A history of innovation and expertise
Our Beginnings
More than 55 years ago, with the help of a police officer, SONITROL was founded with the goal of reducing false alarms and increasing criminal apprehensions.
In 1960, Robert Baxter, of Anderson Indiana, installed microphones within the walls of a building to listen for termites and pinpoint their location. Many sound-related inventions later, Baxter met Al Cronk, a local police officer, in 1963.
Frustrated with the current systems that seemed to let the perpetrators get away, Cronk joined with Baxter to develop ideas for a new alarm company. Baxter responded with the audio sensor, and so SONITROL was born as a security company in 1964.
