Choosing Your Installation Method: Wired vs. Wireless
The Eufy Video Doorbell C31 is versatile—it can be installed in two ways: wired or wireless. Your choice depends on your home setup and preferences.
Wired Installation
If your home already has doorbell wiring (typically low-voltage, 16–24V AC), you can use it to power the doorbell continuously. This means no battery charging and reliable operation.
Pros:
– No need to charge the battery
– Always powered
– Can trigger mechanical chimes (with compatible transformers)
Cons:
– Requires existing wiring
– Slightly more complex installation
Wireless Installation
If you don’t have doorbell wiring or prefer a cleaner look without wires, go wireless. The C31 uses a rechargeable battery that lasts up to 180 days on a single charge (depending on usage).
Pros:
– Easy to install
– No wiring needed
– Can be placed almost anywhere
Cons:
– Battery needs periodic charging
– May not work with mechanical chimes (unless using the Eufy Chime Kit)
Tip: If you go wireless and want a chime, consider buying the Eufy Chime Kit (sold separately). It plugs into an outlet and rings when the doorbell is pressed.
Pre-Installation Checklist
Before you start drilling or wiring, do a quick prep:
- Check your Wi-Fi signal: Use your phone to test the signal strength at your door. The doorbell needs at least -70 dBm for stable video streaming. If weak, consider a Wi-Fi extender.
- Download the Eufy Security app: Available on the App Store (iOS) or Google Play (Android). Create an account if you don’t have one.
- Gather tools: You’ll need a screwdriver (Phillips #2), drill (if mounting on brick or concrete), level, and possibly a voltage tester (for wired setups).
- Turn off power (for wired installs): If replacing an existing doorbell, turn off the circuit breaker that powers it. Use a voltage tester to confirm it’s off.
Step 1: Install the Mounting Bracket
The mounting bracket holds the doorbell securely. You can choose between a flat or angled bracket depending on your door and wall setup.
Choose the Right Bracket
– Use the flat bracket if your doorbell will be mounted straight on the wall.
– Use the angled bracket (15° or 30°) if you want to tilt the camera toward the walkway for better motion detection.
Mark the Mounting Holes
1. Hold the bracket against the wall where you want to install the doorbell.
2. Use a level to ensure it’s straight.
3. Mark the screw holes with a pencil.
Tip: The ideal height is about 48 inches (4 feet) from the ground—eye level for most visitors.
Drill and Secure the Bracket
1. Drill pilot holes at the marked spots (use a masonry bit if drilling into brick or concrete).
2. Insert wall anchors if needed.
3. Screw the bracket into place using the provided screws.
Make sure it’s tight and secure—this will hold your doorbell firmly.
Step 2: Wired Installation (Using Existing Doorbell Wiring)
If you’re using existing wiring, follow these steps carefully.
Turn Off Power
1. Go to your electrical panel and turn off the breaker that controls your doorbell.
2. Remove the old doorbell and disconnect the wires.
3. Use a voltage tester to confirm no power is flowing.
Connect the Wires
1. Strip about 1/4 inch of insulation from the ends of the wires.
2. Loosen the terminal screws on the back of the Eufy doorbell.
3. Insert the wires into the terminals (usually labeled “Front” and “Trans”).
4. Tighten the screws to secure the wires.
Note: The C31 is compatible with most standard doorbell transformers (16–24V AC). If your chime doesn’t ring after installation, you may need a resistor (included in some kits) or a compatible transformer.
Attach the Doorbell to the Bracket
1. Slide the doorbell onto the mounting bracket.
2. Push it down until it clicks into place.
3. Use the security screw and tool to lock it in (prevents theft).
Step 3: Wireless Installation (Battery-Powered)
If you’re going wireless, the process is simpler—no wiring needed.
Charge the Battery
1. Remove the doorbell from the box.
2. Use the USB-C cable to charge the battery fully (takes about 4–6 hours).
3. A green light indicates a full charge.
Attach the Doorbell to the Bracket
1. Slide the charged doorbell onto the mounting bracket.
2. Push down until it clicks.
3. Secure with the security screw.
Optional: Install the Solar Panel
To keep the battery charged continuously, you can install the optional Eufy Solar Panel:
1. Mount the solar panel near the doorbell (within 10 feet).
2. Connect the cable to the doorbell’s charging port.
3. Position the panel to face direct sunlight.
This is great for high-traffic areas or if you don’t want to charge the battery every few months.
Step 4: Download and Set Up the Eufy Security App
The Eufy app is essential for configuring your doorbell, viewing live video, and receiving alerts.
Download the App
1. Open the App Store (iOS) or Google Play (Android).
2. Search for “Eufy Security” and download the official app.
3. Open the app and create an account (or log in if you already have one).
Add Your Doorbell
1. Tap the “+” icon in the app.
2. Select “Video Doorbell” and then “C31.”
3. Follow the on-screen instructions.
Scan the QR Code
1. Remove the doorbell from the bracket (if needed).
2. Locate the QR code on the back of the device.
3. Hold your phone close and scan it with the app.
The app will detect the doorbell and begin setup.
Connect to Wi-Fi
1. Select your home Wi-Fi network.
2. Enter the password.
3. Wait for the doorbell to connect (this may take 1–2 minutes).
Tip: Use a 2.4 GHz Wi-Fi network. The C31 does not support 5 GHz.

3. Draw zones where you want alerts (e.g., walkway, driveway).
4. Avoid areas like busy streets to reduce false alerts.
Two-Way Audio
Test the microphone and speaker:
1. Press the doorbell button (or simulate a press in the app).
2. Speak into your phone—you should hear yourself through the doorbell.
3. Tap the talk button in the app to speak to someone at the door.
Night Vision and Video Quality
The C31 has infrared night vision. To adjust:
1. Go to “Video Settings.”
2. Choose “Night Vision” mode (Auto, On, or Off).
3. Set video resolution to 2K for the clearest image.
Local Storage (No Cloud Fees)
The C31 records to a microSD card (sold separately) or uses onboard storage. To set up:
1. Insert a microSD card (up to 128GB, Class 10 recommended).
2. Format it in the app under “Storage Settings.”
3. Choose recording mode: Continuous, Motion-Only, or Scheduled.
Note: Local storage means no monthly subscriptions—your videos stay private and secure.
Step 6: Test the Doorbell
Before calling it a day, test everything:
- Press the doorbell button—does it ring (if wired) or send a notification (if wireless)?
- Open the app and check the live view—is the video clear?
- Walk in front of the doorbell—do you get a motion alert?
- Speak through the app—can you hear and be heard?
- Check night vision—turn off the lights and see if the image is visible.
