Overview
Blink Battery Doorbell — wire-free video doorbell with motion and two-way talk through the Blink app.
Blink cameras and doorbells deliver motion alerts, Live View, and optional clip recording through the Blink app. Most models require a Sync Module 2 or XR on the same account. Clip storage may use cloud subscription, local hub storage, or both depending on settings.

Before You Service or Replace One
- Exact SKU on label — Outdoor 4 vs 2K+ vs legacy mount patterns differ.
- Sync Module online in app before blaming camera hardware.
- Battery type — lithium AA where specified; extension packs are model-specific.
- Subscription — cloud clip history requires active Blink plan where offered.
- Wi-Fi at mount — not just at router location.
