Comments: They really took the time to figure out the old system and were able to use many parts of it. The whole system now works exactly the I expect an alarm system to work. Great peace of mind.

Comments: Quick response; very professional. They got the job done merging an old hardwired ADT system with wireless on the windows that were replaced in our home recently.


Alert Security has installed Surviellance Cameras and ADT Alarms in over 20 Freddy's Frozen Custard & Steakburgers in 5 states. An additional 6 new restaurants will be opening this year with our cameras and alarms keeping them safe.
