The eufy E340 Video Doorbell delivers complete entryway coverage through two cameras working in tandem. The front-facing wide-angle camera captures visitors from head to toe, while the downward-facing camera fills in the blind spot to monitor packages placed at the door. Both cameras record in 2K Full HD resolution (2688 x 1520), providing sharp, detailed visuals of anyone who approaches.

Color night vision uses an industry-first dual-light system paired with advanced light-capturing algorithms, delivering clear nighttime viewing up to 16 feet with less motion blur than previous generations. On-device AI accurately identifies human presence to minimize false alerts, and the Delivery Guard feature specifically monitors for package arrivals and theft. All footage is saved to 8GB of built-in local storage — enough for approximately 60 days of event recordings — with no monthly cloud subscription fees required.

Installation is flexible: use battery mode for a tool-free setup or connect to an existing 8–24V wired doorbell for continuous power topped off by the battery. Two-way audio lets you speak with visitors in real time, with six preset Quick Replies available for convenient hands-free responses. The doorbell works with Amazon Alexa and Google Assistant for voice control, and pairs with a chime for audible alerts throughout your home. Compatible with eufy HomeBase S380, HomeBase S280, and Minibase Chime (T8023) for broader smart home security integration. Rated IP65 waterproof for all-weather outdoor use. Covered by a 1-year manufacturer warranty.
