Smart Display E10: More Than Just a Screen

The Smart Display E10 is the perfect companion to the Familock S3. It acts as a video doorbell, showing you a live feed of your front door whenever someone rings or triggers the motion sensor. The display has a built-in camera and speaker, allowing you to see and talk to visitors without opening the door. This is particularly useful for package deliveries or unexpected guests.

Beyond its doorbell function, the E10 serves as a central hub for your smart home. It can display notifications from other eufy devices, such as cameras and sensors, and even allow you to control them via the touchscreen.

Setting up the Smart Display E10 is equally simple. You just plug it in, connect it to your Wi-Fi, and pair it with the Familock S3 via the app. The app walks you through the process, and within minutes, you'll have both devices up and running.

Performance in Daily Use

In our testing, the Familock S3 performed flawlessly. The fingerprint sensor recognized our prints almost instantly, and the keypad was responsive. The auto-lock feature worked as expected, locking the door after we closed it. We also appreciated the ability to grant temporary access codes to guests or service providers, which we could revoke at any time from the app.

The Smart Display E10 was equally impressive. The video feed was clear, and the two-way audio had minimal lag, making conversations with visitors feel natural. The motion detection was accurate, sending notifications to our phones when someone approached the door. The display's battery backup ensured that we could still see who was at the door during a power outage, adding an extra layer of peace of mind.

  • Fast and accurate fingerprint recognition
  • Reliable auto-lock and temporary access codes

Comparing to Traditional Smart Locks

Traditional smart locks often come with a separate video doorbell, requiring two devices and two apps. The Familock S3 and Smart Display E10 combine these functions into a cohesive system, reducing clutter and simplifying your smart home setup. The integration between the two is seamless, with the display automatically showing the video feed when the doorbell rings.

Another advantage is the unified app experience. With the eufy Security app, you can manage both the lock and the display from one place, along with any other eufy devices you own. This centralization makes it easier to monitor and control your home security. While some might argue that separate devices offer more flexibility, the convenience of an all-in-one solution is hard to beat.

  • All-in-one solution reduces device clutter
  • Unified app for managing lock and display
  • Seamless integration between devices
