The company’s customer service is exceptional. Whenever I have a question, it is answered promptly and courteously. The system is comprehensive, and our entire staff feels secure. I highly recommend Sonitrol.

Baratz & Associates

I am an office manager at a local organization and we have had the pleasure of using Sonitrol for our security system for the past 11 years. Sonitrol provides an effective security system at a reasonable price. Their reps, from sales, installers and customer service, are reliable and responsive to our needs. Sonitrol has helped us with two office relocations, providing expertise in the design of our systems and providing installations in short periods of time. Their online system and mobile app provides easy administration for adding/deleting users, and for monitoring. I highly recommend Sonitrol.

Since 1964, Sonitrol Security has been the trusted name for providing home and business security systems in North America, with a combination of human know-how and the latest technology. Our system is so sophisticated that we often catch criminals before they gain entry to our customers’ facilities.

The cornerstone of our success is our unique impact-activated, audio-based intrusion detection system. Our technology allows us to verify the threat posed by an alarm event before we call the police. That way, we minimize false alarms, create a faster police response, and actually apprehend the criminal! No other business security systems can compete with our solution.
