Before diving into installation, gather the right tools and materials. Having everything ready saves time and prevents mid-project trips to the hardware store.
Here’s what you’ll need:
- Blink Wired Doorbell kit: Includes the doorbell unit, mounting plate, screws, and wire connectors.
- Screwdriver (Phillips and flathead): For removing old doorbell and securing the new mount.
- Voltage tester: To confirm power is off and check transformer voltage.
- Wire strippers: For trimming and preparing existing doorbell wires.
- Drill and drill bits (optional): If you need to create new mounting holes or run wires.
- Level: To ensure your doorbell is straight.
- Smartphone with Blink app installed: Available on iOS and Android.
- Wi-Fi network: 2.4 GHz band required (5 GHz not supported).
Pro tip: If your current doorbell has very short wires, consider using wire extenders or fish tape to pull longer wires through the wall.
Step 1: Check Compatibility and Power Requirements
Not all doorbell systems are compatible with the Blink Wired Doorbell. Before you start, verify that your existing setup meets the requirements.
Check Your Transformer Voltage
The Blink Wired Doorbell requires a transformer that outputs between 8 and 24 volts AC. Most older doorbells use 16V, which works perfectly. However, some very old homes may have 6V or 12V transformers—still within range. Avoid systems over 24V, as they can damage the doorbell.
To check:
- Turn off power at the circuit breaker.
- Remove your existing doorbell button.
- Use a voltage tester to measure the voltage across the two wires.
If the voltage is outside the 8–24V range, you may need to replace the transformer. Consult an electrician if you’re unsure.
Verify Wi-Fi Signal Strength
Since the Blink doorbell relies on Wi-Fi for video streaming and alerts, ensure your front door area has a strong 2.4 GHz signal. You can use a Wi-Fi analyzer app to check signal strength. If it’s weak, consider installing a Wi-Fi extender near the door.
Check Existing Wiring
The Blink Wired Doorbell uses two wires: one for power and one for the doorbell circuit. Most homes have this setup. If your doorbell has only one wire or uses a wireless chime, you may need additional wiring or a compatible chime module.
Step 2: Turn Off the Power
Safety first! Working with electricity can be dangerous if you skip this step.
Locate Your Circuit Breaker
Find the breaker that controls your doorbell. It’s often labeled “doorbell,” “chime,” or “front door.” If not labeled, turn off breakers one by one and test the doorbell until it stops working.
Confirm Power Is Off
After turning off the breaker:
- Press your existing doorbell button—it shouldn’t ring.
- Use a non-contact voltage tester near the wires to ensure no current is present.
Never assume the power is off. Always double-check with a tester.
Step 3: Remove the Old Doorbell
Now it’s time to remove your existing doorbell button.
Unscrew the Old Button
Use a screwdriver to remove the screws holding the old doorbell in place. Gently pull the button away from the wall.
Disconnect the Wires
You’ll see two wires connected to the back. Loosen the terminal screws and carefully remove the wires. Don’t let them fall back into the wall.
Pro tip: Twist the wire ends slightly to keep them from fraying. If the wires are too short, use wire nuts to extend them.
Inspect the Mounting Area
Check the condition of the wall and mounting holes. If the old doorbell was loose or the wall is damaged, repair it before installing the new one.
Step 4: Prepare the Wires
Proper wire preparation ensures a solid connection.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch of insulation from each wire end. This exposes fresh copper for a better connection.
Twist the Exposed Copper
Gently twist the exposed strands to keep them neat and prevent fraying.
Secure Loose Wires
If the wires are too short or keep slipping back, use electrical tape to temporarily tape them to the wall or use a wire puller to extend them.
Step 5: Install the Mounting Plate
The mounting plate holds the Blink doorbell securely in place.
Position the Plate
Hold the mounting plate against the wall where you want the doorbell. Use a level to ensure it’s straight. The ideal height is between 48 and 60 inches from the ground—eye level for most visitors.
Mark the Screw Holes
Use a pencil to mark where the screws will go. If the holes don’t align with existing ones, you may need to drill new ones.
Drill Pilot Holes (If Needed)
If drilling new holes, use a drill bit slightly smaller than your screws. For brick or concrete, use a masonry bit and wall anchors.
Secure the Plate
Attach the mounting plate using the provided screws. Make sure it’s tight and level.
Step 6: Connect the Wires
Now it’s time to connect the wires to the Blink doorbell.
Identify the Terminals
On the back of the Blink doorbell, you’ll see two terminals labeled “Front” and “Trans.” These correspond to the two wires from your wall.
Attach the Wires
Loosen the terminal screws, insert one wire into each terminal, and tighten the screws. It doesn’t matter which wire goes where—the Blink doorbell is non-polarized.
Pro tip: If the wires are thin or fragile, use wire connectors (included) for a more secure connection.
Double-Check Connections
Ensure both wires are firmly attached and not touching each other. Loose connections can cause power issues or intermittent operation.
Step 7: Attach the Blink Doorbell
With the wires connected, it’s time to mount the doorbell.
Align the Doorbell
Hold the Blink doorbell against the mounting plate. The hooks on the back should align with the slots on the plate.
Slide It Into Place
Gently slide the doorbell down until it clicks into place. You should hear a secure snap.
Secure with Screw (If Applicable)
Some models include a security screw to prevent tampering. If yours has one, use a screwdriver to tighten it at the bottom.
Step 8: Restore Power and Test
Now that everything is installed, it’s time to power up.
Turn the Breaker Back On
Go to your circuit breaker and turn the doorbell circuit back on.
Wait for the Doorbell to Power Up
The Blink doorbell should light up within 30 seconds. A solid blue light indicates it’s receiving power and ready to connect.
Test the Button
Press the doorbell button. You should hear a chime (if connected to a chime) and see the light flash.
If nothing happens, double-check your wiring and power supply.
Step 9: Set Up the Blink App
The final step is syncing your doorbell with the Blink app.
Open the Blink App
Launch the Blink app on your smartphone. If you don’t have it, download it from the App Store or Google Play.
Log In or Create an Account
Sign in with your existing Blink account or create a new one.
Add a New Device
Tap the “+” icon and select “Add Device.” Choose “Doorbell” and then “Wired Doorbell.”
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the doorbell or inside the app.
Connect to Wi-Fi
Follow the prompts to connect your doorbell to your 2.4 GHz Wi-Fi network. Enter your password when prompted.
Complete Setup
The app will guide you through naming your doorbell, setting motion zones, and enabling notifications.
Step 10: Final Testing and Adjustments
Once setup is complete, test everything to ensure it works properly.
Test Live View
Open the app and tap “Live View” to see the camera feed. Check for clarity, angle, and lighting.
Test Motion Detection
Walk in front of the doorbell to trigger motion alerts. Adjust sensitivity in the app if needed.
Test the Doorbell Button
Press the button and confirm you receive a notification and see the live feed.
Adjust Settings
Customize settings like:
- Motion zones (to avoid false alerts from trees or cars)
- Notification preferences (push, email, etc.)
