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.

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. !!
