Blink Video Doorbell (2nd Gen) vs Google Nest Doorbell (battery)

The Google Nest Doorbell (battery) wins overall: it is better rated, adds dual-band Wi-Fi, free short-term storage and on-device people, package, animal and vehicle alerts with no plan. The Blink Video Doorbell (2nd Gen) is cheaper with a much longer battery, but it is HD, Alexa-limited and stores nothing locally.

Subscription-free smart alerts. The Google Nest Doorbell (battery) distinguishes people, packages, animals and vehicles on-device without any plan and keeps free past-3-hours clips, while the Blink Video Doorbell (2nd Gen) offers only basic motion for free and pushes recordings to a paid cloud plan.

The Blink Video Doorbell (2nd Gen), rated around 2 years on 3 AA batteries, against roughly 6 months for the Google Nest Doorbell (battery) whose life varies with traffic and cold. Both can also be wired, though the Blink still needs its batteries when wired.

Only the Google Nest Doorbell (battery), which integrates deeply with Google Home (plus Alexa and Home Assistant) and shows the feed on a Nest Hub. The Blink Video Doorbell (2nd Gen) works with Alexa and IFTTT but not Google Home.

Google households that want accurate people, package, animal and vehicle alerts with no subscription, a tall head-to-toe view, custom ringtones and free short-term clips. It is the smarter, better-connected doorbell of the two.

Budget Alexa or Blink households that want the cheapest doorbell with the longest battery and customizable motion zones, and who do not need on-device smart alerts, Google Home or local storage. It is the low-cost, low-maintenance pick.
