Evolv Visual Gun Detection™

Evolv Visual Gun Detection™ (VGD) identifies individuals brandishing guns at distances up to 100 feet, depending on gun type and orientation, by analyzing 4K high-resolution video streams and leveraging AI.

Combining Selected Cameras and AI

Once a potential threat is detected, a comprehensive image, highlighting the detected gun, along with live annotated video footage from the relevant camera, is transmitted to the onsite security staff, or First Reactor, positioned near the Express system. 

This early warning is designed to help empower security teams to swiftly implement emergency operational procedures, like locking the doors, alerting the broader security team, and getting people to safety.


Use of Cameras

Evolv Visual Gun Detection leverages cameras selected by Evolv with 4K resolution that can reliably detect threats at further distances.

AI Detection

Evolv Visual Gun Detection incorporates Omnilert’s best-in-class video AI detection software to analyze video from Evolv selected cameras in real time and send it to the First Reactor Tablet.

First Reactor

Evolv VGD enables the First Reactor, the security professional stationed at or near an Evolv Express, to receive prompt alerts (threat image + live annotated video), allowing for a rapid security response in seconds.


A: The presence of an Express system and trained staff (“First Reactors”) to manage alerts enhances the value of your layered security approach. That said, even in the absence of Evolv Express, customers can still leverage Evolv VGD by utilizing available resources to swiftly review and respond to alerts.

A: 4K resolution (3840 x 2160). Lower resolution streams will likely reduce detection distance for brandished guns.

A: Expected gun detection distance is generally between 70 – 100 feet, but can vary depending on gun type, lighting, and gun orientation.

A: Evolv VGD alerts are sent directly to the Evolv VGD tablet located near the entrance to enable the First Reactors to review and respond to alerts. Additionally, the command center, broader security team, and first responders receive the same image with a recorded video clip showing when the gun appeared.

A: Evolv VGD alerts are sent swiftly to the tablet and the Mobile and Desktop apps upon the detection of a probable brandished gun.
