Before you begin, gather the following tools and materials to ensure a smooth installation:
- Your Arlo doorbell (wired model, such as Arlo Essential Wired Video Doorbell or Arlo Pro 4 Wired)
- The included mounting bracket and screws
- The Arlo power kit (included with most models)
- A Phillips-head screwdriver
- A drill (optional, for harder surfaces like brick or concrete)
- A voltage tester (recommended, to confirm power is off)
- Your smartphone with the Arlo app installed (available on iOS and Android)
- A stable Wi-Fi connection (2.4 GHz network required; 5 GHz not supported for initial setup)
It’s also helpful to have a helper nearby, especially if you’re working on a ladder or need a second pair of hands to hold the doorbell during mounting.
Step 1: Check Your Doorbell’s Compatibility
Not all homes are ready for a smart doorbell right out of the box. Before you start disassembling your old doorbell, it’s crucial to verify that your existing wiring and electrical system can support the Arlo doorbell.
Check Your Transformer Voltage
Arlo wired doorbells require a transformer that outputs between 16 and 24 volts AC. Most older homes have transformers in this range, but some very old or very new systems may fall outside it.
To check:
- Turn off power to your doorbell at the circuit breaker.
- Remove your existing doorbell button.
- Use a multimeter or voltage tester to measure the voltage across the two wires.
- If the reading is between 16V and 24V AC, you’re good to go. If it’s below 16V, your doorbell may not get enough power. If it’s above 24V, you risk damaging the device.
If your voltage is too low, you may need to upgrade your transformer. This is a job for a licensed electrician if you’re not comfortable working with electrical systems.
Ensure You Have Existing Wiring
Arlo wired doorbells require two wires (typically labeled “front” and “trans”) connected to your doorbell chime. If you only have one wire or no wires at all, you’ll need to run new wiring or consider a battery-powered model (though Arlo’s wired models are designed for continuous power).
Check Your Chime Type
Arlo doorbells work with most mechanical and digital chimes. However, some very old or proprietary chime systems may not be compatible. If your chime is more than 20 years old or made by a niche manufacturer, check Arlo’s compatibility list online before proceeding.
Step 2: Turn Off Power and Remove the Old Doorbell
Safety first! Always turn off the power before working with electrical components.
Turn Off the Circuit Breaker
Locate your home’s electrical panel and find the breaker that controls your doorbell. It’s often labeled “doorbell,” “chime,” or “front door.” Turn it off. To be extra safe, use a non-contact voltage tester near the doorbell wires to confirm no power is flowing.
Remove the Old Doorbell Button
Unscrew the old doorbell button from the wall. Gently pull it away to expose the two wires underneath. Loosen the terminal screws and disconnect the wires. Label them if needed (e.g., “front” and “trans”) so you know which is which later.
Inspect the Wires
Check the condition of the wires. If they’re frayed, corroded, or too short, you may need to strip back the insulation or extend them slightly. Clean any corrosion with a small wire brush or sandpaper.
Step 3: Install the Arlo Power Kit
One of the most important steps in how to hook up Arlo doorbell is installing the power kit. This small device ensures your doorbell gets stable power and enables advanced features like live streaming and motion detection.
Why the Power Kit Is Necessary
Unlike traditional doorbells that only draw power when the button is pressed, smart doorbells need constant power to stay connected to Wi-Fi and record video. The power kit bridges the gap between your chime and the doorbell, providing steady voltage without disrupting your existing chime.
How to Install the Power Kit
- Open your doorbell chime box (usually located in a closet, basement, or attic).
- Locate the two terminals where the doorbell wires connect (often labeled “Front” and “Trans”).
- Disconnect the wire from the “Front” terminal.
- Connect that wire to one of the terminals on the Arlo power kit.
- Take the included short wire (usually red) and connect one end to the other terminal on the power kit.
- Connect the other end of that wire to the “Front” terminal on the chime.
- Leave the “Trans” wire connected as it was.
- Secure the power kit inside the chime box using the included adhesive pad or screws.
The power kit should now be installed in parallel with your chime, allowing power to flow to the doorbell while still triggering the chime when pressed.
Test the Power Kit
Turn the power back on at the breaker. Press the doorbell button (even though it’s disconnected) to see if the chime still rings. If it does, the power kit is working correctly. If not, double-check your connections.
Step 4: Mount the Arlo Doorbell
Now it’s time to attach your new Arlo doorbell to the wall.
Choose the Right Location
Mount the doorbell at a height of 4 to 5 feet from the ground. This ensures it captures faces clearly and avoids being blocked by plants or mailboxes. Angle it slightly toward the walkway or driveway for better motion detection.
Avoid placing it in direct sunlight or near heat sources like vents, as this can affect video quality and sensor performance.
Attach the Mounting Bracket
- Hold the mounting bracket against the wall where you want to install the doorbell.
- Use a level to ensure it’s straight.
- Mark the screw holes with a pencil.
- Drill pilot holes if needed (especially for brick or concrete).
- Secure the bracket with the included screws.
Connect the Wires
Take the two doorbell wires and connect them to the terminals on the back of the Arlo doorbell. It doesn’t matter which wire goes where—Arlo doorbells are polarity-independent.
Gently push the wires back into the wall and snap the doorbell onto the mounting bracket. You should hear a click when it’s secure.
Secure with the Anti-Theft Screw
Use the small security screw (included) to lock the doorbell in place. This prevents someone from easily removing it from the wall.
Step 5: Set Up the Arlo Doorbell in the App
Now that the hardware is installed, it’s time to configure your doorbell using the Arlo app.
Download and Open the Arlo App
If you haven’t already, download the Arlo app from the Apple App Store or Google Play Store. Create an account or log in if you already have one.
Add a New Device
- Tap the “+” icon or “Add Device” button.
- Select “Video Doorbell” from the list.
- Choose your specific model (e.g., Arlo Essential Wired).
- The app will prompt you to scan the QR code on the back of the doorbell or enter the serial number manually.
Connect to Wi-Fi
The app will guide you through connecting the doorbell to your home Wi-Fi network. Make sure you’re connected to a 2.4 GHz network—Arlo doorbells do not support 5 GHz during setup.
Enter your Wi-Fi password when prompted. The doorbell will attempt to connect. This may take a minute or two.
Sync the Doorbell
Once connected, the app will ask you to press and hold the doorbell button for 3–5 seconds until the LED light flashes. This syncs the device with your Arlo account.
