What You’ll Need Before Starting

Before you begin the installation, gather all the necessary tools and materials. Having everything ready will save time and prevent frustration mid-process.

Tools and Materials Checklist

• Blink Video Doorbell (wired version)
• Smartphone with the Blink app installed (iOS or Android)
• Screwdriver (Phillips head, typically #2)
• Drill and drill bits (if mounting into brick, concrete, or hard surfaces)
• Level (to ensure the doorbell is straight)
• Voltage tester (optional but recommended)
• Wire strippers (if wires need trimming)
• Pencil or marker (for marking drill holes)
• Safety gloves and goggles (for protection)

Check Your Existing Doorbell System

Not all homes are ready for a wired smart doorbell. The Blink wired doorbell requires a working doorbell transformer and low-voltage wiring (typically 16–24 AWG). Here’s how to check:

• Locate your doorbell chime: It’s usually inside your front hallway or near the entrance.
• Find the transformer: It’s often in the basement, attic, or near your electrical panel. Look for a small black or gray box with wires leading to the chime.
• Check voltage: Use a multimeter or voltage tester to confirm the transformer outputs between 8–24 volts AC. Blink requires at least 8V to function properly.
• Inspect wiring: Make sure the wires from the transformer to the doorbell location are intact and not frayed.

If your transformer is below 8V or your wiring is damaged, you may need to upgrade the transformer or consult an electrician. Blink recommends a 16V transformer for optimal performance.

Step 1: Turn Off the Power

Safety comes first. Even though doorbell systems use low voltage, it’s still important to turn off the power to avoid accidental shocks or short circuits.

How to Safely Shut Off Power

• Go to your home’s main electrical panel (breaker box).
• Locate the circuit breaker labeled “doorbell,” “chime,” or “low voltage.” If it’s not labeled, turn off the main breaker to be safe.
• Use a non-contact voltage tester at the doorbell location to confirm no power is flowing.
• Place a note on the breaker box to warn others not to turn the power back on during installation.

Never skip this step. Even low-voltage systems can cause injury or damage your Blink doorbell if mishandled.

Step 2: Remove the Old Doorbell (If Applicable)

If you’re replacing an existing doorbell, you’ll need to remove it before installing the Blink model.

Removing the Existing Doorbell

• Unscrew the front plate of the old doorbell using a screwdriver.
• Gently pull the doorbell away from the wall to expose the wires.
• Take a photo of the wire connections for reference (optional but helpful).
• Loosen the terminal screws and disconnect the wires. Label them if needed (e.g., “Front” and “Trans” for transformer).
• Set the old doorbell aside.

Keep the wires accessible and avoid letting them fall back into the wall. You can use electrical tape to temporarily secure them to the wall.

Step 3: Prepare the Wires

The Blink wired doorbell connects directly to your home’s doorbell wiring. Proper preparation ensures a secure and reliable connection.

Stripping and Preparing the Wires

• If the wire ends are frayed or too short, use wire strippers to expose about 1/4 inch of copper.
• Twist the exposed copper strands to prevent fraying.
• Ensure both wires (front and transformer) are clean and free of corrosion.

If your wires are too short or damaged, you may need to extend them using wire nuts and additional low-voltage wire. This is a job best handled by a licensed electrician if you’re unsure.

Step 4: Install the Mounting Bracket

The Blink doorbell comes with a mounting bracket that secures the device to your wall. Proper installation ensures stability and correct alignment.

Choosing the Right Location

• Mount the doorbell at a height of 48 inches (4 feet) from the ground—this is the standard for most homes.
• Ensure it’s within Wi-Fi range (ideally within 30–50 feet of your router).
• Avoid direct sunlight or extreme weather exposure if possible.
• Make sure the location allows a clear view of your front door and walkway.

Mounting the Bracket

• Hold the mounting bracket against the wall where you want to install the doorbell.
• Use a level to ensure it’s straight.
• Mark the screw holes with a pencil.
• Drill pilot holes if mounting into brick, concrete, or hard siding.
• Secure the bracket with the provided screws using a screwdriver or drill.
• Ensure the bracket is tight and doesn’t wobble.

For angled mounting (e.g., on a corner or sloped wall), Blink offers an optional wedge kit (sold separately) to adjust the viewing angle.

Step 5: Connect the Wires to the Blink Doorbell

Now it’s time to connect your home’s doorbell wires to the Blink device. This step is crucial for power and functionality.

Understanding the Terminals

The Blink wired doorbell has two screw terminals labeled “Front” and “Trans”:

• Front: Connects to the wire that runs from the doorbell button to the chime.
• Trans: Connects to the wire from the transformer (power source).

It doesn’t matter which wire goes where—Blink’s design allows for either configuration. However, consistency helps with troubleshooting.

Connecting the Wires

• Loosen the terminal screws on the back of the Blink doorbell.
• Insert one wire into the “Front” terminal and the other into the “Trans” terminal.
• Tighten the screws securely to hold the wires in place.
• Give the wires a gentle tug to ensure they’re firmly connected.

Do not overtighten the screws, as this can damage the terminals. Also, avoid letting bare wire touch each other, which could cause a short.

Step 6: Attach the Blink Doorbell to the Bracket

With the wires connected, it’s time to mount the doorbell onto the bracket.

Securing the Device

• Align the back of the Blink doorbell with the mounting bracket.
• Slide the doorbell downward until it clicks into place.
• Ensure it’s seated properly and doesn’t wobble.
• If your model includes a security screw, insert it through the bottom of the doorbell and tighten it to prevent tampering.

The doorbell should now be securely attached and ready for power-up.

Step 7: Restore Power and Test the System

Now that everything is connected, it’s time to turn the power back on and test your new Blink doorbell.

Restoring Power

• Return to your electrical panel and turn the breaker back on.
• Wait 30–60 seconds for the system to power up.
• Listen for the doorbell chime (if connected) to confirm power is flowing.

Testing the Blink Doorbell

• Open the Blink app on your smartphone.
• The app should detect the new doorbell and prompt you to complete setup.
