Community Reviews

The Eufy E340 is a wired or battery doorbell camera that stands out for strong motion detection and the appeal of no subscription. It can replace a Ring doorbell, and the included battery makes installation flexible. The main tradeoff is that wired use does not provide 24,7 continuous recording, and battery life drops to weeks when person detection is enabled, with recharge times around four hours. Storage is also limited without a HomeBase, and cold weather can cause reliability problems.

Common Questions (5)

  • No. The E340 does motion detection when wired, but it does not offer 24/7 continuous recording in wired mode. If continuous recording is the priority, this model does not provide it.

  • With person detection turned off, the battery can last months; with person detection enabled, it can drop to weeks and then take hours to recharge. Buying a spare battery can reduce downtime during swaps.

  • Yes. It can be hardwired or used with the included battery, so it works as either a wired or battery-powered doorbell.

  • The built-in storage is limited, and about 2GB is cited as only decent if you add a HomeBase. If you want more local storage, pairing it with a HomeBase is the practical route.

  • It can stop working in extremely cold conditions, and notifications or recordings may become inconsistent even when the transformer and specs are correct. That makes winter performance a concern in very cold climates.

That's $10 more expensive than buying them separately.

so the storage on these are pretty low? I read that you need to get a homebase for it if you want any decent storage (2gb).

I'm sorry but these are trash. They straight up stop working in any extremely cold conditions, think every eastern winter. Inconsistent notification and recording at best, even with the correct transformer and everything in spec. Not worth it at any price.
