With Sonitrol's impact-activated audio detection, there's no guessing whether or not you have an emergency. We verify every alarm, so help responds to your emergency quicker. Say goodbye to false alarms. With audio sensors and video equipment that cover every inch of your facility, we can easily verify whether an alarm is a mistake or an intruder.

So the police arrive to your facility quicker. No more second guessing what happens when you're away. We install and monitor the latest cameras and digital video recorders in your facility to give you proof of what's happening onsite-even if you're offsite.

In the early 1960s, Robert Baxter of Anderson, Indiana invented sound-based technology to detect termites in walls. Baxter and Cronk modified the equipment to work as a security system and, in 1964, Sonitrol (from combining "sound" and "control") became a reality. Today, Sonitrol provides local service to cities across the US, and to several in Canada and the UK.
When an alarm is detected, we use audio sensors to give officers real-time information about the suspect, helping them respond to the scene quickly, safely and strategically. And when a police officer apprehends a suspect because of one of our alarms, we give them a Certificate of Excellence and a branded duty bag.
Say goodbye to break-in blind spots. We custom design and install security systems that cover every inch of your facility, then monitor and verify the alarm activity. So we'll detect a break-in at your facility, and dispatch the police as soon at it happens. Using impact activated audio detection sensors, we listen-in when an armed sensor detects sound to determine if it is an intruder or a false alarm. We listen to live audio from your sensors to give the police real-time information about the intruder.
Worried about who goes where in your facility? We install and monitor electronic ID cards and door readers that let you control which areas employees and visitors can access. Plus, changing access is easy, so you'll never have to pay hefty costs to re-key your facility. With Managed Access, our core service, we can monitor your access controls 24/7 from our central monitoring station. We can record cardholders, correlate video and access events, and generate entry and exits reports, so you know exactly who's going where.

Sonitrol ROCKS! Security in your home or business doesn't get any better than Sonitrol of Lexington. From sales, to service, to installation, and monitoring; the people that makeup Sonitrol are top notch across the board. I have had the privilege of knowing how good Sonitrol was for many years now (20+ years) but last night proved it once again; a would-be-thief was caught and apprehended by police before they had a chance to walk off with anything. Thank you Sonitrol; your alertness to the slightest sounds inside the house allowed for disaster to be averted. You guys ROCK! Thank you again.

Sonitrol is fantastic. I have been working with them for nine years now. When I have a problem or need a badge or assistance, they are fast, friendly and efficient. I have never, in nine years, had a complaint. Olivia, Tara, Tay and Jade, just to name a few in Customer Service, have all been fantastic. They know the right questions to ask and they know how to answer all of my questions. If they don't they find someone who does. And they do it fast! If you want a company that puts you first, Sonitrol is the one for you. They ROCK!
