Door Entry & Access Control in Houston, TX 77024
On a wooded Memorial acre the front door is not where access control starts. It starts at the street, at a gate a hundred or four hundred feet from the house, on a lot full of mature roots, irrigation lines and everything a Gulf Coast summer does to outdoor electronics. That distance — and that weather — shape the entire design.
One ZIP code, two completely unrelated jobs
77024 covers the Memorial Villages — Bunker Hill, Hunters Creek, Piney Point, Hedwig — and it also covers the office and medical corridor along I-10 near Memorial City and Town & Country. Those two halves want almost nothing in common from an access control system, and a quote built for one is wrong for the other.
The Villages half is large wooded lots, deep setbacks, long private drives, homes ranging from original 1950s and 1960s ranches through recent custom rebuilds, and very often a guest house, pool house or detached garage that needs its own answer. The work is outdoor, distance-limited and weather-exposed.
The corridor half is leased suites in multi-tenant buildings where the landlord owns most of the doors you would like to control. Almost everything below is about the first half; if you are in a suite off Gessner or Bunker Hill Road, the sections on Villages permitting and gate hardware will not apply to you and the conversation starts with your building engineer instead.
On most Memorial properties, the drive gate is the real front door
Nearly every call we take out here starts with the gate, and the first thing worth knowing is that a working gate operator almost never needs replacing to gain credentials.
How access control attaches to an existing gate
A swing or slide operator has a control board with inputs: an open command, safety devices, and a free-exit input. Access control sits in front of that board. The reader, keypad or video intercom reports to a controller, the controller closes a dry contact, and the operator sees the same signal it would see from a remote. Your existing operator, remotes and safety devices keep working exactly as they do today.
The four things a gate entry actually needs
- An entry device — keypad, credential reader, video intercom, or a combination. A video intercom is the one most households eventually want, because it answers the question the gate poses: who is that.
- Free exit — a buried loop, a probe, or a sensor so nobody badges to leave their own driveway.
- Responder access — fire and EMS have to get through. That is arranged with the local department as a key switch, a lock box or a receiver, and it is settled before the gate goes live, not after.
- Untouched safety devices. Photo eyes and reversing edges belong to the operator and are not ours to bypass, shorten or work around, ever.
The feature people actually came for
It is rarely security in the dramatic sense. It is a separate code for the pool service that only works Tuesday mornings, a landscaper code that only works Thursday, a housekeeper credential you can end on a phone the day the arrangement ends, and a list showing which of those opened the gate and when. Shared-code-for-everyone is what people are trying to escape.
Long drives: voltage drop, the 100-metre wall, and where the electronics live
Distance is the engineering problem on a Memorial lot, and it bites in two separate ways.
Power. Low-voltage DC loses voltage over a long conductor. A device rated at 12 volts may measure fine at the power supply in the garage and still fail to operate reliably at a gate several hundred feet away, particularly at the moment it draws its highest current. The fixes are heavier conductors, a device that runs on 24 volts, or — usually the right answer — putting a power supply at the gate and running only signal from the house.
Data. Ethernet is specified to roughly 100 metres, and a long Memorial driveway eats that. The options are fiber out to the gate with media conversion at each end, a powered midpoint in a weatherproof enclosure, or a cellular video intercom that needs no data cable back to the house at all, only local power.
What goes in the ground
- Conduit, always — not direct burial — with a pull string left in it for whatever comes next.
- Sweeping bends rather than hard elbows, so cable can actually be pulled through later.
- Routed clear of irrigation laterals and outside the root plate of the mature oaks and pines, which on these lots means hand-digging or boring rather than a trencher near the canopy.
- Bored under the drive rather than cutting a finished surface.
- Both ends marked, so the next person to dig knows it is there.
What actually kills outdoor access hardware on a wooded lot here
Gate hardware in this part of Houston does not usually fail because it was cheap. It fails for five specific local reasons, all of which are preventable at install.
- Surge. Any conductor leaving the building is an antenna in a Houston thunderstorm. Surge protection at both ends of the run and a proper ground at the gate is not an upsell; it is the difference between replacing a keypad and replacing a controller too.
- Water. Pull boxes fill. Conduit gets sealed, cable gets a drip loop before it enters an enclosure, and enclosures are gasketed and mounted so condensation drains rather than pools.
- Irrigation. A spray head quietly aimed at a call box will destroy it, slowly, over a season. We check the throw pattern at survey and ask for heads to be turned before we mount anything.
- Insects. Fire ants and wasps nest inside gate pedestals and operator enclosures and short things out. Sealed penetrations and the right enclosure rating matter more here than in most of the country.
- Sun. A plastic keypad in full west-facing exposure degrades. Orientation and a small hood buy years.
Inside the house: the openings actually worth controlling
Most homes out here do not need every door on a system, and we will say so. Four openings usually justify it: the garage-to-house door, a guest house or pool house, a home office or a room holding something specific, and the service entrance that staff and contractors use.
