Ron is always willing to go above and beyond for us both in our home and business systems. He installed security cameras for us and took a lot of time to make sure they were the right fit for what we needed and that we were pleased. We HIGHLY recommend First Defense Alarms!

Amanda Arthur

Ron was very easy accessible, I texted him and he promptly responded to me and was out here the next day. When he came out to install the alarm he was very informative and made sure everything worked properly.

First Defense automated my home and I have been so pleased! I have loved how easy everything is and the installation tech was so reassuring. I'm a single woman living in Mid-Town Tulsa and I feel so much safer at night now. The reminders for me to set the alarm, being able to adjust the thermostat from the bed and notices about open doors have been a game changer. Why did I wait so long? How did I live without this before?


We had an ADT system installed in our home and after three years of "non-service", we switched to First Defense. We had no idea how good their service was until we were about to leave for vacation. We were leaving for Florida Sunday evening when we realized there was a problem with one of our doors. The weekend service technician was on a call and could not make it to our house in time. The owner of First Defense came to our house on a Sunday, fixed our door and we made our flight. Thanks
