One button. 24/7 response. No smartphone needed.
The Numera Libris Aura is a wearable emergency pendant stocked and supported by STU — a licensed low-voltage security company. Press the button, reach a live dispatcher.


Hardwired reliability. Wearable form.
The Libris Aura works on cellular and GPS — no landline or Wi-Fi necessary. It goes where you or your loved one goes and connects directly to a 24/7 dispatch center.
Worn as a pendant or belt clip, this pendent is waterproof with two-way voice built in.

Three steps. That's it.
How the Libris Aura works
Press the button
Dispatcher picks up
Help is routed
A live operator answers within seconds — not a recording, not a callback queue. Two-way voice happens directly through the pendant.
GPS location is shared instantly. The dispatcher contacts emergency services or a designated family member — whichever the situation calls for.
A single press sends an immediate alert. No menu, no passcode, no delay. The device works even if the wearer can't speak.
