Aqara Smart Video Doorbell G4 vs Blink Video Doorbell (2nd Gen)

The Aqara Smart Video Doorbell G4 is better overall, with free local microSD storage, Apple HomeKit and broad platform support. The Blink Video Doorbell (2nd Gen) is much cheaper and lasts far longer on battery, but it is Alexa-only and its new Sync Module removes local storage.

Ecosystem breadth and storage. The G4 works with HomeKit, Google, Alexa and Home Assistant and stores video locally for free, while the Blink Video Doorbell (2nd Gen) works only with Alexa and IFTTT and effectively pushes you to a paid cloud plan since its Sync Module has no local storage.

The Blink. The Blink Video Doorbell (2nd Gen) is rated around 2 years on 3 AA batteries, well beyond the Aqara G4's 4-month rating on its AA pack. If maximum time between battery changes is the priority, Blink clearly leads.

Only the Aqara. The Aqara Smart Video Doorbell G4 records to microSD with no fee (plus 7 days of free cloud), while the new Blink Video Doorbell (2nd Gen) Sync Module has no local storage, so saving video effectively requires a paid cloud plan.

Apple households that want a subscription-free HomeKit Secure Video doorbell with free local recording and extras like custom ringtones, voice changing and automatic replies, and who want broad platform support.

Budget buyers in an Alexa or Blink household who value the very long AA battery life and low price, and who do not mind paying for a cloud plan and skipping HomeKit, Google and local storage.
