Install the companion Sonoff app on your smartphone, follow the in‑app setup to connect the camera to a 2.4 GHz Wi‑Fi network, then configure motion detection, active zones and privacy masking as needed. Insert a TF card for local recording or activate the cloud service trial to enable cloud storage. Use the app or a compatible voice assistant to view live feed and communicate via two‑way audio.

Recommendations

For reliable motion detection and minimised false alerts, position the camera away from direct light sources and heating vents, and configure active motion zones to exclude busy background areas. Regularly update firmware via the app and use a quality 5V⎓1A USB‑C adapter. For long-term archival, combine local TF card storage with cloud backup.
