Blink’s Video Doorbell Add-On is for those already in their ecosystem. It’s a straightforward upgrade that delivers a clear, head-to-toe view of your doorstep without rewiring. The key detail is that it requires a Blink Sync Module 2 to function, which is sold separately.

The 150-degree field of view and 1440p square video format mean you see a person from shoes to hat, not just a torso. Motion alerts are sharp, and the two-year battery life on two AA lithium cells is a legitimate relief from constant maintenance. Setup is simple if you already have the Sync Module.

This is a purpose-built extension, not a standalone starter kit. For existing Blink users, it’s a seamless and reliable addition. For everyone else, the initial cost includes buying the hub.
