Pro tip: Buy a few extra feet of wire—better to have too much than too little. Also, check local building codes. Some areas require permits for electrical work, even low-voltage installations.
Step 1: Choose the Right Transformer
The heart of your hardwired setup is the transformer. It converts your home’s standard 120V AC power into the low-voltage power (16-24V AC) that the Ring Doorbell Pro needs. Without a proper transformer, your doorbell won’t get enough power to function reliably.
Why Voltage Matters
The Ring Doorbell Pro requires a steady 16-24V AC power supply. Too little voltage, and the doorbell may not charge or operate correctly. Too much, and you risk damaging the device. Most standard doorbell transformers output 16V or 24V, which is perfect.
Check Your Current Setup (If Any)
Even if you don’t have a doorbell, you might have a transformer already installed—perhaps in your basement, attic, or near your electrical panel. Look for a small metal box with wires coming out. Use a voltage tester to check if it’s live and what voltage it outputs.
If you find one, great! Test it with a multimeter. Set the multimeter to AC voltage and touch the probes to the transformer’s output terminals. If it reads between 16V and 24V, you’re good to go. If it’s below 16V or above 24V, replace it.
Buying a New Transformer
If there’s no existing transformer or yours is incompatible, buy a new one. Here’s what to look for:
- Voltage: 16V or 24V AC.
- Wattage (VA): 30-40VA is ideal. This provides enough power for the Ring Doorbell Pro and any future smart doorbell features.
- Compatibility: Ring recommends their official transformer, but most standard doorbell transformers work.
Popular options include:
- Ring Transformer (16V, 30VA)
- Hampton Bay Doorbell Transformer (16V, 30VA)
- Heath Zenith Transformer (24V, 40VA)
Install the transformer near your electrical panel or in a junction box. It should be accessible and protected from moisture. Follow the manufacturer’s instructions for mounting and wiring.
Step 2: Plan Your Wire Route
Now that you have power sorted, it’s time to run wire from the transformer to your doorbell location. This is the trickiest part—especially without an existing wire path—but with careful planning, it’s totally doable.
Choose the Best Path
Look for the shortest, safest route from the transformer to your front door. Common paths include:
- Through the attic or basement.
- Along baseboards or under trim.
- Inside walls (requires drilling).
- Exterior raceway (for a clean look).
Avoid running wire near high-voltage lines, water pipes, or heat sources. Keep it at least 6 inches away from electrical wires to prevent interference.
Measure and Cut the Wire
Use a tape measure to determine the distance. Add 10-15% extra for slack and routing around corners. Cut two lengths of 18-22 gauge doorbell wire (one for each terminal).
Drill Holes for Wire Access
You’ll need to get the wire from inside your home to the exterior mounting spot. Here’s how:
- Drill a small hole (¼ to ½ inch) through the wall near the doorframe.
- Use a drill bit slightly larger than the wire diameter.
- Angle the drill slightly downward to prevent water from entering.
- Insert a fish tape or flexible rod to guide the wire through.
If drilling through brick or concrete, use a masonry bit and anchor the hole with silicone sealant to prevent moisture.
Run the Wire
Feed one end of the wire from the transformer location to the doorbell spot. Use wire staples or clips to secure it along the route. If running externally, use a weatherproof raceway to protect the wire and keep it tidy.
Pro tip: Label both ends of the wire (e.g., “Transformer” and “Doorbell”) to avoid confusion later.
Step 3: Connect the Transformer
With the wire in place, it’s time to connect everything to the transformer. Safety first—always turn off power at the breaker before working with electrical components.
Turn Off Power
Go to your electrical panel and shut off the breaker that controls the circuit you’re working on. Use a voltage tester to confirm the power is off at the transformer location.
Wire the Transformer to the Panel
Most transformers connect directly to a 120V circuit. Here’s how:
- Remove the cover of the electrical junction box where the transformer will go.
- Connect the black (hot) wire from the transformer to the hot wire in the box using a wire nut.
- Connect the white (neutral) wire to the neutral wire.
- Connect the green or bare copper ground wire to the ground.
- Secure all connections with electrical tape.
Mount the transformer inside the junction box or on a nearby surface. Ensure it’s secure and won’t vibrate or loosen over time.
Connect the Low-Voltage Wires
Now connect the two low-voltage wires (from your doorbell run) to the transformer’s output terminals. These are usually labeled “Common” and “Front” or just two screw terminals.
- Strip about ½ inch of insulation from each wire.
- Loosen the terminal screws.
- Wrap the bare wire around the screw in a clockwise direction.
- Tighten the screw to secure the connection.
Double-check that the wires are firmly attached and not touching each other.
Turn Power Back On and Test
Restore power at the breaker. Use a multimeter to test the voltage at the doorbell end of the wire. You should see 16-24V AC. If not, check your connections and transformer output.
Step 4: Mount the Ring Doorbell Pro
With power confirmed, it’s time to install the doorbell itself. Proper mounting ensures clear video, accurate motion detection, and a professional look.
Choose the Mounting Location
The ideal spot is:
- About 4 feet above the ground.
- Centered on the doorframe or wall.
- Facing the approach path (not blocked by plants or decorations).
- Within Wi-Fi range (test signal strength with your phone).
Avoid mounting in direct sunlight or near heat sources, as this can affect performance.
Mark and Drill Mounting Holes
Hold the mounting bracket against the wall. Use a level to ensure it’s straight. Mark the screw holes with a pencil. Drill pilot holes using a drill bit slightly smaller than the screws.
If mounting on brick or concrete, use masonry anchors. For wood or vinyl, standard screws work fine.
Connect the Wires
Before securing the bracket, connect the low-voltage wires:
- Strip ½ inch of insulation from each wire.
- Insert the wires into the back of the Ring Doorbell Pro (they’re labeled “Front” and “Transformer”).
- Push the doorbell onto the mounting bracket until it clicks into place.
The Ring Doorbell Pro uses a simple push-in connector—no screws needed. Just make sure the wires are fully inserted.
Secure the Doorbell
Once connected, press the doorbell firmly onto the bracket. It should snap in securely. Use the included security screw to prevent tampering.
Step 5: Complete Setup in the Ring App
Now that your doorbell is powered and mounted, it’s time to finish the setup using the Ring app.
Download and Open the Ring App
Available on iOS and Android, the Ring app guides you through setup, customization, and monitoring.
Add Your Device
- Tap “Set Up a Device” and select “Doorbells.”
- Choose “Ring Doorbell Pro.”
- Scan the QR code on the back of the device or enter the serial number manually.
Connect to Wi-Fi
Follow the prompts to connect your doorbell to your home Wi-Fi network. Use a 2.4GHz network for best compatibility (5GHz may not work reliably).
Test Power and Video
The app will check if the doorbell is receiving power. If it says “Hardwired,” you’re good to go. Test the live view to ensure the camera is working and the image is clear.
Customize Settings
Adjust motion zones, notification preferences, and recording settings. You can also set up linked devices, like Ring Chimes or Alexa-enabled speakers.
