireless a mile further out is common here, and remote viewing quality is limited by whatever upload the property has, not by the camera.
- Lot size and setback, which is the single biggest driver of cost on a rural layout.
None of this is exotic, but it is the difference between a plan that can be built and a plan that reads well on paper. We note it at the top of your map so nothing later comes as a surprise.
When the gate is four hundred feet from the router
On a suburban lot every camera is comfortably within the reach of one ordinary network cable. On acreage that stops being true at the first corner post, and the whole design becomes a question of how power and data get to the far end.
| How far from the recorder | The practical way to get there | What it costs you in practice |
|---|---|---|
| Within about 100 m / 328 ft of cable | Standard network cable with power over the same cable | Simplest and most reliable — we try hard to stay inside this |
| Further, still on the same building group | A powered mid-point: an extender or a small switch in a weatherproof enclosure | Adds a point that must stay dry, cool and powered |
| Long open runs, or between separate buildings | Fiber with a converter at each end | Unaffected by distance and it does not carry surge between buildings |
| Across a road, a creek or ground you cannot dig | A point-to-point wireless link with clear line of sight | Depends on that line of sight staying clear as trees grow |
Two rules sit behind that table. Buried runs go in conduit, at a sensible depth, with a pull string left in for the next time — direct-buried cable across a property that gets mowed, disced and dug is a repair waiting to happen. And copper should not be the link between two buildings that sit on separate electrical grounds; that is what fiber is for, and it is also the cheapest lightning insurance on the list.
Battery-and-wifi cameras are frequently suggested for gates out here. They are honest about neither the distance nor the weather: signal will not carry, and a camera that has to be taken down and charged every few weeks eventually stops being charged.
Shops, barns, RV covers and the equipment that lives outside
Losses on a property like this are rarely from inside the house. They are trailers and gooseneck hitches, welders and generators, fuel, fencing wire, tools out of a truck bed, and converters cut from under a vehicle parked in the open. A camera plan that only guards the front door of the house is guarding the least valuable thing on the site.
The positions that repeatedly earn their place are: one inside the shop aimed at the roll-up from within, so it captures faces rather than a pair of headlights; one covering the trailer and hitch parking, mounted at vehicle height and along the row; and one at the gate, at plate height, doing nothing except reading what comes and goes. Detached covers and open bays are watched from the closest solid structure rather than by putting a camera on a flimsy post that will move in the first storm.
Metal buildings have their own rules. There is no attic to hide anything in, so cable travels in conduit; mounts land on purlins or a properly backed plate, never on bare sheet; and each penetration gets a weather boot and sealant. The recorder does not stay in an uninsulated shop — summer heat inside one of those is hard on hard drives — so part of the walk is finding it a conditioned home and planning the run back to it.
Open sky, low sun and everything that lives outdoors
Cameras on an open property face conditions a suburban camera never meets, and most of it can be designed out rather than lived with.
The sun sits in the lens twice a day. A driveway running east–west means a gate camera looking straight into a low sun at dawn or dusk, which is precisely when vehicles arrive. Offsetting the aim a few degrees, using the sunshield properly, or moving the camera to the other side of the drive fixes for free what no image setting will.
Storms and surge. Wide open ground and long metal runs are a bad combination. Surge protection at the point cable enters a building, a proper ground, and fiber rather than copper between separately-grounded structures are the three measures that matter. They belong in the design, not in a later repair visit.
Wildlife and insects. Mud daubers build inside housings and under sunshields, spiders spin across the lens and light up the infrared at night, and gravel dust films a dome within a season. Mounting height, a sensible tilt and a wipe-down once or twice a year keep all of it manageable. We will tell you which positions need that attention and which will look after themselves.
What you receive, and what moves the number
You get a marked-up site sketch showing every proposed camera, its direction, what it is responsible for, the cable route back and any point that needs a powered mid-span or fiber. Alongside it is an itemized quote, so you can see the cost of the gate position separately from the cost of the shop position and decide for yourself whether both go in now or one goes in later.
What moves the number on a property like this:
- Total cable distance, and how much of it needs conduit or trenching.
- Whether any usable conduit or pathway already exists.
- How many separate buildings are involved, and whether they share power and ground.
- Gate details — existing power at the gate, the approach geometry, and whether plates matter to you.
- The internet service at the property, if you want to view it remotely.
- How many days of footage you want kept.

Frequently asked questions
My mailing address says Katy but I am nearly at Brookshire. Do you still come out?
Yes. We work Katy, Houston, Sugar Land, Richmond, Fulshear, Cypress and the surrounding area, and out here the mailing address rarely matches the map anyway. Tell us the cross streets or drop a pin when you call and we will confirm straight away rather than leaving you guessing.
My gate is a long way from the house. Can a camera actually reach it?
Almost always, but the method changes with the distance. Inside roughly 100 m a single network cable carries both data and power. Past that we either add a powered mid-point, run fiber, or use a line-of-sight wireless link, depending on the terrain and whether there is power near the gate. Working out which of those applies is one of the main reasons the walk exists.
Can you genuinely read license plates at the road?
With a camera dedicated to that job, yes — mounted at roughly plate height, aimed along the direction of travel rather than across it, at a point where vehicles slow, and set up for the reflective plate rather than for the scene. What does not work is expecting a wide overview camera to also produce plates; it is a different lens, a different angle and usually a different exposure setting.
Does a metal shop building need anything special?
It needs conduit instead of concealed cable, mounts backed onto structure rather than sheet, sealed penetrations, and a recorder located somewhere conditioned rather than inside the shop. It also rules out relying on wireless inside the building, because a steel envelope is very good at blocking the signal people assume will be there.
We get serious lightning out here. What actually protects the system?
Three things, all designed in from the start: surge protection where cable enters a structure, a proper ground reference for the equipment, and fiber rather than copper between buildings that sit on separate grounds. Nothing makes a system immune, but those measures are the difference between losing one device and losing the recorder and every camera attached to it.
Will cattle and deer set the alerts off all night?
They will if the whole frame is armed. The plan defines which region of each view triggers an alert — the gate approach, the shop apron, the trailer row — and leaves the open pasture out of it. You still record everything; you are only alerted about the parts you asked to be alerted about.
