How a Shooter Detection System Can Save Lives and Strengthen Business Security

A gunshot detection system recognizes gunfire the instant it happens and automatically alerts your monitoring center, your staff, and responders, so help is requested in seconds instead of minutes. Sting Alarm installs Shooter Detection Systems sensors powered by Alarm.com, which combine acoustic and infrared detection, as part of complete business security for schools, offices, warehouses, retail, and other facilities in Las Vegas and Phoenix.

When violence breaks out, it happens fast, with no warning and no time to think. People hide, run, and try to make sense of what they heard. Calls to 911 can be delayed or confused. A shooter detection system removes the guesswork: the building itself reports what happened, where, and when.

How a gunshot detection system works

Two sensors, one confirmation

Each indoor sensor listens with microphones for the acoustic signature of a gunshot and watches with infrared sensors for the muzzle flash. According to Alarm.com's product documentation (checked 2026), the dual-sensor approach detects gunshots with a greater than 99% accuracy rate.

Detection in under a second

When a shot is detected, the signal goes to Alarm.com's cloud platform, with detection in less than one second according to Alarm.com, and the central station is alerted within seconds.

Coverage without line of sight

Each sensor's field of view covers 2,500 square feet, and direct line of sight to the shooter is not required, according to Alarm.com. Sensors can be flush mounted on walls or ceilings, or surface mounted on brick, concrete, and other hard surfaces.

What happens after a shot is detected

1. The monitoring center is alerted so operators can act on the event immediately.
2. Notifications go out to the people you choose, by text and push alert, so staff can start your safety plan.
3. Local alarms and automation can activate through the Alarm.com system, such as sirens or other programmed actions.
4. Responders get better information, including details from the detection, so they know where to go.

Why seconds matter

Every second after a gunshot counts. Faster detection means help is requested sooner, staff can lock down or evacuate sooner, and responders arrive with better information. Automated detection also reduces human error at the moment people are most likely to panic.

Part of a complete business security system

Gunshot detection is strongest when it is connected to the rest of your security:

• Video surveillance so you and responders can see what is happening
• Access control to lock down doors from the app
• Commercial intrusion detection and 24/7 monitoring from our UL-listed monitoring center
• One app across your devices, systems, and team
