By the end, you’ll have a fully functional, secure, and smart audio doorbell that enhances your home’s safety and convenience.

Let’s get started!

What You’ll Need Before You Begin

Before diving into the installation, make sure you have everything ready. Rushing this step can lead to frustration or even damage to your doorbell or wiring.

Here’s a checklist of what you’ll need:

• Arlo Audio Doorbell kit: Includes the doorbell unit, mounting bracket, screws, and wire nuts.
• Screwdriver (Phillips head): For removing the old doorbell and securing the new one.
• Voltage tester: To confirm the power is off and check your doorbell transformer voltage.
• Drill and drill bits (optional): Only if you need to make new holes for mounting.
• Smartphone or tablet: With the Arlo Secure app installed (available on iOS and Android).
• Wi-Fi network: 2.4 GHz Wi-Fi is required (5 GHz is not supported).
• Ladder (if needed): For reaching high doorbell locations.

Having these tools on hand will make the process smoother and safer.

Step 1: Check Compatibility and Power Requirements

Not all homes are ready for a smart doorbell out of the box. The Arlo Audio Doorbell requires a wired connection with specific electrical specs. Skipping this step could result in a doorbell that doesn’t power on or gets damaged.

Check Your Existing Doorbell Wiring

Most homes have a wired doorbell system with two wires leading from the doorbell button to a transformer. The Arlo Audio Doorbell uses these same wires for power.

To check:

1. Remove your current doorbell button from the wall.
2. Look at the wires—there should be two (usually labeled “Front” and “Trans”).
3. Make sure the wires are intact and not frayed or corroded.

If your home doesn’t have existing doorbell wiring, the Arlo Audio Doorbell won’t work. It’s not battery-powered like some other models. You’d need to run new wires or consider a wireless alternative.

Test Your Transformer Voltage

The Arlo Audio Doorbell needs a transformer that outputs between 16 and 24 volts AC. Most older homes have 8–12V transformers, which are too weak.

Here’s how to check:

1. Turn off power at the breaker.
2. Remove the old doorbell.
3. Use a voltage tester or multimeter to measure the voltage across the two wires.
4. If it’s below 16V, you’ll need to upgrade your transformer.

You can buy a compatible 16V or 24V doorbell transformer at most hardware stores. Installation is simple—just replace the old one near your chime or electrical panel.

Verify Wi-Fi Signal Strength

The doorbell connects to your home Wi-Fi network. If your front door is far from your router, the signal might be weak.

Use your phone to check the Wi-Fi signal at the doorbell location. If it’s weak (less than 2 bars), consider:

• Moving your router closer.
• Using a Wi-Fi extender.
• Installing a mesh network system.

A strong signal ensures reliable audio and quick alerts.

Step 2: Turn Off Power and Remove the Old Doorbell

Safety first! Working with electricity can be dangerous if you don’t take the right precautions.

Turn Off the Circuit Breaker

1. Go to your home’s electrical panel (breaker box).
2. Locate the breaker that controls your doorbell. It’s often labeled “Doorbell,” “Chime,” or “Front Door.”
3. Switch it to the OFF position.
4. Use a voltage tester on the doorbell wires to confirm no power is flowing.

Never assume the power is off—always test it.

Remove the Old Doorbell

1. Unscrew the old doorbell from the wall.
2. Gently pull it away to expose the wires.
3. Take a photo of the wiring setup for reference.
4. Loosen the terminal screws and disconnect the wires.
5. Cap the wires with wire nuts to prevent them from touching.

Set the old doorbell aside. You won’t need it anymore.

Step 3: Install the Arlo Mounting Bracket

The Arlo Audio Doorbell comes with a mounting bracket that secures the device to your wall. Proper installation ensures stability and optimal audio performance.

Position the Bracket

1. Hold the mounting bracket against the wall where you want to install the doorbell.
2. Use a level to make sure it’s straight.
3. Mark the screw holes with a pencil.

The ideal height is about 48 inches (4 feet) from the ground—chest level for most adults. This ensures clear audio and easy access.

Drill Holes (If Needed)

If your old doorbell used the same holes, you can reuse them. If not:

1. Drill pilot holes at the marked spots.
2. Insert wall anchors if you’re mounting into drywall or brick.

Secure the Bracket

1. Align the bracket with the holes.
2. Use the provided screws to attach it firmly to the wall.
3. Make sure it’s tight and doesn’t wobble.

The bracket has a built-in level—use it to double-check alignment.

Step 4: Connect the Wires to the Arlo Doorbell

Now it’s time to connect your home’s doorbell wires to the Arlo Audio Doorbell. This step powers the device and enables communication with your chime.

Prepare the Wires

1. Remove the wire nuts from the two doorbell wires.
2. Strip about 1/4 inch of insulation from the ends if needed.
3. Straighten the wires so they’re easy to insert.

Attach Wires to the Doorbell

The Arlo Audio Doorbell has two terminals: “Front” and “Trans.” It doesn’t matter which wire goes where—Arlo’s design is polarity-free.

1. Loosen the terminal screws on the back of the doorbell.
2. Insert one wire into the “Front” terminal and tighten the screw.
3. Insert the other wire into the “Trans” terminal and tighten.
4. Give the wires a gentle tug to ensure they’re secure.

Attach the Doorbell to the Bracket

1. Align the doorbell with the mounting bracket.
2. Slide it down until it clicks into place.
3. Use the included security screw to lock it in (prevents theft).

You’ll hear a click when it’s properly seated.

Step 5: Restore Power and Test the Doorbell

With everything connected, it’s time to turn the power back on and see if it works.

Turn the Breaker Back On

1. Go to your electrical panel.
2. Switch the doorbell breaker to ON.
3. Wait 10–15 seconds for the system to power up.

Test the Doorbell

1. Press the doorbell button.
2. Listen for a chime inside your home.
3. Check if the Arlo doorbell’s LED light turns on (usually blue or white).

If the chime sounds and the light activates, the hardware is working. If not, double-check your wiring and transformer voltage.

Step 6: Set Up the Arlo Audio Doorbell in the App

Now for the fun part—connecting your doorbell to your smartphone and customizing settings.

Download and Open the Arlo Secure App

If you haven’t already:

1. Download the Arlo Secure app from the App Store (iOS) or Google Play (Android).
2. Create an account or log in.

Step 7: Customize Settings and Notifications

Make your Arlo Audio Doorbell work for your lifestyle with these settings.

Enable Motion Alerts

1. Go to the device settings in the app.
2. Turn on “Motion Detection.”
3. Adjust the sensitivity (low, medium, high).
4. Set activity zones if you want alerts only from certain areas (e.g., walkway, not street).

You’ll get push notifications when motion is detected.

Set Up Two-Way Audio

This lets you talk to visitors remotely:

1. Ensure “Two-Way Audio” is enabled in settings.
2. Test it by pressing the doorbell and speaking through your phone.
3. Adjust microphone and speaker volume for clarity.

Customize Chime Sounds (Optional)

If you have an Arlo SmartHub or compatible chime:

1. Pair the chime in the app.
2. Choose from different chime tones.
3. Set volume and duration.

Schedule Do Not Disturb

Avoid late-night alerts:

1. Go to “Do Not Disturb” in settings.
2. Set a schedule (e.g., 10 PM to 7 AM).
3. Choose whether to silence alerts or just the chime.

Troubleshooting Common Installation Issues

Even with careful installation, problems can happen. Here’s how to fix the most common ones.

Doorbell Doesn’t Power On

• Check the breaker: Make sure power is restored.
• Test voltage: Use a multimeter to confirm 16–24V at the wires.
