Check Your Existing Doorbell System
The Blink Video Doorbell Wired is designed to work with most existing wired doorbell systems, but not all. Before you begin, confirm your setup is compatible.
Most homes have a low-voltage doorbell system powered by a transformer (usually located near your furnace, breaker panel, or attic). This transformer steps down your home’s 120V power to 8–24V AC—perfect for doorbells.
To check compatibility:
- Locate your doorbell transformer. It’s often a small black box with wires running to your doorbell.
- Use a multimeter or voltage tester to measure the voltage across the doorbell wires at the chime or button.
- You need at least 8V AC and 10VA (volt-amperes) for the Blink doorbell to work reliably.
If your system is below 8V, the doorbell may not power on or may behave erratically. In that case, you may need to upgrade your transformer—something we’ll touch on later.
Step 1: Turn Off the Power
Safety first! Working with electricity—even low voltage—can be dangerous if you’re not careful.
Shut Off the Breaker
- Go to your home’s main electrical panel (breaker box).
- Locate the breaker that controls your doorbell circuit. It may be labeled “doorbell,” “chime,” or “front door.” If not, turn off the main breaker to be safe.
- Use a non-contact voltage tester at the doorbell button to confirm power is off. Touch the tester to the wire terminals—if it doesn’t beep or light up, you’re good to go.
Pro Tip: Place a piece of tape over the breaker switch with “DO NOT TURN ON” written on it. This prevents someone from accidentally restoring power while you’re working.
Step 2: Remove the Old Doorbell
If you’re replacing an existing doorbell, you’ll need to remove it first.
Unscrew and Disconnect
- Use a screwdriver to remove the screws holding the old doorbell button to the wall.
- Gently pull the button away from the wall to expose the wires.
- Take a photo of the wiring setup for reference—this helps if you need to troubleshoot later.
- Loosen the terminal screws and disconnect the two wires. Don’t let them touch each other or the wall.
Cap the Wires
To prevent short circuits, twist wire nuts onto the exposed ends of the wires, or wrap them tightly with electrical tape. This keeps them safe and insulated while you work.
Step 3: Prepare the Wires
The Blink doorbell uses the same two wires as your old doorbell—no extra wiring needed.
Strip the Wire Ends
- Use wire strippers to remove about 1/4 inch (6 mm) of insulation from each wire end.
- Twist the exposed copper strands to keep them neat and prevent fraying.
Note: If your wires are too short or damaged, you may need to extend them with additional low-voltage wire and wire nuts. Make sure connections are secure and insulated.
Step 4: Install the Mounting Plate
The mounting plate holds the Blink doorbell securely and provides a clean finish.
Position the Plate
- Hold the mounting plate against the wall where you want the doorbell.
- Use a level to ensure it’s straight—crooked doorbells look unprofessional and can affect video angle.
- Mark the screw holes with a pencil.
Drill and Secure
- Drill pilot holes into the wall at the marked spots. Use wall anchors if you’re drilling into drywall, brick, or concrete.
- Align the plate with the holes and screw it into place using the provided screws.
- Make sure the plate is tight and doesn’t wobble.
Pro Tip: If your doorbell is on a corner or uneven surface, use the included wedge accessory to adjust the angle for a better view of visitors.
Step 5: Connect the Wires
Now it’s time to connect the wires to the Blink doorbell.
Attach Wires to the Doorbell
- Take the two wires from the wall and insert them into the back of the Blink doorbell unit.
- The Blink doorbell is polarity-insensitive, meaning you don’t need to worry about positive and negative—just connect one wire to each terminal.
- Push the wires firmly into the slots until they click or feel secure.
Important: Do not strip more than 1/4 inch of wire. Too much exposed copper can cause short circuits.
Secure the Doorbell to the Plate
- Align the doorbell with the mounting plate.
- Slide it down until it locks into place with a click.
- Gently tug to confirm it’s secure.
Step 6: Restore Power and Test
With everything connected, it’s time to turn the power back on and see if it works.
Turn On the Breaker
- Return to the breaker panel and flip the doorbell breaker back on.
- Wait about 30 seconds for the system to power up.
Check for Power
Look at the Blink doorbell. You should see a small light on the front—usually a blinking blue or solid white light. This indicates the device is receiving power and initializing.
If the light doesn’t appear:
- Double-check that the breaker is on.
- Use the voltage tester to confirm power at the wires.
- Recheck wire connections—make sure they’re fully inserted and not loose.
Step 7: Set Up the Blink App
The Blink app is your control center for the doorbell. It handles Wi-Fi setup, notifications, and live viewing.
Download and Open the App
- Download the Blink Home Monitor app from the Apple App Store or Google Play.
- Create an account or log in if you already have one.
Add Your Doorbell
- Tap the “+” icon and select “Add Device.”
- Choose “Video Doorbell” and then “Wired.”
- Follow the on-screen prompts.
- When prompted, scan the QR code on the back of your Blink doorbell using your phone’s camera.
Connect to Wi-Fi
- Select your home Wi-Fi network (must be 2.4 GHz—5 GHz is not supported).
- Enter your Wi-Fi password.
- Wait while the app connects the doorbell to your network. This may take 1–2 minutes.
Pro Tip: Stand close to your router during setup to ensure a strong signal. Weak Wi-Fi can cause connection failures.
Complete Setup
Once connected, the app will guide you through:
- Setting motion zones (areas you want to monitor)
- Adjusting motion sensitivity
- Enabling notifications
- Testing the doorbell button
Step 8: Test the Doorbell
Now that everything is set up, it’s time to test.
Press the Button
Press the doorbell button. You should:
- Hear a chime (if your indoor chime is connected)
- Receive a notification on your phone
- See a live video feed in the app
Check Video Quality
Open the app and view the live feed. Make sure:
- The image is clear and not blurry
- The angle captures visitors from head to toe
- Night vision works in low light
If the video is dark or grainy, adjust the doorbell angle or clean the lens with a soft cloth.
Troubleshooting Common Issues
Even with careful installation, problems can happen. Here’s how to fix the most common ones.
Doorbell Won’t Power On
- Check the breaker: Ensure power is restored.
- Test voltage: Use a multimeter to confirm 8–24V AC at the wires.
