Before you touch a single wire, make sure you have the right tools and materials. Having everything ready will save you time and frustration.
Tools and Materials
- Xfinity doorbell kit (includes doorbell, mounting bracket, screws, and wire nuts)
- Screwdriver (Phillips and flathead)
- Drill and drill bits (if mounting on brick, stucco, or concrete)
- Voltage tester (to confirm power is off)
- Wire strippers (if you need to trim or expose wires)
- Smartphone or tablet with the Xfinity app installed
- Ladder (if your doorbell is mounted high)
- Electrical tape (optional, for extra wire protection)
Check Your Existing Setup
If you’re replacing an old doorbell, take a moment to inspect the current wiring. Most Xfinity doorbells work with standard low-voltage doorbell systems (16–24 volts). If your home has a mechanical chime, it should be compatible. However, if you have a digital or wireless chime, you may need to adjust settings or use a compatible chime module (more on that later).
Also, check the condition of the wires. Frayed or corroded wires should be trimmed and stripped to expose fresh copper. If the wires are too short, you may need to extend them carefully.
Step 1: Turn Off the Power
Safety first! Working with electrical wiring can be dangerous if the power is on. Even though doorbell systems use low voltage, it’s still important to turn off the power to avoid shocks or short circuits.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “doorbell,” “chime,” or “front door.” If there’s no label, you may need to test breakers by turning them off one at a time and checking if the doorbell stops working.
Turn Off the Breaker
Switch the breaker to the “off” position. Use a voltage tester on the doorbell wires to confirm there’s no power. Touch one probe to each wire—if the tester doesn’t light up or beep, you’re safe to proceed.
Label the Wires (Optional but Helpful)
If you’re replacing an old doorbell, the two wires connected to it are usually labeled “Front” and “Trans” (transformer). Use a piece of tape to label them so you know which is which when reconnecting. This prevents confusion later.
Step 2: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, you’ll need to remove it before installing the Xfinity model.
Unscrew the Old Doorbell
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the doorbell away from the wall, exposing the two wires underneath.
Disconnect the Wires
Loosen the terminal screws or remove the wire nuts to disconnect the wires. Be careful not to let the wires slip back into the wall. You can tape them to the wall temporarily to keep them in place.
Remove the Old Mounting Plate
If the old doorbell had a mounting plate or bracket, unscrew and remove it. You’ll be replacing it with the Xfinity mounting bracket.
Step 3: Install the Xfinity Mounting Bracket
The mounting bracket is what holds your Xfinity doorbell securely to the wall. Proper installation ensures stability and prevents damage from wind or tampering.
Position the Bracket
Hold the Xfinity mounting bracket against the wall where you want to install the doorbell. Make sure it’s level using a spirit level. The ideal height is about 48 inches from the ground—eye level for most visitors.
Mark the Screw Holes
Use a pencil to mark the spots where the screws will go. If you’re mounting on wood or siding, you can screw directly into the surface. For brick, stucco, or concrete, you’ll need to drill pilot holes and use wall anchors.
Drill and Secure the Bracket
Drill pilot holes if needed, then screw the bracket into place using the provided screws. Make sure it’s tight and doesn’t wobble. A loose bracket can cause the doorbell to shift or fall.
Route the Wires Through the Bracket
Feed the two doorbell wires through the center hole in the mounting bracket. This keeps them neat and protected.
Step 4: Connect the Wires to the Doorbell
Now it’s time to connect the wires to your Xfinity doorbell. This step is crucial for power and functionality.
Identify the Wire Terminals
On the back of the Xfinity doorbell, you’ll see two terminals labeled “Front” and “Trans.” These correspond to the two wires from your wall. It doesn’t matter which wire goes to which terminal—doorbell polarity isn’t critical.
Strip the Wire Ends (If Needed)
If the wire ends are frayed or too short, use wire strippers to remove about 1/4 inch of insulation. You want clean, exposed copper to make a solid connection.
Attach the Wires
Loosen the terminal screws on the doorbell, insert each wire into its corresponding terminal, and tighten the screws securely. Make sure the wires are snug and won’t come loose.
Secure with Wire Nuts (Optional)
For extra safety, you can twist the wires together and cover them with a wire nut, then tape it with electrical tape. This is especially helpful in areas with high wind or vibration.
Step 5: Attach the Doorbell to the Bracket
With the wires connected, it’s time to mount the doorbell itself.
Align the Doorbell
Hold the Xfinity doorbell against the mounting bracket. The bottom of the doorbell should snap into place, and the top should align with the screw hole.
Secure with the Security Screw
Use the small security screw (usually included in the kit) to fasten the top of the doorbell to the bracket. This prevents theft or tampering. Tighten it just enough—don’t over-tighten and risk cracking the plastic.
Check for Stability
Give the doorbell a gentle tug to make sure it’s firmly attached. It shouldn’t move or wobble. If it does, double-check the bracket and screw.
Step 6: Turn the Power Back On
Now that everything is connected, it’s time to restore power and test the system.
Flip the Breaker
Go back to your electrical panel and turn the doorbell breaker back on.
Wait for the Doorbell to Power Up
The Xfinity doorbell should light up and begin initializing. You may see a spinning light or hear a chime. This can take 30–60 seconds.
Listen for the Chime
Press the doorbell button. You should hear a chime inside your home. If you don’t, there may be a wiring issue or a problem with the chime unit.
Step 7: Set Up the Xfinity App
The Xfinity app is essential for configuring your doorbell, connecting it to Wi-Fi, and customizing settings.
Download the App
If you haven’t already, download the “Xfinity” app from the Apple App Store or Google Play Store. Log in with your Xfinity account credentials.
Start the Setup Process
Open the app and tap “Add Device” or “Set Up New Device.” Select “Doorbell” from the list of options.
Scan the QR Code
The app will prompt you to scan the QR code on the back of your doorbell. Use your phone’s camera to scan it. This links the device to your account.
Connect to Wi-Fi
Follow the on-screen instructions to connect your doorbell to your home Wi-Fi network. Make sure you’re using a 2.4 GHz network—Xfinity doorbells don’t support 5 GHz.
Name Your Doorbell
Give your doorbell a name, like “Front Door” or “Main Entrance,” so you can identify it easily in the app.
Adjust Settings
Customize motion zones, notification preferences, video quality, and recording options. You can also set up smart alerts for packages, people, or vehicles.
Step 8: Test the Doorbell
Before you call the job done, test everything to make sure it’s working properly.
Test the Button
Press the doorbell button. You should hear the chime inside and receive a notification on your phone.
Check the Video Feed
Open the Xfinity app and view the live video feed. Make sure the image is clear, the night vision works, and the audio is crisp.
Test Two-Way Audio
Speak through the app and listen for your voice on the doorbell. Then, speak near the doorbell and check if you can hear it in the app.
Verify Motion Detection
Walk in front of the doorbell to trigger motion alerts. Adjust the sensitivity if it’s too sensitive or not sensitive enough.
