New outdoor gunshot detection sensor developed using machine-learning techniques and combining acoustic and infrared sensing for advanced accuracy and earlier threat awareness
Shooter Detection Systems, an Alarm.com company, has introduced SDS Perimeter, extending its proven detection capabilities beyond indoor environments to outdoor spaces.
The new system, now commercially available after successful beta testing, will be showcased at ISC West 2026 at booth #14039.
Expanding Gunshot Detection To Outdoor Environments
SDS Perimeter is purpose-built for exterior environments such as:
- Campuses
- Building perimeters
- Parking lots
- Open-air public spaces
With a significant portion of active shooter incidents occurring outdoors, the system addresses a critical gap in modern security strategies by providing earlier threat awareness before incidents escalate indoors.
Advanced Multi-Factor Detection For Greater Accuracy
The system combines machine learning with SDS’s patented multi-factor sensing approach to deliver highly accurate detection.
Key technologies include:
- Acoustic sensing to identify gunshot sound signatures
- Infrared detection to confirm muzzle flash
- Machine-learning models to reduce false alarms
By verifying events through multiple inputs, SDS Perimeter delivers high-confidence alerts within seconds—even in complex outdoor environments.
Faster Response Through Real-Time Intelligence
SDS Perimeter is designed to provide actionable intelligence, not just alerts.
“Organizations today are looking for security solutions that provide earlier awareness and actionable intelligence, not just alerts,” said Rich Onofrio, Chief Technology Officer at Shooter Detection Systems.
“SDS Perimeter reflects how we’ve continued to evolve our technology—combining physics-based sensing, machine-learning detection models, and real-world validation—to help security teams identify and respond to gunfire events before a threat reaches a populated area.”
With many active shooter incidents unfolding within minutes, early detection enables:
- Faster emergency response
- Improved situational awareness
- Better coordination across security teams
Built On Proven Technology And Research
SDS Perimeter originated from a U.S. Department of Homeland Security-sponsored development initiative, validating outdoor detection concepts before commercialization.
The solution builds on SDS’s legacy in military-grade sniper detection systems, combining:
- Advanced sensor hardware
- Proprietary detection algorithms
- Integration with broader security ecosystems
Importantly, SDS sensors are not surveillance devices and do not record conversations, helping organizations deploy the system without privacy concerns.
Enabling Layered Security Strategies
With the addition of outdoor detection, SDS now supports a fully layered approach to gunshot detection across entire properties.
The system integrates with:
- Video management systems
- Access control platforms
- Mass notification systems
- Real-time crime centers
This enables coordinated, end-to-end response across indoor and outdoor environments.
Shooter Detection Systems delivers real-time threat intelligence during active shooter incidents, helping organizations and first responders detect, locate, and respond to gunfire quickly to reduce harm and improve outcomes.
