Amazon's new Blink doorbell requires extra Sync Module for functionality

In late May 2025, Amazon launched an updated version of the Blink video doorbell, featuring several new enhancements aimed at improving user experience. These improvements include a 'head-to-toe' HD live view and an expanded field of view of 150 degrees, alongside a resolution upgrade from 1080p to 1440p. The device also boasts better weather resistance with an IP65 rating, enhancing its usability in various environmental conditions. One of the most notable upgrades is the promised two-year battery life using standard AA batteries, a claim that has been substantiated by usage tests on previous Blink models. However, while the battery longevity seems reliable, the new doorbell introduces a significant limitation: the requirement for a Sync Module, which is not included in the purchase. This mandatory component serves as a connection hub, and has raised concerns among prospective buyers considering the additional costs associated with local storage. The Sync Module, priced at $10, allows users limited functionality, primarily cloud storage for video feeds, which costs $3 per month for a basic subscription that includes storage for up to 60 days. For users seeking to store video locally, they would need to acquire the Sync Module 2 for $50 or the Sync Module XR for $70, either of which would necessitate the purchase of external storage devices. These unexpected costs could deter potential buyers, especially those who were drawn in by the doorbell's original price point. While the new features significantly enhance the technical capabilities of the doorbell, the financial implications of needing additional components for basic functionality may lead to mixed reactions from consumers. Evaluating these costs versus benefits will be crucial for buyers determining whether to invest in the updated Blink doorbell, especially in a competitive market for smart home devices.
