Shooter Detection Systems (SDS), an Alarm.com company, announced the issuance its seventh patent by the U.S. Patent and Trademark Office for its gunshot detection technology. 

The patent — US 11,417,183; titled Cable-Free Gunshot Detection — describes the application of indoor gunshot detection sensors that use a cable-free device powered by a battery. The foundational concepts and designs in this patent are currently offered by SDS as their Guardian Wireless product, a dual mode acoustic and infrared gunshot detection sensor that has been on the market since 2019. 

The patent builds on earlier SDS patents, specifically US 10,657,800 B1 titled Gunshot Detection Within an Indoor Environment, which focused on techniques for privacy-centric gunshot detection in an indoor environment utilizing two-factor authentication. The Guardian Wireless product has allowed SDS to achieve commercial success by meeting its goal of lowering overall customer costs by as much as 40-60 percent via reductions in overall project infrastructure costs.

“SDS works tirelessly to give our customers the most accurate, value-driven solution on the market today,” said Richard Onofrio, SDS’ managing director, member of the sensor design team and co-author of the patent with Ronald Fowler, CTO for SDS. “I am extremely proud of our entire engineering team. A strong patent portfolio demonstrates unequivocally to experts, clients, and investors that SDS is the industry leader in this domain.”

Fowler added, “Not all technical advances are patentable. The innovations that our team has made clearly deserve the attention and recognition that comes when a U.S. patent is awarded.”

This latest patent marks the seventh gunshot detection patent owned by SDS, following its 2020 patent for techniques for indoor gunshot sensor testing.  

Alarm.com acquired SDS in 2020. The company's technology is integrated with video, access control, mass notification and alarm systems to provide situational awareness during shooting incidents.
