About SDG Security

At SDG Security we've been protecting loved ones, homes and businesses since 1986.

We were originally founded as Sound Design Group by Bruce Reedy and Steve McCullum, a team that had worked together for more than 10 years in the electronics industry.

Since its inception, SDG Security has specialized in custom designed security, communications, and sound systems. Due to the rapid growth of our monitored security systems we soon established our own central station staffed with SDG personnel.

Our team of dedicated employees totals 14. These are the smiling faces that serve you every day!

Read What Our Customers Are Saying About Us:

"SDG Security smoke sensors saved my life. When my fish tank pump caught fire, the sensors sounded the siren and SDG Security dispatched the fire department. I may have not heard a standard, battery operated sensor on that level. I owe my life to SDG Security."
- Tim in Columbus

"My father lives alone and has a SDG Security Medical System. I am confident that he is safe and sound with his wrist alert system. SDG Security came out to explain the system to dad and I know that he feels safe, yet maintains his independence, which is very important to him."
- Judy in Springfield

"My business has had SDG Security systems for almost 25 years. Every time there is a need for service they are fast to respond, fast to resolve the issue, and very reasonably priced. I rest assured each day that my business is in good hands with SDG Security."
- Mike in Columbus
