About Sonitrol Canada

History of Sonitrol

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.

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.

Today, Sonitrol provides tailored local service in approximately 180 cities throughout the United States and Canada. Sonitrol is the third largest commercial security company in North America—and the leader in verified electronic security. 170,000 apprehensions and counting.

Why Choose Sonitrol?
What Sets Us Apart:

The ability to verify an alarm event in real time gives Sonitrol unrivaled credibility with local law enforcement. This 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.

Tips for managing your security & assets:
  • No matter the size of your business and regardless of the economic climate, it is essential to practice sound business management at all time. The rewards of running a successful business are great, but the risks are many.
  • Security is a real concern for many business owners today – keeping track of inventories and providing a safe workplace for employees is essential for successful business operations and profits. The first measure is to identify the assets and areas are at risk and determine how to guard against potential loss. A thief can steal more than just money in a cash register. For instance, intruders may be searching for valuable trade secrets or expensive office equipment (i.e. laptops, database or other costly assets.
  • In addition, Sonitrol’s access control has many capabilities other than simply controlling entries and exits. We can work with you to design a smart system so you can give access permissions to authorized individuals for certain secured areas, give timed access to cleaning staff or other authorized contractors, and provide activity reports of your facilities as needed.
