Detect Threats, Notify Everyone, and Manage Incidents in Real Time

True Proactive Security

Detect Threats

InformaCast emergency notifications can be triggered manually or automatically using access control panels, panic buttons, fire alarms, or video analytics. These early warning capabilities are critical for agencies and schools, enabling rapid communication from the moment a threat is identified. Our mass notification systems integrate with existing infrastructure to initiate alerts in seconds, giving teams the time they need to respond effectively.

In high-traffic environments like Fort Lauderdale hospitals, Boca Raton campuses, and West Palm Beach office towers, fast and clear alerts matter. InformaCast delivers emergency notifications across multiple channels: mobile apps, PA systems, signage, desktops, tablets, and radios, ensuring critical messages are received, even in loud or distracted settings.

No more NVR!

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.
Sharon Casha
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!!
Faye Kotler
They are always helpful on the phone and good about getting a tech out quickly when necessary.

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!
LOURDES ARAGON
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.
Leslie Srolovits
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.
John Sexton
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.
Gianella Diaz
Ricky Zalewski at AT&I is very helpful and extremely pleasant to deal with.
Jessica O'Connor
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!
Jonathan D. Rausch
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. !!
Evernia Place Manager
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.

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.
