What You’ll Need Before You Begin

Before you touch a single wire, make sure you have all the necessary tools and materials. Rushing into installation without preparation can lead to frustration or even damage to your doorbell or electrical system.

Here’s a checklist of what you’ll need:

Ring Video Doorbell Pro – Make sure it’s the wired version, not the battery model.
Ring Pro Power Kit – This is included with the Ring Pro and is essential for proper operation.
Screwdriver set – A Phillips head screwdriver is usually sufficient.
Drill and drill bits – Only if you need to create new mounting holes.
Voltage tester – To confirm power is off and check wire voltage.
Wire strippers – In case you need to trim or re-strip wires.
Smartphone with Ring app installed – Available on iOS and Android.
Wi-Fi network – Ring Pro requires a 2.4 GHz or 5 GHz Wi-Fi connection.
Ladder – If your doorbell is mounted high, safety first!

Having these tools ready will save time and reduce stress during installation. Now, let’s move on to the first critical step: checking compatibility.

Step 1: Check Compatibility with Your Existing Doorbell

Not every wired doorbell is compatible with the Ring Pro. To avoid installation headaches, you need to verify that your current setup meets Ring’s power requirements.

Check Your Doorbell Transformer

The Ring Pro requires a transformer that outputs 16 to 24 volts AC and at least 30VA (volt-amperes). Most older doorbells use 8-16V transformers, which are too weak.

To check your transformer:

Locate your doorbell transformer. It’s usually found in your basement, garage, attic, or near your electrical panel.
Look for a small metal box with wires running to your doorbell and chime.
Check the label for voltage and VA ratings. If it says 16V or higher and 30VA or more, you’re good to go.

If your transformer is below 16V, you’ll need to upgrade it. Ring sells a compatible transformer, or you can purchase one from a hardware store. Installing a new transformer is a more advanced electrical task—consider hiring an electrician if you’re not comfortable.

Inspect Your Existing Wiring

Your doorbell should have two wires connected to the chime unit: one from the doorbell button and one from the transformer. These wires carry low voltage and are safe to handle—once the power is off.

Check that:

The wires are intact and not frayed.
There are at least two wires at the doorbell location (typically labeled “Front” and “Trans”).
The wires are long enough to reach the Ring Pro mounting plate (about 6–8 inches).

If your wiring is damaged or too short, you may need to extend it. Use 18- or 20-gauge doorbell wire, available at most hardware stores.

Test Your Doorbell Chime

The Ring Pro works with mechanical chimes (the traditional “ding-dong” type) and most digital chimes. However, some very old or proprietary chimes may not be compatible.

To test:

Press your current doorbell button.
Listen for a clear, consistent sound.
If the chime is silent, weak, or erratic, it may not work well with Ring Pro.

If your chime doesn’t work, you can still use the Ring Pro—it will send notifications to your phone—but you won’t hear a physical chime. Alternatively, you can install a Ring Chime or Chime Pro for indoor alerts.

Step 2: Turn Off Power and Remove Old Doorbell

Safety is paramount when working with electricity—even low-voltage systems. Always turn off power before handling wires.

Turn Off the Power

Go to your home’s main electrical panel (breaker box).
Locate the circuit breaker that controls your doorbell. It may be labeled “Doorbell,” “Chime,” or “Front Door.”
Switch the breaker to the OFF position.
Use a voltage tester at the doorbell wires to confirm no power is present. Touch one probe to each wire—if the tester doesn’t light up or beep, it’s safe to proceed.

Never assume the power is off just because the breaker is switched. Always test!

Remove the Old Doorbell Button

Unscrew the mounting screws on your existing doorbell button.
Gently pull the button away from the wall.
You’ll see two wires connected to terminals (usually labeled “Front” and “Trans”).
Loosen the terminal screws and carefully disconnect the wires.
Cap the wires with wire nuts or electrical tape to prevent them from touching each other or the wall.

Set the old doorbell aside. You won’t need it anymore.

Step 3: Install the Ring Pro Power Kit

The Ring Pro Power Kit is a small but critical component. It ensures your doorbell receives consistent power and prevents interference with your chime.

Locate Your Doorbell Chime

The chime is usually inside your front door, mounted on a wall. Open the chime cover to access the wiring.

Connect the Power Kit

Find the two wires connected to the “Front” terminal on the chime.
Disconnect these wires from the terminal.
Connect one wire to the “Front” terminal on the Ring Pro Power Kit.
Connect the other wire to the “Trans” terminal on the Power Kit.
Now, reconnect the two loose wires from the chime to the corresponding terminals on the Power Kit (usually labeled “Chime” and “Transformer”).
Secure all connections tightly and close the chime cover.

The Power Kit acts as a bridge, allowing the Ring Pro to draw power without disrupting the chime’s function. If you skip this step, your chime may not work or could buzz continuously.

Step 4: Mount the Ring Pro Doorbell

Now it’s time to install the Ring Pro at your door.

Prepare the Mounting Location

Hold the Ring Pro mounting plate against the wall where you want to install it.
Use a level to ensure it’s straight.
Mark the screw holes with a pencil.
If needed, drill pilot holes for the screws.

Connect the Wires

Take the two wires from your wall (the ones you disconnected earlier).
Strip about 1/4 inch of insulation from the ends if needed.
Insert one wire into the “Front” terminal on the mounting plate.
Insert the other wire into the “Trans” terminal.
Tighten the terminal screws to secure the wires.

Don’t worry about polarity—Ring Pro works with either wire in either terminal.

Attach the Mounting Plate

Align the mounting plate with the screw holes.
Secure it to the wall using the provided screws.
Make sure it’s snug and level.

Adjust the Angle (Optional)

If you want a better view of your porch, use the included wedge or corner kit:

Wedge Kit: Tilts the doorbell up to 30 degrees for a downward view.
Corner Kit: Mounts the doorbell at a 45-degree angle for side views.

Attach the wedge or corner piece to the mounting plate before securing it to the wall.

Step 5: Attach the Ring Pro and Secure It

Align the Ring Pro with the mounting plate.
Gently push it into place until it clicks.
Use the included security screw and screwdriver to secure the bottom of the doorbell.
This prevents theft and ensures a tight fit.

The Ring Pro should now be firmly mounted and connected.

Step 6: Turn Power Back On and Test

Go back to your breaker box and turn the doorbell circuit back ON.
Wait about 30 seconds for the Ring Pro to power up.
You should see a light on the front of the doorbell—usually a white or blue glow.

If the light doesn’t appear, double-check your wiring and power connections.

Test the Chime

Press the doorbell button. You should hear your indoor chime sound. If not, recheck the Power Kit installation.

Test the Doorbell Function

Open the Ring app on your phone and follow the setup prompts:

Tap “Set Up a Device” and select “Doorbells.”
Choose “Ring Video Doorbell Pro.”
Scan the QR code on the back of the doorbell or enter the serial number manually.
Follow the on-screen instructions to connect to Wi-Fi.
Name your doorbell (e.g., “Front Door”).
Adjust motion zones and notification settings.

Once connected, test the features:

Check live video feed.
Test two-way audio by speaking through the app.
Trigger motion detection by walking in front of the doorbell.
Press the button to simulate a visitor and confirm notifications.

Everything working? Great! Your Ring Pro is now fully installed.
