How does the Smoke Alarm and CO alarm work?

The Wyze Cam’s sound detection algorithm is programmed to detect the pattern of standard smoke and carbon monoxide alarm signals.

For smoke alarms, the Wyze Cam listens for the Temporal-Three (T3) alarm signal, which produces 3 long beeps followed by a pause.

For carbon monoxide alarms, the Wyze Cam listens for the T4 alarm signal, which produces 4 long beeps followed by a pause.

Smoke and carbon monoxide alarms manufactured starting in 1996 have followed this standard set by the American National Standards Institute and National Fire Protection Association. The majority of alarms installed prior to 1996 produced a steady continuous sound.

The Smart Sound Recognition setting on the Wyze Cam is used to generate notifications and event videos. Learn more about Event recording and Smart Sound Recognition by clicking here.
