Before diving into the installation, make sure you have all the tools and materials ready. Rushing out to buy something mid-install can be frustrating—so let’s get prepared.
Tools and Materials Checklist
- Alarm.com doorbell camera (compatible model)
- Screwdriver (usually Phillips head)
- Wire strippers (if wires need trimming)
- Voltage tester (optional but recommended)
- Drill and drill bits (if mounting on brick or concrete)
- Level (to keep the doorbell straight)
- Smartphone or tablet with the Alarm.com app installed
- Stable Wi-Fi network (2.4 GHz recommended)
- Power drill (optional, for mounting)
- Electrical tape (for securing wires)
Check Compatibility
Not all doorbells work with every home setup. Before installing your Alarm.com doorbell camera, verify compatibility with your existing system.
First, confirm your doorbell is designed for Alarm.com. These are often sold through authorized dealers or security providers like ADT, Vivint, or Brinks. Look for “Alarm.com compatible” or “Powered by Alarm.com” on the packaging or product listing.
Next, check your existing doorbell wiring. Most Alarm.com doorbell cameras require a transformer that supplies 16–24 volts AC. If your current doorbell works, you likely have the right voltage—but it’s smart to double-check.
Use a multimeter or voltage tester at the doorbell terminals. If the reading is below 16V, your transformer may be too weak. In that case, you’ll need to upgrade it before installing the new doorbell.
Also, ensure your chime is mechanical (not digital). Some digital chimes don’t work well with smart doorbells unless a bypass resistor is installed. If you’re unsure, consult the Alarm.com compatibility guide or contact your provider.
Download the Alarm.com App
The Alarm.com app is your control center for the doorbell camera. It’s available for free on the Apple App Store and Google Play.
Download and install the app on your smartphone or tablet. If you already use Alarm.com for other security devices (like sensors or cameras), log in with your existing account. If not, you’ll need to create one—usually through your security provider.
Having the app ready before installation saves time. You’ll use it to scan the doorbell’s QR code, connect to Wi-Fi, and complete the setup.
Step 1: Turn Off the Power
Safety first! Working with electrical wiring can be dangerous if the power is on.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (breaker box). Look for the circuit labeled “doorbell,” “chime,” or something similar. If there’s no label, you may need to test circuits by turning them off one at a time and checking if your doorbell stops working.
Once you find the right breaker, switch it to the “OFF” position.
Test the Power
To be extra safe, press your existing doorbell button. If the chime doesn’t sound, the power is off. For added certainty, use a non-contact voltage tester near the doorbell wires. If it doesn’t beep or light up, you’re good to go.
Never skip this step. Even low-voltage systems can cause shocks or damage your new doorbell.
Step 2: Remove the Old Doorbell
Now that the power is off, it’s time to remove the existing doorbell.
Unscrew the Faceplate
Use your screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the faceplate away from the wall. You should see two wires connected to terminals (usually labeled “Front” and “Trans” or just two screws).
Disconnect the Wires
Loosen the terminal screws and carefully remove the wires. Don’t let them fall back into the wall. To prevent this, wrap the wire ends with electrical tape or use a piece of tape to hold them in place.
Take a photo of the wiring setup before disconnecting. This can help if you need to reference it later.
Remove the Mounting Bracket (if needed)
Some doorbells have a separate mounting bracket. If yours does, unscrew it from the wall. You may reuse it if it’s compatible with your new Alarm.com doorbell, but most smart doorbells come with their own bracket.
Step 3: Install the New Mounting Bracket
Your Alarm.com doorbell camera should come with a mounting bracket. This holds the device securely and often includes alignment guides.
Position the Bracket
Hold the new bracket against the wall where the old doorbell was. Use a level to make sure it’s straight. Mark the screw holes with a pencil.
If you’re mounting on wood, you can screw directly into the wall. For brick, stucco, or concrete, you’ll need to drill pilot holes and use wall anchors.
Secure the Bracket
Drill the holes (if needed), then screw the bracket into place. Make sure it’s tight and level. A wobbly bracket can affect the camera angle and make installation frustrating.
Feed the Wires Through
Thread the two doorbell wires through the center hole in the bracket. This keeps them accessible when you attach the doorbell.
