Active Shooter Location Identification helps:

In the instance of an active shooter on your site, time is of the essence. While traditional “gunshot detection” methods can take minutes to identify threats, our ASLI system identifies the threat in real time. This increases the amount of time intended victims have to get to safety as well as improving law enforcement’s tactical response time and situational awareness.

Automated Protection

When a threat is detected, ALSI immediately communicates with access control systems, intelligently locking doors and gates to create a physical barrier between the intruder and intended victims, while initiating active shooter protocol, alerting site operators, and auto-dialing 911, to send situational details to responding law enforcement.

Sophisticated AI Advantage

Our advanced AI-enabled systems provide law enforcement critically important contextual video details, highlighting the intruder’s location. Optional modules include facial and license plate recognition, providing law enforcement the information needed to quickly identify the suspect.

Real-Time Video/Audio

Our ASLI solution utilizes real-time video and audio to pinpoint the location of active shooters on your grounds. Battlefield-tested hardware and HD Pan-Tilt-Zoom cameras instantly capture audio and video of an active shooter or threat while withstanding environmental wear and tear.

ASLI Advantage: When Seconds Count

Our AI-powered Active Shooter Location Identification (ASLI) systems take site security to the next level, reducing false alarms and eliminating the shortcomings of previous security systems. 

Immediate Response Time

​When responding to active shooter situations, information on the shooter and the situation is key. Twenty20 Solutions' Active Shooter Location Identification (ASLI) technology only takes seconds to detect and respond to shooting threats, capturing audio and video of shooter(s) and sending the data directly to law enforcement.
