The gate opens for the resident's car.
The car's tag is read, the gate opens and closes right behind it. Nobody gets out on the sidewalk to look for the remote.
Access control
Every Person in the Right Place, at the Right Time.
The door opens for the right people, at the agreed time, and keeps a record. No copied keys, no paper lists, no line at the entrance.
In a few words
Access control is the system that decides who enters, where and at what time, and logs every passage. People identify themselves with a card, tag, phone, password, QR code, fingerprint or face, at doors, gates and turnstiles. ARX designs, installs and maintains it, including releasing the exits in an emergency.

In your day
You use it every day and almost never notice.
When access is done right, nobody thinks about doors. Those who may pass, pass. Those who may not, do not. And the record exists on the day someone asks.
The visitor comes in with the invitation.
They received a QR code along with the meeting invitation. They hold it up to the reader and walk in. It is valid only for today, only for that door.
The stockroom door knows who came in.
Only management and the stock clerk can open it. If merchandise is missing from inventory, there is a time and a name to start the conversation.
The store locks itself and nobody is trapped inside.
At the set time, the door locks for those outside. From the inside, exit remains free, as it should be.
When it fails
That's when everyone notices.
The three problems we find most often, where they come from and how we avoid them.
The former employee still gets in.
Where it comes fromThe registry is never reviewed. Cards, passwords and remotes of people who have already left remain valid, and nobody knows how many exist.
How ARX avoids itEach person has their own credential, with a profile and schedule. We leave the offboarding procedure ready: one action blocks the person at every door.
In a power failure, the door locks everyone inside.
Where it comes fromThe lock was chosen thinking only about who tries to come in. Nobody asked what happens on the way out when the power fails or the fire alarm sounds.
How ARX avoids itA door on an escape route releases the exit without power and on the fire alarm, following Fire Department rules. We test this at handover, with you present.
The face became the only way in.
Where it comes fromThe system was sold on novelty. Anyone who does not want to register their face, or is not recognized that day, stays outside.
How ARX avoids itThe face is an option, never the only one. We define the purpose, the notice and who keeps the registry, and we keep a card, tag or password for anyone who prefers it.
How ARX does it
Simple for you. Rigorous on the inside.
We map doors and people
Which doors, who passes through each one and at what times. Residents, employees, visitors and service providers have different needs.
You receive: the map of doors, profiles and schedules.
We choose the credential by risk
A stockroom door does not call for the same thing as an office door. For each one, we define the way in. Emergency exits are handled separately.
You receive: the way in for each door, with the reason.
We install with backup power
Readers, locks and controllers sit on a separate network and run on battery. A controlled door that shuts off along with the lights controls nothing.
You receive: the doors installed and the administrator access.
We test and teach the routine
We simulate a denied badge, a forced door, a power failure and a fire alarm. Then we show how to enroll, block and check the history.
You receive: the test results and the enrollment procedure.
Equipment
What goes into your project.
Examples of what we install. The final choice depends on your space and your budget.
Opens the door with a card, tag or phone. Sits beside the door, almost invisible.
Recognizes the face, shows who has arrived and lets you answer from anywhere.
For front desks and service entrances: code, call and remote opening.
Reader, controller and credentials: what you need to control the first doors.
You see and talk to whoever rang, from your phone, before opening.
Panel for the front desk, the door and the apartment, with video and opening through the app.
Doors, readers and intercoms. Cameras, recording and video intelligence.Brands
The right brand is the one that fits your project and your budget.
UbiquitiWhen you want door, camera and network on the same dashboard. People enter with a phone, card, password or face, the intercom rings on your phone and every opening is recorded with the image of who passed.
HikvisionWhen the project is large or has a bit of everything. The line goes from the face reader to the turnstile and the intercom for the whole building, and a single platform brings together doors, intercoms, visitors and cameras.
IntelbrasWhen you are looking for something simple and direct. A digital lock or face reader, card and password for a door, a gate or a small entrance, from a Brazilian manufacturer, with parts and service that are easy to find.
AxisWhen the requirement is the highest. Networked controllers that store the credentials at the door itself, video intercoms, and the car's license plate and the visitor's QR code as credentials. It works with systems from other manufacturers and is built to last many years.
What hardly anyone tells you
Before asking for a quote, it's worth knowing.
A standard card can be copied.
Older cards and key fobs have no protection: a simple device reads and duplicates them. There are encrypted credentials, much harder to copy. Before you sign, ask which card technology is in the proposal.
Every electric lock has a side when the power goes out.
Without power, it either locks or releases. On an escape route, it has to release. This choice is made door by door and should be written in the proposal. If it is not, ask.
The registry is yours, not the installer's.
Names, photos and fingerprints are stored somewhere. Ask where, who has the administrator password and how the records of people who left are deleted. With equipment provided on loan, this may stay with the supplier.
Questions and answers
Which is the most secure: card, password, biometrics or face?
It depends on the door. A password can be passed along and a card can be lent. Fingerprint and face are personal, but call for more care with privacy. On important doors, it is common to combine two methods, such as card and password. We define it door by door.
If the power goes out, does the door open or stay locked?
That is decided in the project, door by door. Emergency exits always release. Security doors can stay locked from the outside, with a battery keeping the system on. What cannot happen is finding out the behavior on the day of the blackout.
Can I require facial recognition from everyone?
In our projects, the face is never the only option. Under LGPD (Brazil's data protection law), it is sensitive personal data. You need a clear purpose, you must notify people, protect the registry and offer another means of entry, such as a card, tag or password, to anyone who does not want to use it.
How does entry work for visitors and service providers?
The visitor receives a temporary credential, such as a QR code or a password, valid only for the agreed day, time and doors. After that, it stops working. Yesterday's service provider does not get in today, and everything is logged.
Can the entrance be modernized without replacing gates and turnstiles?
In many cases, yes. Gates, turnstiles and locks in good condition usually accept new readers and controllers. During the visit, we assess what can stay and what needs replacing. It is a typical retrofit project.
Does ARX install access control in any city?
Installation, with an on-site team, is done in the State of São Paulo: the capital, the interior and the coast. Design, consulting and retrofit design, on the other hand, serve all of Brazil.
