Before you begin charging, it’s important to know which type of Alarm.com doorbell you have. Not all models use the same power source, and charging methods vary.

Battery-Powered Doorbells

These models run entirely on rechargeable lithium-ion batteries. They’re easy to install and don’t require wiring, making them ideal for renters or homes without existing doorbell wiring. Examples include:

Alarm.com ADC-VDB1
Alarm.com ADC-VDB2

These doorbells typically last 3–6 months on a single charge, depending on usage (like motion detection frequency and video recording).

Hardwired Doorbells with Backup Battery

Some Alarm.com doorbells are hardwired into your home’s electrical system but include a backup battery for power outages. These models include:

Alarm.com ADC-V723AC
Alarm.com ADC-V724AC

Even though they’re wired, the backup battery may still need occasional charging—especially if the power goes out frequently.

How to Identify Your Model

To confirm your doorbell type:

Open the Alarm.com app and go to Devices.
Select your doorbell and check the model number under Device Info.
Alternatively, look at the back of the doorbell or the packaging it came in.

Knowing your model ensures you follow the correct charging procedure and avoid potential damage.

What You’ll Need to Charge Your Doorbell

Gather these items before starting:

The original USB charging cable (usually micro-USB or USB-C)
A compatible power adapter (5V/1A or 5V/2A)
A clean, dry cloth
A small Phillips-head screwdriver (if your model requires removal)
A stable surface to place the doorbell while charging

Pro Tip: Always use the charger that came with your doorbell. Third-party chargers may deliver incorrect voltage and damage the battery.

Step 1: Check the Battery Level

Before removing your doorbell, check how much charge is left. This helps you decide whether a quick top-up is enough or if a full recharge is needed.

Using the Alarm.com App

Open the Alarm.com app on your smartphone or tablet.
Tap Devices at the bottom of the screen.
Find your doorbell and tap on it.
Look for the battery icon—usually in the top-right corner.

The app will show a percentage (e.g., 20%) or a visual battery bar. If it’s below 20%, it’s time to charge.

Signs Your Doorbell Needs Charging

Even if the app doesn’t show a low battery warning, watch for these signs:

The doorbell doesn’t ring or send notifications.
Live video is choppy or won’t load.
The LED light is dim or flickering.
Motion detection stops working.

If you notice any of these, proceed with charging.

Step 2: Safely Remove the Doorbell

Now that you’ve confirmed it’s time to charge, it’s time to take the doorbell off the wall.

For Battery-Powered Models

Most battery-powered Alarm.com doorbells use a simple slide-off design:

Stand on a stable step ladder if needed.
Gently press the release button (usually at the bottom or side of the doorbell).
Slide the doorbell downward or outward to detach it from the mounting plate.
Carefully disconnect the battery compartment if it’s separate.

For Hardwired Models

Hardwired doorbells require a bit more care:

Turn off the power at the circuit breaker to avoid electrical shock.
Use a Phillips-head screwdriver to remove the mounting screws.
Gently pull the doorbell away from the wall.
Disconnect the wires by loosening the terminal screws or unplugging the connector.
Label the wires (e.g., “Front,” “Trans”) so you can reconnect them correctly later.

Safety First: Never remove a hardwired doorbell without turning off the power. If you’re unsure, consult an electrician.

Step 3: Prepare the Doorbell for Charging

Once the doorbell is removed, prepare it for a safe and effective charge.

Clean the Contacts

Dust or debris on the charging port can interfere with power transfer.

Use a dry cloth to wipe the USB port and battery contacts.
Avoid using water or cleaning sprays—moisture can damage electronics.

Check for Damage

Inspect the doorbell for:

Cracks in the casing
Swollen or leaking battery (a serious safety hazard)
Corrosion on metal parts

If you see any damage, stop charging and contact Alarm.com support.

Choose the Right Charging Location

Charge your doorbell in a:

Cool, dry place (avoid direct sunlight or heaters)
Stable surface (like a table or counter)
Area away from children and pets

Never charge your doorbell outdoors or in a humid bathroom.

