Step 1: Turn Off Power and Verify Compatibility
Safety comes first. Never work on electrical components without turning off the power.
Turn Off the Circuit Breaker
Locate your home’s electrical panel and find the breaker that controls your doorbell circuit. It’s often labeled “doorbell,” “chime,” or “front door.” Flip it to the OFF position.
To double-check, press your existing doorbell button. If the chime doesn’t sound, the power is off. For extra safety, use a non-contact voltage tester near the doorbell wires to confirm no electricity is flowing.
Check Doorbell Compatibility
The G4 Doorbell Pro works with most standard doorbell systems, but you need to verify a few things:
- Transformer voltage: Your doorbell transformer should output between 8V and 24V AC. Most homes use 16V, which is ideal. You can find this info on the transformer (usually located in the attic, basement, or near the furnace).
- Chime type: The G4 Doorbell Pro supports both mechanical (traditional) and digital (electronic) chimes. If you have a digital chime, use the included chime kit to ensure compatibility.
- Wi-Fi signal: Your front door should be within range of your Wi-Fi router. If not, consider a Wi-Fi extender or mesh network.
If your system doesn’t meet these requirements, you may need to upgrade your transformer or consult an electrician.
Step 2: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, you’ll need to remove it first.
Unscrew the Old Faceplate
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the unit away to expose the wires.
Disconnect the Wires
Take a photo of the wiring setup for reference. Then, loosen the terminal screws and carefully remove the wires. Label them if needed (e.g., “Front” and “Trans”) to avoid confusion later.
Tuck Wires Safely
Push the wires back into the wall slightly, but don’t let them disappear completely. You’ll need them for the new installation. Use electrical tape to secure them if they’re loose.
Step 3: Prepare the Mounting Location
The G4 Doorbell Pro should be mounted at a height of 48 inches (4 feet) from the ground for optimal viewing angle.
Choose the Right Spot
Pick a location that:
- Faces the approach to your door
- Is within Wi-Fi range
- Is protected from direct rain (under an eave or porch)
- Has enough space for the mounting bracket
Avoid placing it too close to windows or reflective surfaces, which can cause glare in videos.
Mark and Drill Holes
Hold the mounting bracket against the wall at the desired height. Use a level to ensure it’s straight. Mark the screw holes with a pencil.
If mounting on drywall, use the included wall anchors. For brick, stucco, or concrete, drill pilot holes with a masonry bit and use appropriate anchors.
Step 4: Connect the Wires to the G4 Doorbell Pro
Now it’s time to wire the doorbell. This step is crucial for power and functionality.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch of insulation from each wire. This exposes fresh copper for a solid connection.
Attach Wires to the Terminal Block
The G4 Doorbell Pro uses a terminal block with two screws: “Front” and “Trans.”
- Connect one wire to “Front” (usually the wire from the doorbell button)
- Connect the other to “Trans” (the wire from the transformer)
Tighten the screws securely, but don’t over-tighten. The wires should be snug and not loose.
Use Wire Connectors (If Needed)
If your wires are too short or damaged, use the included butt connectors to extend them. Strip both ends, insert into the connector, and crimp with pliers.
Secure the Wires
Tuck the connected wires back into the wall neatly. Avoid pinching or bending them sharply.
Step 5: Mount the G4 Doorbell Pro
With the wires connected, it’s time to attach the doorbell to the wall.
Attach the Mounting Bracket
Align the bracket with the drilled holes and secure it with screws. Make sure it’s level and tight.
Snap the Doorbell into Place
The G4 Doorbell Pro slides onto the bracket and clicks into place. Give it a gentle tug to ensure it’s secure.
Adjust the Angle (Optional)
The doorbell has a slight tilt adjustment. Loosen the screws on the back slightly, angle the unit for the best view, then retighten.
Step 6: Restore Power and Test
Now that everything is connected, it’s time to power up and test.
Turn the Breaker Back On
Go to your electrical panel and flip the doorbell breaker to ON.
Check for Power
The G4 Doorbell Pro should light up with a blue LED ring. If it doesn’t, double-check your wiring and breaker.
Test the Doorbell
Press the button on the doorbell. You should hear a chime inside (if connected) and see the LED flash. If using the app, you’ll receive a notification.
Step 7: Set Up the UniFi Protect App
The G4 Doorbell Pro works with the UniFi Protect app, available for iOS and Android.
Download and Open the App
Search for “UniFi Protect” in your app store and install it. Open the app and sign in with your Ubiquiti account. If you don’t have one, create it for free.
Add the Doorbell to Your System
- Tap the “+” icon to add a new device.
- Select “Doorbell” and follow the on-screen prompts.
- Scan the QR code on the back of the G4 Doorbell Pro or enter the serial number manually.
Connect to Wi-Fi
The app will guide you through connecting the doorbell to your Wi-Fi network. Make sure your phone is on the same network. Enter your Wi-Fi password when prompted.
Configure Settings
Once connected, customize your preferences:
- Set motion zones (e.g., only alert for people near the door)
- Adjust video quality and recording settings
- Enable two-way audio
- Set up smart detection (people, vehicles, packages)
Test Two-Way Audio
Tap the microphone icon in the app and speak. You should hear your voice through the doorbell’s speaker. Ask someone outside to press the button and talk back to test the full experience.
Step 8: Final Adjustments and Tips
Now that your G4 Doorbell Pro is installed and working, here are some final tips to optimize performance.
Ensure Strong Wi-Fi Signal
A weak signal can cause lag or disconnections. Use the app’s signal strength indicator to check. If it’s low, consider moving your router, using a Wi-Fi extender, or upgrading to a mesh system.
Adjust Motion Sensitivity
Too many false alerts? Lower the motion sensitivity in the app or narrow the detection zones. Focus on the walkway and ignore trees or passing cars.
Keep the Lens Clean
Dust, rain, and fingerprints can blur the camera. Wipe the lens gently with a microfiber cloth every few weeks.
Enable Smart Alerts
Use AI-powered detection to only receive alerts for people, not animals or shadows. This reduces notification fatigue.
Set Up Recording Rules
Choose when the doorbell records: always, only when motion is detected, or during specific hours. Store footage on a UniFi NVR or cloud (if subscribed).
Troubleshooting Common Issues
Even with careful installation, you might run into problems. Here’s how to fix the most common ones.
Doorbell Won’t Power On
- Check the breaker—make sure it’s on.
- Test the voltage at the wires with a multimeter (should be 8–24V AC).
- Ensure wires are securely connected and not reversed.
- Try a different transformer if voltage is too low.
No Chime Sound
- For mechanical chimes: ensure wires are connected properly and the chime is functional.
- For digital chimes: install the included chime kit according to the instructions.
- Check if the chime is muted in the app settings.
Weak or Dropping Wi-Fi Signal
- Move the router closer or add a Wi-Fi extender.
- Switch to a less congested Wi-Fi channel.
- Use a wired connection via a UniFi Flex Mini switch (advanced setup).
App Not Connecting to Doorbell
- Restart the doorbell by holding the button for 10 seconds.
- Reinstall the app or update it to the latest version.
- Ensure your phone and doorbell are on the same Wi-Fi network.
Blurry or Dark Video
- Clean the lens with a soft cloth.
- Adjust the doorbell angle to avoid backlighting (e.g., direct sun).
- Enable HDR in the app for better contrast.
