Access Control Installation in Katy & Houston, TX

Professional access control installation for doors, gates and whole buildings

Access control replaces keys with credentials. Instead of cutting brass keys that get copied, lost and never returned, you decide electronically who can open which door, on which days and hours, and you get a time-stamped record of every entry. EVOTECH IT LLC designs, installs and programs complete access control systems across the Katy and Houston area — from a single stockroom or front office door, to a multi-door commercial building with dozens of readers tied to one management platform you can run from your phone.

We are a licensed and insured low-voltage contractor with more than 20 years of hands-on experience and a 5.0-star rating. That matters here more than almost anywhere else in security work, because a badly installed access control door is not just an inconvenience — it can be a life-safety and fire-code violation. A door that traps people inside during a power failure, a magnetic lock with no way to exit, or a system that lets a terminated employee back in next week are the kinds of mistakes we are called to fix. We install so those problems never happen, and we hand you a system you actually understand.

Below is a straight, no-jargon guide to how these systems actually work, the choices that decide your security and your budget, and exactly what our installation includes — so you can make a confident decision whether you hire us or not.

Keycards, fobs, PIN codes, mobile credentials and biometrics

The credential is what a person presents at the door to prove they are allowed in. Choosing the right one is the first real decision, because it drives your day-to-day security, how easy the system is to manage, and how much it costs to add or remove a person. Here are the options we install and where each one earns its place.

Proximity cards and key fobs (125 kHz)

The classic thin white card or the plastic fob on a keyring. You tap or wave it near the reader. They are inexpensive and familiar, but the older 125 kHz proximity format is easy to clone with a cheap copier bought online — a real weakness if your doors protect anything valuable. We still install prox where budget and low risk justify it, but we tell you honestly what it does and does not protect against.

Encrypted smart cards (13.56 MHz)

Modern smart credentials such as MIFARE DESFire use encryption and mutual authentication, so they cannot be trivially copied the way old prox cards can. For any new business system this is our default recommendation — the small extra cost per card buys a meaningful jump in security. Smart cards can also carry more than one function, so the same badge can work for access, time-and-attendance and a printed photo ID.

PIN keypads

A keypad lets people enter a numeric code instead of carrying anything. It is convenient and cheap for low-traffic or lower-security doors, but codes get shared, shoulder-surfed and never really forgotten, so a keypad alone is the weakest option. Where security matters we use a keypad as a second factor — card plus PIN — so a found or cloned card is useless without the code.

Mobile credentials (phone as your key)

The fastest-growing option: the credential lives in an app on the user’s phone and unlocks the door over Bluetooth or NFC. Nothing to lose, nothing to hand back, and you can issue or revoke a person in seconds from anywhere without meeting them to collect a card. Great for staff turnover, contractors and property managers. Most platforms charge a small per-credential subscription, which we lay out plainly in the quote.

Biometrics (fingerprint and face)

Fingerprint and facial readers tie entry to the person, not a card that can be handed to someone else. They suit high-security rooms — server rooms, pharmacies, cash offices. Because biometrics capture sensitive personal data, they carry privacy obligations, so we deploy them where the security need is real and pair them with a card or PIN fallback for reliability.

Many sites mix credentials — smart cards for staff, mobile for managers, a keypad on the back door — and a good system runs them all from one database. We help you match each door to the right credential instead of forcing one choice on the whole building.

Electric strikes, magnetic locks and electrified door hardware

The reader decides whether to unlock; the electric lock is what actually holds the door. Picking the wrong lock for an opening is the single most common way a job goes wrong, so this is worth understanding.

Electric strikes

An electric strike replaces the metal strike plate the latch drops into. Your existing lever or lock stays on the door; the strike simply releases the latch when access is granted. It is the clean, affordable choice for most standard commercial doors and it preserves free mechanical exit from inside — you can always turn the lever and walk out. Strikes come in fail-secure and fail-safe versions (explained below).

