Reviewed recording configurations
1 exact US configuration, checked against official documentation (latest review: 2026-09-29). These are documentation reviews, not hardware tests. The Planner uses these same facts to show storage allowances, 3/5-year costs and what remains without a paid recording plan.
A local-storage label does not establish continuous recording, smart alerts, offline operation or cloud retention. “Not verified” means this review has not established that feature. Prices keep their own recorded offer dates.

What the 3-year figure includes
Hardware at the lowest recorded US list price plus 36 months of the cheapest plan that saves video for one device. Storage cards, hubs, mounts, tax and shipping are not included; the model pages list which of those each doorbell needs. The eufy Video Doorbell E340 is the cheaper way to own one doorbell for 3 years; the Ring Battery Doorbell 2K (2nd Gen) closes the gap only if you already pay for its plan on other devices.
Pick by installation, not by brand
- Power at the mount: eufy Video Doorbell E340 runs on rechargeable battery; Ring Battery Doorbell 2K (2nd Gen) on rechargeable battery. A mount without the matching power rules a model out before any other spec matters.
- Where video lives: eufy Video Doorbell E340 records to 8 GB on the doorbell; Ring Battery Doorbell 2K (2nd Gen) to cloud plan required for recording. Local storage keeps recording when the plan lapses; a cloud-only model keeps only live view.
- The app you already use: eufy Video Doorbell E340 works with Alexa, Google Home; Ring Battery Doorbell 2K (2nd Gen) with Alexa. Shared ecosystems show live view and alerts, not every feature of the maker's app.
Related questions
Does the eufy Video Doorbell E340 need a subscription?
No. It records to 8 GB on the doorbell without a plan; a cloud plan is optional.
Does the Ring Battery Doorbell 2K (2nd Gen) need a subscription?
Yes. It saves video only with a paid plan; the cheapest plan that records costs $4.99 a month. Live view and alerts work without one.
Can I mix them in one home?
Yes, but each uses its own app unless both are added to a shared ecosystem such as Alexa or Google Home, and shared views there are more limited than in the maker's app. My list flags this when you add both.
Are these prices live?
No. They are recorded US list prices with a checked date; Canadian prices are recorded separately per model and never converted. Open a model page for its regional offers.
