Before you start, let’s make sure you have all the parts. Here’s what should be included in your Blink Video Doorbell + Sync Module 2 kit:
- Blink Video Doorbell (main unit)
- Sync Module 2 (small black box)
- Mounting bracket (angled and flat options)
- Screws and wall anchors
- Wire connectors (for existing doorbell wiring)
- Double-sided adhesive tape (optional mounting)
- Micro-USB cable (for Sync Module power)
- Quick start guide
Pro Tip: Keep the packaging until installation is complete. If something goes wrong, you’ll want to return or exchange the product in original condition.
Tools You’ll Need
You don’t need a full toolbox, but having these on hand will make the job easier:
- Screwdriver (Phillips head)
- Drill (optional, for mounting)
- Level (to keep the doorbell straight)
- Smartphone or tablet with the Blink app installed
- Wi-Fi network name and password
- Ladder (if installing high up)
If you’re replacing an existing doorbell, you might also need wire strippers or pliers to disconnect old wires.
Step 1: Download the Blink App
Before touching any hardware, download the Blink Home Monitor app. It’s available for free on the Apple App Store (iOS) and Google Play Store (Android).
Once installed, open the app and create a Blink account using your email address. You’ll need this account to manage your devices, view recordings, and receive alerts.
Why the app first? The app walks you through setup, helps you connect to Wi-Fi, and pairs your doorbell with the Sync Module. Skipping this step can lead to confusion later.
Step 2: Choose the Right Location
Where you install your doorbell matters—a lot. Here’s what to consider:
Wi-Fi Signal Strength
Your doorbell needs a strong Wi-Fi connection to stream video and send alerts. Use your phone to check signal strength at the installation spot. If it’s weak, consider moving your router or using a Wi-Fi extender.
Tip: The Blink app has a built-in signal checker during setup. Use it to confirm your location is good.
Height and Angle
Mount the doorbell about 48–52 inches above the ground. This height captures faces clearly and reduces tampering risk.
Use the angled mounting bracket if your doorbell faces a wall or needs to point outward. The flat bracket works for straight-on installations.
Power Source
The Blink doorbell is battery-powered, but it can also use existing doorbell wiring for trickle charging. If you have wiring, you can connect it for longer battery life. If not, the batteries will last 1–2 years with normal use.
Note: The Sync Module 2 must be plugged into a power outlet and connected to your Wi-Fi network. Place it indoors, near your router or in a central location.
Step 3: Install the Sync Module 2
The Sync Module 2 is the brain of your Blink system. It connects to your Wi-Fi, stores video clips, and communicates with your doorbell.
Find a Spot for the Sync Module
Choose an indoor location with:
- A power outlet (within 6 feet)
- Strong Wi-Fi signal
- Clear line of sight to your doorbell (ideally within 300 feet)
Avoid placing it behind thick walls, metal objects, or in basements with weak signals.
Plug It In
Connect the Micro-USB cable to the Sync Module and plug the other end into a power outlet. The LED light will turn solid green when powered.
Connect to Wi-Fi via the App
Open the Blink app and follow these steps:
- Tap “Add a System” or “+” to start setup.
- Select “Sync Module 2.”
- Scan the QR code on the back of the module using your phone’s camera.
- Enter your Wi-Fi network name and password.
- Wait for the app to connect. The LED will blink blue during setup, then turn solid green when connected.
Pro Tip: If the connection fails, move the Sync Module closer to your router and try again.
Step 4: Prepare the Doorbell Mounting Location
Now it’s time to prep your doorbell spot.
Turn Off Power (If Replacing Wired Doorbell)
If you’re replacing an existing doorbell, turn off power at the circuit breaker to avoid shocks. Use a voltage tester to confirm wires are dead.
Remove Old Doorbell (If Applicable)
Unscrew the old doorbell and disconnect the wires. Leave the wires exposed so you can connect them to the Blink doorbell later.
Clean the Surface
Wipe the mounting area with a dry cloth to remove dust or grease. This helps the adhesive tape or screws hold better.
Step 5: Mount the Doorbell
You have two mounting options: screws or adhesive tape.
Option 1: Screw Mounting (Recommended)
This is the most secure method, especially in windy or high-traffic areas.
- Hold the mounting bracket against the wall at your chosen height.
- Use a level to make sure it’s straight.
- Mark the screw holes with a pencil.
- Drill pilot holes (if needed) and insert wall anchors for brick or drywall.
- Screw the bracket into place.
- Attach the doorbell to the bracket by sliding it down until it clicks.
Tip: Use the angled bracket if you need to adjust the viewing angle.
Option 2: Adhesive Tape Mounting
Great for renters or smooth surfaces like glass or metal.
- Peel off the backing from the double-sided tape.
- Press the bracket firmly against the wall for 30 seconds.
- Wait 1 hour before attaching the doorbell to let the adhesive set.
- Slide the doorbell onto the bracket.
Warning: Adhesive may not hold in extreme temperatures or on rough surfaces.
Step 6: Connect Wiring (Optional)
If you have existing doorbell wires, you can connect them to extend battery life.
How to Connect Wires
- Strip about 1/4 inch of insulation from each wire.
- Loosen the terminal screws on the back of the doorbell.
- Insert the wires into the terminals (polarity doesn’t matter).
- Tighten the screws to secure the wires.
- Push the wires back into the wall and attach the doorbell to the bracket.
Note:> The doorbell will still work on batteries alone. Wiring just provides trickle charging.
Step 7: Insert Batteries
Even if you’re using wiring, you’ll need batteries to power the doorbell initially.
- Remove the doorbell from the bracket by sliding it up.
- Open the battery compartment on the back.
- Insert two AA lithium batteries (included).
- Close the compartment and reattach the doorbell.
Pro Tip: Use lithium batteries for longer life and better performance in cold weather.
Step 8: Pair the Doorbell with the Sync Module
Now it’s time to connect your doorbell to the Sync Module via the app.
Open the Blink App
- Tap “Add a Device” or “+” in the app.
- Select “Doorbell.”
- Scan the QR code on the back of the doorbell.
- The app will search for the doorbell. This may take 1–2 minutes.
- Once found, tap “Add” to pair it with your Sync Module.
Test the Connection
After pairing, the app will show the doorbell as “Online.” Tap the live view button to see the camera feed.
Troubleshooting Tip: If the doorbell doesn’t appear, move closer to the Sync Module and try again.
Step 9: Customize Your Settings
Now that everything’s connected, personalize your doorbell experience.
Motion Detection
Adjust sensitivity and set activity zones to avoid false alerts from passing cars or pets.
Notification Settings
Choose when to receive alerts: always, only at night, or during specific hours.
Video Quality
Select HD or standard resolution. HD uses more data but gives clearer images.
Two-Way Audio
Test the microphone and speaker by speaking through the app while near the doorbell.
Clip Length
Set how long recordings last (10, 30, or 60 seconds).
Step 10: Test Everything
Before calling it a day, run a full test.
- Press the doorbell button to see if it chimes and sends a notification.
- Walk in front of the doorbell to trigger motion detection.
- Check the live view and playback a recorded clip.
- Test two-way audio by talking and listening.
If everything works, you’re all set!
Troubleshooting Common Issues
Even with careful setup, problems can happen. Here’s how to fix the most common ones.
Doorbell Won’t Connect to Sync Module
