FAQ

How does remote monitoring work?

When you start monitoring, a unique room link is created. Share this link with your phone or another device — it shows real-time sound levels, event history, and allows live audio streaming.

Are audio recordings stored on the server?

Yes, 30-second audio clips are uploaded when loud sounds are detected (if recording is enabled). They are automatically deleted after 24 hours. Maximum 50 recordings per room.

Does it work with the screen off?

The monitor needs the browser tab to be active. On mobile, keep the screen on and the tab in the foreground for continuous monitoring.

How does live audio streaming work?

The viewer can listen to the monitor in real-time via WebRTC — audio goes directly between devices (peer-to-peer), not through our servers.
