Access For The Modern World

Commercial Access Control Systems to Protect Your People and Property in Florida

Protect your team, tenants, and operations with commercial access control systems in Florida engineered for real-world commercial environments. AT&I Systems designs, installs, and supports cloud-managed and keyless-entry solutions that combine mobile credentials, biometric options, and centralized administration. Our systems are built to scale across statewide portfolios and high-traffic properties throughout South Florida.

We offer Avigilon Alta Access (Formerly Openpath) as part of an engineered access control architecture, prioritizing reliable door performance, credential governance, and clean integrations across your security stack. Instead of “features-first,” our approach centers on how the system will be installed, commissioned, and managed day to day across your doors, buildings, and sites. Common capabilities include:

  • Mobile credentials and remote unlock
  • Keycard, fob, and smart device compatibility
  • Encrypted communications and secure cloud administration
  • Guest/visitor workflows and scheduled access
  • Integration pathways for video surveillance and intercom systems

Biometric Access Control & Keyless Entry Systems

Biometric access control is the latest trend in keyless entry systems in Florida. From high-security zones to fast-moving lobbies, technologies such as fingerprint, facial recognition, and iris scanning provide fast, secure credentialing without cards or PINs. In South Florida, these deployments are common in healthcare campuses, multifamily communities, hospitality-adjacent properties, and Class A commercial buildings where traffic flow and access exceptions are part of daily operations.

Biometrics are often used for highly restricted areas, but they can also be effective in high-traffic areas where speed matters, so long as the system is designed with appropriate policies, backup credential paths, and clear privacy/administration controls.

How does access control fit in your business?

Openpath for existing systems

Your existing system

Antiquated software and easily bypassed credentials can create risk and add workload, especially when multiple stakeholders need access, changes happen frequently, and audits are required. Common issues we see include:

  • Wiegand 26-bit credentials can easily be copied.
  • Legacy software that slows down routine administration.
  • Stand-alone systems that don’t integrate into broader security operations.
  • Lack of modern mobile or cloud capabilities.

Why Upgrade?

The modern world is constantly changing, and an old access control system could be holding back your community, workplace, or property. A cloud-based access control system could provide the following:

  • An improved access-control experience on a smartphone reduces the risk of credentials falling into the wrong hands.
  • Stay one step ahead with future-proof IoT hardware and end-to-end cloud management software that never compromises on security.
  • Increased ROI with cloud updates to your devices' software/firmware

  • Cloud updates to the software and firmware protect your ROI.

Intuitive hardware

The best access control hardware is the kind your users don’t have to think about. We help you match door devices to real usage: lobby throughput, ADA considerations, perimeter doors, tenant spaces, secured interior zones, and after-hours access. When appropriate, we build in practical redundancy (alternative credentials, mechanical considerations where applicable, and clear exception handling) so day-to-day operations don’t stall when conditions change.

Integrations

Access control is rarely isolated, especially on campuses, gated properties, and mixed-use sites. AT&I Systems designs integrations that support how security and operations actually run, including:

Fantastic service! James took my call and coordinated everything needed for our new gate system on the first call. He scheduled the install and the techs were on site bright and early. The techs Mark and Josh did an outstanding job on the install. From start to finish, I could not be happier with the experience.

It was approx 15 years ago was I first used AT&I at a property I worked at in Deerfield Beach. At the time my experience with most gate companies were far from favorable, but with AT&I I was amazed by their honesty. They are a great consistent group of decent honest people that do-good work period! I value and have trusted their input and service along the way, and will continue to do so, as they have yet to fail me. Thank you, AT&I Systems!!

They are always helpful on the phone and good about getting a tech out quickly when necessary.
Great bunch of folks to work with, we submitted a work request on Wednesday, and they were here on Thursday diagnosing the problem. Service tech was very knowledgeable and professional. We look forward to a long relationship with AT&I......Thanks
All the techs are great. Mark is outstanding . He can represent my company anytime. You, lucky to have him. 👍👍👍👍👍. Rich Fallon
ATI Security Systems is always prompt with service and their response time. Anytime we call or email for service, they usually send out a tech same day, when its possible. Our company has used them for our community gate repairs for years!
AT&I installed a new parking access system at an office building we mange in Doral. From start to finish it has been a great experience. They are prompt in replying, they show up when scheduled. Oscar, Brett and Dave are a great team and we are happy we selected AT&I for our new access system.
AT&I staff are real professionals. They held our hand during the implementation of GateKey and OpenPath. In our development, we love the simplicity of the GateKey entry system - it’s simple and intuitive to use. The OpenPath system allows our snowflakes to open the gates while driving a temporary rental car or as a passenger in someone else’s car. Great products and great team.

I have worked with James at ATI for my condo association with multiple gates and cameras. Before ATI, we were a mess. After suggested upgrades and replacements, we are finally running 24/7 with few glitches now in community. The problems we have had over past year were addressed promptly and properly. I have no doubt that no other company could do a better job.
Ricky Zalewski at AT&I is very helpful and extremely pleasant to deal with.
I have been working with AT&I Systems for several months now. They are very quick in responding to our access gate service calls. We will hopefully be contracting them to do all of our security cameras as well! I would highly recommend them. Brett W is awesome!
ATI and there staff are first class. They solve problems and give solutions. I’ve been a BOD and a licensed Property Manager. I’ve hired them at multiple properties and they’ve done an excellent job. I wouldn’t highly recommend Oscar Jon and Ricky for your South Florida gate needs. When the gate goes down or the call box has an issue just call or e-mail them for assistance. Bravo ATI. !!
Great Company. Troy Hildebrant was AMAZING. He came out and trouble shot our issue and had it fixed in no time!! Very knowledgeable, professional, dependable and kind. Would definitely recommend this company.

Such a great company. Always available when we need them here at Parc3400 to assist. Very friendly technicians and also very knowledgeable about the issues and how to fix them. Would recommend this company to any communities in the area.
10/10 recommend this company. They offer great products. The staff is very professional to work with. They are responsive and have reliable service. The Cellgate system is easy to use which is a major plus since I use it everyday. I love it.

I have been dong business with ATI for years. Pricing and service are fantastic. Had an issue with alarm and security gates last week. Service tech's were out the same day and resolved all issues at a fair price. Would not use any other company!
It was a pleasure to do business with AT&I security systems. We called them in the morning and our gate was fixed in the same day. They have the nicest staff and their sales team is always eager to help. Their camera quality is superb and their gate systems are truly the best! Thank you Oscar and team!
