What You’ll Need Before You Begin
Before you touch a single wire, it’s important to gather all the tools and materials you’ll need. Having everything ready will save time and prevent frustration during the installation.
Here’s a checklist of what you’ll need:
- Arlo wired doorbell kit: This includes the doorbell unit, mounting plate, screws, wire connectors, and a mounting wedge (if needed).
- Screwdriver (Phillips and flathead): For removing the old doorbell and securing the new one.
- Voltage tester: To confirm the power is off before working on wires.
- Drill and drill bits (optional): Only if you need to create new mounting holes or run wires.
- Level: To ensure the doorbell is mounted straight.
- Smartphone or tablet: With the Arlo app installed and your Arlo account set up.
- Wi-Fi network: The doorbell needs a 2.4 GHz Wi-Fi connection (5 GHz is not supported).
- Ladder (if needed): For reaching high doorbell locations.
Having these items on hand will make the installation smoother and safer.
Step 1: Check Compatibility with Your Existing Doorbell
Not all doorbell systems are compatible with the Arlo wired doorbell. Before you begin, you need to verify that your current setup meets the requirements.
Check Your Transformer Voltage
The Arlo wired doorbell requires a transformer that outputs between 8 and 24 volts AC (alternating current). Most older homes have transformers in this range, but it’s best to confirm.
To check:
- Locate your doorbell transformer. It’s usually found in the basement, attic, garage, or near your electrical panel.
- Look for a label that lists the voltage output. It should say something like “16V AC” or “24V AC.”
- If you can’t find the transformer or the label is unclear, use a multimeter to test the voltage at the doorbell wires (only after turning off power).
If your transformer is outside the 8–24V range, you may need to replace it before installing the Arlo doorbell.
Confirm You Have a Mechanical Chime
The Arlo wired doorbell is designed to work with traditional mechanical chimes (the kind with physical bells or strikers). It is not compatible with digital or electronic chimes that use speakers.
To check:
- Listen to your current doorbell sound. Mechanical chimes produce a clear “ding-dong” tone.
- If your chime plays a melody or uses a speaker, it’s likely digital and not compatible.
If you have a digital chime, you may need to replace it with a mechanical one or consider a wireless Arlo doorbell instead.
Ensure Wi-Fi Coverage at the Door
Since the Arlo doorbell relies on Wi-Fi for video streaming and alerts, you need a strong 2.4 GHz signal at your front door.
To test:
- Stand at your door with your smartphone and check the Wi-Fi signal strength.
- If the signal is weak, consider using a Wi-Fi extender or mesh network to boost coverage.
A weak signal can cause delays, dropped connections, or poor video quality.
Step 2: Turn Off the Power
Safety is the most important part of any electrical project. Working on live wires can result in electric shock, injury, or damage to your doorbell.
Locate the Correct Circuit Breaker
Your doorbell is connected to a low-voltage circuit, but it still draws power from your home’s electrical system. You need to turn off the breaker that controls it.
To find the right breaker:
- Look for a labeled breaker that says “doorbell,” “chime,” or “front door.”
- If it’s not labeled, turn off breakers one at a time and test the doorbell until it stops working.
- Once you’ve identified the correct breaker, switch it to the “off” position.
Test the Wires with a Voltage Tester
Even after turning off the breaker, it’s wise to double-check that the wires are not live.
To test:
- Remove the old doorbell from the wall.
- Carefully separate the two wires.
- Touch the voltage tester to each wire. If the tester lights up or beeps, the power is still on—double-check the breaker.
- Only proceed when the tester confirms no voltage is present.
Never skip this step. It only takes a few seconds and could prevent a serious accident.
Step 3: Remove the Old Doorbell
Now that the power is off and confirmed safe, you can remove your existing doorbell.
Unscrew the Old Unit
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the unit away from the wall.
Disconnect the Wires
You’ll see two wires connected to the back of the old doorbell. These are typically labeled “Front” and “Trans,” but the labels aren’t always present.
To disconnect:
- Loosen the terminal screws or pull the wires out of the back (depending on the model).
