Before you begin, gather all the tools and materials you’ll need. Having everything ready will save time and prevent frustration mid-installation.
You’ll need:
- Your Xfinity Video Doorbell (included in the box)
- Screwdriver (usually Phillips head)
- Drill and drill bits (if mounting on brick, stucco, or concrete)
- Level (the kit includes a small one, but a larger one helps)
- Smartphone or tablet with the Xfinity Home app installed
- Wi-Fi network name (SSID) and password
- Voltage tester (optional but recommended)
- Wire strippers (if you need to trim or re-strip wires)
- Ladder (if your doorbell is mounted high)
Also, make sure your existing doorbell system is compatible. The Xfinity Video Doorbell requires a transformer that outputs 16–24 volts AC and at least 20 volt-amperes (VA). Most modern doorbells meet this, but older homes might need an upgrade. If you’re unsure, check the label on your current doorbell transformer (usually located near your doorbell chime or in the electrical panel).
Step 1: Turn Off the Power
Safety first! Before touching any wires, you must turn off the power to your doorbell circuit. This prevents electric shock and protects your equipment.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (breaker box). Look for a breaker labeled “doorbell,” “chime,” or something similar. If there’s no label, you may need to test each breaker by turning them off one at a time and checking if your doorbell stops working.
Turn Off the Correct Breaker
Once you’ve identified the right breaker, switch it to the “OFF” position. Use a non-contact voltage tester at the doorbell location to confirm there’s no power. Simply touch the tester near the wires—if it doesn’t beep or light up, you’re safe to proceed.
Pro Tip: Place a piece of tape over the breaker switch so no one accidentally turns it back on while you’re working.
Step 2: Remove Your Old Doorbell
Now that the power is off, it’s time to remove your existing doorbell button.
Unscrew the Faceplate
Use your screwdriver to remove the screws holding the old doorbell faceplate to the wall. Gently pull the faceplate away from the wall. You should see two wires connected to the back.
Disconnect the Wires
Loosen the terminal screws or release the wire clips to disconnect the two wires. Don’t let them fall back into the wall—tape them to the wall or hold them with a clamp so they stay accessible.
Note: Label the wires if possible (e.g., “Front” and “Transformer”) to avoid confusion later. However, most doorbells are not polarity-sensitive, so it usually doesn’t matter which wire goes where.
Inspect the Wiring
Check the condition of the wires. If they’re frayed, corroded, or too short, you may need to strip fresh ends or extend them. Use wire strippers to remove about 1/4 inch of insulation from each wire if needed.
Step 3: Check Voltage and Compatibility
Before installing the new doorbell, verify that your electrical system can support it.
Test the Voltage
Use a multimeter or voltage tester to check the voltage across the two doorbell wires. Set your meter to AC voltage and touch the probes to each wire. You should see a reading between 16 and 24 volts. If it’s below 16V, your transformer may be too weak, and the doorbell might not work reliably.
Upgrade if Necessary
If your voltage is too low, consider upgrading your transformer. This is a job for a licensed electrician if you’re not comfortable working with electrical systems. A 16V or 24V, 20–40VA transformer is ideal for smart doorbells.
Example: If your old doorbell used a 10V transformer, it won’t power the Xfinity Video Doorbell properly. Upgrading ensures stable performance and prevents frequent disconnections.
Step 4: Install the Mounting Bracket
The Xfinity Video Doorbell comes with a mounting bracket that holds the device securely to your wall.
Position the Bracket
Hold the bracket against the wall where you want to install the doorbell. Use a level to make sure it’s straight. 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 you’ll drill. If you’re mounting on wood or drywall, you can screw directly into the surface. For brick, stucco, or concrete, you’ll need wall anchors and a drill.
Drill and Secure
Drill pilot holes at the marked spots. Insert wall anchors if needed, then screw the bracket into place using the included screws. Make sure it’s tight and level.
Tip: If your wall is uneven, use the included wedge (if provided) to adjust the angle so the camera points straight ahead.
Step 5: Connect the Wires
Now it’s time to connect your doorbell wires to the new device.
Attach Wires to the Bracket
Most Xfinity Video Doorbell brackets have two terminal screws or spring-loaded clips. Loosen the screws or press the clips open, then insert each wire. Tighten the screws or release the clips to secure the wires.
Important: The wires don’t have positive and negative poles, so it doesn’t matter which wire goes to which terminal.
Double-Check Connections
Give each wire a gentle tug to ensure it’s secure. Loose connections can cause power issues or intermittent operation.
Step 6: Attach the Doorbell to the Bracket
With the wires connected, it’s time to mount the doorbell itself.
Align and Slide
Hold the Xfinity Video Doorbell so the back aligns with the mounting bracket. Slide it down until it clicks into place. You should feel it lock securely.
Secure with Screw (if applicable)
Some models include a small security screw to prevent theft. If yours has one, use the provided Allen wrench to tighten it into the bottom of the doorbell.
Step 7: Restore Power and Test
Now that everything is connected, it’s time to turn the power back on.
Turn On the Breaker
Go back to your electrical panel and flip the breaker back to the “ON” position. Wait a few seconds for the doorbell to power up.
Check for Lights
The Xfinity Video Doorbell should light up with a solid or blinking LED. A solid light usually means it’s powered and ready to connect. A blinking light may indicate it’s searching for Wi-Fi or waiting for setup.
Note: If the light doesn’t come on, double-check your wiring and voltage. A loose wire or low voltage could be the culprit.
Step 8: Set Up the Xfinity Home App
The Xfinity Home app is your control center for the doorbell. It handles pairing, Wi-Fi setup, and customization.
Download and Open the App
If you haven’t already, download the “Xfinity Home” app from the Apple App Store or Google Play. Open it and sign in with your Xfinity account.
Add a New Device
Tap the “+” or “Add Device” button. Select “Video Doorbell” from the list. The app will guide you through the setup process.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the doorbell or in the app. This pairs the device with your account.
Connect to Wi-Fi
Enter your Wi-Fi network name (SSID) and password. The doorbell will attempt to connect. Make sure your phone is on the same 2.4 GHz network—most smart doorbells don’t support 5 GHz.
Tip: If connection fails, move closer to your router or use a Wi-Fi extender. A strong signal is crucial for smooth video and alerts.
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, alert sensitivity, night vision, and recording preferences. You can also set up two-way audio and enable person detection.
Step 9: Test All Features
Once setup is complete, test everything to make sure it’s working properly.
Check Live Video
Open the app and tap on your doorbell to view the live feed. Make sure the image is clear and the field of view covers your desired area.
Test Motion Alerts
Walk in front of the doorbell to trigger a motion alert. You should receive a notification on your phone within a few seconds.
Try Two-Way Audio
Press the talk button in the app and speak. Ask someone near the doorbell to listen. You should be able to hear each other clearly.
Ring the Doorbell
Press the button on the doorbell. Your chime should sound, and you should get a notification. If you have an Xfinity Chime, it will sync automatically.
