Frequently Asked Questions (FAQ)

When it comes to smart home security, you’ve probably got some questions. Here are some of the most common ones about eufy security systems, especially concerning the eufy entry sensor HomeBase 3 combination.

Q1: What is eufy HomeBase 3 (S380) and why is it important?
A1: The eufy HomeBase 3 (model S380) is the central hub for your eufy security system. It acts as the brain, connecting all your compatible eufy devices, storing local footage (with expandable storage up to 16TB), and enabling advanced AI features like BionicMind facial recognition. It’s crucial because it enhances the functionality of devices like the eufy entry sensor, allowing for smarter alerts, siren integration, and local data storage without monthly fees.

Q2: Are all eufy entry sensors compatible with HomeBase 3?
A2: Most modern eufy entry sensors are designed to be compatible with HomeBase 3. However, it’s always a good idea to double-check the product description or eufy’s official compatibility list to ensure seamless integration and access to all the HomeBase 3’s advanced features.

Q3: Do eufy security products, like the entry sensor or HomeBase 3, require monthly fees?
A3: One of the biggest advantages of eufy security products is their commitment to no monthly fees for essential functionalities. The HomeBase 3 comes with built-in storage and offers expandable local storage, meaning you won’t need to pay recurring subscriptions for video storage or basic alerts. There is an optional 24/7 professional monitoring service available if you desire that added layer of protection, but it’s not mandatory.

Q4: How does a eufy entry sensor work, and what kind of alerts does it provide?
A4: A eufy entry sensor consists of two parts: a main sensor and a magnet. When installed on a door or window frame, the sensor detects when the magnet separates (i.e., the door/window opens). It then sends an instant signal to your HomeBase. This triggers real-time notifications to your smartphone via the eufy Security app, and can also activate a loud 100-decibel siren on the HomeBase to deter intruders.

Q5: What is BionicMind AI, and how does it improve security?
A5: BionicMind is eufy’s advanced self-learning AI technology, primarily enabled by HomeBase 3. It significantly improves security by offering highly accurate facial recognition (up to 99.9%), allowing your system to distinguish between family members, friends, and strangers. This means fewer false alerts and more relevant notifications, as the system learns over time to identify important events and filter out irrelevant ones, making your security smarter and more efficient.

Q6: Is installing eufy entry sensors and other devices difficult for a DIYer?
A6: Not at all! Eufy products are generally designed for easy, DIY installation. Entry sensors typically use adhesive strips or a few screws, and setting them up with the HomeBase via the eufy Security app is very intuitive. Most users find the process straightforward, often taking only minutes per device.

Q7: Can I use eufy cameras or sensors without a HomeBase 3?
A7: Some eufy cameras (like certain SoloCams) can function independently without a HomeBase, storing footage on a microSD card. However, for devices like the eufy entry sensor, a HomeBase (either HomeBase 2 or HomeBase 3) is required for full functionality, including triggering sirens, receiving notifications, and recording events. Using HomeBase 3 unlocks the most advanced features, like BionicMind AI and expandable local storage.


Wrapping up, building a smart home security system with eufy is all about choosing the right components that work together seamlessly. Whether you’re starting with a foundational eufy entry sensor HomeBase 3 combination or expanding with smart cameras, doorbells, or leak detectors, eufy offers robust, user-friendly solutions that prioritize your privacy and pocketbook. With no monthly fees for essential features and cutting-edge AI, you’re not just buying security devices; you’re investing in peace of mind.
