  • Alarm.com (Nasdaq: ALRM) recently announced it has acquired Shooter Detection Systems, LLC (SDS). These are the details.

Alarm.com (Nasdaq: ALRM) recently announced it has acquired Shooter Detection Systems, LLC (SDS), the leading provider of indoor gunshot detection technology. SDS launched in 2013 to address the growing active shooter threat to the public by advancing proven military gunshot detection technology. 

SDS has developed the Guardian Indoor Active Shooter Detection System, which is a unique combination of acoustic and infrared sensors and proprietary algorithms that accurately detects gunshots and communicates shooting incident details rapidly to building occupants and security teams. And the acquisition of SDS expands the commercial solutions offered by Alarm.com and helps its partners outfit commercial and enterprise customers with the premier gunshot detection solution.

SDS technology is integrated with leading video, access control, mass notification and alarm systems for providing enhanced situational awareness during shooting incidents. And the combination of SDS technology with Alarm.com’s industry-leading suite of interactive cloud-based video, access control, intrusion and automation will deliver new levels of safety and security for commercial enterprises of all sizes.

SDS’s Guardian System is currently being used in locations across the United States, which protects U.S federal and state government buildings, schools, airports and other transportation hubs, and entertainment facilities.

And with the acquisition, SDS will be a subsidiary of Alarm.com and continue to be led by the existing management team. Plus SDS also will continue to support its existing customers and partners. Going forward, Alarm.com and SDS will work together to further advance SDS’s engineering and development of gunshot detection solutions as well as integration with the Alarm.com ecosystem.


“With their patented dual mode technology, SDS is the clear leader for indoor gunshot detection. They address a real security need and are the best engineering team in the space, having pioneered the most proven and accurate approach to the problem. Acquiring SDS allows us to tap into their established resources and give our partners the opportunity to capture the active shooter solutions market.”
