Dual-Camera Doorbell for Package Protection

The eufy E340 battery video doorbell uses two cameras to cover both visitors and the floor area in front of the door. It records in 2K resolution and adds colour night vision up to 16 ft using a dual-light system. The unit works with Alexa and Google Assistant and stores footage locally without a monthly fee.

Quick-Release Battery or Low-Voltage Wiring

Battery mode allows wire-free mounting and the quick-release pack can be swapped in seconds to avoid downtime. Wired installation is also available but requires the battery to stay fitted and a 16 to 24 V supply rated above 10 VA. The device will not operate on wired power alone if the battery is removed.

Suits Homes Wanting Local Storage and Wide Coverage

This model fits owners who want dual-angle monitoring and no subscription charges. It is not suited for buyers who need compatibility with the original eufy Wi-Fi Chime T8020 or Chime T8740 and T8742. Users without an existing low-voltage doorbell circuit must rely on battery charging.

Questions about this item

How do I verify the dual cameras on the E340 are both recording correctly after installation?

Open the eufy Security app and check the live view; the front camera shows visitors while the downward camera covers the floor area up to 16 ft away at night, confirming both lenses are active.

What comes in the box with the E340 and what must I purchase separately for wired power?

The doorbell includes a quick-release battery; for wired operation you must supply a 16 to 24 V transformer rated above 10 VA and keep the battery installed.

Which HomeBase or chime models work with the E340 for local alerts and storage?

Compatible devices are HomeBase S280, HomeBase S380, and Minibase Chime T8023; the original Wi-Fi Chime T8020 and Chime models T8740 and T8742 are not supported.
