Before touching any wires, gather the right tools and materials. Having everything ready will save time and reduce frustration.
Tools and Materials
- Arlo Doorbell Wired (with mounting bracket and screws)
- Screwdriver (Phillips and flathead)
- Voltage tester (non-contact type recommended)
- Drill and drill bits (if mounting on brick, stucco, or concrete)
- Level (to ensure the doorbell is straight)
- Pencil or marker
- Wire strippers (optional, if trimming wires)
- Electrical tape (for temporary wire protection)
- Ladder (if your doorbell is high up)
Check Your Existing Doorbell System
The Arlo Doorbell Wired requires a compatible transformer and wiring. Most older homes have a doorbell system, but not all are suitable.
Check the transformer—usually located near your electrical panel, furnace, or attic. It should output between 16 and 24 volts AC. If your current transformer is 8V or 12V, it won’t provide enough power, and you’ll need to upgrade it.
You can test the voltage with a multimeter or hire an electrician if you’re unsure. Arlo recommends a 16V transformer with at least 20VA (volt-amperes) for optimal performance.
Also, ensure your existing doorbell wires are in good condition. Frayed or corroded wires may need replacement.
Download the Arlo App
Download the Arlo Secure app on your smartphone (available on iOS and Android). You’ll use this app to sync your doorbell, adjust settings, and view live video.
Create an Arlo account if you don’t already have one. Keep your Wi-Fi network name (SSID) and password handy—you’ll need them during setup.
Step 1: Turn Off the Power
Safety first! Working with electricity can be dangerous if you skip this step.
Locate Your Circuit Breaker
Go to your home’s main electrical panel. Look for the breaker labeled “doorbell,” “chime,” or something similar. If there’s no label, you may need to test breakers by turning them off one at a time and checking if your existing doorbell stops working.
Turn Off the Breaker
Switch the breaker to the “OFF” position. Use a non-contact voltage tester to confirm the power is off. Touch the tester near the doorbell wires—if it doesn’t beep or light up, the power is safely off.
Pro Tip: Place a piece of tape over the breaker switch to prevent someone from accidentally turning it back on while you’re working.
Step 2: Remove the Old Doorbell
Now that the power is off, it’s time to remove your existing doorbell.
Unscrew the Old Doorbell
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the device away from the wall to expose the wires.
Disconnect the Wires
You’ll see two wires connected to the back of the doorbell. These are typically labeled “Front” and “Trans” (transformer). Loosen the screws or release the clips holding the wires, then carefully pull them free.
Important: Don’t let the wires slip back into the wall. Use electrical tape to wrap the ends and keep them exposed.
Remove the Old Mounting Plate (If Needed)
If your old doorbell had a mounting plate, unscrew it. The Arlo Doorbell Wired comes with its own bracket, so you’ll install that next.
Step 3: Install the Arlo Mounting Bracket
The mounting bracket ensures your doorbell is secure and properly aligned.
Position the Bracket
Hold the Arlo mounting bracket against the wall where you want to install the doorbell. Use a level to make sure it’s straight. Mark the screw holes with a pencil.
Tip: The ideal height is about 48 inches from the ground—eye level for most visitors.
Drill Pilot Holes (If Necessary)
If you’re mounting on wood, you can screw directly into the wall. For brick, stucco, or concrete, use a drill to create pilot holes. Insert wall anchors if needed for extra support.
Secure the Bracket
Line up the bracket with the marks and screw it into place. Make sure it’s tight and doesn’t wobble.
Step 4: Connect the Wires to the Arlo Doorbell
Now it’s time to connect your doorbell wires to the Arlo device.
Prepare the Wires
If the wire ends are frayed or too short, use wire strippers to expose about 1/4 inch of copper. Twist the strands gently to keep them neat.
Attach the Wires
The Arlo Doorbell Wired has two terminal screws on the back: one marked “Front” and one marked “Trans.” It doesn’t matter which wire goes where—Arlo’s design is polarity-independent.
Loosen the screws, insert each wire into its corresponding terminal, and tighten the screws securely. Give the wires a gentle tug to ensure they’re held firmly.
