Before you touch a single wire, gather these tools and materials. Having everything ready will save time and prevent frustration.

Tools and Materials Checklist

  • Blink doorbell wired unit (includes mounting plate and screws)
  • Smartphone with the Blink app installed (iOS or Android)
  • Screwdriver (Phillips head)
  • Voltage tester (non-contact type recommended)
  • Wire strippers (if wires need trimming)
  • Electrical tape (optional, for securing connections)
  • Ladder (if your doorbell is high up)
  • Gloves and safety glasses (for protection)

Check Your Existing Doorbell System

Not all homes are ready for a wired smart doorbell. Blink requires a working doorbell transformer that supplies 16–24 volts AC. Here’s how to check:

Step 1: Locate your existing doorbell chime inside the house. It’s usually near the front door or in a hallway.

Step 2: Remove the cover of the chime to expose the wiring. You’ll typically see two or three wires connected.

Step 3: Use a voltage tester to check the voltage across the two main terminals (usually labeled “Front” and “Trans”). If it reads between 16 and 24 volts AC, you’re good to go. If it’s below 16V, your transformer may be too weak, and you’ll need to upgrade it.

Pro Tip: If you’re unsure about your transformer, consult an electrician. Using a doorbell with insufficient power can damage the device or cause it to malfunction.

Step 1: Turn Off the Power

Safety first! Working with electricity is no joke. Even though doorbell wires carry low voltage, they can still give you a shock or damage your Blink doorbell if mishandled.

How to Safely Shut Off Power

  • Go to your home’s main electrical panel (breaker box).
  • Look for the circuit labeled “Doorbell,” “Chime,” or something similar. If you can’t find it, turn off the main breaker to be safe.
  • Use your voltage tester again at the doorbell wires to confirm there’s no power flowing.
  • Place a piece of tape over the breaker switch with a note like “Do not turn on – installing doorbell.”

Important: Never assume the power is off just because the old doorbell isn’t ringing. Always test with a voltage tester.

Step 2: Remove the Old Doorbell

Now that the power is off, it’s time to remove your existing doorbell.

Unscrew and Disconnect

  • Use your screwdriver to remove the screws holding the old doorbell to the wall.
  • Gently pull the doorbell away from the wall to expose the two wires underneath.
  • Take a photo of the wiring setup for reference—this helps if you need to reconnect the old one later.
  • Loosen the terminal screws on the back of the old doorbell and disconnect the wires.
  • Wrap the exposed ends of the wires with electrical tape to prevent them from touching each other or the wall.

Tip: If the wires are too short or damaged, use wire strippers to trim the ends and expose fresh copper. You’ll need about 1/2 inch of bare wire for a secure connection.

Step 3: Install the Blink Mounting Plate

The Blink doorbell comes with a mounting plate that attaches to your wall and holds the doorbell in place.

Position the Plate

  • Hold the mounting plate against the wall where you want the doorbell.
  • Make sure it’s level using a spirit level or the leveling tool in your smartphone.
  • Mark the screw holes with a pencil.
  • If you’re mounting on brick or concrete, use a drill to create pilot holes and insert wall anchors.

Secure the Plate

  • Align the plate with the marks and screw it into place using the provided screws.
  • Don’t overtighten—this can crack the plate or damage the wall.
  • Ensure the plate is snug and doesn’t wobble.

Pro Tip: If your doorbell is exposed to rain or direct sunlight, consider installing a weatherproof cover or awning to protect it.

Step 4: Connect the Wires to the Blink Doorbell

Now for the crucial part—connecting the wires. The Blink doorbell has two terminals: one for the front door wire and one for the transformer wire.

Identify the Wires

Most doorbells have two wires:

  • Front wire: Connects to the “Front” terminal on the chime.
  • Transformer wire: Connects to the “Trans” or “Common” terminal.

If you have a third wire (for a second doorbell or rear door), you can usually ignore it unless you’re setting up multiple buttons.

Attach the Wires

  • Remove the tape from the wire ends.
  • Loosen the terminal screws on the back of the Blink doorbell mounting plate.
  • Insert one wire into each terminal. It doesn’t matter which wire goes where—Blink is non-polarized.
  • Tighten the screws securely to hold the wires in place.
  • Gently tug on the wires to ensure they’re firmly connected.

Warning: Do not let the bare wire ends touch each other or the metal mounting plate. This can cause a short circuit.

Step 5: Attach the Blink Doorbell to the Mounting Plate

With the wires connected, it’s time to snap the doorbell onto the plate.

Snap It Into Place

  • Align the doorbell with the mounting plate.
  • Gently press it onto the plate until you hear a click.
  • The doorbell should sit flush against the wall with no gaps.

Secure with Security Screw (Optional)

  • Use the small security screw provided to lock the doorbell in place.
  • This prevents theft or accidental removal.
  • Store the screwdriver in a safe place—you’ll need it to remove the doorbell later.

Note: If you skip the security screw, the doorbell can be removed by hand, which may be useful for maintenance but increases theft risk.

Step 6: Turn the Power Back On

Now that everything is connected, restore power to test the installation.

Restore Power Safely

  • Go back to the breaker box and turn the doorbell circuit back on.
  • Wait about 30 seconds for the system to power up.
  • Listen for a chime or look for lights on the doorbell.

If the doorbell lights up or you hear a beep, that’s a good sign! If nothing happens, don’t panic—we’ll troubleshoot that in a moment.

Step 7: Set Up the Blink Doorbell in the App

The final step is syncing your doorbell with the Blink app. This is where the magic happens—connecting to Wi-Fi, setting up alerts, and customizing settings.

Download and Open the Blink App

  • If you haven’t already, download the Blink Home Monitor app from the App Store or Google Play.
  • Create an account or log in if you already have one.
  • Tap “Add Device” and select “Doorbell.”

Scan the QR Code

  • Hold your phone up to the QR code on the back of the doorbell or inside the app.
  • The app will detect the device and begin the setup process.

Connect to Wi-Fi

  • Select your home Wi-Fi network from the list.
  • Enter your Wi-Fi password when prompted.
  • Wait for the doorbell to connect—this may take a minute or two.

Tip: For best performance, place your doorbell within 30–50 feet of your Wi-Fi router. If your signal is weak, consider using a Wi-Fi extender.

Name Your Doorbell and Set Preferences

  • Give your doorbell a name (e.g., “Front Door” or “Main Entrance”).
  • Choose your time zone and enable motion detection.
  • Set up notification preferences—decide when and how you want to be alerted.
  • Enable two-way audio if desired.

Test the Doorbell

  • Press the doorbell button to trigger a notification on your phone.
  • Check that you receive an alert and can view the live video feed.
  • Test two-way audio by speaking through the app.
  • Walk in front of the doorbell to test motion detection.
