Blink Video Doorbell (2nd Gen) vs Google Nest Doorbell (wired, 3rd Gen)

The Google Nest Doorbell (wired, 3rd Gen) is the better pick overall. It records 2K HDR video, connects over dual-band Wi-Fi, and runs on-device people, package, animal and vehicle detection, plus custom indoor and outdoor ringtones. The Blink Video Doorbell (2nd Gen) costs less and lasts about 2 years on AA batteries, but it is 2.4GHz-only and works only with Alexa and IFTTT.

Smart-home reach and video. The Nest works with Google Home, Alexa and Home Assistant, shoots 2K HDR, and identifies packages, animals and vehicles on device. The Blink Video Doorbell (2nd Gen) is limited to Alexa and IFTTT with HD video and no 5GHz Wi-Fi, so it fits a narrower setup.

The Blink Video Doorbell (2nd Gen) is the more affordable of the two, and its 3 AA cells are rated to run for roughly 2 years. If keeping the upfront cost down and rarely swapping power matters more than 2K video or a wide platform list, Blink is the value pick.

The Nest gives you free event clips from the past 6 hours plus a 1-hour offline buffer, but longer 24/7 history needs Nest Aware. The new Blink Sync Module has no local storage, so saving video effectively requires a paid cloud plan. Neither offers unlimited fee-free recording.

Google and Nest households that want sharp 2K HDR video, accurate on-device smart alerts, custom ringtones and one app for the whole home. It rewards buyers with existing doorbell wiring and a Nest Hub or speaker for the indoor ring.

Budget-focused Alexa or Blink owners who want a low price and very long AA battery life, and who are comfortable being 2.4GHz-only, paying for a cloud plan for saved video, and skipping Google, HomeKit and Matter.