Magnetic locks (maglocks)

A maglock is a powerful electromagnet on the frame and a steel plate on the door; energize it and it holds with 600 to 1,200 pounds of force. Maglocks are ideal for glass storefront doors, gates and openings with no room for a strike. But a maglock has no mechanical override — it is always fail-safe (it lets go when power is cut), and fire and building codes require additional guaranteed ways out, such as a request-to-exit sensor and a push-to-exit button, plus automatic release on the fire alarm. Installed correctly, maglocks are excellent; installed carelessly, they are a code violation waiting to happen.

Electrified locksets and panic hardware

For heavier or higher-security openings we install electrified mortise locksets and electric latch retraction on panic bars (crash bars), so an exit device on a fire door can be released electronically while still allowing instant push-to-exit. This hardware costs more but is the correct answer for main entrances, stairwells and rated fire doors.

Fail-safe vs. fail-secure — the concept that keeps you legal

Fail-secure means the door stays locked when power is lost — it protects the opening, and you still exit freely from inside by hand. Fail-safe means the door unlocks when power is lost — required where an opening must never trap anyone. The right choice depends on the door’s role and the egress path, and it is not a preference — it is dictated by life-safety code. We spec it per opening and document why.

Anatomy of a controlled door: reader, controller, lock, REX and sensors

Every controlled opening, whether it is one door or one of fifty, is built from the same handful of parts. Understanding them makes the quote and the system make sense.

• Credential reader — mounted on the unsecured side, it reads the card, fob, PIN or phone and passes the credential to the controller.
• Door controller / access panel — the brain, mounted on the secure side. It holds the list of who is allowed, checks the credential against schedules and permissions, and tells the lock to release. It keeps working and logging even if the network or internet goes down.
• Electric lock — the strike, maglock or electrified hardware that physically secures the door.
• Request-to-exit (REX) — a motion sensor or push button that recognizes someone leaving, so a normal exit does not trigger a forced-door alarm and, on a maglock, releases the door to let them out.
• Door position switch (DPS) — a magnetic contact that tells the system whether the door is open or closed, so it can detect a door propped open too long or forced open.
• Power supply with battery backup — regulated power for the locks and controller, with a battery so the system rides through short outages and fails to the safe state on a long one.
• Management software — the platform, cloud or on-premise, where you add people, set schedules, run reports and lock the building down.

Here is the sequence when someone opens a controlled door:

1. The person presents a credential at the reader.
2. The controller checks it against the permission list and the time schedule.
3. If allowed, the controller releases the lock for a set number of seconds.
4. The door-position switch confirms the door opened and then closed and relocked.
5. The event — who, which door, exact time, granted or denied — is written to the log.
6. Leaving, the REX device releases the door and records a clean exit, no alarm.

Free egress, request-to-exit and fire-code compliance

This is the part cheap installers skip and the part we will not. In the United States, people must be able to get out of a building freely in an emergency — access control locks the way in, never the way out. Every system we install is designed around guaranteed egress first, security second.

Request-to-exit, done right

Free exit is provided by request-to-exit devices: a motion sensor mounted above the door that senses a person approaching from inside, a clearly marked push-to-exit button, or a switch built into the door’s own lever or panic bar. On a fail-secure strike you can always turn the handle; on a maglock, the REX is what physically drops the magnet so a person is never held in.

Fire-alarm release

Any magnetically locked door in a path of egress is wired to release automatically when the fire alarm sounds or power is lost. We coordinate this tie-in so the access control and the life-safety system agree — a step DIY and handyman installs routinely miss.

Delayed egress, where it is legal

Some retail and healthcare settings use special delayed-egress hardware that holds a door for a code-limited 15 seconds to deter theft or wandering while still guaranteeing exit. It is tightly regulated, so we install it only where it is permitted and always with the required signage and alarm.

We never trade a person’s ability to leave for a little more security, and we document the egress design so an inspector, a fire marshal or your insurer can see it was done correctly.

From a single door to a multi-door, multi-site system

Access control scales smoothly, and the right size for you depends on how many openings you need to control and how you want to manage them.

Single-door and standalone systems

For one or two doors — a stockroom, a server closet, a small office — a standalone controller at the door, or an all-in-one smart lock with a reader, is often the most cost-effective answer. You still get credentials, schedules and a basic log without a full networked head-end.

