Before we dive into installation, let’s talk about why Blink is a great choice. Blink doorbells are affordable, easy to install, and work seamlessly with the Blink Home Monitor app. They offer HD video, night vision, motion detection, and two-way talk—all without monthly fees for basic features.

Unlike some competitors, Blink doorbells can work with or without existing wiring. But if you do have a wired doorbell, connecting it properly ensures reliable power and better performance. That’s why learning how to connect Blink doorbell to doorbell is so important.

What You’ll Need

Before you begin, gather these tools and materials:

  • Blink Video Doorbell (wired model)
  • Existing doorbell chime and wiring
  • Screwdriver (Phillips and flathead)
  • Voltage tester (non-contact type recommended)
  • Wire strippers
  • Electrical tape
  • Smartphone with Blink app installed
  • Wi-Fi network (2.4 GHz only—Blink doesn’t support 5 GHz)

Optional but helpful:

  • Drill and wall anchors (if mounting on brick or concrete)
  • Level tool
  • Helper (for holding the doorbell during installation)

Step 1: Check Compatibility

Not all doorbell systems are compatible with Blink. Before you start, you need to verify that your existing setup can support the Blink doorbell.

Check Your Doorbell Voltage

Most wired doorbells run on low voltage (8–24 volts AC). Blink doorbells are designed to work within this range. To check:

  1. Turn off power at the breaker.
  2. Remove your existing doorbell button.
  3. Use a voltage tester to measure the voltage across the two wires.

If the voltage is between 8V and 24V AC, you’re good to go. If it’s higher, you may need a transformer. If it’s lower or there’s no power, your wiring may be damaged or disconnected.

Inspect the Wiring

Look at the wires behind your old doorbell. Are they intact? Are the ends clean and not frayed? If the wires are brittle, corroded, or too short, you may need to replace them or extend them with wire nuts.

Also, check that your doorbell chime is mechanical (not digital). Blink works best with traditional chimes. Some digital chimes may not trigger properly or could cause interference.

Confirm Wi-Fi Signal Strength

Blink doorbells rely on Wi-Fi for video streaming and alerts. Use your phone to check the signal strength at your door. If it’s weak, consider installing a Wi-Fi extender or mesh system.

Step 2: Turn Off Power

Safety first! Working with electricity is dangerous if you’re not careful.

Locate Your Breaker Box

Find the circuit breaker that controls your doorbell. It’s often labeled “doorbell,” “chime,” or “front door.” If you’re unsure, turn off the main breaker to be safe.

Test the Power

Even after turning off the breaker, use your voltage tester to confirm there’s no power at the doorbell wires. Touch the tester to each wire—if it beeps or lights up, the power is still on. Double-check your breaker.

Label the Wires

Before disconnecting anything, take a photo or label the wires (e.g., “Front Door,” “Transformer”). This helps you reconnect them correctly later.

Step 3: Remove the Old Doorbell

Now it’s time to take off your existing doorbell button.

Unscrew the Faceplate

Use a screwdriver to remove the screws holding the old doorbell in place. Gently pull the button away from the wall.

Disconnect the Wires

Loosen the terminal screws and carefully remove the wires. Don’t let them fall back into the wall. You can tape them to the wall or hold them with a helper.

Inspect the Mounting Area

Check for damage, moisture, or mold. If the wall is uneven, you may need to use spacers or shims when installing the Blink doorbell.

Step 4: Prepare the Wires

Blink doorbells need clean, exposed wire ends to make a solid connection.

Strip the Wire Ends

Use wire strippers to remove about 1/4 inch of insulation from each wire. Be careful not to cut the copper strands.

Twist the Strands

Gently twist the exposed copper to keep the strands together. This prevents fraying and ensures a tight connection.

Check Wire Length

The wires should be long enough to reach the Blink doorbell terminals with a little slack. If they’re too short, you may need to extend them using wire nuts and additional low-voltage wire.

Step 5: Install the Blink Doorbell

Now for the fun part—mounting your new Blink doorbell.

Attach the Mounting Plate

Hold the Blink mounting plate against the wall where you want the doorbell. Use a level to make sure it’s straight. Mark the screw holes with a pencil.

If you’re drilling into brick or concrete, use a masonry bit and wall anchors. For wood or drywall, standard screws will work.

Secure the Plate

Screw the mounting plate into place. Make sure it’s tight and doesn’t wobble.

Connect the Wires

Blink doorbells have two terminals: “Front” and “Trans.” It doesn’t matter which wire goes where—Blink is non-polarized. Simply insert each wire into the terminal and tighten the screw.

Double-check that the wires are secure and not touching each other.

Attach the Doorbell

Slide the Blink doorbell onto the mounting plate until it clicks into place. Give it a gentle tug to make sure it’s locked.

Step 6: Restore Power and Test

You’re almost done! Now it’s time to turn the power back on and test your setup.

Turn On the Breaker

Go back to your breaker box and turn the doorbell circuit back on.

Check for Power

Use your voltage tester again to confirm power is flowing. You should see voltage at the doorbell terminals.

Test the Chime

Press the doorbell button. Your existing chime should ring. If it doesn’t, double-check your wiring and connections.

Step 7: Set Up the Blink App

The Blink app is your control center for the doorbell. It’s where you’ll sync the device, adjust settings, and view live video.

Download the App

If you haven’t already, download the Blink Home Monitor app from the Apple App Store or Google Play.

Create or Log In to Your Account

Open the app and sign in with your Blink account. If you don’t have one, create a new account using your email.

Add a New Device

Tap the “+” icon and select “Add Device.” Choose “Doorbell” from the list.

Scan the QR Code

The app will ask you to scan the QR code on the back of your Blink doorbell. Use your phone’s camera to scan it.

Connect to Wi-Fi

Enter your Wi-Fi network name (SSID) and password. Remember, Blink only works on 2.4 GHz networks. If your router broadcasts both 2.4 GHz and 5 GHz, make sure you’re connecting to the 2.4 GHz band.

Name Your Doorbell

Give your doorbell a name, like “Front Door” or “Porch.” This helps if you have multiple Blink devices.

Complete Setup

Follow the on-screen prompts to finish setup. The app will test the connection and confirm everything is working.

Step 8: Test All Features

Now that everything is connected, it’s time to test the full functionality.

Test Video and Audio

Open the app and tap “Live View” to see the camera feed. Speak into your phone—you should hear audio from the doorbell. Tap the talk button to speak through the doorbell.

Test Motion Detection

Walk in front of the doorbell to trigger motion alerts. You should receive a notification on your phone within a few seconds.

Test the Doorbell Button

Press the doorbell button. The chime should ring, and you should get a notification with a video clip.

Check Night Vision

Turn off the lights and test the camera in the dark. The infrared LEDs should activate, providing clear black-and-white video.

Troubleshooting Common Issues

Even with careful installation, problems can happen. Here’s how to fix the most common issues.

Doorbell Doesn’t Ring

If your chime doesn’t ring when you press the button:

  • Check that power is on at the breaker.
  • Verify the wires are connected securely.
  • Test the voltage—low voltage can prevent the chime from working.