Step 4: Connect and Charge the Doorbell

Now it’s time to plug in and recharge.

Using the USB Cable

Plug the USB cable into the doorbell’s charging port (usually on the back or bottom).
Connect the other end to the power adapter.
Plug the adapter into a wall outlet.

Charging Indicators

Most Alarm.com doorbells show a light when charging:

Solid red light: Charging in progress.
Solid green or blue light: Fully charged.
Blinking red light: Charging error (check connections or cable).

If there’s no light, try a different cable or outlet.

How Long Does It Take to Charge?

Charging time varies by model and battery level:

From 0% to 100%: 4–6 hours
Top-up (e.g., 20% to 80%): 2–3 hours

Avoid overcharging. Once fully charged, unplug the doorbell to preserve battery health.

Step 5: Monitor Charging via the App

Even while charging, you can track progress in the Alarm.com app.

Check Battery Status

Open the app and go to Devices.
Select your doorbell.
The battery percentage will update in real time.

Some models also send a push notification when charging is complete.

Enable Low Battery Alerts

To avoid future surprises:

Go to Settings > Notifications.
Turn on Low Battery Alerts for your doorbell.

This way, you’ll get a warning before the battery dies.

Step 6: Reinstall the Doorbell

Once fully charged, it’s time to put your doorbell back.

For Battery-Powered Models

Reconnect the battery if it was detached.
Align the doorbell with the mounting plate.
Slide it upward or inward until it clicks into place.
Press firmly to ensure it’s secure.

For Hardwired Models

Reconnect the wires to the correct terminals.
Secure the doorbell to the mounting plate with screws.
Turn the power back on at the circuit breaker.
Wait 30–60 seconds for the doorbell to boot up.

Test the Doorbell

After reinstalling:

Press the doorbell button to test the chime.
Open the app and check live video.
Walk in front of the doorbell to test motion detection.

If everything works, you’re all set!

Troubleshooting Common Charging Issues

Sometimes, charging doesn’t go as planned. Here’s how to fix common problems.

Doorbell Won’t Charge

Check the cable: Try a different USB cable or power adapter.
Test the outlet: Plug in another device to confirm the outlet works.
Clean the port: Use a toothpick or compressed air to remove debris.
Restart the doorbell: Hold the power button for 10 seconds to reset it.

Battery Drains Too Fast

If your doorbell loses charge quickly:

Reduce motion detection sensitivity in the app.
Lower video quality or recording duration.
Check for Wi-Fi interference—move your router closer.
The battery may be aging—consider replacement.

Doorbell Won’t Turn On After Charging

Ensure it’s fully charged (wait at least 4 hours).
Try a different charger or cable.
Reset the doorbell by holding the button for 15 seconds.
Contact Alarm.com support if the issue persists.

Overheating During Charging

If the doorbell feels hot:

Unplug it immediately.
Let it cool in a shaded area.
Never charge in direct sunlight or near heat sources.
Contact support if overheating continues.

Best Practices for Long-Term Battery Health

To extend your doorbell’s battery life:

Charge Regularly

Don’t wait until the battery is dead. Charge when it drops below 30%.

Avoid Extreme Temperatures

Lithium-ion batteries degrade faster in heat or cold. Install your doorbell in a shaded area.

Use Original Accessories

Stick to the manufacturer’s charger and cable to prevent damage.

Update Firmware

Keep your doorbell’s software up to date via the app. Updates often include battery optimizations.

Schedule Maintenance

Every 3–6 months:

Check battery health in the app.
Clean the lens and sensors.
Test all features.

When to Replace the Battery

Even with good care, batteries wear out over time. Replace the battery if:

It won’t hold a charge for more than a few days.
The doorbell shuts off randomly.
You notice swelling or leakage.

Contact Alarm.com support or your security provider for a replacement. Some models allow DIY battery swaps, while others require professional service.
