eufy Security Offcial Renewed Video Doorbell E340
Dual Cameras, Double Security: Two cameras work together to deliver advanced viewing. The front-facing camera focuses on people, while the downward-facing camera fills in the gaps with a view of the floor in front of your door.
Color Night Vision for a Clear View : Introducing the industry's first dual-light system paired with an advanced light capturing and processing algorithm. Less blur than previous iterations of night vision and a clear nighttime viewing distance of up to 16ft (5m).
See What Matters in 2K Full HD Clarity: 2K clarity reveals more details. Get clear and detailed visuals of your doorstep and anyone who drops by.
Battery or Wired, Your Choice: Battery mode makes installation easy. Keep a spare quick-release battery for quick swaps and avoiding downtime due to charging. Wired mode is also powered by the battery, which is topped up by the wired power source for long-lasting performance. Note: Wired mode requires the battery to be installed and a power source power should be connected with 16 to 24V and >10VA.
Pair with a Chime to Hear Alerts Throughout Your Home: Can connect with your existing chime, or pair with eufy HomeBase S280, eufy HomeBase S380, eufy Minibase Chime (T8023), Alexa devices, and Google Voice Assistant devices.
