Before you begin, gather these tools and materials to ensure a smooth installation:
- Blink Video Doorbell (wired model)
- Smartphone with the Blink Home Monitor app installed
- Screwdriver (usually Phillips head)
- Wire strippers (if wires need trimming)
- Voltage tester (optional but recommended)
- Electrical tape
- Wire nuts (usually included with Blink kit)
- Ladder (if your doorbell is high up)
- Gloves and safety glasses (for protection)
Most of these items are common household tools. The Blink kit includes the doorbell, mounting bracket, screws, anchors, and wire nuts. Make sure your smartphone is charged and connected to Wi-Fi before starting.
Step 1: Turn Off the Power
Safety is the most important part of any electrical project. Before touching any wires, you must turn off the power to your doorbell circuit.
Locate Your Circuit Breaker
Go to your home’s electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “Doorbell,” “Front Door,” or something similar. If it’s not labeled, you may need to test breakers one by one.
Turn Off the Correct Breaker
Switch the breaker to the “OFF” position. To confirm the power is off, ring your existing doorbell. If it doesn’t chime, the power is successfully disconnected.
Pro Tip: Use a non-contact voltage tester near the doorbell wires to double-check. If the tester beeps or lights up, the power is still on—double-check your breaker.
Leave a Note
Place a note on the breaker panel saying “Do not turn on—working on doorbell.” This prevents someone else from accidentally restoring power while you’re working.
Step 2: Remove Your Existing Doorbell
Now that the power is off, it’s time to remove your old doorbell.
Unscrew the Old Doorbell
Use a screwdriver to remove the screws holding your current doorbell to the wall. Gently pull the doorbell away from the wall to expose the wires.
Label the Wires (Optional but Helpful)
You’ll see two wires connected to the back of the doorbell. These are typically labeled “Front” and “Trans” (transformer), but they may not be marked. If you’re unsure, take a photo or label them with tape (e.g., “Wire A” and “Wire B”) so you can reconnect them correctly later.
Disconnect the Wires
Loosen the terminal screws or release the wire connectors to free the wires. Be careful not to let the wires slip back into the wall. If they do, you may need a fish tape or needle-nose pliers to pull them out.
Pro Tip: Bend the wire ends slightly so they stay exposed and easy to handle.
Step 3: Check Voltage Compatibility
Blink Doorbell is designed to work with standard wired doorbell systems, but it’s important to verify compatibility.
Check Your Doorbell Transformer
The transformer converts household voltage (120V) to low voltage (usually 8–24V AC) for the doorbell. Most homes have transformers that output 16V or 24V, which work perfectly with Blink.
To check:
- Look for a small box near your doorbell, chime, or furnace.
- It may be labeled with voltage (e.g., “16V AC”).
- If you can’t find it, assume it’s compatible unless your doorbell is very old.
Use a Multimeter (Optional)
If you have a multimeter, set it to AC voltage and touch the probes to the two doorbell wires. A reading between 8V and 24V AC means your system is compatible.
Warning: If your voltage is below 8V or above 24V, do not proceed. Contact an electrician or consider a wireless Blink model instead.
Step 4: Install the Blink Mounting Bracket
The mounting bracket ensures your Blink Doorbell is secure and properly aligned.
Position the Bracket
Hold the Blink mounting bracket against the wall where your old doorbell was. Make sure it’s level using a spirit level or the level tool in your smartphone.
Mark Screw Holes
Use a pencil to mark where the screws will go. If you’re drilling into brick, stucco, or concrete, use a masonry bit and wall anchors.
Drill and Secure
Drill pilot holes, then screw the bracket into place using the provided screws. Ensure it’s tight and doesn’t wobble.
Pro Tip: If your wall is uneven, use the included spacer to create a flush fit.
Step 5: Connect the Wires to Blink Doorbell
Now it’s time to connect your existing doorbell wires to the Blink Doorbell.
Prepare the Wires
If the wire ends are frayed or too short, use wire strippers to expose about 1/4 inch of copper. Twist the ends gently to keep them neat.
Attach Wires to the Bracket
The Blink mounting bracket has two terminal screws. Connect one wire to each screw—it doesn’t matter which wire goes where, as polarity isn’t an issue for doorbells.
Tighten the screws securely, but don’t over-tighten, as this can damage the wires.
Secure with Wire Nuts (Optional)
For extra safety, you can twist the wires together and cover them with a wire nut, then tape it with electrical tape. This prevents accidental contact.
Step 6: Attach the Blink Doorbell
With the wires connected, it’s time to mount the doorbell.
Align the Doorbell
Slide the Blink Doorbell onto the mounting bracket. You’ll hear a click when it’s securely in place.
Secure with Screw (If Applicable)
Some models include a security screw to prevent theft. Use the provided Allen key to tighten it at the bottom of the doorbell.
Check Alignment
Make sure the doorbell is level and facing forward. Adjust if needed before final tightening.
Step 7: Restore Power and Test
Now that everything is connected, it’s time to turn the power back on.
Turn On the Breaker
Return to your electrical panel and switch the doorbell breaker back to “ON.”
Wait for the Doorbell to Power Up
The Blink Doorbell will light up and begin initializing. This may take 30–60 seconds.
Test the Chime
Press the doorbell button. You should hear a chime from your existing doorbell chime inside the house. If not, check your wiring or chime settings in the app.
Pro Tip: If the chime doesn’t work, your chime may not be compatible with smart doorbells. You can disable the chime in the app and use the Blink chime accessory instead.
Step 8: Set Up the Blink App
The Blink app is essential for customizing your doorbell and receiving alerts.
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 Your Doorbell
Tap the “+” icon and select “Add Device.” Choose “Doorbell” and follow the on-screen instructions.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the Blink Doorbell. This pairs the device with your account.
Connect to Wi-Fi
Select your home Wi-Fi network and enter the password. The doorbell will connect and download any necessary updates.
Name Your Doorbell
Give your doorbell a name (e.g., “Front Door”) for easy identification.
Step 9: Customize Settings
Once connected, you can personalize your Blink Doorbell to suit your needs.
Adjust Motion Sensitivity
In the app, go to “Device Settings” > “Motion Settings.” Choose from Low, Medium, or High sensitivity. High sensitivity detects smaller movements but may increase false alerts.
Set Activity Zones
Draw zones on the camera view to focus on specific areas (e.g., your porch, not the street). This reduces unnecessary alerts.
Enable Two-Way Audio
Make sure two-way talk is turned on so you can speak to visitors through the app.
Choose Notification Preferences
Decide when you want to receive alerts—immediately, during certain hours, or only for people (if using person detection).
Set Up Chime (Optional)
If you have a Blink Chime, pair it in the app to hear alerts even if your existing chime doesn’t work.
Step 10: Final Testing and Tips
Before you call the job done, run a few final tests.
Test Live View
Open the app and tap “Live View” to see the camera feed. Check for clarity, lighting, and field of view.
Test Motion Detection
Walk in front of the doorbell to trigger motion. You should receive a notification and a recorded clip.
Test Two-Way Talk
Press the talk button in the app and speak. Ask someone to listen at the doorbell to confirm audio works both ways.
Check Night Vision
Test the doorbell at night or in low light. The infrared LEDs should provide clear black-and-white video.
Pro Tip: Clean the lens regularly with a soft, dry cloth to maintain video quality.
Troubleshooting Common Issues
Even with careful installation, you might run into a few hiccups. Here’s how to fix them.
Doorbell Doesn’t Power On
- Double-check that the breaker is on.
- Ensure wires are securely connected.
- Test voltage with a multimeter.
- Try reseating the doorbell on the bracket.
