Before touching any wires or removing your doorbell, safety comes first. Electrical components can be dangerous if mishandled, so take these precautions seriously.
Turn Off the Power
The most important step is turning off power to your doorbell circuit at the main electrical breaker. Even though doorbells use low voltage (typically 8–24V), there’s still a risk of short circuits or shocks—especially if wires are frayed or exposed.
– Locate your home’s electrical panel.
– Find the breaker labeled “Doorbell,” “Front Door,” or similar. If unsure, turn off the breaker for the hallway or entryway lights—it’s often the same circuit.
– Flip the breaker to the OFF position.
– Test the existing doorbell button to confirm power is off (it shouldn’t ring).
Gather Your Tools
You’ll need just a few basic tools:
– Phillips-head screwdriver
– Voltage tester (optional but recommended)
– Small container for screws (so you don’t lose them)
– Ladder (if your doorbell is high up)
– Smartphone with the Arlo app installed and logged in
Check Your Equipment
Make sure you have:
– Your Arlo doorbell (fully charged if wire-free)
– The correct Arlo base station (matching your doorbell model)
– Original mounting plate and screws (or compatible replacements)
– Access to your home Wi-Fi network (2.4 GHz band required)
Pro tip: If your doorbell is wire-free, charge it fully before reinstalling. A low battery can cause sync failures even if the physical installation is perfect.
Step 1: Remove the Old or Loose Doorbell
If your doorbell is already partially detached or hanging loosely, start by removing it completely.
Detach the Doorbell from the Base
Most Arlo doorbells snap into a mounting base with a release tab or screw-lock mechanism.
– Look for a small release button or tab on the side or bottom of the doorbell.
– Press and hold the tab while gently pulling the doorbell away from the wall.
– If it’s secured with a screw (common on older models), use your Phillips screwdriver to loosen it slightly—don’t remove it fully yet.
Disconnect the Wires (If Wired)
If you have a wired Arlo doorbell (like the Arlo Pro 3 Wired Doorbell), you’ll see two thin wires connected to terminals on the back.
– Carefully unscrew the terminal screws and pull the wires free.
– Twist the wire ends slightly to keep them from fraying.
– Use electrical tape to cap each wire temporarily—this prevents accidental contact.
Note: Wire-free models (like the Arlo Essential) don’t have wires—they rely on rechargeable batteries and sync via the base station for charging and data.
Remove the Mounting Base (If Necessary)
If the base is damaged or you’re replacing it:
– Unscrew the base from the wall using your screwdriver.
– Gently pull it away, making sure not to damage the wires inside the wall.
Set the old base aside—you may need it for reference when installing the new one.
Step 2: Inspect and Prepare the Installation Area
Now that everything is removed, take a moment to inspect the setup.
Check Wire Condition
Look at the two doorbell wires coming out of the wall:
– Are they frayed, corroded, or broken? If yes, trim the ends with wire strippers and expose fresh copper.
– Are both wires intact and reaching the mounting area? If one is too short, you may need to gently pull more from the wall or consult an electrician.
Clean the Mounting Surface
Dust, paint, or old adhesive can prevent a secure fit.
– Wipe the wall area with a dry cloth.
– Remove any leftover tape or residue from the previous mount.
Verify Base Station Compatibility
Not all Arlo bases work with every doorbell. Double-check:
– Arlo Essential Doorbell → Works with Arlo Essential Base Station
– Arlo Pro 3 Doorbell → Works with Arlo SmartHub or Base Station (VMB4540, VMB5000, etc.)
– Arlo Video Doorbell (Wired) → Compatible with most Arlo hubs
Using the wrong base can cause pairing failures or charging issues.
Step 3: Install the Arlo Base Station
The base station is the bridge between your doorbell and your Wi-Fi network. It must be installed correctly for reliable performance.
Position the Base Correctly
– Mount the base at a height between 48–60 inches from the ground—standard doorbell height.
– Ensure it’s level using a spirit level or the leveling tool in the Arlo app (if available).
– Avoid placing it near metal surfaces, large appliances, or thick walls that block Wi-Fi signals.
Secure the Base to the Wall
– Hold the base against the wall and mark screw holes with a pencil.
– Drill pilot holes if needed (especially for brick or concrete).
– Insert wall anchors if mounting into drywall without studs.
– Screw the base firmly into place—don’t overtighten, as this can crack the plastic.
Connect the Wires (For Wired Models)
If you’re installing a wired doorbell:
– Feed the two doorbell wires through the center hole of the base.
– Loosen the terminal screws on the back of the base.
– Insert one wire into each terminal (polarity doesn’t matter for doorbells).
– Tighten the screws securely—wires should not wiggle loose.
For wire-free models: No wiring needed. The base acts as a charging dock and signal booster.
Step 4: Reinstall the Arlo Doorbell into the Base
This is the moment of truth—snapping your doorbell back into place.
Align the Doorbell with the Base
– Hold the doorbell so the charging contacts (small metal pins) align with the base.
– Make sure the doorbell is oriented correctly—the camera lens should face forward, not sideways.
Snap It Into Place
– Gently press the doorbell toward the base until you hear a firm “click.”
– Give it a light tug to confirm it’s secure—it shouldn’t come loose easily.
If it doesn’t click:
– Check for debris in the base or doorbell contacts.
– Ensure the mounting plate is flush with the wall.
– Try reseating the doorbell at a slight angle and pressing straight in.
Secure with Anti-Theft Screw (If Applicable)
Some Arlo models include a small security screw to prevent theft.
– Insert the screw into the designated hole on the side or bottom.
– Tighten gently with a screwdriver—don’t force it.
This extra step ensures your doorbell stays put, even in high-traffic areas.
Step 5: Restore Power and Test the Connection
Now it’s time to bring your system back to life.
Turn the Power Back On
– Return to your electrical panel.
– Flip the doorbell breaker back to the ON position.
– Wait 30–60 seconds for the system to power up.
Check for Lights on the Base
Most Arlo bases have LED indicators:
– Solid green: Good connection
– Blinking blue: Pairing mode
– Red or amber: Error or low signal
Refer to your model’s manual for exact light meanings.
Test the Doorbell Button
Press the doorbell button:
– You should hear a chime (if connected to a chime kit) or see a notification on your phone.
– If nothing happens, the doorbell may not be synced yet—proceed to the app setup.
Step 6: Reconnect via the Arlo App
Even if the doorbell is physically installed, it needs to reconnect to your Arlo account and Wi-Fi network.
Open the Arlo App
– Launch the Arlo app on your smartphone or tablet.
– Log in with your Arlo account credentials.
Put the Base in Pairing Mode
– On the base station, press and hold the SYNC button (usually on the side or back) for 3–5 seconds.
– The LED should blink blue, indicating it’s ready to pair.
Add the Doorbell in the App
– Tap the “+” icon or “Add Device” in the app.
– Select “Doorbell” from the device list.
– Follow the on-screen prompts:
– Confirm your Wi-Fi network (must be 2.4 GHz).
– Enter your Wi-Fi password.
– Wait for the app to detect the doorbell.
Complete the Setup
– The app will guide you through naming the doorbell (e.g., “Front Door”).
– Set up motion zones, alerts, and recording preferences.
– Once done, the doorbell should appear online in your device list.
Pro tip: If the app says “Device not found,” try moving closer to the base or restarting both the base and your phone.
Troubleshooting Common Reinstallation Issues
Even with careful steps, problems can arise. Here’s how to fix the most common ones.
