Why Choose Us

A Heritage of Technical Innovation
The company known today for detecting burglars had its roots in pest control of a different sort in the late 1950s.
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.
Law Enforcement Legacy
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 hired Baxter, the inventor, to develop new ideas for the alarm company. Baxter responded with the audio sensor, and Sonitrol was born as a security company.
Success Spreads
Today, Sonitrol provides tailored local service in approximately 180 cities throughout the United States and Canada. Now the third largest commercial security company in North America, Sonitrol is the clear leader in verified electronic security.

Sonitrol provides businesses with a single source of integrated, state-of-the-art security solutions for intrusion, video, access and fire, all backed with professional monitoring by experienced, trained personnel.
Our technology sets us apart. The ability to verify an alarm event in real time gives Sonitrol unrivaled credibility with local law enforcement. That is a key advantage as a growing number of municipalities pass Verified Response regulations requiring verification that an intrusion is actually taking place before police will dispatch personnel to the site.
Sonitrol has the best apprehension rate in the industry – and the fewest dispatches for false alarms. In fact, in January 2006, Lehman Brothers named Sonitrol “the leading alarm verification company.” And our integrated components allow us to customize a solution that can expand easily as your needs grow.

Why? Because Sonitrol alarms are reliable. The false alarm rate of conventional systems can reach 98 percent. Sonitrol’s ability to immediately verify an alarm keeps our false alarm rate low. Sonitrol is able to detect a break-in while an intruder is still attempting to gain entry – no matter where the entry point is. Sonitrol signals are monitored 24 hours a day, 7 days a week by highly trained professionals. As soon as an alarm signal is received, an operator begins to listen to live audio from your building. No other system can give police such accurate, up-to-the minute information as they respond to the scene. The result? Sonitrol has a high apprehension rate, low false alarm rate, and increased safety for police officers.
Conventional Security Systems:

• Partial coverage, from limited points of entry.
• Activate after break-in, with intruder inside.
• Most call facility to verify break-in, then call you to see if they should send police.
• Most use audible alarms which alert intruders and make it easy to test the system.
• Cannot tell the difference between real trouble and false alarm.
• False alarm rate of up to 98%.

The Sonitrol Difference:

• Complete coverage from any point of entry.
• Detection while intruder is still attempting to gain entry.
• Sonitrol operators confirm with live audio immediately, call police and stay in contact to help with apprehension.
• Silent alarm leads to Sonitrol’s high apprehension rate.
• Highly trained operators listen to live audio, recognize non-threatening noises and reset system.
• Sonitrol has a lower number of false alarms, and a false alarm guarantee.

Sonitrol provides the modular, scalable alarm systems Delaware trusts.
Crime is rising. More than 700,000 commercial buildings were burglarized in 2005 and employee theft is estimated to exceed $10 billion a year. Fire and explosions cost businesses another $2.3 billion annually, and they kill or injure thousands of workers. Workplace violence, lawsuits and false insurance claims can also put a significant strain on your business and security resources.

Traditional security systems aren’t up to the job. One out of four forced entries today are through unconventional entry points, so they circumvent conventional perimeter protection. What’s more, more than 90 percent of alarms are false. False alarms take valuable law enforcement, fire and EMS personnel away from real emergencies and make your alarm system less credible—reducing response time. Many jurisdictions now levy fines for excessive false alarms—and a growing number won’t respond without some form of alarm verification.
