Pro tip: Take a photo of your current doorbell wiring before disconnecting anything. This helps you remember how wires were connected.
Step 1: Turn Off the Power
Safety first! Working with live electricity is dangerous. Even low-voltage doorbell circuits can cause shocks or damage your new device.
Locate Your Breaker Box
Go to your home’s main electrical panel. Look for a breaker labeled “doorbell,” “chime,” or “low voltage.” If there’s no label, you may need to test breakers one by one.
Turn Off the Correct Breaker
Switch off the breaker that controls your doorbell. To confirm it’s off, press your existing doorbell button. If the chime doesn’t sound, power is off.
Double-Check with a Voltage Tester
Use a non-contact voltage tester near the doorbell wires. Touch the tip to the wire terminals. If the tester doesn’t light up or beep, power is off. If it does, turn off additional breakers until it’s safe.
Never skip this step. Even if the chime didn’t ring, residual voltage could still be present.
Step 2: Remove the Old Doorbell
Now that power is off, it’s time to remove the 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.
Disconnect the Wires
You’ll see two small wires connected to terminals (usually labeled “Front” and “Trans”). Loosen the screws and carefully pull the wires free. Don’t let them fall back into the wall.
Cap the Wires Temporarily
Twist wire nuts onto the exposed ends to prevent accidental contact. This keeps them safe while you work.
Remove the Mounting Bracket (if needed)
Some old doorbells have a separate bracket. Unscrew it if your new doorbell uses a different mounting system.
Tip: If the wires are too short, you may need to extend them later. Keep this in mind during installation.
Step 3: Check Doorbell Compatibility
Not all homes are ready for a wired video doorbell. You need the right voltage and wiring.
Test the Transformer Voltage
Your doorbell transformer converts household voltage (120V) to low voltage (16–24V AC). Most video doorbells require at least 16V and 10–40VA (volt-amperes).
Use a multimeter to test the voltage:
- Set the multimeter to AC voltage (V~).
- Touch the probes to the two doorbell wires.
- Read the voltage. If it’s below 16V, your transformer may be too weak.
If voltage is low, you may need to upgrade the transformer or use a plug-in power adapter (some brands offer these).
Check Wire Condition
Inspect the wires for fraying, corrosion, or damage. Replace damaged wires before installing the new doorbell.
Verify Wi-Fi Signal
Your video doorbell needs a strong Wi-Fi connection. Use your phone to check signal strength at the door. If it’s weak, consider a Wi-Fi extender.
Step 4: Install the Mounting Bracket
The mounting bracket holds your doorbell securely. Proper installation ensures it stays level and aligned.
Use the Installation Template
Most doorbell kits include a paper template. Tape it to the wall where you want the doorbell. Make sure it’s level using a bubble level.
Mark Drill Points
Use a pencil to mark the screw holes through the template. Remove the template.
Drill Pilot Holes
Drill small pilot holes at the marked spots. This prevents wood or siding from splitting.
Secure the Bracket
Align the bracket with the holes and screw it into place. Don’t overtighten—this can crack the bracket or wall.
Tip: If mounting on brick or concrete, use wall anchors and a masonry drill bit.
Step 5: Connect the Wires
Now it’s time to connect your doorbell to the home’s wiring.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch of insulation from each wire. Expose clean copper.
Attach Wires to the Bracket
Some brackets have built-in terminals. Loosen the screws, insert the wires, and tighten. Others require you to connect wires directly to the doorbell.
Use Wire Nuts (if needed)
If your doorbell doesn’t have screw terminals, twist the wires together and secure with a wire nut. Wrap with electrical tape for extra safety.
Secure Loose Wires
Tuck any excess wire into the wall cavity. Don’t let wires hang loose—they can get damaged or cause shorts.
Pro tip: Label wires “Front” and “Trans” with tape if you’re unsure which is which. Most doorbells aren’t polarity-sensitive, but labeling helps.
Step 6: Attach the Video Doorbell
With the bracket and wires ready, mount the doorbell.
Align the Doorbell
Slide the doorbell onto the bracket. Most models click into place or use screws.
Secure with Screws
Use the provided security screws to lock the doorbell in place. These prevent theft—most kits include a special screwdriver.
Check Alignment
Step back and make sure the doorbell is level and centered. Adjust if needed.
Step 7: Restore Power and Test
You’re almost done! Now it’s time to power up and test.
Turn the Breaker Back On
Go to the breaker box and switch the doorbell circuit back on.
Wait for the Doorbell to Power Up
Most video doorbells take 30–60 seconds to boot. Look for LED lights or sounds indicating power.
Download the App
Install the manufacturer’s app (e.g., Ring, Nest, Arlo) on your phone. Create an account if needed.
Follow Setup Instructions
The app will guide you through Wi-Fi setup, naming your doorbell, and adjusting settings. Make sure your phone is connected to the same Wi-Fi network.
Test the Doorbell
Press the button. Check if:
- The chime rings (if connected).
- You receive a notification on your phone.
- Live video streams clearly.
- Two-way audio works.
If everything works, you’re all set!
