- Wall anchors (for drywall or masonry)
- Mounting wedge (included with Ring Doorbell 2 for angle adjustment)
Step 1: Check Your Existing Doorbell System
Before you remove anything, inspect your current doorbell setup. Most homes built after the 1960s have a low-voltage doorbell system with wires running from a transformer (usually near your furnace or breaker panel) to the doorbell button and indoor chime.
Locate the Doorbell Transformer
The transformer steps down your home’s 120V power to 8–24V AC, which is safe for doorbells. It’s often tucked away in a basement, garage, or utility closet. Look for a small metal box with wires coming out—sometimes labeled “doorbell” or “chime.”
Test the Voltage
Use a multimeter or voltage tester to check the voltage at the doorbell button. Set your multimeter to AC voltage (V~) and touch the probes to the two wires. You should see between 8 and 24 volts. If it’s below 8V, your transformer may be too weak, and you’ll need to upgrade it (more on that later).
Pro Tip: If you don’t have an existing doorbell, you’ll need to install a transformer and run wires from your electrical panel to the door. This is more advanced and may require an electrician.
Check Wire Condition
Inspect the wires at the doorbell location. Are they frayed, corroded, or too short? If so, you may need to extend them or replace them. Ring recommends using 18- or 20-gauge doorbell wire.
Step 2: Turn Off the Power
Safety first! Even though doorbell systems use low voltage, it’s still important to turn off the power to avoid accidental shocks or short circuits.
Find the Right Circuit Breaker
Go to your main electrical panel and look for a breaker labeled “doorbell,” “chime,” or “low voltage.” If you can’t find it, turn off the breaker that controls your furnace or HVAC system—many transformers are connected there.
Test to Confirm Power Is Off
Use your voltage tester at the doorbell wires to double-check. If the tester doesn’t light up or beep, the power is off. If it does, turn off additional breakers until it’s safe.
Never skip this step. Even low-voltage systems can cause injury or damage your Ring device.
Step 3: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, carefully remove it.
Unscrew the Old Button
Use a screwdriver to remove the screws holding the old doorbell button to the wall. Gently pull it away to expose the wires.
Disconnect the Wires
Loosen the terminal screws and remove the wires. Don’t let them fall back into the wall—tape them to a pencil or stick to keep them accessible.
Inspect the Mounting Area
Check for damage, moisture, or rot. Clean the area and repair any issues before installing the Ring Doorbell 2.
Step 4: Prepare the Wires
Now it’s time to get your wires ready for the new doorbell.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch of insulation from each wire end. This exposes fresh copper for a solid connection.
Twist the Strands
If the wires are stranded (multiple thin wires), twist them gently to keep them together. This prevents fraying and ensures a clean connection.
Secure the Wires
Tape the wires to the wall or a nearby surface so they don’t slip back into the wall during installation.
Step 5: Mount the Ring Doorbell 2
Now comes the fun part—mounting your new smart doorbell.
Choose the Right Location
The ideal spot is about 4 feet above the ground, centered on the doorframe, and angled slightly toward the walkway. Avoid placing it too high or too low.
Use the Mounting Template
Ring includes a paper template in the box. Tape it to the wall where you want to install the doorbell. Use a level to make sure it’s straight.
Drill Pilot Holes
If mounting on wood, drill pilot holes for the screws. For brick, stucco, or concrete, use a masonry bit and wall anchors.
Attach the Mounting Plate
Line up the plate with the template and screw it into place. Don’t overtighten—this can crack the plastic.
Adjust the Angle (Optional)
If your doorbell isn’t facing the right direction, use the included mounting wedge. Attach it to the plate before mounting to tilt the camera slightly left, right, up, or down.
Step 6: Connect the Wires
This is the most critical step—making sure the wires are connected correctly.
Identify the Terminals
On the back of the Ring Doorbell 2, you’ll see two small terminals labeled “Front” and “Trans.” These connect to your doorbell wires.
Connect the Wires
Loosen the terminal screws, insert one wire into each terminal, and tighten the screws. It doesn’t matter which wire goes where—Ring devices are not polarity-sensitive.
Pro Tip: If your wires are too short, use wire nuts to extend them. Strip both ends, twist them together, and secure with a wire nut. Wrap with electrical tape for extra safety.
Secure the Wires
Tuck any excess wire neatly into the wall cavity to prevent damage.
Step 7: Attach the Ring Doorbell 2
With the wires connected, it’s time to mount the device.
Align the Device
Slide the Ring Doorbell 2 onto the mounting plate. It should click into place.
Secure with Screws
Use the included security screws and a screwdriver (or the provided screwdriver bit) to fasten the device. This prevents tampering.
Check the Fit
Make sure the doorbell is snug and level. Adjust if needed.
Step 8: Restore Power and Test
Now that everything is connected, it’s time to turn the power back on.
Turn On the Breaker
Go back to your electrical panel and flip the breaker back on.
Wait for the Light
The Ring Doorbell 2 has a small LED light on the front. When powered, it should glow solid blue for a few seconds, then turn off or pulse slowly.
Test the Doorbell
Press the button. You should hear a chime inside (if you have a wired chime) and see activity in the Ring app.
Step 9: Set Up the Ring App
The final step is configuring your doorbell through the Ring app.
Open the Ring App
Launch the app on your smartphone. If you don’t have an account, create one.
Add a New Device
Tap the menu (three lines), then “Set up a device,” and select “Doorbells.” Choose “Ring Video Doorbell 2.”
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the doorbell or inside the app.
Follow the On-Screen Instructions
The app will guide you through Wi-Fi setup, motion zones, notification preferences, and chime settings.
Test Live View
Tap “Live View” to see the camera feed. Speak through the app to test two-way audio.
