Blink Camera Thumbnail Failed: How to Fix [2022]

I noticed that my outdoor Blink Camera has not responded to my commands and instead pushed weird error messages such as Thumbnail Failed.

This minor annoyance became a major deal for me when I realized that the camera was not recording for a while.

So I sought out ways to fix this issue and was surprised by just how many people have faced similar error messages popping up.

I made this troubleshooting guide so that you can fix the 'Thumbnail Failed error' on your Blink Camera.

To fix Thumbnail Failed error on Blink camera, bring the sync module close to the WiFi. Update the sync module and the status of your Blink Camera. If the issue persists, power cycle the camera and the internet router. If all else fails, use the RouteThis app to test for other issues.

Bring the Sync Module as Close to the WiFi as Possible

Bring the Sync Module as Close to the WiFi as Possible

The sync module on your Blink Camera is responsible for relaying commands and network information to the devices in the system. When the Blink App cannot communicate properly with the sync module, various error messages pop up.

Fixing the communication gap between the Blink Camera's sync module and the internet connection with which the Blink App connects may solve the issue.

The easiest way to bridge this gap is to simply make sure that the sync module sits in an area with a great network range.

Make sure the distance between the Blink camera and the sync module, as well as the distance between the sync module and the internet router, is as little as possible.

You can also check the signal directly from the Blink app to gauge the best results with your Blink camera:

  • Open the Blink app on your supported smart device.
  • Tap on the sync module icon on the home screen to enter the sync module settings.
  • The signal strength is shown as a WiFi icon.

It is recommended to stay somewhere in the range of 3 bars of signal strength in order to get the best results.

Update the Sync Module Firmware

Update the Sync Module Firmware

Sometimes the sync module can misbehave due to a bad firmware update, or due to a newer feature from the Blink app that the older firmware doesn't support.

In such cases, it is best to simply update your sync module firmware to the latest version available for your Blink camera.

Unfortunately, there is no manual method of updating the firmware of your Blink camera.

But quite a lot of Blink camera users have claimed that the sync module updates on its own when left plugged in overnight under a strong internet connection.

So as of writing this article, that is the only way to update the firmware of your Blink camera sync module unofficially.

Update the Status of the Blink Camera

Update the Status of the Blink Camera

Fortunately, updating the status of the Blink camera is a much easier task and is something that Blink has added to their Blink app.

This is also one of the steps that helped a lot of users solve the thumbnail failed error on their Blink cameras.

In order to properly update the status of your Blink camera, simply follow the steps given below:

  • Open the Blink app on your supported smart device.
  • Tap on the Settings icon on the home screen next to your camera's nickname to enter the camera settings.
  • At the bottom of the page, click on the Update icon beside the last updated option.

This updates the sync module and the Blink camera by manually forcing the sync process to work.

Power Cycle the Internet Modem and Blink Camera

Power Cycle the Internet Modem and Blink Camera

A power cycle seemingly is a very simple fix that almost everyone unintentionally does with their devices, but it is a very key step in the troubleshooting world.

It essentially is a reboot for the hardware of the device, making sure that the charges are evenly distributed to the internal components for best performance.

Since the internet router is responsible for relaying the proper signal, it is a prime candidate to perform a simple power cycle on.

To properly perform a power cycle on your Internet router, simply follow the steps given below:

  • Unplug the internet router from its power source.
  • Let the router sit idle powered off for about a minute.
  • Long press the buttons on the router to make sure all the charges from within the system are discharged.
  • Plug the internet router back into its power source.
  • Let the router sit idle powered on for about a minute.

The next step is to do the same with your Blink Camera.

In order to properly perform a power cycle on your Blink camera, simply follow the steps given below:

  • Remove the batteries from the Blink camera.
  • Let the camera sit idle powered off for about a minute.
  • Long press the buttons on the camera to make sure all the charges from within the system are discharged.
  • Put the batteries back into the camera. Make sure they are fully charged.
  • Let the camera sit idle powered on for about a minute.