Networked multi-door systems

Once you have several doors, a networked system pays for itself. Multi-door panels (commonly 2, 4, 8 or 16 doors each) tie every reader back to one database, so you add a new hire once and they work at every door they should. You get:

• Schedules — front doors auto-unlock during business hours and lock after, with holiday calendars.
• Access groups — the warehouse team opens the dock, the office team does not; managers open everything.
• Audit trail — a searchable record of who entered which door and when, invaluable for disputes, shrinkage and HR.
• Lockdown — secure every door instantly from a button, a phone or a badge in an emergency.

Multiple buildings and sites

Growing organizations manage many doors across several addresses from a single platform, with different administrators for different sites. We design the wiring, panels and network so today’s single building can grow into tomorrow’s campus without ripping anything out.

Cloud-managed vs. on-premise access control

Where the ‘brain’ and your management software live is a real decision with trade-offs. Here is the honest comparison we give every customer.

Cloud management is the easy button for most businesses: nothing to maintain, add or remove a person from your phone, and manage several locations from one screen. On-premise wins when you prefer to own everything outright with no recurring bill, or when policy requires your access data to stay in the building. Both keep working at the door if the internet drops, because the controllers make the decision locally — the cloud is for management, not for unlocking. We install both and will tell you which genuinely fits your operation. Many clients pair either choice with our commercial IT solutions so the network behind it is solid.

Integrating access control with cameras, alarms and intercoms

Access control is most powerful when it does not stand alone. Tying it to your other systems turns a set of locks into a single, searchable security picture.

Security cameras

Link each door event to video so a badge swipe is stamped on the exact camera clip — you see the person, not just the credential, which instantly catches a shared or stolen card. We design this alongside our security camera installation so the two systems speak the same language.

Alarm systems

Access control can arm and disarm your intrusion alarm from a valid badge, and a forced or held-open door can trigger the alarm and a lockdown. One credential to disarm and enter means no more shared keypad codes on a sticky note.

Intercoms and visitor entry

For visitors without a credential, an intercom or video entry station lets staff see and speak to whoever is at the door and release it remotely — ideal for reception, gated lobbies and after-hours deliveries. See our intercom installation page.

Gates and license-plate reading

At a driveway or parking gate, access control pairs with plate-reading cameras so a known vehicle opens the gate automatically and unknown plates are logged. That is covered on our gate & license-plate camera page.

What a professional EVOTECH access control installation includes

‘Installation’ should mean a complete, code-compliant, documented system you can actually run — not a reader stuck to a wall. Every EVOTECH access control project includes:

• On-site survey & design. We walk every opening, check the door hardware and egress path, choose the correct lock and credential for each, and lay out controllers, power and cable runs before we quote — so there are no surprises.
• Correct lock selection per door. Fail-safe or fail-secure, strike or maglock or electrified hardware, matched to the door’s role and life-safety code, and documented.
• Clean, concealed low-voltage cabling. Proper rated cable fished through walls, ceilings and attics to each reader, lock, REX and door contact — not surface wire stapled across your frames.
• Controllers, power and battery backup. We mount and wire the panels, regulated power supplies and batteries so the system rides through outages and fails to the safe state.
• Egress & fire-alarm coordination. Request-to-exit on every controlled door and automatic release of magnetically locked egress doors on the fire alarm.
• Software setup & enrollment. We stand up the cloud or on-premise platform, enroll your people and credentials, build schedules and access groups, and set up lockdown.
• Testing & training. We test every door granted and denied, day and night, verify the log and remote access, and train your team to add and remove people themselves.