The older ranch housing stock in the Villages has a practical wrinkle. Interior doors from the 1950s and 1960s are frequently hollow-core in narrow wood jambs with no cavity for electrified hardware, and no sensible cable path without opening plaster. On those openings a good battery lock managed from the same platform is genuinely the better engineering answer, not a compromise — and we would rather tell you that than sell you a wall repair.
The value in a residence is not locking things. It is time-limited credentials, an end date you control, and a record of who came through which door. That is what converts a house with six spare keys in circulation into one where you know the answer.
Working inside an incorporated Village
Several of the Memorial Villages are separately incorporated cities with their own city halls, their own police and their own permitting — they are not the City of Houston, even though the mailing address says Houston. That matters for three parts of this work.
- Anything near the right-of-way — a gate, a pedestal, a call box at the street line — attracts more scrutiny than the same work mid-lot.
- Trenching across a front yard may have its own requirements and inspection expectations depending on where you are.
- Deed restrictions and architectural review often govern the appearance and height of a gate and anything visible from the street, independent of the city.
We confirm the current requirements for your specific address and scope during the estimate rather than assuming — the rules genuinely differ from one Village to the next, and we would rather make the call before the truck is loaded. EVOTECH IT LLC holds low-voltage licensing and insurance, carries a 5.0-star rating, and has worked Houston properties since 2004.
When this is a weekend job, and when it isn’t
Reasonable to do yourself: replacing a battery lock on an interior door, adding a video doorbell at a walk-up entry, or adding users to a gate keypad that already works.
Call somebody licensed: anything that involves the gate operator’s wiring or its safety devices; anything buried; any run leaving the building that needs surge protection and grounding; any opening where a record of entry matters; and anything on a commercial building’s exit path. The two failure modes out here are expensive — a gate that will not open for an emergency vehicle, and a storm that takes out everything on an ungrounded run — and neither shows up until the day it counts.
What sets the price out here, and what brings us back
Cost follows: driveway length and whether a conduit path already exists; whether the existing gate operator is healthy enough to keep; how many outbuildings need their own openings; trenching versus boring, and how many root zones and irrigation lines are in the way; cellular versus wired intercom; surge protection and grounding at the gate; the number of interior openings; and any Village permitting. Every item is itemized, the on-site estimate is free, and nothing gets quoted over the phone because nothing out here is standard.
Four callbacks we are asked to fix on other people’s work
- No responder plan. A gated drive with no arranged way in for fire or EMS. This is the one that matters most and gets skipped most.
- An indoor-grade keypad outdoors. It works beautifully until the first full summer.
- No surge protection on the gate run. One storm, and the damage walks back up the cable into the controller.
- Safety devices defeated to make the gate close faster. We will not do it and we will not leave it that way if we find it.

Frequently asked questions
Our gate already works with remotes. Can you add codes and phone access without replacing it?
Usually yes, and that is the normal outcome. A healthy operator keeps its board, its remotes and its safety devices; we add the entry device and a controller in front of it that closes a contact into the same input a remote uses. We check the operator’s condition and its available inputs at survey and tell you honestly if it is near the end of its life, but replacing a working operator to gain credentials is rarely necessary.
How do the fire department and EMS get through a locked gate?
They need an arranged override, and it is settled before the system goes live. Depending on the department that is a key switch at the entry, a lock box holding a key or code, or a receiver that responds to their equipment. We raise this at the estimate because it is the one part of a gated entry that cannot be added later on a bad night, and because the accepted method varies between the Villages and the City.
Our driveway is far longer than a network cable is supposed to run. What then?
Three workable answers. Fiber from the house to the gate with a small media converter at each end handles any distance you have and is immune to the surge that travels on copper. A powered midpoint in a weatherproof enclosure extends a copper run where there is power to reach. Or a cellular video intercom skips the data run entirely and only needs local power at the gate. We measure the actual route on the estimate visit and price the one that fits.
Can we give the housekeeper and the pool service their own access?
Yes, and it is the most common reason people here call. Each person or vendor gets their own credential or code, restricted to the days and hours you choose, with an end date if the arrangement is temporary. When somebody stops working for you, that single credential is removed in seconds without affecting anybody else, and the log shows exactly when they last came through.
We have an old intercom handset in the kitchen. Does it have to go?
Not necessarily. Some older wired station systems can stay in service alongside a new gate entry, which suits households that like a physical handset by the back door. Whether yours can be kept depends on what is behind the wall, and we check it during the survey. If it cannot be integrated cleanly we will say so rather than leaving you with a device that half works.
We are in an office suite near Memorial City, not a house. Do you do that too?
Yes, but it is a different conversation and a different scope. In a leased suite the landlord generally controls the lobby, stair and garage doors and your suite door is the one you can act on, so the first step is confirming in writing what your lease and the building engineer allow. The gate, trenching and weather sections of this page will not apply to you; the door hardware, credential and egress considerations still will.
