All processing happens locally. Nothing leaves your home unless you choose.

Always on

Works offline. Works at night. Works when you're not there.

Autonomous

Doesn't wait for instructions. Perceives, decides, and acts on its own.

How it works

An intelligent agent, not a camera

01

Perceive

Night vision camera and microphone with person detection on a dedicated 40 TOPS NPU.

02

Understand

On-device speech recognition. Claude analyzes intent, tone, and context in real time.

03

Respond

Natural multi-turn conversation. Greets visitors, takes messages, deters threats.

04

Act

Sends notifications. Logs interactions. Escalates threats. Records video. All automatic.

What it protects

Your home, your time, your peace of mind

Your home

Guards every entry point. Greets visitors, deters strangers, logs everything. Five operating modes configurable per device and time of day.

Your time

Handles solicitors, unexpected visitors, and routine deliveries. Takes messages, gives directions, answers questions on your behalf.

Your attention

Instant notifications with snapshots. Face recognition learns your regulars. Full interaction history searchable from anywhere.
