Does the eufy Security Video Doorbell E340 require a monthly subscription?
No. The E340 stores video locally on 8GB of built-in eMMC storage, and eufy markets it as no subscription and no monthly fee, ever. Skipping a required subscription is one of the main reasons to choose it over Ring.
Is the E340 good value, and how does it hold up day to day?
Largely, yes. Video is clear, installation is easy and there is no required subscription, which puts it ahead of Ring for many households. Battery life and connectivity are less dependable, and with two cameras running the battery can drain faster than you might expect, so a spare battery to swap in is worth considering. Most of the value comes from the storage: with no monthly fee, what you pay at checkout is the whole cost.
Does the E340 need to be hardwired, or can it run on battery only?
Both options are supported. It can run wireless on a quick-release rechargeable battery that swaps in seconds for a zero-downtime install, or be wired to a 16 to 24 volt doorbell supply for a permanent connection that keeps the battery topped up. At 1 watt it is a low-draw device, well suited to trickle charging from doorbell wiring. It screws onto a standard wall mount, so there is no specialty bracket or extra hardware to buy.
What's the difference between the two cameras on the E340?
eufy describes one forward-facing camera that captures visitors head-to-toe at the door, and a second downward-angled camera aimed at the doorstep itself, mainly to catch packages left below the door's normal sightline. The viewing angle is 160 degrees, video is captured at 2K with an effective still resolution of 1440 pixels, and the doorbell runs two channels, one per camera. That two-view setup is the main advantage over a single-camera doorbell.
Do I need to buy a separate chime to hear alerts inside my house?
Possibly. eufy says the E340 can connect with an existing mechanical chime, or pair with eufy's own HomeBase 2 (S280), HomeBase 3 (S380) or Minibase Chime, sold separately. Out of the box, ring and motion alerts go to your phone through the app, and the doorbell works with Amazon Alexa and Google Assistant devices. An audible chime beyond your phone needs a mechanical chime, a smart speaker or an added eufy accessory, a real cost if you have none of those.
How does the E340 perform in the dark, and is it rated for outdoor weather?
eufy markets a dual-light color night vision system rather than a switch to black-and-white infrared, with a night vision range of 16 feet and two IR LEDs. It carries an IP65 waterproof rating, appropriate for a device mounted outdoors and exposed to rain. Night vision is a strong point, helped by two bright spotlights on the lower camera that light up the doorstep.
