Choosing the Right Ring Doorbell Model
Not all Ring Doorbells work the same way. Some are battery-powered, while others require hardwiring. For integration with an intercom system, you’ll likely want a hardwired model.
The Ring Video Doorbell Wired and Ring Video Doorbell Pro 2 are excellent choices because they connect directly to your existing doorbell wiring and can integrate with intercom systems. These models support two-way audio, motion detection, and live view—all essential for intercom functionality.
Avoid battery-only models like the Ring Video Doorbell (2nd Gen) if you plan to use intercom features regularly. Battery-powered units may not provide consistent power for continuous audio communication.
Check Your Existing Doorbell and Intercom Setup
Before removing your old doorbell, inspect your current setup. Most homes with intercom systems have a doorbell transformer that supplies low-voltage power (usually 8–24 volts) to the doorbell and intercom unit.
Use a multimeter or voltage tester to check the voltage across the doorbell wires. Ring recommends a transformer with at least 16 volts and 20–30 VA (volt-amperes) for reliable performance. If your transformer is underpowered, your Ring Doorbell may not function properly or could cause flickering lights.
If your intercom system uses a separate power source or digital signaling (like some apartment intercoms), consult the manufacturer’s guide. Some systems may require a relay or adapter to work with Ring.
Step 1: Turn Off the Power
Safety first. Working with electrical wiring can be dangerous if you don’t take precautions.
Locate Your Circuit Breaker
Go to your home’s electrical panel (breaker box). Look for the circuit labeled “doorbell,” “chime,” or something similar. If you can’t find it, turn off the main breaker to be safe.
Test the Wires
After turning off the power, remove the old doorbell from the wall. Use a non-contact voltage tester to touch the exposed wires. If the tester lights up or beeps, the power is still on—double-check your breaker.
Once you confirm the wires are dead, you can safely proceed.
Step 2: Remove the Old Doorbell
Carefully unscrew the old doorbell from the wall. Gently pull it away to expose the two wires connected to the back.
Label the Wires
Use a small piece of tape to label the wires “Front” and “Trans” (transformer). This helps during reinstallation. If your intercom system has additional wires (like for a second button or indoor unit), label those too.
Disconnect the Wires
Loosen the terminal screws and remove the wires. Be careful not to let them fall back into the wall. If they do, you may need a fish tape or magnet to retrieve them.
Step 3: Prepare the Mounting Location
Now it’s time to get the wall ready for your new Ring Doorbell.
Check the Mounting Surface
Ring Doorbells can be mounted on wood, brick, stucco, or siding. If you’re drilling into brick or concrete, use a masonry drill bit and wall anchors for a secure fit.
Use the Ring Mounting Template
The Ring kit includes a paper template. Tape it to the wall at the desired height (typically 48 inches from the ground). Use a level to ensure it’s straight.
Mark the screw holes with a pencil. If you’re not using the included mount, you may need to drill pilot holes first.
Drill and Secure the Mount
Drill holes at the marked spots. Insert wall anchors if needed. Then, screw the mounting bracket into place using the provided screws. Make sure it’s tight and level.
Step 4: Connect the Wires to the Ring Doorbell
This is where your Ring Doorbell connects to your home’s wiring and intercom system.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch of insulation from each wire. This exposes fresh copper for a solid connection.
Attach Wires to the Ring Doorbell
The Ring Doorbell has two screw terminals: one for the “Front” wire and one for the “Trans” wire. Loosen the screws, insert the stripped wire ends, and tighten securely.
If your intercom system has additional wires (like for an indoor speaker or second button), you may need to connect them to a junction box or use wire nuts to cap them off. Consult your intercom manual for guidance.
Secure the Doorbell to the Mount
Slide the Ring Doorbell onto the mounting bracket until it clicks into place. Use the included security screw to prevent tampering.
Step 5: Power Up and Test the Connection
Now that everything is wired, it’s time to restore power and test the system.
Turn the Power Back On
Go back to your breaker box and flip the doorbell circuit back on. The Ring Doorbell should light up, indicating it’s receiving power.
Check for Power Issues
If the light doesn’t come on, double-check your wiring and breaker. A loose connection or underpowered transformer could be the issue.
If your lights flicker when the doorbell rings, your transformer may be too weak. Consider upgrading to a 16V, 30VA transformer.
Step 6: Set Up the Ring App
The Ring app is your control center. It guides you through setup and lets you customize settings.
Download and Open the Ring App
Available on iOS and Android, the Ring app is free. Create an account or log in if you already have one.
Add a New Device
Tap the menu (three lines) and select “Set up a device.” Choose “Doorbells” and follow the prompts.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of your Ring Doorbell. This pairs the device with your account.
Connect to Wi-Fi
Select your home Wi-Fi network and enter the password. Ring recommends 2.4 GHz for better range and reliability. If you only have 5 GHz, the app will warn you—some older models don’t support it.
Name Your Doorbell
Give your doorbell a name like “Front Door” or “Main Entrance.” This helps if you have multiple Ring devices.
Adjust Settings
Customize motion zones, notification preferences, and video quality. Enable “Two-Way Talk” so you can speak through the intercom.
Step 7: Integrate with Your Intercom System
This is the key step—making your Ring Doorbell work with your existing intercom.
Test Two-Way Audio
Have someone press the doorbell button. Use the Ring app to answer and speak. You should hear audio through both the Ring speaker and your indoor intercom unit.
If you only hear audio through one device, check your wiring. The intercom may need to be connected in parallel with the doorbell.
Sync with Indoor Intercom Units
Some intercom systems have indoor panels with microphones and speakers. If yours does, ensure the wiring allows audio to pass through both the Ring and the intercom.
If your intercom uses a different protocol (like SIP or proprietary digital signals), you may need a bridge device or consult a professional installer.
Use Ring Chime for Enhanced Alerts
If your intercom doesn’t provide loud enough alerts, consider adding a Ring Chime or Chime Pro. It plugs into a wall outlet and plays customizable sounds when the doorbell is pressed.
Step 8: Fine-Tune and Optimize
Once everything is working, take time to optimize your setup.
Adjust the Angle
Tilt the Ring Doorbell slightly downward to capture visitors’ faces. Avoid pointing it directly at the sun to prevent glare.
Set Motion Zones
In the app, draw motion zones to focus on your walkway and ignore busy streets or trees. This reduces false alerts.
Enable Privacy Zones
If your camera sees a neighbor’s yard or a busy sidewalk, use privacy zones to block those areas from recording.
Update Firmware
Ring regularly releases updates. Go to Device Health in the app and check for updates. Updated firmware improves performance and security.
Troubleshooting Common Issues
Even with careful installation, problems can arise. Here’s how to fix the most common ones.
Doorbell Not Powering On
- Check the breaker and wiring connections.
- Test the transformer voltage—should be at least 16V.
- Try a different power source or use a Ring Chime Pro for power boosting.
