What’s in the Box?

Before you begin, let’s make sure you have all the components. Open your Eufy C31 package and check for the following items:

• Eufy C31 Video Doorbell (main unit)
• Rechargeable battery pack (pre-installed)
• Mounting bracket (with screws and anchors)
• Angled wedge (for adjusting the camera angle)
• Security screw and tool
• USB charging cable
• Quick start guide

Everything should be neatly packed and ready to go. If anything is missing or damaged, contact Eufy customer support immediately. It’s always a good idea to charge the battery fully before installation—even though it comes partially charged, a full charge ensures optimal performance from day one.

Tools You’ll Need

One of the best things about the Eufy C31 is that it’s designed for easy DIY installation. You won’t need any special tools, but having these on hand will make the process smoother:

• Smartphone or tablet (iOS or Android)
• Drill (with a 1/4-inch drill bit)
• Screwdriver (Phillips head)
• Level (to ensure the doorbell is straight)
• Pencil (for marking drill holes)
• Ladder (if your doorbell location is high)

Optional but helpful: a stud finder (if mounting on brick or stucco), and a tape measure to confirm placement.

Pre-Installation Checklist

Taking a few minutes to prepare before you start drilling will save you time and frustration later. Follow this quick checklist:

1. Check Your Wi-Fi Signal

The Eufy C31 connects to your home Wi-Fi network to send video and alerts. It requires a 2.4 GHz Wi-Fi connection (it does not support 5 GHz). Use your smartphone to check the signal strength at your doorbell location. If the signal is weak, consider using a Wi-Fi extender or mesh network to boost coverage.

2. Download the Eufy Security App

The Eufy Security app is essential for setup, live viewing, and managing settings. Download it from the Apple App Store or Google Play Store. Create an account if you don’t already have one—this will be used to pair and control your doorbell.

3. Charge the Battery

Even though the battery comes partially charged, we recommend fully charging it before installation. Remove the battery pack from the doorbell (press the release button on the back), connect it to the USB cable, and plug it into a power source. A full charge takes about 4–6 hours and can last up to 180 days, depending on usage.

4. Choose the Right Location

Your doorbell should be mounted at a height of about 48 inches (4 feet) from the ground—this is the standard height for most doorbells and ensures the camera captures faces clearly. Avoid placing it too close to bright lights, which can cause glare, or in direct sunlight, which may affect image quality.

5. Decide on Mounting Type

The Eufy C31 offers two mounting options: vertical (straight on) or angled (using the wedge). Use the vertical mount if your door is flush with the wall. Use the angled wedge if your door is set back or you want a better view of the walkway. The wedge allows up to a 15-degree tilt.

Step-by-Step Installation Process

Now that you’re prepared, let’s get installing! Follow these steps carefully to mount and set up your Eufy C31 doorbell.

Step 1: Remove Your Old Doorbell (If Applicable)

If you’re replacing an existing wired doorbell, turn off the power at the circuit breaker to avoid electrical shock. Unscrew and remove the old doorbell unit. You don’t need to cap the wires—the Eufy C31 is battery-powered, so the old wiring can be left in place or tucked safely into the wall.

Pro Tip: Take a photo of the wiring before disconnecting, just in case you ever want to reinstall a wired doorbell.

Step 2: Install the Mounting Bracket

The mounting bracket is what holds your doorbell securely to the wall. Here’s how to install it:

• Hold the bracket (or bracket + wedge) against the wall at your desired height.
• Use a level to ensure it’s straight.
• Mark the screw holes with a pencil.
• Drill pilot holes using a 1/4-inch drill bit. If you’re mounting on brick, concrete, or stucco, use wall anchors for extra support.
• Secure the bracket to the wall using the provided screws and a screwdriver.

Note: If using the angled wedge, attach it to the bracket first, then mount the assembly to the wall.

Step 3: Attach the Doorbell to the Bracket

Once the bracket is secure, it’s time to attach the Eufy C31:

• Slide the doorbell onto the bracket from the top down.
• Push it firmly until it clicks into place.
• Use the security screw and tool to lock the doorbell to the bracket. This prevents theft—only someone with the tool can remove it.

