Tools and Materials Checklist
- ADT doorbell camera (model compatible with your system)
- Screwdriver (Phillips and flathead)
- Drill and drill bits (if mounting on brick or concrete)
- Voltage tester (to confirm power is off)
- Wire strippers (if trimming old wires)
- Smartphone or tablet with the ADT Command app installed
- Stable Wi-Fi network (2.4 GHz recommended)
- Optional: Wire nuts, electrical tape, mounting anchors
Pro Tip: If you’re unsure about your doorbell’s wiring, take a photo of the existing setup before disconnecting anything. This helps you remember how to reconnect wires later.
Step 1: Check Compatibility and Power Requirements
Not all homes are ready for a smart doorbell camera. Before you buy or install, confirm your setup meets ADT’s requirements.
Verify Your Doorbell Transformer
Most ADT doorbell cameras require a transformer that outputs between 8–24 volts AC. Older homes may have lower voltage (6V), which won’t power the camera reliably.
To check:
- Turn off power at the breaker.
- Remove your existing doorbell button.
- Use a multimeter to test the voltage across the two wires.
If the reading is below 8V, you may need to upgrade your transformer. ADT recommends a 16V, 10VA transformer for optimal performance. You can purchase one online or at a hardware store.
Check Your Chime Type
ADT doorbell cameras work with both mechanical (ding-dong) and digital (electronic) chimes. However, some digital chimes may require a resistor to prevent buzzing or malfunction.
If your chime is digital, check the manufacturer’s specs or contact ADT support to see if a resistor is needed. Most ADT models include a resistor in the box, but it’s good to confirm.
Ensure Wi-Fi Coverage
Your doorbell needs a strong Wi-Fi signal to stream video and send alerts. Use a Wi-Fi analyzer app (like NetSpot or Wi-Fi Analyzer) to check signal strength at your front door.
If the signal is weak, consider:
- Moving your router closer to the front door
- Installing a Wi-Fi extender or mesh network
- Using a powerline adapter with Ethernet
Note: ADT doorbell cameras only support 2.4 GHz Wi-Fi networks. 5 GHz networks are not compatible.
Step 2: Turn Off Power and Remove the Old Doorbell
Safety first! Working with electrical wiring can be dangerous if you don’t disconnect the power.
Locate Your Circuit Breaker
Find the breaker that controls your doorbell. It’s often labeled “doorbell,” “chime,” or “front door.” If you’re unsure, turn off the main breaker to be safe.
Test the Wires
After turning off the power, remove the old doorbell button and use a voltage tester to confirm no current is flowing. Touch the probes to the two wires—if the tester lights up, the power is still on.
If power is still present, double-check the breaker or consult an electrician.
Disconnect and Label Wires
Carefully unscrew the wires from the old doorbell. Most have two wires: one labeled “Front” and one “Trans” (transformer). If your doorbell has more than two wires, label them with tape before disconnecting.
Keep the wires separated and avoid letting them fall back into the wall. You can tape them to the wall or use a wire holder.
Step 3: Install the ADT Doorbell Camera Mounting Plate
The mounting plate secures your doorbell camera to the wall and connects the wires.
Position the Mounting Plate
Hold the ADT mounting plate against the wall where you want the doorbell. The ideal height is 48–52 inches from the ground—eye level for most visitors.
Use a level to ensure the plate is straight. Mark the screw holes with a pencil.
Drill Pilot Holes (If Needed)
If you’re mounting on wood, you can screw directly into the wall. For brick, stucco, or concrete, drill pilot holes and use wall anchors.
Use a drill bit slightly smaller than your anchors. Tap the anchors gently into place with a hammer.
Attach the Mounting Plate
Align the plate with the holes and secure it with screws. Make sure it’s tight and level—this ensures the camera stays stable and angled correctly.
Pro Tip: If your doorbell is near a corner or under an eave, angle the plate slightly outward so the camera has a clear view of the walkway.
Step 4: Connect the Wires to the ADT Doorbell Camera
Now it’s time to wire your new doorbell camera. This step is straightforward if you labeled your wires earlier.
