Indoor gunshot & glass-break detectionSeconds matter. Know where to go.
OMNI Sentinel Plus listens for gunshots, breaking glass, screams, aggression and spoken calls for help, analyzes the sound on the device, and alerts responders with the exact room. It never records conversations.
Acoustic detection without recording.
Analyzes sound on the device
The acoustic sensor recognizes the signature of a gunshot, breaking glass, a scream or aggression. Audio is processed inside the unit and never recorded or stored.
Alerts with a location
Responders get an alert by text, email and the dashboard that names the device and room, so they know where to go instead of searching.
Triggers your other systems
Through integrations, an alert can pull up nearby cameras in your VMS, start an access-control lockdown or send a mass notification.
Active-threat awareness in every room.
Gunshot detection
Indoor acoustic gunshot detection for hallways, lobbies, offices and gathering spaces.
Glass-break detection
Know when a window or door glass breaks, day or night.
Aggression & keyword alerts
Scream and aggression detection, plus spoken keyword alerts so someone can call for help without a device.
Panic buttons included
Wearable panic buttons with live location come with Sentinel Plus for staff who need a silent way to call for help.
OMNI adds awareness and speed to your emergency plan. It does not replace calling 911 or your existing life-safety systems.

Gunshot detection questions
How does indoor gunshot detection work?
The acoustic sensor in Sentinel Plus recognizes the sound signature of a gunshot and sends an alert naming the device and room. The same sensor detects breaking glass, screams and aggression.
Does it record conversations?
No. Sound is analyzed on the device and never recorded or stored, so Sentinel Plus can go in spaces where cameras and microphones aren’t appropriate.
Can it work with our cameras and access control?
Yes. Sentinel Plus integrates with VMS/PSIM platforms, access control, mass notification and other systems through integrations, an open REST API and webhooks.
Is it a separate device from the vape detector?
No. Sentinel Plus does everything the standard Sentinel does, including vape, smoke and air quality monitoring, and adds gunshot, glass-break and aggression detection, panic buttons and asset tracking.
Does it replace calling 911?
No. OMNI speeds up awareness and response inside your building. It complements your emergency plan, 911 and existing life-safety systems.
