Trusted by teams at
A complete paging system in three steps
No amplifiers, no proprietary wiring. Everything runs over the network you already have.
Connect over PoE
Each speaker plugs into a single network cable for both power and audio. Run one wire, mount, done.
Set up your zones
Group speakers into zones and manage everything from the free configuration app or web interface.
Page, schedule & alert
Make live announcements, automate break and shift tones, and trigger emergency alerts instantly.
Keep the phone system you already have
Page directly from your VoIP platform. SIP speakers register as extensions, or bridge IP speakers with a gateway.
Upgrading from an old analog or 70V system? We bridge it, so you keep your existing speakers.
One system, sized to where you work
From a single noisy floor to a multi-building campus, the right speakers for every space.
Warehouse & Manufacturing
Loud horn speakers cut through 85+ dB of machine noise across high-ceiling floors.
Schools & Campuses
Ceiling speakers for classrooms and halls, with automated bell schedules and lockdown alerts.
Offices & Healthcare
Discreet ceiling speakers and clear announcements for offices, clinics, and care facilities, with emergency alerting.
Multi-building & Government
Indoor and outdoor coverage across separate buildings and secure sites, all on one network.
