SENSA. Safety you can wear.

Instant support for your loved ones when every second counts.

Say “Hey SENSA.”
Help is on the way.

No phone. No apps. No screen. Just immediate, reliable support.

Designed for life’s unpredictable moments.

Where phones aren’t allowed, SENSA is.

For your child

Where phones aren’t allowed, SENSA is.

Cornered behind the gym, phone locked away by school rules — your child just says “Hey SENSA,” like calling out to you. You’re alerted, the school is called, and the school steps in.

For the ones who always answered.

For your parents

For the ones who always answered.

Independence for an aging parent, reassurance for you. One word or one press reaches family instantly — with a device that never looks medical.

One press · family notified · nothing to learn

Run light. Never alone.

For yourself

Run light. Never alone.

An evening jog, no phone, someone following too closely. She says “Hey SENSA” without breaking stride — her precise location and live audio stream straight to her partner.

Live location · live audio · hands stay free

One word. Three things happen.

01

Say “Hey SENSA.”

It listens locally for one phrase only — or press the SOS button.

02

It understands.

Dual microphones capture what’s happening; AI reads the context — voice cues, location, the kind of emergency.

03

Your people are called.

SENSA itself places real calls over its built-in cellular — no phone needed — sharing name, trigger, location, time, and a callback number.

Triggered by mistake? Cancel within a short window before anyone is notified.

The next 60 seconds.

An illustrative example of a configured response.

Wake word detected · location pinned · workflow started

Someone’s following me. I just got off the train.
Contacting your emergency contacts and sharing your live location now.

3 contacts notified · call placed

I’m inside. I’m okay.
Glad you’re safe. An encrypted record of this event has been saved for your review.

Illustrative example, not a recording of an actual event.

Not just an alarm. An understanding.

A standard SOS button sends a notification that leaves you wondering. SENSA sends context: what was said, where it happened, and what kind of emergency it is.

Everything SENSA does.

Listening, not recording

SENSA listens locally for “Hey SENSA.” In standby it never records or uploads audio.

Only after you trigger

Audio and location processing begin only after the wake word or the SOS button — and everything is transmitted securely.

Yours, then gone

Incident records are encrypted, visible only to authorized contacts, and deleted after the retention period.

Up to 3 trusted people you choose during setup.

Is there a subscription fee?+

Your purchase includes 12 months of Aegis Plus. After that it’s $4.99/month, and an active subscription is required for operation.