Our installation process, step by step

1. Free on-site estimate. We visit, learn how your doors are used and who needs to go where, survey every opening and egress path, and give you a clear written scope and quote. No pressure and no invented numbers.
2. System design. We finalize credential type, lock hardware per door, controllers, and cloud or on-premise management, and confirm the egress and fire-code approach with you.
3. Cabling & rough-in. We run and conceal the low-voltage cable to every reader, lock, REX and door contact, working around your business hours.
4. Hardware install. Readers, locks, controllers, power supplies and door contacts go in, wired neatly and labeled.
5. Program, test & tune. We enroll people and credentials, build schedules and groups, and test every door — granted, denied, exit, forced, held-open and fire-alarm release.
6. Train & hand off. We show your team how to add and remove users, pull reports and run a lockdown, and leave you documentation.
7. Local support. We are local — if something needs adjusting later, we are a call away at (832) 359-2425.

Residential gates, homes and commercial systems

Homes and businesses share the same technology but solve different problems, and designing them the same way is a common mistake.

Homes and residential gates

At a home the usual goals are a driveway or pedestrian gate that opens from a keypad, fob or phone, a controlled door on a home office, garage or ADU, and letting family and trusted visitors in without handing out keys. A gate operator pairs naturally with plate-reading cameras — see our gate & license-plate camera page. For a single entry door a good smart lock may be enough; when you want schedules, multiple credentials and a real log, a small access control system is the better tool, and we will tell you honestly which one fits.

Commercial buildings

Businesses add front and back entrances, stockrooms, server rooms, offices, loading docks and cash areas — each with different people allowed at different times. Retention of the log is longer for liability and HR, access is role-based, and doors often need to integrate with cameras and alarms. We design commercial systems to hold up under real use and inspection: correct egress on every door, encrypted credentials, and a clean audit trail.

Built for Katy and Houston

We install throughout Katy, Houston, Sugar Land, Richmond, Fulshear, Cypress and the surrounding communities, for medical suites, offices, warehouses, retail and multi-tenant buildings. Texas heat, sun and Gulf-coast storms are hard on exterior readers, gate hardware and cabling, so we use outdoor-rated equipment, add surge protection and weather-seal every exterior device. Being local also means service is a short drive away — not a support ticket to another state.

Access control mistakes that cause lockouts, break-ins and code violations

Almost every failed access control job repeats one of these mistakes. Knowing them helps you judge any installer — including us.

1. Wrong fail-safe / fail-secure choice. Get this backwards and you either trap people inside or leave a door unlocked whenever the power blinks. We spec it per opening against the egress path and code.
2. Maglock with no proper egress. A magnetic lock without a request-to-exit device, push-to-exit button and fire-alarm release is a serious life-safety violation. We never install one without them.
3. No fire-alarm coordination. Egress doors that do not release on the alarm can fail inspection and endanger people. We coordinate the tie-in every time.
4. Cheap clonable prox credentials. Old 125 kHz cards can be copied in seconds. Where security matters we use encrypted smart cards, mobile credentials or card-plus-PIN.
5. No plan for lost cards and departing staff. A system nobody knows how to update lets old credentials keep working. We train you to revoke a person in seconds.
6. Ignoring tailgating. One badge, several people slipping through. Where it matters we design for it with door contacts, anti-passback rules and camera verification.
7. No battery backup. A system that dies with the power is either a lockout or a wide-open door. We back up power on every install.

What affects the cost of an access control system

Every building is different, so we give real, itemized quotes after a free on-site look rather than a fake ‘starting at’ number. The honest drivers of cost are:

• Number of doors. The controlled-opening count is the biggest single factor — each door needs a reader, a lock, a REX, a contact and wiring.
• Lock hardware per door. A simple electric strike is far cheaper than electrified panic hardware or a maglock package with all its egress devices.
• Credential type. Basic prox cards cost little; encrypted smart cards, biometric readers and mobile credentials (with their per-user subscription) cost more and secure more.
• Cloud vs. on-premise. Cloud adds a recurring subscription; on-premise adds up-front hardware you own outright.
• Cable runs and door prep. Long, concealed runs, masonry, two-story pulls and doors that need hardware modification take more labor and materials.
• Integrations. Tying access control into cameras, alarms, intercoms or gates adds capability and some cost.

Our estimate is itemized so you can see exactly what each part costs and adjust the scope to your budget. The on-site estimate fee, when one applies, is credited toward your project. To get real numbers for your building, request a free on-site estimate or call (832) 359-2425.
