Or maybe you just want a cleaner, more reliable setup. The good news? You can hardwire your Ring Doorbell using your existing doorbell wiring and skip the battery hassle for good.
In this guide, we’ll walk you through the entire process—from checking your current doorbell system to mounting your Ring Doorbell and testing it. Whether you’re a DIY beginner or a seasoned home improver, this step-by-step tutorial will help you get your smart doorbell powered up and working smoothly.
By the end, you’ll have a hardwired Ring Doorbell that stays charged, connects reliably to your Wi-Fi, and gives you peace of mind every time someone approaches your door.
Why Hardwire Your Ring Doorbell?
Before we dive into the steps, let’s talk about why hardwiring is worth it.
Most Ring Doorbells come with rechargeable batteries, which is great for flexibility. But if you live in a busy household, get lots of visitors, or use motion alerts frequently, the battery can drain fast—sometimes in just a few weeks.
Hardwiring solves that. It gives your doorbell a constant power source, so you never have to worry about it dying at the worst moment. Plus, hardwired models often perform better because they don’t rely on battery-saving modes.
Another benefit? Better Wi-Fi connectivity. Some hardwired Ring models, like the Ring Doorbell Pro, support advanced features like pre-roll video and dual-band Wi-Fi—features that aren’t available on battery-only versions.
And let’s not forget aesthetics. Without a battery compartment sticking out, your doorbell looks sleeker and more integrated with your home’s exterior.
What You’ll Need
Before you start, gather these tools and materials:
- Your Ring Doorbell (compatible with hardwiring—most models are)
- Screwdriver (Phillips head)
- Voltage tester or multimeter
- Wire strippers (if wires need trimming)
- Electrical tape
- Optional: Ring Chime Pro (if your existing chime isn’t compatible)
- Optional: Drill and wall anchors (if mounting on brick or stucco)
Most of these are basic household tools. If you don’t have a multimeter, you can pick one up at any hardware store for under $20.
Step 1: Turn Off the Power
Safety first! Even though doorbell systems use low voltage, it’s still electricity—and you don’t want to risk a shock.
Locate Your Doorbell Transformer
The transformer is the device that steps down your home’s 120V power to the 8–24V needed for your doorbell. It’s usually found in one of these places:
- Near your electrical panel (breaker box)
- In the basement or crawl space
- Inside a closet near the front door
- Behind the existing doorbell chime inside your home
Look for a small metal box with wires coming out of it. It often has “16V” or “24V” printed on it.
Turn Off the Circuit Breaker
Once you find the transformer, trace the wire back to your breaker panel. Turn off the breaker that controls the doorbell circuit. If you’re not sure which one it is, turn off the main breaker to be safe.
Test the Wires
Use a non-contact voltage tester or multimeter to confirm the power is off. Touch the tester to the doorbell wires at the front door. If it beeps or lights up, the power is still on—double-check your breaker.
This step is crucial. Don’t skip it.
Step 2: Remove Your Old Doorbell
Now that the power is off, it’s time to remove your existing doorbell button.
Unscrew the Faceplate
Use your screwdriver to remove the screws holding the old doorbell button to the wall. Gently pull the button away from the wall.
Disconnect the Wires
You’ll see two wires connected to the back of the button—usually black and white, but color doesn’t matter here. Loosen the terminal screws and pull the wires free.
Tape the Wires
To prevent them from slipping back into the wall, twist the exposed ends together and wrap them with electrical tape. This keeps them secure while you work.
Step 3: Check Your Doorbell Voltage
Not all doorbell systems are compatible with Ring Doorbells. You need to make sure your wiring provides the right voltage.
Use a Multimeter
Set your multimeter to measure AC voltage (usually marked with a “V~” symbol). Touch the red and black probes to the two doorbell wires.
Read the Voltage
A reading between 8V and 24V AC is ideal. If it’s below 8V, your Ring Doorbell may not get enough power. If it’s above 24V, it could damage the device.
Most homes have 16V or 24V systems, which work perfectly. If your voltage is too low, you may need to upgrade your transformer—something an electrician can help with.
What If Voltage Is Too Low?
If your system is under 8V, consider installing a Ring Chime Pro. It plugs into a wall outlet and boosts power to your doorbell. It also acts as a Wi-Fi extender, improving connectivity.
