See who set it off.
A wireless outdoor motion detector with two PIR sensors and a built-in camera, so an alarm comes with a photo you can check instead of just a notification.

Detection you can verify
Built to watch outdoor areas, cut down on false alarms and keep running on its own battery.
Photo verification
A built-in camera supports photo verification, with photo on demand and photo by alarm.

Detection distance
The detector covers up to 15 m.
Fewer false alarms
A false alarms prevention algorithm, pet immunity, anti-masking and temperature compensation work together to keep detection reliable.
Long battery life
Runs up to 3 years on the pre-installed battery.
Simple setup and control
Connect by QR code, install or replace it with little effort, and control and configure it remotely in the app.
