This Blink Video Doorbell system lets you see a head‑to‑toe HD view of your doorway with infrared night vision, so you can clearly check visitors and packages from the Blink app at any time. It offers flexible installation (battery or existing doorbell wiring), two‑way audio, motion‑activated alerts, Alexa compatibility, and comes with the Sync Module Core plus all the mounting hardware you need in the box. Many reviewers praise its clear video, wide field of view, easy setup, and convenient app and two‑way audio, while others report issues with Wi‑Fi connectivity, notification reliability, and inconsistent battery life, so it works very well for many homes but may require some troubleshooting in certain setups.

A Blink Sync Module (Sync Module Core included) is required for use. Sync Module Core does not include back-up local storage. You can back up locally with a Sync Module XR and a MicroSD card (up to 256 GB – each sold separately). Blink Video Doorbell is compatible with all Blink Sync Modules.
