Roll Call
Every student. Every staff member. Accounted for in 60 seconds.
Trellis Roll Call is a mesh-powered accountability system that works when traditional infrastructure fails. No WiFi needed. No cell towers required. Just devices talking to devices.

Watch a simulated roll call unfold in real time. This is what administrators see during an incident.
How It Works
From incident detection to full accountability in four seamless steps.
Incident Detected
Automatic trigger from fire alarm, lockdown, or manual initiation by authorized staff.
Mesh Ping Sent
Every Trellis device in range receives an accountability ping via BLE and WiFi mesh networking.
Responses Collected
Staff tap “Safe” or “Need Help” — students auto-respond via proximity detection.
Dashboard Updated
Real-time results stream to the web command center and directly to first responder feeds.
