We are experts at assessing your school's vulnerabilities and recommending appropriate, cost-effective solutions.

RETAIL

Sonitrol is a leader in modular, scalable security solutions that minimize shrinkage and drive a solid return on investment. Our state-of-the art technology includes verified audio & video intrusion detection, verified digital video surveillance, access control and fire detection. Our alarm systems can also be integrated with HVAC and other building systems.

COMMERCIAL/OFFICE

Whether you run a small shop or a booming operation, your business is vulnerable on a variety of fronts. Burglars looking for cash or computer equipment aren't the only threat. Employee theft is a growing issue, and it costs American businesses billions of dollars each year. In the United States alone, more than 5,000 cases of workplace violence are reported every day.

HEALTHCARE

High public traffic and inventories of drugs put hospitals and other healthcare facilities at risk of internal and external theft, and burglary. Today, stringent HIPAA guidelines make security even more critical. Sonitrol offers solutions that help healthcare facilities comply with HIPAA regulations and protect their property, assets, employees and patients.

PAWN & GUN SHOPS

Sonitrol helps keep guns off the streets as Pawn and Gun shops are prime targets for thieves. Criminals know pawn shops have a high concentration of valuable merchandise, including guns, that can be quickly converted into cash, and they can get in and out before the police have a chance to arrive. With Sonitrol, your chances are better at apprehending these types of criminals.

CONSTRUCTION SITES

Sonitrol builds a better security system. Whether you're starting from the ground up or renovating an existing building, you're vulnerable to break-ins, vandalism, fire and other threats. Sonitrol provides integrated security solutions for construction sites nationwide. We have a program specifically tailored to meet the unique needs of new buildings.

Our unique verified audio & video detection and verified video deliver comprehensive projection for your dealership. Whether you have a single dealership or a regional chain, our modular, scalable designs make it easy protect your business today and meet your needs.

Cash is the classic temptation causing robberies, burglaries, vandalism and false ATM transactions. Sonitrol offers a program specifically tailored to meet your needs. Based on our proprietary verified audio & video detection, a Sonitrol system delivers effective protection with low false alarms, lightning-quick police response, and the highest apprehension rate in the industry.

FAITH-BASED

Sonitrol can help protect your people and your property. Your organization does tremendous good for the community you serve. A burglary, a fire, even a false accusation could seriously threaten your ability to carry out your mission. Sonitrol provides integrated security solutions specifically tailored to the needs of faith-based and other non-profit organizations. 

GOVERNMENT

In this day and age, security is more critical than ever. Sonitrol offers an integrated set of solutions for protecting and securing your buildings, assets, employees and the public. And because Sonitrol products and solutions are listed on a GSA Schedule (GS-07F-9298S), we can work with you to implement electronic security solutions for your facilities at the lowest fixed price.

WAREHOUSE & DISTRIBUTION

Traditional security systems are limited by the size and layout of a warehouse or distribution center. Even with multiple motion sensors to protect each door, aisle or row of goods, vulnerabilities still exist in the ceilings and walls. Using our unique audio & video verification technology, our Audio Sensor can cover up to 5,000 square feet of open space.

OUR HISTORY
A heritage of technical innovation.
1960

Robert Baxter, of Anderson, Indiana, installed microphones within the walls of a building to listen for termites and pinpoint their location. Baxter invented other sound-related devices, too. On June 16, 1960, he incorporated "Sonitrol", from the words sound and control, to manufacture and market his innovations. 

Bob Baxter
1963

In 1963, Baxter met Al Cronk, a local police officer who owned an alarm company. Cronk was frustrated with systems that seemed to let the perpetrators get away. He joined with Baxter, the inventor, to develop ideas for a new alarm company. Baxter responded with the audio sensor, and Sonitrol was born as a security company the following year.
