Facial Recognition Unlocking: eufy Smart Lock E40 uses facial recognition to provide a faster, more effortless way to unlock your front door. Designed for everyday use, it offers a more natural keyless entry experience for the whole family. It works reliably across a wide range of users and everyday look changes, while all facial data is stored locally for complete privacy.

All-in-One Device: combines a 2K HD camera, doorbell, and smart lock to keep every moment in sight and your home secure. The 2K camera delivers clear details day and night, while the 135° head‑to‑toe view provides full‑body coverage for easy monitoring of visitors and deliveries.

Dual Power Supply: Stay powered with a 15,000mAh rechargeable lithium battery offering up to 6 months of full functionality, and an 800mAh built-in backup battery that automatically activates when power is low, ensuring uninterrupted operation.

Easy Installation: Easy DIY installation with no drilling needed for most doors. Compatible with most standard US and Canadian single‑cylinder deadbolts (not for round or non‑standard faceplates, or mortise locks). IP65 waterproof and suitable for use in ‑22℉ to 158℉ temperatures.

32GB Local Storage, No Monthly Fee: Keep your footage stored locally with built-in 32GB storage for convenient access and added privacy. There’s no monthly subscription required, giving you a smarter security solution with more control over your data and no ongoing fees.

Seamless Smart Home Integration: Easily integrates with the eufy Ecosystem and HomeBase 3 for advanced AI security features. Supports Matter for smooth, secure connections with Apple Home, Google Home, Alexa, and SmartThings—giving you a privacy-first, future-ready smart home experience. Note: Camera streams are not supported via Matter due to current limitations. For full features and the best experience, please use the eufy app.

High-Precision Radar, Fewer False Alerts: 60 GHz radar accurately detects human motion while filtering out pets, small objects, and wind interference. This helps deliver precise real-time alerts while reducing unnecessary notifications and extending battery life.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $33 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for eufy Security products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
