TP-Link Tapo D225 Battery Doorbell vs eufy Video Doorbell E340: which should you buy?

Reviewed recording configurations

2 exact US configurations, 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.

Side by side

Manufacturer specifications and recorded list prices, not our tests. A blank or “Not published” cell means the maker does not state it; we never guess a figure.

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 TP-Link Tapo D225 Battery Doorbell is the cheaper way to own one doorbell for 3 years; the eufy Video Doorbell E340 closes the gap only if you already pay for its plan on other devices.

Pick by installation, not by brand

• Power at the mount: TP-Link Tapo D225 Battery Doorbell runs on rechargeable battery; eufy Video Doorbell E340 on rechargeable battery. A mount without the matching power rules a model out before any other spec matters.
• Where video lives: TP-Link Tapo D225 Battery Doorbell records to microSD card; eufy Video Doorbell E340 to 8 GB on the doorbell. Local storage keeps recording when the plan lapses; a cloud-only model keeps only live view.
• The app you already use: TP-Link Tapo D225 Battery Doorbell works with Alexa, Google Home; eufy Video Doorbell E340 with Alexa, Google Home. Shared ecosystems show live view and alerts, not every feature of the maker's app.