- Carefully pull the wires free, making sure they don’t fall back into the wall.
- If the wires are short, use electrical tape to mark which one was connected to which terminal (e.g., “Front” or “Trans”).
Inspect the Wiring
Check the condition of the wires. If they’re frayed, corroded, or damaged, trim them back with wire strippers and expose fresh copper. You’ll need about ½ inch of bare wire for a secure connection.
Step 4: Install the Arlo Mounting Plate
The Arlo doorbell comes with a mounting plate that attaches to the wall and holds the doorbell securely.
Position the Mounting Plate
Hold the mounting plate against the wall where you want to install the doorbell. The ideal height is about 48 inches from the ground—this ensures the camera captures visitors’ faces clearly.
Use a level to make sure the plate is straight. Mark the screw holes with a pencil.
Drill Pilot Holes (If Needed)
If you’re not reusing the existing holes, drill pilot holes into the wall at the marked spots. Use a drill bit slightly smaller than the screws to ensure a tight fit.
For brick, stucco, or concrete walls, use a masonry bit and wall anchors.
Attach the Mounting Plate
Line up the plate with the holes and secure it using the provided screws. Make sure it’s tight and level.
If your doorframe is uneven or you want a better angle, use the included mounting wedge. Attach it to the plate before mounting to tilt the doorbell slightly toward the walkway.
Step 5: Connect the Wires to the Arlo Doorbell
Now it’s time to connect the doorbell wires to the new Arlo unit.
Prepare the Wires
Strip about ½ inch of insulation from the ends of both wires if you haven’t already. Twist the exposed copper to keep the strands together.
Connect to the Terminal Screws
The Arlo doorbell has two terminal screws on the back—usually labeled “Front” and “Trans.” It doesn’t matter which wire goes where, as the doorbell is not polarity-sensitive.
To connect:
- Loosen the terminal screws slightly.
- Insert one wire under each screw.
- Tighten the screws to secure the wires.
- Gently tug on the wires to ensure they’re firmly attached.
Avoid over-tightening, as this can damage the wires or terminals.
Tuck Wires Neatly
Once connected, carefully tuck the excess wire back into the wall cavity. This prevents pinching and keeps the installation clean.
Step 6: Attach the Arlo Doorbell to the Mounting Plate
With the wires connected, it’s time to mount the doorbell.
Align the Doorbell with the Plate
Hold the Arlo doorbell so the slots on the back align with the tabs on the mounting plate.
Slide Down to Lock
Gently slide the doorbell downward until it clicks into place. You should feel it lock securely.
Secure with the Security Screw
Use the provided security screw and screwdriver to fasten the doorbell to the plate. This prevents tampering and ensures the unit stays in place.
Step 7: Turn the Power Back On
Now that everything is connected and mounted, it’s safe to restore power.
Flip the Breaker Back On
Go to your electrical panel and switch the doorbell breaker back to the “on” position.
Wait for the Doorbell to Power Up
The Arlo doorbell will take a few seconds to initialize. You’ll see lights on the front—usually a blinking blue or white light—indicating it’s powering up and connecting to Wi-Fi.
Step 8: Set Up the Arlo Doorbell in the App
The final step is configuring your doorbell using the Arlo app.
Open the Arlo App
Launch the Arlo app on your smartphone or tablet. Make sure you’re logged into your Arlo account.
Tap “Add Device”
In the app, tap the “+” or “Add Device” button. Select “Doorbell” and then “Wired Doorbell.”
Follow the On-Screen Instructions
The app will guide you through the setup process:
- Scan the QR code on the back of the doorbell or enter the serial number manually.
- Connect the doorbell to your Wi-Fi network. Make sure you select the 2.4 GHz band (not 5 GHz).
- Name your doorbell (e.g., “Front Door”).
- Set up motion zones and alert preferences.
Test the Doorbell
Once setup is complete, test the doorbell by pressing the button. You should see live video in the app, hear audio, and receive a notification.
Also, test the chime inside your home to ensure it rings when the button is pressed.