Step 4: Connect the Wires to the Doorbell
Now it’s time to connect your doorbell camera to the wiring.
Identify the Terminals
Most Alarm.com doorbell cameras have two terminals: one for the “Front” wire and one for the “Transformer” wire. These are usually labeled on the back of the device or in the manual.
Strip the Wire Ends (if needed)
If the wire ends are frayed or too short, use wire strippers to expose about 1/4 inch of copper. Be careful not to cut too much—you need enough to make a solid connection.
Attach the Wires
Loosen the terminal screws on the doorbell. Insert one wire into each terminal and tighten the screws securely. It doesn’t matter which wire goes where—most smart doorbells are polarity-independent.
Double-check that the connections are tight and no bare wire is exposed.
Secure with Electrical Tape (Optional)
For extra safety, wrap the wire connections with electrical tape. This prevents accidental shorts and keeps things neat.
Step 5: Attach the Doorbell to the Bracket
With the wires connected, it’s time to mount the doorbell.
Align and Snap Into Place
Hold the doorbell camera against the bracket. Most models snap on securely—listen for a click. Some may require you to slide it into place or tighten a set screw.
Make sure it’s firmly attached and doesn’t wobble.
Adjust the Angle
Tilt the doorbell slightly downward so the camera has a clear view of your doorstep. Avoid pointing it directly at the sun or bright lights, which can cause glare.
Step 6: Restore Power and Test the Chime
Now that everything is installed, it’s time to turn the power back on.
Flip the Breaker
Go back to your circuit breaker and switch the doorbell circuit back to “ON.”
Test the Doorbell
Press the doorbell button. Your mechanical chime should ring. If it doesn’t, double-check your wiring and connections.
If you have a digital chime and it’s not working, you may need a bypass resistor. These are small devices that simulate the electrical load of a traditional doorbell. Contact Alarm.com support or your provider for guidance.
Step 7: Connect to Wi-Fi Using the Alarm.com App
This is where the magic happens—connecting your doorbell to your home network.
Open the Alarm.com App
Launch the app on your smartphone or tablet. Log in to your account.
Add a New Device
Tap the menu (usually three lines or a “+” icon) and select “Add Device” or “Add Camera.” Choose “Doorbell Camera” from the list.
Scan the QR Code
Your doorbell should have a QR code on the back or in the packaging. Use your phone’s camera to scan it. The app will recognize the device and begin the pairing process.
Connect to Wi-Fi
The app will prompt you to select your Wi-Fi network and enter the password. Make sure you’re on a 2.4 GHz network—most doorbell cameras don’t support 5 GHz.
Wait while the doorbell connects. This can take 1–2 minutes. Don’t walk away—the app may ask you to confirm settings or wait for a signal.
Name Your Doorbell
Once connected, give your doorbell a name (like “Front Door” or “Main Entrance”). This helps if you have multiple cameras.
Step 8: Configure Settings and Features
Now that your doorbell is online, customize it to fit your needs.
Set Up Motion Zones
In the app, go to the camera settings and enable motion detection. You can draw zones to focus on areas like your walkway or driveway—and ignore trees or passing cars.
Adjust Sensitivity
Too many false alerts? Lower the motion sensitivity. Want to catch every visitor? Increase it. Find the right balance for your home.
Enable Two-Way Audio
Test the microphone and speaker. When someone presses the button, you should be able to talk to them through the app.
Set Up Alerts
Choose how you want to be notified: push notifications, email, or both. You can also set quiet hours to avoid alerts at night.
Enable Night Vision
Most Alarm.com doorbells have infrared night vision. Make sure it’s turned on in the settings for clear footage after dark.
Step 9: Test Everything
Before calling it a day, run a full test.
Check Live Video
Open the app and view the live feed. Make sure the image is clear, the angle is right, and there’s no glare or distortion.
Test Motion Alerts
Walk in front of the doorbell. You should receive a notification within a few seconds.
Test Two-Way Talk
Press the doorbell button (or simulate a press in the app). Speak and listen—audio should be clear on both ends.
Review Recorded Clips
If your plan includes cloud recording, check that clips are being saved. Most Alarm.com plans offer 14–30 days of storage.
