eufy Security Video Doorbell E340 Review
Our verdict
The E340 is the doorbell to beat if you refuse to pay a monthly fee. Its second downward camera catches packages the main camera misses, and 8GB of onboard storage holds about a month of clips. Setup takes minutes on battery or existing wiring.
Pros and cons
What we like
- Dual cameras cover faces and doorstep packages
- No subscription required — local storage included
- Color night vision and 2K clarity
What could be better
- No continuous 24/7 recording option
- Package detection less refined than Ring's

Does the eufy E340 need a subscription?
No. Clips store on the doorbell's built-in 8GB storage (about 30 days), and live view, alerts, and two-way talk all work without any plan.
