Acoem Showcases New AI Model and On-Premises Cadence Software for ATD Gunshot Detection System at GSX 2025

At GSX booth #3307, Acoem, a global leader in advanced physical security solutions, will showcase important updates to its ATD gunshot detection technology, and a new on-premises option for its Cadence software, reinforcing its position as a leader in edge-based acoustic AI gunshot detection.

Unlike legacy systems that depend on multiple sensors or remote servers, the Acoem ATD System conducts detection and classification directly on the edge. With ATD technology, PTZ cameras can immediately slew to the source of gunfire, giving first responders and security teams real-time situational awareness and captured evidence. More cost-effective than infrastructure-heavy multi-sensor systems, the ATD system delivers high accuracy with a single device, simplifying deployment and management across campuses, utilities, and city environments.

The Acoem ATD-300 Sensor, already recognized for its single-sensor detection accuracy and deployment flexibility, is receiving its most advanced neural net update yet. The latest version of the AI model is built on a library of hundreds of thousands of qualified sounds collected over three decades, with up to 15,000 new sounds added monthly from live deployments. Acoem’s engineering team, together with end-users through Cadence, continually validates and classifies noise events to refine detection. This evolving, multi-modal approach is designed to drive false positives toward zero while preserving unmatched accuracy in complex environments. In addition to these regular updates, the ATD AI engine can be custom tuned for each deployment, learning and rejecting nuisance sounds unique to each individual environment.

“A recent example involved a gunshot sensor installed near a baseball field. The Acoem team was able to register the crack of the bat against the baseball with the neural net to ensure a home run is never interpreted as a gunshot, even though the sounds share very similar characteristics," said Timothy English, Managing Director for Acoem ATD technology.

Acoem will also preview an on-premises version of its Cadence software. Until now, the Cadence software has been operated only as a cloud-based platform. For mission-critical environments such as utilities, government, and remote facilities, where outside internet connections are restricted for cybersecurity reasons, the new option will allow the software to run entirely inside an organization’s own network.

The Cadence software provides security teams with a single platform to easily manage ATD deployments. It streamlines ATD-300 sensor setup and alarm notifications and verifies alerts with live audio clips for optional human validation through integrated VMS systems. It also handles all management and updates while monitoring sensor health. Unlike other platforms that centralize control, Cadence gives organizations direct autonomy to monitor sensors, validate alerts, and manage deployments in real time. Users can customize views around high-risk “hot spots,” and even contribute site-specific sound validations that strengthen the AI model over time.

“Security leaders are demanding both greater accuracy and greater deployment flexibility,” says English. “With the new AI model, we’re raising the bar yet again on false positive rejection, and with on-premises Cadence software, we’re removing barriers for critical infrastructure sites that require closed-loop operations.”

GSX attendees are invited to experience live demonstrations of the ATD system and Cadence software at booth #3307.

  • The Evolution of IP Camera Intelligence

    As the 30th anniversary of the IP camera approaches in 2026, it is worth reflecting on how far we have come. The first network camera, launched in 1996, delivered one frame every 17 seconds—not impressive by today’s standards, but groundbreaking at the time. It did something that no analog system could: transmit video over a standard IP network. Read Now

  • From Surveillance to Intelligence

    Years ago, it would have been significantly more expensive to run an analytic like that — requiring a custom-built solution with burdensome infrastructure demands — but modern edge devices have made it accessible to everyone. It also saves time, which is a critical factor if a missing child is involved. Video compression technology has played a critical role as well. Over the years, significant advancements have been made in video coding standards — including H.263, MPEG formats, and H.264—alongside compression optimization technologies developed by IP video manufacturers to improve efficiency without sacrificing quality. The open-source AV1 codec developed by the Alliance for Open Media—a consortium including Google, Netflix, Microsoft, Amazon and others — is already the preferred decoder for cloud-based applications, and is quickly becoming the standard for video compression of all types.

  • HD2055 Modular Barricade

    Delta Scientific’s electric HD2055 modular shallow foundation barricade is tested to ASTM M50/P1 with negative penetration from the vehicle upon impact. With a shallow foundation of only 24 inches, the HD2055 can be installed without worrying about buried power lines and other below grade obstructions. The modular make-up of the barrier also allows you to cover wider roadways by adding additional modules to the system. The HD2055 boasts an Emergency Fast Operation of 1.5 seconds giving the guard ample time to deploy under a high threat situation.

  • ResponderLink

    ResponderLink

    Shooter Detection Systems (SDS), an Alarm.com company and a global leader in gunshot detection solutions, has introduced ResponderLink, a groundbreaking new 911 notification service for gunshot events. ResponderLink completes the circle from detection to 911 notification to first responder awareness, giving law enforcement enhanced situational intelligence they urgently need to save lives. Integrating SDS’s proven gunshot detection system with Noonlight’s SendPolice platform, ResponderLink is the first solution to automatically deliver real-time gunshot detection data to 911 call centers and first responders. When shots are detected, the 911 dispatching center, also known as the Public Safety Answering Point or PSAP, is contacted based on the gunfire location, enabling faster initiation of life-saving emergency protocols.
