We took bids from three other non-local security companies when we were looking for a security system for our warehouse. Stay local, OSI had more knowledge of the products and trained us well.
After my father passed away, my mom began to live alone. We got her the medical alert button and it has saved her life more than once. Thanks to John and OSI.
Security for under a dollar a day, who would have thought.
We needed security cameras, a front door keypad. It was all installed professionally. Would use OSI again and again.
We Set the Alarm off at the house just to see the response time. Under 30 seconds. That's awesome response.
The bid was on time. The work was finished early. The system is wonderful. OSI you rock.
Now when we go out of town, I watch the security cameras on my phone. I love that feeling of security.
We use OSI for our home owners association. They watch everything closely and let you know if something looks wrong. Great work.
Every time our company has a tent sale, OSI provides on site security. We have never lost a thing.
I like the fact John is a veteran and he's local and his company appreciates your business. Use OSI.
