How it works
Alerts that don’t need the internet.
When a lockdown hits, the network is the first thing that fails. Kasmer Signal doesn’t depend on it — it turns every staff phone into a relay that passes the alert device to device over Bluetooth until everyone has it.
Sound the alert.
An admin triggers a lockdown, shelter, evacuate, or custom alert from their phone in one tap.
It spreads device to device.
The alert hops phone to phone over a Bluetooth mesh — iPhone and Android — reaching staff with Wi-Fi and cell down, even on locked phones in a pocket.
Everyone’s accounted for.
Staff tap “I’m safe,” “I need help,” or “I can assist.” Admins watch a live count of who’s safe and who needs help as the responses come in.
Built for the worst day
Everything a lockdown needs — none of what it can’t rely on.
Works when the grid is down
Bluetooth mesh relays alerts with no Wi-Fi, no cell, no towers.
iPhone + Android
One network across every staff device, whatever they carry.
Live accountability
A real-time “safe / needs help / no reply” tally, campus by campus.
Role-aware screens
Staff and students get large, one-tap response buttons; admins get command and the accountability view.
Automatic incident reports
Every alert, response, and update, timestamped into an after-action record you can export for compliance and review.
Runs on the phones you have
No hardware to buy or maintain; staff install on their own devices.
Signed, campus-isolated alerts
Cryptographically signed and scoped to a campus — no spoofing, no cross-campus leakage.
Parents & community by SMS
The wider community gets emergency texts; only staff and admins run the app.
For schools & districts
Deployed to your staff in minutes — no app store required.
Kasmer Signal is provisioned by invitation. You create your organization, your safety coordinator invites staff from the dashboard, and they install in under a minute — TestFlight on iPhone, your MDM or a direct link on Android. Parents and the community get emergency alerts by SMS and install nothing.
Invite-based provisioning
You control exactly who is on the network.
Pilot-ready now
Run a one- or two-campus pilot without waiting on public app-store review.
Grant-eligible
Aligns with BJA STOP, COPS SVPP, and Title IV-A school-safety funding; your district applies, Kasmer Signal is the funded technology.
