Before diving into the installation, gather all the tools and materials. Having everything ready will save time and reduce frustration.
Tools and Materials
- Arlo Video Doorbell (wired or wire-free model)
- Smartphone with the Arlo app installed (iOS or Android)
- Screwdriver (usually Phillips #2)
- Drill and drill bits (if mounting on brick, stucco, or concrete)
- Level (to ensure the doorbell is straight)
- Pencil (for marking drill holes)
- Voltage tester (optional but recommended)
- Wire strippers (if you need to trim or re-strip wires)
- Electrical tape
- Wire nuts (usually included with the Arlo kit)
- Optional: Arlo Chime or compatible mechanical/digital chime
Check Your Existing Doorbell System
Not all homes are ready for a smart doorbell. Arlo doorbells require a few key components to work properly:
– Existing doorbell wiring: You need two low-voltage wires (usually labeled “front” and “transformer”) connected to your current doorbell button.
– Transformer voltage: Arlo recommends a transformer that outputs 16–24 volts AC. Most older homes have 8–16V transformers, which may not be enough. Use a multimeter or voltage tester to check.
– Chime compatibility: If you have a mechanical chime (the classic “ding-dong” type), it should work. Digital chimes may require a resistor or Arlo Chime.
If your transformer is below 16V, you may need to upgrade it or use the Arlo wire-free model (which runs on a rechargeable battery). For most wired installations, we recommend sticking with the wired version for reliable power.
Step 1: Turn Off the Power
Safety first! Working with electrical wires can be dangerous if the power is still on.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “doorbell,” “chime,” or “front door.” If there’s no label, turn off the main breaker to be safe.
Test the Power
Use a non-contact voltage tester near the doorbell button. Press the button—if the tester beeps or lights up, the power is still on. Double-check your breaker and turn it off again.
Pro Tip: Take a photo of your breaker panel before turning anything off. This helps you remember which breaker controls the doorbell.
Step 2: Remove Your Old Doorbell
Now that the power is off, it’s time to remove the existing doorbell button.
Unscrew the Old Button
Use your screwdriver to remove the two screws holding the doorbell button to the wall. Gently pull the button away from the wall—you should see two wires connected to the back.
Disconnect the Wires
Loosen the terminal screws or pull the wires out of the back (depending on your model). Be careful not to let the wires slip back into the wall. If they do, you may need to fish them out with needle-nose pliers.
Pro Tip: Twist the exposed wire ends slightly to keep them from fraying. You can also wrap them with electrical tape temporarily to prevent short circuits.
Step 3: Prepare the Arlo Doorbell
Now it’s time to get your Arlo doorbell ready for installation.
Unbox and Inspect
Open the Arlo package and make sure you have:
– The Arlo Video Doorbell unit
– Mounting plate
– Screws and anchors
– Wire nuts
– Optional: Anti-theft screw and tool
Attach the Mounting Plate
The mounting plate is the bracket that holds the doorbell to the wall. It has two keyholes for screws and a slot for the wires.
– Hold the plate 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.
Pro Tip: The ideal height for a doorbell is 48–52 inches from the ground. This ensures clear video of visitors and reduces glare from the sun.
Step 4: Drill and Mount the Plate
If you’re mounting on wood or siding, you may not need to drill. But for brick, stucco, or concrete, drilling is necessary.
Drill Pilot Holes
Use a drill bit slightly smaller than your wall anchors. Drill into the marked spots, about 1–1.5 inches deep.
Insert Anchors
Tap the plastic wall anchors into the holes with a hammer. These provide a secure base for the screws.
Secure the Mounting Plate
Line up the plate with the anchors and screw it into place using the provided screws. Make sure it’s tight and level.
Step 5: Connect the Wires
This is the most critical step—connecting the wires correctly ensures your doorbell gets power.
Strip the Wire Ends (If Needed)
If the wire ends are frayed or too short, use wire strippers to expose about 1/4 inch of copper.
Connect to the Arlo Doorbell
The Arlo doorbell has two terminals: “Front” and “Trans.” It doesn’t matter which wire goes where—Arlo is non-polarized.
– Loosen the terminal screws on the back of the doorbell.
– Insert one wire into each terminal.
– Tighten the screws securely.
Pro Tip: If the wires are too short, use the included wire nuts to extend them with spare low-voltage wire.
Tuck Wires Neatly
Gently push the wires back into the wall cavity. Don’t force them—this prevents damage and ensures a clean install.
Step 6: Attach the Arlo Doorbell
Now it’s time to snap the doorbell onto the mounting plate.
Align and Secure
Hold the Arlo doorbell at an angle and slide it onto the mounting plate. Push it down until it clicks into place.
Use the Anti-Theft Screw (Optional)
For added security, insert the anti-theft screw into the bottom of the doorbell and tighten it with the included tool. This prevents thieves from easily removing the device.
Step 7: Turn the Power Back On
Once everything is connected, restore power to test the installation.
Flip the Breaker
Go back to your electrical panel and turn the doorbell breaker back on.
Wait for the Doorbell to Power Up
The Arlo doorbell will take 30–60 seconds to boot up. You’ll see a light on the front—usually blinking blue or white.
Pro Tip: If the light doesn’t come on, double-check your wiring and breaker. The doorbell won’t work without power.
Step 8: Set Up the Arlo App
The Arlo app is your control center for the doorbell. It handles Wi-Fi setup, notifications, and settings.
Download and Open the App
If you haven’t already, download the “Arlo” app from the App Store or Google Play. Create an account or log in.
Add a New Device
Tap the “+” icon and select “Video Doorbell.” Follow the on-screen prompts.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the doorbell or in the app. This pairs the device with your account.
Connect to Wi-Fi
Choose your home Wi-Fi network and enter the password. Arlo doorbells require a 2.4 GHz network (not 5 GHz).
Pro Tip: Place your phone close to the doorbell during setup to ensure a strong signal.
Complete the Setup
The app will guide you through:
– Naming your doorbell (e.g., “Front Door”)
– Setting motion zones
– Enabling notifications
– Testing two-way audio
Step 9: Test and Adjust
Before you call the job done, test everything to make sure it works.
Test the Video
Open the Arlo app and view the live feed. Check for clarity, brightness, and field of view.
Test Motion Detection
Walk in front of the doorbell to trigger motion alerts. Adjust the sensitivity in the app if it’s too sensitive or not sensitive enough.
Test Two-Way Audio
Press the talk button in the app and speak. Ask someone to listen at the doorbell. Adjust volume if needed.
Test the Chime
Press the doorbell button. Your indoor chime should ring. If not, check compatibility or consider adding an Arlo Chime.
