Security Service with a Sound Advantage:
50 Years of Protection

Security Service with a Sound Advantage: 50 Years of Protection

Started right here in Indiana, Sonitrol has been serving Hoosiers for more than 50 years. In that time, we’ve grown to an organization of 150 offices in the United States and Canada, all developed with the same fundamental principles of providing local security service powered by the unique audio verification system that only Sonitrol offers. For the last several years, Sonitrol of Indianapolis ranked as one of the Top 100 Security Companies in the Country, per SDM, a leading industry magazine. We’re quite proud of this accomplishment, as it ranks our local office and monitoring station among industry giants (without the same local service offered by Sonitrol).


Sonitrol's roots date back to the early 1960's in Anderson, Indiana. A veteran police officer, Al Cronk, wanted to develop a security system that would accomplish two things; reduce false alarms and catch burglars. Mr. Cronk then partnered with a local inventor in the Anderson area who had created the Sonitrol intrusion security system to enhance his pest control business. This technology has evolved to the high tech security system used in businesses across the country today. In the last 35 years, more than 174,000 apprehensions have been made nationally thanks to the Sonitrol intrusion security system.


Our background and experience has propelled Sonitrol as a leader in providing security service to Central Indiana schools, places of worship, warehouses, office buildings, small businesses, apartment complexes, multi-use buildings, construction sites, and many industries not included in this list. Whatever field you work in, we’ve likely designed an integrated security system to address the unique needs of your industry. Sonitrol is the go-to company for integrated, state-of-the-art solutions for intrusion security, video equipment, access control systems and fire protection services, all backed with professional monitoring by experienced, trained personnel. Our offices, service technicians and central station operate out of downtown Indianapolis and are all Sonitrol employees – no subcontractors or affiliate employees, just Hoosiers protecting Hoosiers.


Sonitrol celebrates more than 35 years of providing corporate security solutions to the greater Indianapolis area. Our UL-approved monitoring station in situated in downtown Indianapolis and is staffed with trained dispatchers around-the-clock to serve the needs of Sonitrol customers. We’re one of only a few security companies that operate a local monitoring center and are the only provider in the country that offers a security system utilizing verified technology. These key elements contribute to Sonitrol having the lowest false alarm rate and highest apprehension rate in the business.
