View details Smart Doorbells — FAQ
Do I need a subscription for video storage?
No. Every model supports a microSD card for local event recording. Cloud backup is optional, not required.
Will the PoE doorbell work with my NVR?
Yes. The PoE model is ONVIF-compliant and streams to any ONVIF recorder just like an IP camera, while also triggering door release through its relay.
How long does the battery last on the Wi-Fi model?
Typical use delivers 4–6 months per charge thanks to PIR wake-up and efficient AI pre-filtering. Actual life depends on event frequency and temperature.
