- Blink Video Doorbell (model compatible with your home)
- Blink Sync Module 2 (included in most kits or sold separately)
- Smartphone or tablet with the Blink app installed (iOS or Android)
- Screwdriver (usually Phillips head)
- Drill and drill bits (if mounting on brick, concrete, or hard surfaces)
- Wire strippers (if reusing existing doorbell wires)
- Electrical tape (for securing wires)
- Level (to ensure the doorbell is straight)
- Optional: Wire nuts (if extending or connecting wires)
Make sure your home’s doorbell wiring meets Blink’s requirements. The doorbell should be powered by a transformer that delivers between 8 and 24 volts AC. Most modern homes meet this standard, but older homes may need an upgrade. You can check this by looking at your existing doorbell transformer, usually located near your electrical panel, furnace, or doorbell chime.
Step 1: Turn Off Power and Remove the Old Doorbell
Safety first! Before touching any wires, turn off the power to your doorbell at the circuit breaker. This prevents accidental shocks or short circuits. Use a non-contact voltage tester to confirm the wires are not live.
Remove the Existing Doorbell Button
Unscrew the old doorbell button from the wall. Gently pull it away to expose the two wires connected to it. These wires carry low voltage and are safe to handle once the power is off. If the wires are short, use wire strippers to expose about 1/4 inch of copper on each end. This will help ensure a solid connection with your new Blink doorbell.
Label the Wires (Optional but Helpful)
If you’re unsure which wire goes where, label them with tape (e.g., “Front” and “Transformer”) before disconnecting. This makes reinstallation easier and reduces confusion later.
Check the Chime Unit
Open your indoor doorbell chime (usually located in a hallway or near the front door). Look for the terminals labeled “Front” or “Transformer.” These are the wires that connect to your doorbell button. Ensure they’re securely connected and not frayed. If your chime is mechanical (with physical bells), it should work with Blink. If it’s a digital chime, verify compatibility on Blink’s website.
Step 2: Install the Blink Sync Module 2
The Sync Module 2 is the brain of your Blink system. It connects your doorbell to your Wi-Fi network and enables cloud storage, motion alerts, and remote viewing. It must be installed indoors, within 100 feet of your doorbell and your router.
Choose a Location for the Sync Module
Pick a spot near an electrical outlet, ideally between your router and your front door. Avoid placing it behind metal objects, thick walls, or near microwaves and cordless phones, which can interfere with the signal. A central hallway or living room is often ideal.
Plug In and Power On
Plug the Sync Module into a wall outlet. The LED light will blink blue, indicating it’s in setup mode. Wait about 30 seconds for it to initialize. Once the light turns solid blue, it’s ready to pair with the Blink app.
Connect to Wi-Fi via the App
Open the Blink app on your smartphone. If you don’t have an account, create one using your email and a secure password. Tap “Add a System” and follow the prompts to add a new Sync Module. The app will guide you through connecting the module to your 2.4 GHz Wi-Fi network (Blink does not support 5 GHz). Enter your Wi-Fi password when prompted.
Once connected, the Sync Module’s LED will turn solid green, confirming a successful connection. You’ll also see the module listed in the app under “Systems.”
Step 3: Mount the Blink Doorbell
Now it’s time to install the doorbell itself. Blink offers two mounting options: using existing wires or going completely wireless with batteries. We’ll cover both methods.
Option A: Wired Installation (Recommended for Reliability)
If your doorbell has existing wires, this method provides continuous power and eliminates the need to recharge batteries.
- Hold the Blink doorbell against the wall where you want to mount it. Use a level to ensure it’s straight.
- Mark the screw holes with a pencil.
- Drill pilot holes if mounting on brick, stucco, or concrete.
- Thread the existing doorbell wires through the back of the Blink mount.
- Secure the mount to the wall using the provided screws.
- Connect the wires to the terminals on the back of the doorbell (polarity doesn’t matter—Blink is non-polarized).
- Snap the doorbell onto the mount until it clicks into place.
Option B: Battery-Powered Installation
If you don’t have doorbell wires or prefer a wireless setup, Blink doorbells can run on two AA lithium batteries (included). This option is great for renters or homes without wiring.
- Insert the batteries into the compartment on the back of the doorbell.
- Attach the mounting plate to the wall using screws or adhesive strips (included).
- Snap the doorbell onto the plate.
Tip: Even if you use batteries, you can still connect the wires to the terminals. This provides backup power and extends battery life, especially in cold weather.
Step 4: Pair the Doorbell with the Sync Module
With the doorbell mounted and powered, it’s time to connect it to the Sync Module via the Blink app.
Open the Blink App and Add the Doorbell
In the app, go to your system and tap “Add a Camera.” Select “Doorbell” from the list. The app will search for nearby devices. When your doorbell appears, tap it to begin pairing.
Sync the Devices
Press and hold the button on the front of your Blink doorbell for 5 seconds until the LED flashes red. This puts it into pairing mode. The app will detect the signal and guide you through the final steps.
Test the Connection
Once paired, the app will show a live video feed from your doorbell. Tap the button on the doorbell to test the chime. If you have a wired installation, your indoor chime should ring. If not, you’ll receive a notification on your phone.
Step 5: Configure Settings and Preferences
Now that your doorbell is connected, customize it to suit your lifestyle and security needs.
Set Up Motion Detection
In the app, go to “Motion Settings” and adjust the sensitivity. High sensitivity detects smaller movements (like a cat walking by), while low sensitivity reduces false alerts. You can also set motion zones—areas where you want alerts (e.g., the front walkway) and areas to ignore (e.g., a busy street).
Enable Notifications
Turn on push notifications so you’re alerted whenever motion is detected or the doorbell is pressed. You can choose to receive alerts for all events or only during certain hours (e.g., nighttime only).
Adjust Video Quality and Recording Length
Blink doorbells record in HD (1080p) by default. You can lower the resolution to save bandwidth or extend battery life. Recording length can be set from 5 to 60 seconds. Longer recordings capture more context but use more storage.
Set Up Two-Way Audio
Enable two-way talk so you can speak to visitors through the app. Test it by pressing the talk button and saying “Hello.” Adjust the microphone and speaker volume for clarity.
Schedule Activity Zones and Quiet Hours
Use “Quiet Hours” to silence notifications during specific times (e.g., 10 PM to 7 AM). You can also disable motion detection entirely during these periods if desired.
Step 6: Test and Troubleshoot
After setup, run a few tests to ensure everything works correctly.
Test the Doorbell Button
Press the button and confirm the chime rings (if wired) or you receive a phone notification. Check the video quality and audio clarity in the app.
Test Motion Detection
Check Wi-Fi Signal Strength
In the app, go to “System Settings” > “Sync Module” > “Signal Strength.” A strong signal (green) ensures reliable performance. If it’s weak (red or yellow), consider moving the Sync Module closer to the doorbell or using a Wi-Fi extender.
Troubleshooting Common Issues
Even with careful installation, you might encounter a few hiccups. Here’s how to fix the most common problems.
Doorbell Not Pairing with Sync Module
- Ensure both devices are powered and within range.
- Reset the doorbell by holding the button for 20 seconds until the LED flashes red, then retry pairing.
- Restart the Sync Module by unplugging it for 10 seconds.
No Chime Sound (Wired Installation)
- Double-check wire connections at both the doorbell and chime.
- Verify the transformer voltage (should be 8–24V AC).
- Test the chime with a multimeter to ensure it’s receiving power.
Poor Video Quality or Lag
- Move the Sync Module closer to the doorbell or router.
- Reduce video resolution in the app.
- Ensure your Wi-Fi network isn’t overloaded with devices.
