eufy Video Doorbell E340

Compiled by SmartHomeWorkflow Research · eufy · Cameras & Doorbells · ~$149.99 (at time of research — never treated as a live price. $149.99 is eufy's own US list price for the battery-powered E340 (SKU T8214111), read 2026-08-09.)

Compatibility

Protocols: WIFI^[3]

What it can do^[11]

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[2][4]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

No subscription — local storage on HomeBase or SD

Maintenance reality^[3]

• Batteries: built-in rechargeable — expect roughly 4 months per set
• Works without the internet: Not established — we have not sourced this yet. It does not mean the product fails without the internet.
• Dual-cam design; local storage means YOU manage retention

Security updates^[9]

eufy publishes no security-update support date for this model. That is a gap in what the manufacturer has published, not evidence either way — some makers declare a support period and some say nothing at all.

eufy states that this product meets the UK's connected-device security rules, but publishes no date for how long it will issue security updates — and publishing that date is part of what those rules ask for. So there is no end date to show you here, and no way for you to check one.

The catch

No Apple Home — eufy promised HomeKit but its own product page still says it's unsupported; treat it as an Alexa/Google doorbell.

Who it's for

For buyers who want dual cameras (face + package view) with no monthly fee and local storage.