Prepare the Wires
If the wire ends are frayed or too short, trim them with wire strippers to expose about 1/4 inch of copper. Twist the strands gently to keep them neat.
Connect to the Mounting Plate
Most ADT doorbell cameras have a mounting plate with screw terminals or push-in connectors. Follow these steps:
- Insert the “Front” wire into the terminal labeled “Front” or “F.”
- Insert the “Trans” wire into the terminal labeled “Transformer” or “T.”
- Tighten the screws or press the wire firmly into the push-in slot.
Double-check that the wires are secure and not touching each other.
Attach the Camera to the Plate
Align the camera with the mounting plate and slide it into place. You’ll hear a click when it’s locked. Some models require you to tighten a small security screw at the bottom to prevent tampering.
Important: Don’t turn the power back on yet. We’ll do that after the app setup.
Step 5: Download and Set Up the ADT Command App
The ADT Command app is your control center for the doorbell camera. It handles setup, live viewing, alerts, and system integration.
Download the App
Search for “ADT Command” in the Apple App Store or Google Play Store. Download and install it on your smartphone or tablet.
Log In or Create an Account
If you already have an ADT security system, log in with your existing credentials. If not, create a new account using your email and a secure password.
You’ll need to verify your email and phone number during setup.
Add Your Doorbell Camera
Once logged in:
- Tap the “+” icon or “Add Device”
- Select “Doorbell Camera” from the list
- Follow the on-screen prompts
The app will ask you to scan the QR code on the back of your doorbell camera or enter the serial number manually.
Step 6: Connect the Doorbell to Wi-Fi
Your doorbell needs a strong Wi-Fi connection to function properly. The app will guide you through this step.
Enter Wi-Fi Credentials
The app will prompt you to select your Wi-Fi network and enter the password. Make sure you’re connecting to a 2.4 GHz network—5 GHz won’t work.
If your network name (SSID) doesn’t show up, move closer to your router or check if the network is hidden.
Wait for Connection
The doorbell will attempt to connect. This may take 1–2 minutes. You’ll see a progress bar in the app.
If it fails, try the following:
- Restart your router
- Move the doorbell closer to the router during setup
- Ensure the password is correct
- Reset the doorbell (see troubleshooting section)
Once connected, the app will confirm success and move to the next step.
Step 7: Configure Settings and Preferences
Now that your doorbell is online, customize it to fit your lifestyle.
Set Up Motion Zones
You can define areas where motion detection is active. For example, you might want alerts only when someone approaches the door, not when a car drives by.
In the app:
- Go to “Device Settings” > “Motion Detection”
- Draw zones on the camera view
- Adjust sensitivity (low, medium, high)
Enable Two-Way Audio
Test the microphone and speaker by tapping the talk button in the app. Speak and listen for clear audio.
If sound is muffled, check that the camera isn’t blocked by dirt or debris.
Set Notification Preferences
Choose when and how you want to receive alerts:
- Instant alerts for motion or doorbell presses
- Quiet hours (e.g., no alerts between 10 PM and 7 AM)
- Email or push notifications
Link to ADT Security System (If Applicable)
If you have an ADT security system, the doorbell camera can integrate with it. This allows you to view the camera feed from your security panel or receive alerts through the system.
In the app, go to “System Settings” and follow the prompts to sync devices.
Step 8: Turn On Power and Test the System
You’re almost done! Now it’s time to restore power and test everything.
Restore Power at the Breaker
Go back to your circuit breaker and turn the doorbell circuit back on. Wait 30 seconds for the system to power up.
Check the Doorbell Light
Most ADT doorbell cameras have an LED light that indicates status:
- Solid blue: Connected and ready
- Blinking blue: Connecting to Wi-Fi
- Red or amber: Error or low power
If the light is red, check the wiring or transformer voltage.
Test the Doorbell
Press the doorbell button. You should hear the chime inside and receive a notification on your phone.
Open the ADT Command app and check:
- Live video feed is clear
- Motion detection triggers alerts
- Two-way audio works
- Night vision activates in low light
Walk in front of the camera to test motion sensitivity. Adjust zones if needed.
