Second major award in 2025 highlights SDS’ innovation in outdoor and perimeter security

Shooter Detection Systems (SDS), an Alarm.com (NASDAQ: ALRM) company and a leader in gunshot detection technology, today announced that its new outdoor gunshot detection system has been named the winner of the 2025 SecurityInfoWatch.com Readers’ Choice Awards in the Threat Detection category.

FBI data on active shooter incidents shows that many attacks begin outside targeted facilities – in parking areas, building entrances, or open campus spaces – before moving indoors. These perimeter environments are critical to secure and SDS Outdoor was designed to close this protection gap and deliver instant, precise detection that empowers security systems, security teams and first responders to act before an incident escalates.

SDS Outdoor builds on SDS’ proven indoor gunshot detection technology by extending dual-mode acoustic and infrared flash detection capabilities into outdoor spaces. Each sensor covers up to 15,700 square feet while identifying shooter location and firearm type with an industry-leading 99.9% accuracy rate. Proprietary algorithms and the use of dual-mode sensor technologies distinguish SDS Outdoor as the first of its kind in the market.

“We are deeply honored to receive this prestigious award,” said Kendra Noonan, Director of Communications at SDS. “Winning the SecurityInfoWatch Readers’ Choice Award in Threat Detection reinforces our mission to deliver trusted, actionable intelligence that empowers security teams and first responders to detect gunfire incidents with speed and accuracy when every second counts.”

The SecurityInfoWatch Readers’ Choice Awards recognize the most impactful and trusted products in the security industry, as voted by professionals across physical security, electronic security, and risk management. Winners reflect peer validation and real-world adoption of solutions that deliver measurable results.

More than a detection device, SDS Outdoor is a cornerstone technology for a comprehensive security strategy. The sensor seamlessly integrates with video surveillance, access control, and mass notification systems, allowing immediate visual confirmation, lockdown procedures, and alerting to all necessary stakeholders.

SDS Outdoor is purpose-built for high-risk, open-air and perimeter environments, including:

• Corporate campuses and building entrances
• Hospital emergency room entrances and ambulance bays
• Transportation hubs, parking facilities, and event venues
• Critical infrastructure sites and educational institutions

By detecting and communicating outdoor gunfire events in real time, SDS Outdoor gives organizations the ability to respond swiftly and before a shooter can gain access to a building or other crowded space.