Give the doorbell a gentle tug to make sure it’s securely mounted. You don’t want it falling off in the middle of the night!

Step 4: Power On and Connect to Wi-Fi

Now it’s time to bring your doorbell to life:

• Press and hold the power button on the back of the doorbell for 3 seconds until the LED light starts blinking blue.
• Open the Eufy Security app on your phone.
• Tap “Add Device” and select “Doorbell” from the list.
• Follow the on-screen instructions to scan the QR code on the back of the doorbell.
• Connect the doorbell to your 2.4 GHz Wi-Fi network by entering your password.

The app will guide you through the pairing process. It may take a minute or two for the doorbell to connect. Once connected, the LED will turn solid blue.

Step 5: Configure Settings in the App

With the doorbell online, it’s time to customize your experience:

• Motion Detection: Adjust sensitivity and set activity zones to reduce false alerts (e.g., from passing cars or trees).
• Notifications: Choose when and how you receive alerts (push notifications, email, etc.).
• Recording Settings: Enable continuous recording, motion-triggered recording, or person detection.
• Two-Way Audio: Test the microphone and speaker to ensure clear communication.
• Night Vision: The C31 has infrared night vision—make sure it’s enabled for 24/7 monitoring.

Take some time to explore the app’s features. You can also set up automations, like turning on smart lights when motion is detected.

Testing Your Eufy C31 Doorbell

Before you call the job done, it’s important to test everything to ensure it’s working correctly.

Test 1: Live View

Open the Eufy app and tap “Live View” to see the camera feed. Walk in front of the doorbell and check the video quality. Is the image clear? Can you see faces and packages? Adjust the angle if needed.

Test 2: Motion Detection

Walk across the detection zone and see if you receive a notification. If not, increase the sensitivity or widen the activity zone in the app.

Test 3: Two-Way Audio

Press the talk button in the app and speak. Ask someone to stand near the doorbell and confirm they can hear you clearly. Then, have them speak and check if you can hear them.

Test 4: Night Vision

Turn off the lights and check the live feed. The infrared LEDs should activate, providing a clear black-and-white image in the dark.

Test 5: Battery and Charging

Check the battery level in the app. If it’s low, remove the battery and recharge it using the USB cable. The app will notify you when the battery is running low.

Troubleshooting Common Issues

Even with careful installation, you might run into a few hiccups. Here’s how to fix the most common problems:

Issue: Doorbell Won’t Connect to Wi-Fi

Solution: Make sure you’re using a 2.4 GHz network (not 5 GHz). Move your router closer or use a Wi-Fi extender. Restart the doorbell and try pairing again.

Issue: Poor Video Quality

Solution: Clean the camera lens with a soft, dry cloth. Ensure the doorbell isn’t facing direct sunlight or bright lights. Adjust the angle for better lighting.

Issue: False Motion Alerts

Solution: Reduce motion sensitivity in the app. Draw activity zones to exclude areas like busy streets or swaying trees.

Issue: Doorbell Keeps Disconnecting

Solution: Check your Wi-Fi signal strength. Move the router or add a mesh extender. Update the doorbell firmware via the app.

Issue: Battery Drains Too Fast

Solution: Lower the recording resolution or disable continuous recording. Reduce motion sensitivity to limit triggers. Ensure the battery is fully charged.

Maintenance Tips for Long-Term Use

To keep your Eufy C31 performing at its best, follow these simple maintenance tips:

• Clean the lens monthly: Use a microfiber cloth to remove dust, dirt, or fingerprints.
• Check battery level regularly: The app sends low-battery alerts, but it’s good to check every few weeks.
• Update firmware: Eufy releases updates to improve performance and security—enable auto-updates in the app.
• Review recordings: Periodically check your event history to ensure everything is working as expected.
• Secure the doorbell: Make sure the security screw is tight to prevent tampering.
