Blink Video Doorbell (2nd Gen) Review
Our verdict
At under $70 — and often half that on sale — the Blink doorbell is the budget king. Three AA lithium batteries can last up to two years, and the Sync Module Core adds local storage. You give up some video polish and smart detection versus pricier rivals.
Pros and cons
What we like
- Up to 2-year battery life on 3 AA lithiums
- Local storage via Sync Module Core
- Very low sale prices
What could be better
- 1440p video trails 2K rivals
- Person detection needs subscription
