What You’ll Need Before You Begin

Before touching any wires, gather all the tools and materials. Having everything ready saves time and reduces frustration.

Tools and Materials List

Arlo Wired Video Doorbell (with mounting bracket and screws)
Smartphone with the Arlo app installed (iOS or Android)
Screwdriver (Phillips head, typically #2)
Voltage tester (non-contact type recommended)
Wire strippers (if you need to trim or re-strip wires)
Electrical tape
Wire nuts (usually included, but extras are helpful)
Drill and drill bits (only if mounting into brick, concrete, or hard surfaces)
Level (to ensure the doorbell is straight)
Ladder (if your doorbell is high up)
Safety gloves and goggles (optional but recommended)

Check Your Doorbell System Compatibility

Not all homes are ready for the Arlo wired video doorbell out of the box. The device requires a 16–24V AC transformer with a minimum of 30VA (volt-amperes) to function properly. Most modern doorbells meet this, but older homes may have underpowered transformers.

To check:

Locate your doorbell transformer. It’s usually near your electrical panel, in the basement, attic, or garage.
Look for a label that shows voltage (V) and VA rating. If it says 16V or higher and 30VA or more, you’re good to go.
If your transformer is below 16V or under 30VA, you’ll need to upgrade it before installing the Arlo doorbell. This may require an electrician.

Pro Tip: If you’re unsure, take a photo of the transformer label and consult Arlo’s compatibility checker online or contact their support team.

Step 1: Turn Off the Power

Safety first! Even though doorbell wires carry low voltage, they’re still connected to your home’s electrical system. Turning off the power prevents shocks, short circuits, or damage to the doorbell.

Locate Your Circuit Breaker

Go to your main electrical panel (breaker box).
Look for a breaker labeled “Doorbell,” “Chime,” or “Front Door.” If there isn’t one, you may need to test breakers by turning them off one at a time.
Turn off the correct breaker. Use a non-contact voltage tester on the doorbell wires later to confirm power is off.

Test the Wires

Remove the faceplate of your existing doorbell (usually held by one or two screws).
Gently pull the wires out and separate them.
Touch the voltage tester to each wire. If it beeps or lights up, power is still on—double-check the breaker.
Only proceed when the tester confirms no voltage.

Important: Never assume the power is off. Always test. Even low-voltage shocks can be dangerous, and live wires can fry your new doorbell.

Step 2: Remove the Old Doorbell

Now that power is off, it’s time to remove your existing doorbell.

Unscrew the Faceplate

Use a screwdriver to remove the screws holding the old doorbell to the wall.
Gently pull the unit away from the wall. The wires will be connected to two terminals (usually labeled “Front” and “Trans”).

Disconnect the Wires

Loosen the terminal screws and carefully remove the wires.
If the wires are short or damaged, use wire strippers to expose fresh copper (about 1/4 inch).
Twist the wire ends to keep them neat and prevent fraying.

Cap the Wires (Temporarily)

Twist a wire nut onto each exposed wire to prevent them from touching or shorting.
Tape the wire nuts with electrical tape for extra security.
Tuck the wires back into the wall slightly so they don’t fall in.

Note: Don’t cut the wires unless necessary. You’ll need them to connect to the Arlo doorbell.

Step 3: Prepare the Arlo Doorbell for Installation

Unbox your Arlo wired video doorbell and get it ready for mounting.

Inspect the Components

You should have: the doorbell unit, mounting bracket, screws, wire connectors, and a wedge (for angling).
Check for any visible damage. If anything is broken, contact Arlo support before proceeding.

Attach the Mounting Bracket

Hold the bracket against the wall where the old doorbell was.
Use a level to make sure it’s straight.
Mark the screw holes with a pencil.
If mounting into wood, you can screw directly in. For brick or concrete, drill pilot holes and use wall anchors.
Secure the bracket with the provided screws.

Optional: Use the Wedge for Better Viewing Angle

If your doorbell is mounted too high or too low, the included wedge can help angle the camera downward.
Attach the wedge to the bracket before mounting, or between the bracket and the doorbell.
This improves motion detection and ensures visitors’ faces are clearly visible.

Pro Tip: Test the angle by holding the doorbell in place before final mounting. Make sure it captures the walkway and doesn’t point at a wall or bush.

Step 4: Connect the Wires to the Arlo Doorbell

This is the most critical step—connecting the wires correctly ensures power and functionality.

Identify the Wires

You should have two wires: one from the doorbell chime (usually labeled “Front”) and one from the transformer.
It doesn’t matter which wire goes where—Arlo doorbells are non-polarized. But keep them separate to avoid shorts.

Strip and Prepare the Wires

If the wire ends are frayed or too short, strip about 1/4 inch of insulation.
Twist the copper strands tightly.

Connect to the Doorbell

On the back of the Arlo doorbell, you’ll see two terminal screws or push-in connectors.
Loosen the screws (if applicable) and insert one wire under each terminal.
Tighten the screws securely. The wire should not pull out when gently tugged.
If using push-in connectors, insert the stripped wire fully and ensure it’s locked in.

Secure with Wire Nuts (Optional but Recommended)

Some models allow you to connect wires directly to the doorbell. Others recommend using wire nuts for a more secure connection.
If your model supports it, twist the doorbell’s lead wires to the home wires and cap with a wire nut.
Wrap the connection with electrical tape for added protection.

Warning: Do not let the bare wires touch each other. This can cause a short circuit or damage the doorbell.

Step 5: Mount the Arlo Doorbell

Now it’s time to attach the doorbell to the wall.

Align and Secure

Hold the doorbell against the mounting bracket.
Slide it into place until it clicks or sits flush.
Use the provided security screw (usually a small hex screw) to lock it in place. This prevents theft or tampering.
Use a hex key (included) to tighten the screw.

Check the Fit

Make sure the doorbell is level and secure.
Gently tug on it to ensure it doesn’t wobble.
If it moves, re-tighten the mounting screws or bracket.

Tidy Up the Wires

Tuck any excess wire back into the wall cavity.
Use electrical tape to bundle loose wires if needed.
Ensure no wires are pinched between the doorbell and the wall.

Pro Tip: If you’re mounting on siding or uneven surfaces, use foam tape or a backplate to create a flat, secure surface.

Step 6: Restore Power and Test

You’re almost done! Now it’s time to turn the power back on and see if everything works.

Turn On the Breaker

Go back to your electrical panel.
Turn the doorbell breaker back on.
Wait 10–15 seconds for the system to power up.

Check for Lights

The Arlo doorbell should light up with a solid or blinking LED.
A solid white or blue light usually means it’s powered and ready.
If no light appears, double-check wiring and power.

Test the Doorbell

Press the doorbell button.
Listen for the chime inside your home.
If your chime doesn’t ring, the wiring may be reversed or the chime unit may not be compatible.

Note: Some mechanical chimes may not work with smart doorbells. If your chime doesn’t ring, you may need a digital chime or to bypass the chime (see troubleshooting).

Step 7: Set Up the Arlo App

The Arlo app is your control center for video, alerts, and settings. Let’s get it configured.

Download and Open the App

Download “Arlo” from the Apple App Store or Google Play.
