Blink Sync Module (2nd Gen recommended)
The Sync Module acts as a bridge between your doorbell and your home Wi-Fi network. Without it, your doorbell can’t send alerts or stream video.
Smartphone or Tablet
You’ll need a device with the Blink app installed. The app is available for both iOS and Android.
Wi-Fi Network
Your Sync Module connects to your 2.4 GHz Wi-Fi network. Note: Blink devices do not support 5 GHz networks.
Power Source for the Doorbell
Your doorbell can run on batteries (included) or be hardwired to existing doorbell wiring. Fresh batteries are recommended for first-time setup.
Screwdriver and Drill (if mounting)
You’ll need basic tools to mount the doorbell and Sync Module if you’re installing them permanently.
Stable Internet Connection
A strong Wi-Fi signal is crucial. Weak signals can cause pairing failures or poor video quality.
Step 1: Install the Blink App
The Blink app is your control center. It’s where you’ll add devices, view live feeds, and adjust settings.
Download the App
Go to the App Store (iOS) or Google Play Store (Android) and search for “Blink Home Monitor.” Download and install the official app.
Create or Log In to Your Account
If you’re new to Blink, tap “Create Account” and follow the prompts. Use a valid email and strong password. If you already have an account, just log in.
Verify Your Email
Check your inbox for a verification email from Blink. Click the link to confirm your account. This step is required before you can add devices.
Enable Notifications
Allow the app to send notifications so you’ll get alerts when someone rings the doorbell or motion is detected.
Step 2: Power Up Your Sync Module
The Sync Module needs power to work. It doesn’t run on batteries—it must be plugged in.
Find a Nearby Outlet
Place the Sync Module within 100 feet of your doorbell location. It should also be close to your Wi-Fi router for the best signal.
Plug It In
Connect the Sync Module to a power outlet using the included USB cable and power adapter. The module will light up when powered.
Check the LED Light
A solid blue light means the Sync Module is powered and ready. A blinking blue light means it’s searching for a network. If it’s red, there’s an issue—check power and Wi-Fi.
Wait for Initial Setup
Give the Sync Module 1–2 minutes to boot up and connect to your network. Don’t unplug it during this time.
Step 3: Add the Sync Module to the Blink App
Now it’s time to link your Sync Module to your Blink account.
Open the Blink App
Launch the app and tap the “+” (plus) icon in the top right corner.
Select “Add a System”
Choose “Add a System” from the menu. This will start the setup process for your Sync Module.
Scan the QR Code
Hold your phone over the QR code on the back of the Sync Module. The app will scan it automatically. If scanning fails, you can enter the serial number manually.
Connect to Wi-Fi
The app will prompt you to select your Wi-Fi network and enter the password. Make sure you’re connecting to a 2.4 GHz network. If your router broadcasts both 2.4 GHz and 5 GHz under the same name, temporarily rename the 5 GHz network to avoid confusion.
Wait for Confirmation
The app will show a progress bar as it connects the Sync Module to your network. This may take 1–3 minutes. Once done, you’ll see a success message.
Name Your System
Give your Sync Module a name, like “Front Door System” or “Home Security.” This helps if you have multiple systems.
Step 4: Prepare Your Blink Doorbell
Before pairing, make sure your doorbell is ready to communicate with the Sync Module.
Insert Batteries
If using batteries, open the doorbell cover and insert the four AA lithium batteries (included). Use lithium for longer life and better performance in cold weather.
Or Connect to Wiring (Optional)
If you have existing doorbell wiring, you can hardwire your Blink doorbell. Turn off power at the breaker, remove the old doorbell, and connect the wires to the Blink doorbell terminals. This provides continuous power and reduces battery changes.
Test the Doorbell
Press the button on the doorbell. You should hear a chime (if wired) and see a light flash. This confirms it’s powered and functional.
Mount the Doorbell (If Not Already Done)
Use the included mounting plate and screws to attach the doorbell to your doorframe. Use the wedge if you need to angle it for better coverage.
Step 5: Pair the Doorbell with the Sync Module
This is the core step—getting your doorbell to talk to the Sync Module.
Open the Blink App
Go back to the app and tap the “+” icon again.
Select “Add a Camera”
Choose “Add a Camera” from the menu. The app will search for nearby Blink devices.
Put the Doorbell in Pairing Mode
On the back of the doorbell, press and hold the setup button (small pinhole) for 5–10 seconds until the LED light starts blinking blue. This puts it in pairing mode.
Wait for Detection
The app will scan for the doorbell. This may take 10–30 seconds. Make sure you’re within 10 feet of the doorbell during this step.
Confirm Pairing
Once detected, the app will show the doorbell’s name and model. Tap “Add” to confirm. The Sync Module’s light may blink rapidly during this process.
Name Your Doorbell
Give your doorbell a name, like “Front Door” or “Porch Camera.” This helps identify it in the app.
Complete Setup
The app will finalize the connection. You’ll see a success message and live preview of the doorbell’s view.
Step 6: Test the Connection
Now that everything is connected, let’s make sure it’s working properly.
Check Live View
Tap on your doorbell in the app and select “Live View.” You should see a real-time video feed. If the image is blurry or delayed, check your Wi-Fi signal.
Test Motion Detection
Walk in front of the doorbell. The app should send a motion alert within a few seconds. You can adjust sensitivity in the settings.
Ring the Doorbell
Press the doorbell button. You should receive a notification and see a live feed. If you have a Blink Mini or Sync Module with chime, it may also sound an alert.
Review Recorded Clips
Go to the “Clip Library” in the app. You should see short video clips of recent motion or doorbell presses. If not, check your storage settings.
Troubleshooting Common Issues
Even with perfect setup, things can go wrong. Here’s how to fix the most common problems.
Doorbell Not Detected During Pairing
- Make sure the doorbell is in pairing mode (blinking blue light).
- Move closer to the Sync Module—stay within 10 feet.
- Restart the Sync Module by unplugging it for 10 seconds, then plugging it back in.
- Ensure your phone is connected to the same Wi-Fi network as the Sync Module.

- Reduce interference by moving the Sync Module away from cordless phones or baby monitors.
Pro Tips for a Smooth Setup
Want to avoid frustration? Follow these expert tips.
Use Lithium Batteries
Alkaline batteries drain quickly, especially in cold weather. Lithium batteries last up to 2x longer and perform better in extreme temperatures.
Keep the Sync Module Visible
Don’t hide the Sync Module in a cabinet or behind furniture. It needs a clear line of sight to your doorbell for reliable communication.
Update Firmware Regularly
Blink releases updates to improve performance and security. The app will notify you when updates are available. Always install them.
Set Up Motion Zones
Customize motion zones in the app to focus on important areas (like your walkway) and ignore others (like a busy street). This reduces false alerts.
Enable Clip Length and Quality Settings
Adjust video length (5–60 seconds) and resolution (standard or HD) based on your needs and internet speed.
Use a Dedicated Wi-Fi Network
If you have a guest network, consider setting up your Blink system on it. This keeps your main network secure and reduces congestion.
Label Your Devices
If you have multiple Blink cameras or doorbells, give each a clear name. This makes managing them much easier.
