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.

Nicole Morales
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.
Guy Davis
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!
Francine Valentino
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!

  • Old, clunky software takes up too much of your time.
  • Stand-alone systems don’t provide much value.
  • Non-mobile access control is no longer considered an amenity.
