Before you begin attaching your Blink doorbell, gather these essential items:
- Blink Video Doorbell kit (includes doorbell unit, mounting plate, screws, anchors, drill bit, and screwdriver)
- Smartphone or tablet with the Blink app installed (available on iOS and Android)
- Wi-Fi network (2.4 GHz band required; 5 GHz is not supported)
- Stepladder (if mounting above shoulder height)
- Pencil for marking drill points
- Power drill (optional but recommended for masonry or brick)
- Voltage tester (if replacing a wired doorbell—highly recommended for safety)
Most Blink doorbells are battery-powered, so you won’t need to connect to existing wiring unless you choose the wired option. However, even battery models can be installed near old wires—just make sure they’re disconnected or capped off safely.
Pro tip: Charge your Blink doorbell batteries fully before installation. The device ships with partial charge, but a full charge ensures smooth setup and avoids mid-installation power loss.
Step 1: Choose the Perfect Mounting Location
The success of your Blink doorbell starts with where you place it. A poor location can lead to weak Wi-Fi signals, blind spots, or false motion alerts from passing cars or trees.
Ideal Height and Angle
Mount your Blink doorbell between 48 and 60 inches from the ground. This height captures most visitors’ faces clearly while staying out of easy reach for tampering.
Angle the doorbell slightly toward the walkway or driveway—not straight ahead. A 15–30 degree downward tilt helps focus on people approaching your door and reduces glare from sunlight or porch lights.
Wi-Fi Signal Strength Matters
Your Blink doorbell needs a strong 2.4 GHz Wi-Fi signal to stream video and send alerts. Use your phone to check signal strength at the intended spot. If it’s weak, consider:
- Moving your router closer
- Installing a Wi-Fi extender
- Using a mesh network system
Avoid placing the doorbell behind metal doors, thick walls, or large obstructions like trees or fences—these can block signals.
Consider Lighting and Weather
Choose a spot protected from direct rain, snow, and harsh sunlight. Overhangs or eaves work well. Avoid areas with constant shadows or backlighting (e.g., facing directly into the sun), as this can wash out video quality.
If your porch is very dark at night, consider adding a motion-activated light nearby. Blink doorbells have infrared night vision, but extra lighting improves color accuracy.
Step 2: Turn Off Power (If Replacing a Wired Doorbell)
Even if you’re installing a battery-powered Blink doorbell, it’s smart to turn off power if you’re working near existing doorbell wiring. Electricity and DIY don’t mix—safety first!
Locate Your Circuit Breaker
Go to your home’s electrical panel and find the breaker labeled “Doorbell,” “Chime,” or something similar. If there’s no label, turn off the main breaker to be safe.
Test the Wires
Use a non-contact voltage tester to confirm power is off. Touch the tester near the existing doorbell wires. If it beeps or lights up, power is still on—double-check your breaker.
Once confirmed safe, unscrew the old doorbell and disconnect the wires. Cap them with wire nuts or electrical tape to prevent accidental contact.
Note: If you’re using the Blink doorbell in wired mode (requires compatible transformer), you’ll reconnect these wires later. But for battery-only setups, leave them capped and tucked into the wall.
Step 3: Install the Mounting Plate
The mounting plate is the backbone of your installation. It holds the doorbell securely and allows for easy removal when replacing batteries.
Mark Drill Points
Hold the mounting plate against the wall where you want to install the doorbell. Use a pencil to mark the two screw holes. Make sure the plate is level—use a spirit level or the leveling tool in your phone’s compass app.
Drill Pilot Holes
If mounting into wood or drywall, use the included drill bit to create pilot holes at the marked spots. This prevents splitting and makes screwing easier.
For brick, concrete, or stucco, use a masonry drill bit (not included) and wall anchors. Tap the anchors gently into the holes with a hammer.
Secure the Plate
Line up the mounting plate with the holes and insert the screws. Tighten them firmly but don’t over-tighten—this can crack the plastic or strip the screw holes.
Ensure the plate is flush against the wall with no gaps. A wobbly plate will cause the doorbell to shift, affecting video angle and motion detection.
Step 4: Attach the Blink Doorbell
Now it’s time to connect the actual device.
Insert Batteries (For Battery Models)
Slide open the battery compartment on the back of the doorbell. Insert two AA lithium batteries (recommended for longer life) with the correct polarity (+ and –). Close the compartment securely.
Lithium batteries perform better in cold weather and last up to twice as long as alkaline ones—worth the small extra cost.
Snap the Doorbell onto the Plate
Align the grooves on the back of the doorbell with the tabs on the mounting plate. Push firmly until you hear a click. Give it a gentle tug to confirm it’s locked in place.
If you’re using the wired version, connect the two wires from your wall to the terminals on the back of the doorbell before snapping it on. Match wire colors if possible (though polarity doesn’t matter for Blink).
Secure with Anti-Theft Screw (Optional but Recommended)
Use the small security screw provided to lock the faceplate. This prevents thieves from easily removing your doorbell. You’ll need the included Allen key to tighten it.
While not required, this small step adds significant security—especially in high-traffic areas.
Step 5: Set Up the Blink App
Your doorbell isn’t fully functional until it’s connected to the Blink app. This free app controls everything—from live view to motion zones.
Download and Open the App
Search “Blink Home Monitor” in the App Store (iOS) or Google Play (Android). Download and install it.
Create or Log In to Your Account
If you’re new to Blink, tap “Create Account” and follow the prompts. You’ll need an email address and password. Existing users can log in directly.
Add Your Doorbell
Tap the “+” icon and select “Add Device.” Choose “Doorbell” from the list. The app will guide you through scanning the QR code on the back of your doorbell or entering the serial number manually.
Connect to Wi-Fi
Select your home Wi-Fi network and enter the password. Make sure you’re on a 2.4 GHz network—Blink doesn’t support 5 GHz. The app will send the network info to your doorbell.
Wait for the confirmation message. This may take 1–2 minutes. If it fails, move closer to your router or restart the doorbell by removing and reinserting the batteries.
Name Your Doorbell
Give your doorbell a name like “Front Door” or “Porch.” This helps if you have multiple Blink devices.
Step 6: Configure Settings and Test
With the hardware installed and app connected, it’s time to fine-tune your setup.
Adjust Motion Zones
In the app, go to your doorbell settings and tap “Motion Zones.” Draw boxes around areas where you want to detect motion (e.g., walkway) and exclude areas like busy streets or swaying trees.
This reduces false alerts and saves battery life.
Set Alert Preferences
Choose how you want to be notified: push notifications, email, or both. You can also set quiet hours to avoid midnight disturbances.
Test Live View and Motion
Tap “Live View” in the app to see real-time video. Walk in front of the doorbell to trigger motion. Check that you receive an alert and that the video quality is clear.
If the video is blurry or delayed, check your Wi-Fi signal or move the doorbell slightly.
Check Night Vision
Test the doorbell at night or in low light. The infrared LEDs should activate automatically, providing a clear black-and-white image.
Troubleshooting Common Installation Issues
Even with careful planning, problems can arise. Here’s how to fix the most common ones.
