Have you ever had a frustrating moment when your ADT Doorbell Camera flashes a red light? Don’t worry, you are not alone.

Continue reading this how-to guide to learn step-by-step solutions to resolve the problem.

Why does ADT Doorbell Camera Blink Red?

The ADT Doorbell Camera blinks red to indicate various status notifications or warnings.

A red blinking light usually indicates low battery levels, problems with network connectivity, or malfunctions with the camera’s operation.

This visual signal makes it easier for users to spot possible problems quickly and take the necessary action, like charging the battery, fixing the network connection, or getting in touch with customer support, when needed.

Now, let’s troubleshoot the issue.

Checking Battery Levels

To fix the blinking red issue with your ADT doorbell, start by checking the battery.

Sometimes, when the battery is low, the doorbell doesn’t work properly. Just take the doorbell off its mount and look at the battery indicator.

If it’s low, put in a new battery.

Use good-quality batteries that ADT suggests for best results.

Analyzing Power-related Issues

If the battery levels are fine, the next step is to analyze your doorbell for any power-related issues. Start by inspecting the power source.

Make sure the doorbell is firmly plugged into a power outlet or that the wires are properly connected if it’s hardwired.

Also, inspect the power cord and adapter for any signs of damage.

Resetting the Doorbell

If checking the battery levels and power source doesn’t resolve the issue, the next step is to reset the system.

This can often help in resolving any software glitches or conflicts causing the ADT doorbell blinking red problem.

To reset the system, follow these steps:

  1. Locate the reset button on the back or bottom of the doorbell camera.
  2. Press and hold the reset button for at least 10 seconds using a tiny pin or paperclip.
  3. Release the button once you see the LED indicator light flash, indicating that the reset is complete.
  4. After resetting your ADT doorbell, allow the doorbell camera to reboot and reconnect to the ADT network.

You can also restart your ADT doorbell in the Pulse app.

Restarting the Router

Sometimes, the ADT doorbell blinking red issue can be related to internet connectivity problems.

To rule out this possibility, try restarting your router. Here’s how you can do it:

  • Locate your router, then disconnect it from the power supply.
  • Wait for about 30 seconds and then plug it back in.
  • Allow the router to reboot and establish a stable internet connection.
  • Once the router is back online, check if the ADT doorbell blinking red issue persists.

Need More Help? Contact ADT Support

In case you’ve tried the troubleshooting steps mentioned above and the ADT doorbell is still blinking red, you may need to contact ADT support for further assistance.

They can provide further direction and support, to assist you in resolving the problem.


It can be annoying to encounter a red blinking light on your ADT doorbell camera.

However, you can fix the issue and restore your camera’s functionality by following the aforementioned fixes. 

Don’t forget to check the battery, analyze power problems, do a system reset, and restart your router as necessary. If none of this works, reach out to ADT’s customer service if the issue persists.