Pro Tip: If your wires are too short, you can use wire extenders or pigtail connectors. Just make sure all connections are insulated with electrical tape.
Step 5: Attach the Arlo Doorbell to the Bracket
With the wires connected, it’s time to mount the doorbell.
Align the Doorbell
Hold the Arlo Doorbell against the mounting bracket. The bottom of the device should snap into place, while the top attaches with a screw.
Secure with the Top Screw
Use the provided security screw and a screwdriver to fasten the top of the doorbell to the bracket. This prevents tampering and ensures a snug fit.
Note: Don’t overtighten—this could crack the plastic housing.
Step 6: Turn the Power Back On
Now that everything is connected, restore power.
Flip the Breaker
Go back to your electrical panel and turn the breaker back to the “ON” position.
Check for Power
The Arlo Doorbell should light up or show a status LED. If it doesn’t, double-check your wiring and breaker.
Step 7: Set Up the Arlo Doorbell in the App
The final step is syncing your doorbell with the Arlo app.
Open the Arlo Secure App
Launch the app and log in to your account. Tap the “+” icon to add a new device.
Select “Doorbell”
Choose “Doorbell” from the list of device types. The app will guide you through the setup process.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the Arlo Doorbell. This links the device to your account.
Connect to Wi-Fi
Select your home Wi-Fi network and enter the password. The doorbell will connect to your network. This may take a minute or two.
Tip: Make sure your Wi-Fi signal is strong at the doorbell location. If not, consider using a Wi-Fi extender.
Complete Setup
Follow the on-screen prompts to name your doorbell (e.g., “Front Door”), set motion zones, and enable notifications. You can also adjust video quality, night vision, and chime settings.
Step 8: Test Your Arlo Doorbell Wired
Before calling the job done, test everything.
Ring the Doorbell
Press the button on the Arlo Doorbell. You should hear a chime (if connected to a mechanical chime) and receive a notification on your phone.
Check Live View
Open the Arlo app and tap “Live View” to see the camera feed. Make sure the image is clear and the audio works.
Test Two-Way Audio
Speak through the app and listen for your voice on the doorbell. Also, talk near the doorbell and check if you can hear it in the app.
Verify Motion Detection
Walk in front of the doorbell to trigger motion alerts. Adjust sensitivity in the app if needed.
Troubleshooting Common Installation Issues
Even with careful installation, problems can happen. Here’s how to fix the most common issues.
Doorbell Won’t Power On
- Check that the breaker is on.
- Use a voltage tester to confirm power at the wires.
- Ensure wires are securely connected to the terminals.
- Verify the transformer outputs 16–24V AC.
No Video or Poor Image Quality
- Check Wi-Fi signal strength at the doorbell.
- Move your router closer or use a Wi-Fi extender.
- Restart the doorbell by turning the breaker off and on.
- Update the Arlo app and doorbell firmware.
Doorbell Rings but No Notification
- Ensure notifications are enabled in the app and phone settings.
- Check that the doorbell is connected to Wi-Fi.
- Restart the app and re-sync the device if needed.
Chime Doesn’t Ring
- Confirm your mechanical chime is compatible (Arlo supports most).
- Check wiring connections at both the doorbell and chime unit.
- Adjust chime settings in the Arlo app.
App Can’t Find the Doorbell
- Make sure the doorbell is powered and in pairing mode (LED blinking).
- Restart your phone and router.
- Try scanning the QR code again.
Tips for a Professional-Looking Installation
A clean install not only looks better but also improves performance.
Hide Wires Neatly
Use wire clips or conduit to keep exposed wires tidy. Avoid loose loops that could get damaged.
Use a Decorative Backplate (Optional)
Arlo offers optional backplates that cover gaps and give a polished look. These are especially useful if your old doorbell left a large hole.
Label Your Breaker
After installation, label the breaker “Doorbell” so you (or others) can easily find it in the future.
Schedule Regular Checks
Every few months, check that the doorbell is secure, the lens is clean, and the app is up to date.
