Smart doorbells have made it easier to manage who comes into your home. The ADT doorbell, for example, lets you see and communicate with anyone who knocks on your front door. But what does it mean when your ADT doorbell starts blinking red?

When the ADT doorbell starts blinking red, it could mean one of two things. Either the doorbell’s battery is low, or the internet connection is unstable. You can fix these problems by charging your ADT doorbell and ensuring a stable internet connection.

Below, we’ll discuss the reasons why your ADT doorbell is blinking red and what to do to solve the problem. Keep reading to get answers to your questions and more!

Why is My ADT Doorbell Blinking Red?

The ADT doorbell uses different colored lights to indicate different statuses to users.

If your doorbell is blinking red light, it could mean:

  • Your doorbell battery is low.
  • Your internet connection is unstable.

Below, we’ll discuss these causes and offer some potential solutions.

Your Doorbell Battery is Low

When your ADT doorbell suddenly starts blinking rapidly, it often means the batteries are low. The doorbell will power off if you don’t charge your battery soon.

If you have push notifications turned on, the ADT app will notify you whenever your battery is running low.

If you need to charge your ADT doorbell, grab a mini-USB cord and follow the steps below:

  • Remove the doorbell’s faceplate to access the charging port.
  • Plug one end of the mini-USB cord into the charging port and the other into a wall socket.
  • Wait for the battery to charge to 100%. The light will turn solid blue when your doorbell is fully charged.
  • Unplug the USB cord and replace the faceplate.

A single battery charge should last up to three months.

Your Internet Connection is Unstable

The ADT doorbell requires a strong, stable internet connection to function properly.

If the batteries don’t need to be charged, a blinking red light could tell you that your internet connection is unstable.

Your router could have come offline, or it could be too far from the doorbell to offer a strong signal.

If the batteries are not the problem, it’s time to check your internet connection.

One can make changes to WiFi using the control portal on the doorbell.

  • Click “Video” on the left side of the screen.
  • Select “Settings.”
  • Locate “Wireless Network.”

Proceed to examine the WiFi connection and internet stability, then make changes if necessary.

If the connection is slow, try restarting your router or moving it closer to your ADT doorbell.

Erasing any connection issues should eliminate the blinking red light.

If your ADT doorbell is still blinking red, you can resort to a factory reset.

How to Factory Reset an ADT Doorbell

Performing a factory reset on a device is, in most cases, a last resort troubleshooting method.

When all else fails, this often solves any problems you’re having with a device.

To perform a factory reset on an ADT doorbell, hold down the small button beside the power port for 10 seconds to power off the doorbell. Within a minute or two, the device should power back on.

This method will only work for a wireless ADT doorbell.

If you have a wired ADT doorbell, ensure the doorbell is plugged into a power source, then hold the square button at the back for 15 seconds.

Within a minute or two, your doorbell camera should come back on.

Will My ADT Doorbell Work When the Power is Out?

Now that you know the ADT Doorbell needs sufficient power and an active internet connection to function, you may be wondering if it will work in a power outage.

The ADT doorbell is equipped with a backup battery, which will activate during a power outage. However, you will not be able to use the video features without an active internet connection.

In Conclusion

Smart doorbells are an effective security solution for your home.

But, if your ADT doorbell is blinking red light, it either has a low battery or a poor internet connection.

Luckily, this problem can easily be fixed by charging the doorbell or reconnecting to your WiFi network.