Alternatively, you can replace your transformer with a higher-voltage one (like 24V), but this requires electrical work and should be done by a professional.
Step 4: Prepare the Wires
Now that you’ve confirmed the voltage is good, it’s time to prep the wires for your Ring Doorbell.
Strip the Wire Ends
If the wire ends are frayed or too short, use wire strippers to remove about 1/4 inch of insulation. You want clean, exposed copper to make a solid connection.
Twist the Strands
If the wires are stranded (made of many thin wires), twist them gently to keep them together. This helps them stay in place when connected.
Keep Wires Separate
Don’t let the two wires touch each other. Keep them apart until you’re ready to connect them to the Ring Doorbell.
Step 5: Mount the Ring Doorbell Bracket
The Ring Doorbell comes with a mounting bracket that holds the device in place. You’ll attach this first.
Choose the Right Bracket
Ring includes different bracket angles (0°, 10°, 30°) to help you position the doorbell correctly. If your door is set back or you want a better view of the walkway, use a angled bracket.
Hold the Bracket in Place
Hold the bracket against the wall where you want to install the doorbell. Make sure it’s level and covers the existing screw holes (if possible).
Mark the Screw Holes
Use a pencil to mark where the screws will go. If the new holes don’t align with the old ones, you may need to drill new ones.
Drill and Secure
If you’re drilling into wood, you can screw directly into the wall. For brick, stucco, or concrete, use a drill with a masonry bit and wall anchors.
Screw the bracket into place using the provided screws. Make sure it’s tight and secure—your doorbell will be hanging from it.
Step 6: Connect the Wires to the Ring Doorbell
Now for the fun part—wiring your Ring Doorbell.
Thread the Wires Through the Bracket
Feed the two doorbell wires through the hole in the mounting bracket.
Attach the Wires to the Terminals
On the back of the Ring Doorbell, you’ll see two terminal screws labeled “Front” and “Trans.” It doesn’t matter which wire goes where—just connect one wire to each terminal.
Loosen the screws, insert the wire, and tighten the screw to secure it. Give the wire a gentle tug to make sure it’s snug.
Double-Check Connections
Make sure the wires are firmly attached and not touching each other. Loose connections can cause power issues or short circuits.
Step 7: Attach the Ring Doorbell to the Bracket
With the wires connected, it’s time to mount the doorbell.
Align the Doorbell
Slide the Ring Doorbell onto the bracket. It should click into place.
Secure with the Security Screw
Use the small security screw (included) to lock the doorbell to the bracket. This prevents theft—someone can’t just pull it off the wall.
Don’t Overtighten
Tighten the screw just enough to hold the doorbell. Overtightening can crack the plastic.
Step 8: Turn the Power Back On
Now that everything is connected, it’s time to restore power.
Go Back to the Breaker Panel
Turn the breaker back on. You should hear your indoor chime ring briefly—this means power is restored.
Wait a Moment
Give the system 30–60 seconds to stabilize. The Ring Doorbell needs a moment to power up and connect to Wi-Fi.
Step 9: Set Up the Ring Doorbell in the App
Your doorbell is powered, but it’s not fully ready yet. You need to complete the setup in the Ring app.
Open the Ring App
Download the Ring app (iOS or Android) if you haven’t already. Log in or create an account.
Tap “Set Up a Device”
Select “Doorbells” and choose your model. The app will guide you through the process.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the doorbell or in the app.
Connect to Wi-Fi
Follow the prompts to connect your doorbell to your home Wi-Fi network. Make sure you’re on a 2.4GHz network—most Ring Doorbells don’t support 5GHz.
Test the Connection
The app will check the signal strength. If it’s weak, consider moving your router or using a Ring Chime Pro as a Wi-Fi extender.
Customize Settings
Set up motion zones, notification preferences, and recording options. You can also link your doorbell to Alexa or Google Assistant.
Step 10: Test the Doorbell
Before you call it a day, test everything to make sure it’s working.
Ring the Doorbell
Press the button on your Ring Doorbell. You should hear the chime inside your home (if you have one) and get a notification on your phone.
Check the Video Feed
Open the Ring app and view the live feed. Make sure the image is clear and the audio works.
Test Motion Alerts
Walk in front of the doorbell to trigger motion detection. You should get an alert within a few seconds.
Adjust Angle if Needed
If the view is too high or low, you can adjust the bracket angle or reposition the doorbell slightly.
