What You’ll Need
Before starting, gather all the tools and materials. Having everything ready will make the job smoother and safer.
Tools
- Screwdrivers (Phillips and flathead)
- Wire strippers
- Drill and drill bits (for mounting and running wires)
- Voltage tester (non-contact)
- Pliers
- Measuring tape
- Pencil or marker
- Electrical tape
Materials
- Ring doorbell (compatible model like Ring Video Doorbell Pro, Pro 2, or Wired)
- Doorbell transformer (16-24V AC, 20-30VA minimum)
- 18-22 gauge low-voltage wire (solid core, not stranded)
- Wire nuts or terminal blocks
- Mounting screws and anchors
- Electrical box or junction box (optional, for housing transformer)
- Conduit or wire molding (optional, for protecting wires)
Pro Tip: Buy a transformer with slightly higher VA (like 30VA) to ensure stable power, especially in cold weather or with long wire runs.
Step 1: Choose the Right Location
Start by deciding where to mount your Ring doorbell. The ideal spot is:
- At eye level (about 48 inches from the ground)
- Centered on the door or slightly offset if needed
- Close enough to a power source (like a nearby outlet or electrical box)
- Protected from direct rain and extreme weather
Use a measuring tape and pencil to mark the mounting area. Also, plan the wire path from the doorbell location to where you’ll install the transformer—usually near an electrical outlet or inside a basement, garage, or utility closet.
Check for Obstructions
Before drilling, check behind the wall for studs, pipes, or electrical wires. Use a stud finder to avoid damaging anything. If you’re running wires through walls, consider using a fish tape to guide the wire safely.
Step 2: Install the Transformer
The transformer is the heart of your hardwired setup. It converts 120V household current into the low-voltage power your Ring doorbell needs. Here’s how to install it safely.
Turn Off the Power
Go to your home’s electrical panel (breaker box) and turn off the power to the circuit you’ll be working on. Use a non-contact voltage tester to confirm the power is off before touching any wires.
Choose a Mounting Spot
Mount the transformer near an electrical outlet or inside a junction box. Common locations include:
- Inside a garage or basement near an outlet
- Inside an electrical box in a closet
- Near the main electrical panel (if space allows)
Make sure the transformer is accessible and protected from moisture and physical damage.
Wire the Transformer
Follow these steps:
- Remove the cover of the electrical box or outlet where you’ll install the transformer.
- Connect the transformer’s primary (input) wires to the 120V circuit:
- Black (hot) wire to the black (hot) wire in the box
- White (neutral) wire to the white (neutral) wire
- Green or bare (ground) wire to the ground wire or box
- Use wire nuts to secure each connection. Wrap with electrical tape for extra safety.
- Mount the transformer securely using screws.
- Run the low-voltage (secondary) wires from the transformer to the doorbell location. These are usually labeled “1” and “2” or “COM” and “T”.
Safety Note: If you’re not comfortable working with 120V wiring, hire a licensed electrician. Mistakes can cause shocks or fires.
Step 3: Run the Low-Voltage Wire
Now it’s time to connect the transformer to your doorbell using low-voltage wire. This wire carries the safe, reduced voltage from the transformer to the doorbell.
Choose the Right Wire
Use 18-22 gauge solid-core wire. Avoid stranded wire—it can fray and cause poor connections. You can buy pre-cut lengths or a spool for custom runs.
Plan the Wire Path
Decide how to route the wire from the transformer to the doorbell. Options include:
- Through the wall: Drill a small hole from inside to outside. Use a fish tape to pull the wire through.
- Along the exterior: Use wire molding or conduit to protect the wire from weather and damage.
- Under the door frame: If the wire is short, you can tuck it under the trim or threshold.
Keep the wire as short as possible to reduce voltage drop. Long runs (over 50 feet) may require thicker wire or a higher-voltage transformer.
Connect the Wire to the Transformer
Strip about 1/2 inch of insulation from each end of the low-voltage wire. Connect one wire to each terminal on the transformer’s secondary side (usually labeled “1” and “2”). Use wire nuts or terminal blocks to secure them.
Run the Wire to the Doorbell
Feed the wire through the wall or along the exterior to the doorbell location. Leave a little slack at both ends for easier connection.
Pro Tip: Label the wires at both ends (e.g., “T1” and “T2”) to avoid confusion later.
Step 4: Mount the Ring Doorbell
With the wire in place, it’s time to install the doorbell itself.
Prepare the Mounting Surface
Clean the area where you’ll mount the doorbell. Remove any old paint, dirt, or debris. If mounting on brick or concrete, use a masonry drill bit and anchors.
Drill Mounting Holes
Hold the mounting bracket against the wall and mark the screw holes with a pencil. Drill pilot holes, then secure the bracket with screws.
Connect the Wires
Strip about 1/4 inch of insulation from the ends of the low-voltage wires. Connect them to the terminals on the back of the Ring doorbell:
- One wire to the “Front” terminal
- The other wire to the “Trans” terminal
It doesn’t matter which wire goes where—Ring doorbells are not polarity-sensitive. Tighten the screws to secure the wires.
Attach the Doorbell
Slide the Ring doorbell onto the mounting bracket until it clicks into place. Make sure it’s level and secure.
Step 5: Test the Installation
Before celebrating, test your setup to ensure everything works.
Turn the Power Back On
Go to the breaker box and restore power to the circuit. Wait a few seconds for the transformer to activate.
Check the Doorbell
Open the Ring app on your phone and check if the doorbell appears online. Look for:
- A solid green light (indicates power and connection)
- Live view working
- Motion detection alerts
If the light is red or blinking, there may be a wiring issue or insufficient power.
Troubleshoot Common Issues
If the doorbell doesn’t power on:
- Double-check all wire connections at the transformer and doorbell
- Use a multimeter to test voltage at the doorbell terminals (should be 16-24V AC)
- Ensure the transformer is properly connected to 120V power
- Verify the breaker is on and the circuit is live
Note: If voltage is too low, the transformer may be undersized or the wire run too long.
Step 6: Secure and Finish the Installation
Once everything is working, tidy up the installation.
Secure Loose Wires
Use wire clips, conduit, or molding to keep wires neat and protected. Avoid sharp bends or pinching.
Install a Wire Cover (Optional)
For a clean look, install a wire cover along the exterior wall. These are available at hardware stores and come in various colors.
Test All Features
Test the doorbell button, motion alerts, night vision, and two-way audio. Make sure the app notifications work correctly.
Adjust Settings in the Ring App
Customize motion zones, notification preferences, and recording settings. Enable “Hardwired Power” in the device settings for optimal performance.
Troubleshooting Common Problems
Even with careful installation, issues can arise. Here’s how to fix the most common ones.
Doorbell Won’t Power On
- Check the breaker: Make sure power is restored to the circuit.
- Test the transformer: Use a multimeter to confirm it’s outputting 16-24V AC.
- Inspect wires: Look for loose, frayed, or disconnected wires.
Weak or Intermittent Signal
- Voltage drop: Long wire runs can reduce voltage. Use thicker wire or a higher-VA transformer.
- Poor Wi-Fi: Move your router closer or use a Wi-Fi extender.
Blinking Red Light
- This usually means low power. Check transformer specs and wire connections.
- Ensure the transformer is rated for at least 20VA.
No Sound or Chime
- If you have a mechanical chime, make sure it’s compatible with Ring.
- For digital chimes, check the app settings.
