Welcome to Shooter Detection Systems

SDS was created to assist in reducing the growing threat from indoor shooting incidents. Schools, malls, airports, government and private buildings have all experienced increased shooting incidents over the last few years. In many of these cases, the delay in the time it took to accurately report and locate the shooter has lead to unfortunate consequences.

SDS Guardian Indoor Gunshot Detection system constantly monitors for gunshot fire and instantly sends confirmation that a shot has occurred. With SDS sensors installed in your school, mall, government or private building, this critical, time sensitive information can be immediately relayed to the building’s occupants—as well as emergency personnel outside—so that the proper steps can be taken to mitigate the immediate threat. By removing the “human factor”, nothing is left to interpretation and critical delays can be avoided. Our fully-automated, cost effective indoor gunshot detection system is easily installed into your existing building infrastructure and was designed for compatibility with current security systems, auto-lockdown technologies, closed circuit surveillance cameras and automated alert systems.

Guardian’s core technology was developed in conjunction with the Defense Advanced Research Projects Agency (DARPA) and by a major defense contractor who has deployed over 10,000 military-grade gunshot detection systems to Iraq, Afghanistan and around the globe. These systems have saved many American and NATO Soldier’s lives. This same capability is now available to the commercial market through SDS.
