ADT Doorbell flashing red

If you’ve noticed your Blink doorbell blinking red, you’re likely wondering what it means. The blinking red light on your Blink doorbell could signal various conditions, from low battery levels to recording activity or potential connectivity issues. Understanding the reasons behind the red blinking light can help you troubleshoot and ensure your doorbell is functioning optimally.

What are the Causes of ADT Doorbell Flashing Red?

When the red light on your ADT doorbell starts blinking, it means there’s an issue that needs instant attention. Don’t worry, we’re here to help you figure out and fix what’s wrong with your camera.

Different LED light flashing patterns on a camera and their corresponding meanings:

Blinking Red continuously

  • If the LED is continuously blinking red, it could signal a complete loss of connection, router issues, or weaker-than-usual Wi-Fi signal.
  • Ensure a strong Wi-Fi connection with at least 90% signal strength and 2 Mbps upload speed for the doorbell camera to work smoothly.
  • Watch for a red circle around the ADT doorbell, signalling an unstable internet. Once fixed, the blue light indicating a solid connection will return.
  • A low battery or the need for a battery change can also cause the red light to blink on an ADT doorbell.
  • The doorbell may flash red to alert you when the battery is running low or needs replacement.
  • Red LED flashing also could be due to a malfunctioning router. 


Check online to see how fast your internet is running. Make sure your doorbell is on a stable Wi-Fi network as weak signals can cause issues.

If Wi-Fi seems weak, try moving the router closer or using a range extender for a stronger signal.Ensure that a proper internet connection is established. You could attempt restarting your modem/router to refresh the internet connection. 

you may monitor the system’s battery life via the ADT pulse app.This app  features a low-battery warning, as well as a battery level indicator that you can check at any time. 

Red LED on for 5 seconds then off

If the LED is on for 5 seconds and then turns off, the WPS function has most probably failed.

Solution: If your WPS setup fails on your ADT doorbell, try restarting the doorbell and your Wi-Fi router, then attempt the WPS setup again. 

Intermittent Blinking Red

If the LED is blinking for 2 seconds, means AC power is disconnected.

Overheating: The camera might get too hot from sunlight or use it a lot. 

Solution: Move it to a cooler place or use it less.


Ensure that the power adapter of the system is firmly plugged into an electrical outlet provided there is availability of power in your residence.

Once the power adapter connection is verified, inspect the circuit breaker box for any switches that are set to OFF and toggle them to ON.

To check the outlet’s functionality, disconnect the adapter of your system and utilise a small appliance. If it fails to work properly, seek assistance from an electrician and consider using a temporary extension cord.

Power Cycle ADT Doorbell Camera

A mere power cycle can be an easy fix for minor software or hardware problems with the doorbell camera. To initiate this process, unplug the device from the power source for roughly half a minute before reconnecting it again. Let it restart and restore connectivity for a while so that the process is finished.

Reset Your ADT Doorbell

A reset can indeed help resolve various issues, including a red LED blinking problem.

Resetting your ADT doorbell camera can often clear temporary glitches or errors that may be causing the red LED to blink.

If you’re facing this problem, it’s worth trying a reset to see if it resolves the issue. Just make sure to follow the proper reset procedure for your specific device to avoid any data loss or other complications.

ADT Doorbell Blinking Red and Green

The blinking of the red and green LED lights on your ADT Doorbell can occur due to various reasons, each leading to different blinking patterns.

LED  Blinking green on your ADT doorbell camera

This indicates that the WPS (Wi-Fi Protected Setup) connection is active. Pressing the Ring button, the LED would be turned to blinking green for the WPS process.

WPS is a method used to easily connect devices to a wireless network without entering a password. When the green light is blinking, it means that the doorbell camera is in the process of connecting to your Wi-Fi network using WPS. Once the connection is successfully established, the green light may change to a steady glow or turn off, depending on the device’s design.

LED Spinning green on your ADT doorbell camera

This indicates that the firmware of the camera is being upgraded. Firmware upgrades are important as they can bring improvements, bug fixes, and new features to your device.

During the upgrade process, the spinning green light signifies that the camera is in the process of updating its internal software. It’s essential to allow the upgrade to complete without interruption to ensure that your camera functions optimally with the latest improvements and enhancements.

Wrapping up

In conclusion, the ADT Doorbell blinking red is a clear indicator of underlying issues that need attention. Whether it’s due to low battery, unstable internet, or other factors, addressing these issues promptly can restore the doorbell to optimal functionality.
