Why is a Blink Camera Blinking Red and Green?

If you see a blink camera blinking red and green, there are several different issues that can cause this.

First, it could be a problem with the camera’s battery or its internet connection. Alternatively, it could be a problem with the Sync Module.

Wi-Fi Connection

Blink cameras need a solid WiFi internet connection to function properly. This is essential for a number of features, including video recording and two-way audio.

If your blink camera flashes red or green, it may be unable to connect to the internet. This can be caused by a variety of reasons, including server issues or internet connectivity problems.

Your Blink camera works best with a non-cellular 2.4GHz wifi network with a high-speed connection and at least three bars of signal strength.

A good signal is important for your Sync Module to communicate with your camera(s). If you have trouble connecting to your camera, it could be that your sync module has poor signal strength or that the range between your sync module and your camera is too small.

To reconnect your Sync Module, tap Discover Device in the app. Then plug in your Sync Module and wait for the blinking blue light to appear. Next, scan the QR code on the Sync Module. This will give you a list of the serial number, new wifi network name and password, and signal strength.


The battery is an important part of the blink camera. It powers the camera and allows it to work with the Blink home monitoring app.

If the camera’s battery is running low, you may see it flashing red several times during recording. This indicates the batteries are getting close to being dead and should be replaced before they die completely.

When you buy new batteries for your blink camera, make sure that they are AA lithium non-chargeable and have the correct voltage. The Blink app’s battery indicator is often inaccurate, so you will want to use a multimeter to check the voltage on your batteries before putting them in the camera.

Sync Module

The Sync Module is the little device that connects your Blink cameras to a Wi-Fi network. It also relays commands and settings to devices in a system.

The Blink Sync Module can also be used to store video footage on local storage instead of relying on the cloud. This can be handy if you don’t have a Blink cloud subscription, but the storage capacity depends on the flash drive you use.

To reset the Sync Module, locate the reset button on the right side of it (near the USB port), then push and hold it until the red light comes on. It could take up to 30 seconds.

This action will restart the Sync Module back into setup mode, which should stop your camera from blinking. If the Sync Module still hasn’t stopped blinking after resetting it, you may need to contact Blink customer support.


Blink cameras are an excellent addition to your home, but sometimes they can have some issues with their settings. Luckily, this isn’t an insurmountable problem.

First, make sure the blink camera is connected to your Wi-Fi network. If it is, the LED light should change to blue.

If it isn’t, the issue might be with your internet connection or a faulty battery.

It is recommended that you pursue monthly maintenance of your blink security camera and batteries. This will ensure that you don’t have any issues in the future.

You can also perform a hard reset on the blink camera to fix this problem. This will reset the camera to its factory default settings before any problems occurred.

You can do this by pressing the reset button on the Sync Module. You’ll find this on the side of the device (near the USB port).
