Blink Camera Thumbnail Failed: How to Fix!

You’ve just set up your Blink security camera, eager to amp up your home’s safety game. But instead of seeing a crisp preview thumbnail, you’re greeted with a frustrating “Thumbnail Failed” error. It’s like planning a cozy movie night only to find your TV won’t turn on, it’s annoying, right?

Don’t worry, though; this hiccup isn’t a deal-breaker. While it might seem like a major glitch, the “Thumbnail Failed” issue is more common than you’d think and usually fixable. Whether it’s a hiccup in communication, a power supply issue, or a wonky wireless connection, there’s a way to troubleshoot and get things back on track. Let’s dive into what’s causing your Blink camera’s thumbnail to throw a tantrum and how you can fix it.

Poor Internet Connection

Your Blink camera relies heavily on a stable internet connection to function correctly. If you’re experiencing thumbnail loading errors, weak Wi-Fi signals or slow internet speeds could be the culprits.

The Blink system requires a minimum of 2Mbps upload speed to seamlessly generate and upload thumbnails to the app. Inadequate bandwidth or signal strength often results in these frustrating errors. To address this, ensure your router is optimally positioned and isn’t overcrowded with devices competing for bandwidth.

Camera Placement and Obstructions

The location of your Blink camera plays a pivotal role in its performance. Physical barriers between your camera and Wi-Fi router can significantly diminish signal strength, leading to thumbnail generation failures.

Walls, large furniture, or metal objects can obstruct the Wi-Fi signals. Moreover, if the camera is placed at the edge of your Wi-Fi network’s range, it may struggle to maintain a stable connection.

Reevaluating the camera’s placement, reducing obstructions, or using Wi-Fi extenders can vastly improve signal strength and, consequently, thumbnail loading times.

Outdated Firmware

Just like any tech gadget, your Blink camera requires the latest software to operate efficiently. Outdated firmware can lead to a myriad of issues, including the inability to generate thumbnails. Manufacturers regularly release updates to enhance functionality and fix known bugs.

It’s important to keep your Blink device’s firmware up to date to ensure all features work as intended. This includes the efficient generation of thumbnail images for a seamless user experience. Checking for and installing firmware updates through the Blink app can mitigate these issues and keep your camera functioning smoothly.

Person Holding a Camera

When you encounter a “Thumbnail Failed” error with your Blink camera, it can be frustrating. Don’t worry, though; you’re not out of options.

There are several steps you can take to resolve this issue and get your camera’s thumbnail generation back on track.

Restarting the Camera

The first step in troubleshooting any tech device, including your Blink camera, is to try turning it off and then back on.

This simple action can often resolve minor glitches that cause features like thumbnail generation to fail.

  • Turn off the camera using the Blink app or by physically disconnecting it.
  • Wait for about 10 seconds. This brief period allows the camera’s internal systems to fully reset.
  • Turn on the camera by reconnecting it or using the app.
  • After restarting, check if thumbnails are now successfully loading.

Checking Network Connectivity

A stable and robust network connection is crucial for your Blink camera to function correctly, including generating thumbnails. Here are a few steps to ensure your network isn’t the bottleneck:

  • Check your Wi-Fi signal strength near the camera. Weak signals can lead to failed thumbnails.
  • Restart your Wi-Fi router to clear any glitches affecting connectivity.
  • If using a dual-band router, try switching the camera to the other frequency band (5GHz or 2.4GHz). Some devices perform better on different bands.

Updating Firmware

Out-of-date firmware can cause a plethora of issues, including thumbnail generation failures. Ensuring your Blink camera and app are up-to-date is a key troubleshooting step:

  • Open the Blink app and navigate to the settings of the affected camera.
  • Look for an update option. If there’s a new firmware version available, proceed to update.
  • Follow the app’s instructions to complete the firmware update.
  • After the update, monitor your camera to see if the thumbnail issue is resolved.

Remember, these steps are meant to address common reasons why thumbnail generation might fail on your Blink camera. If you’ve tried these solutions without success, further investigation into specific circumstances or hardware issues may be necessary.


Facing a Blink camera thumbnail failure can be frustrating but it’s often a fixable issue. By following the steps we’ve outlined restarting your camera, ensuring your network connection is solid, and updating your camera’s firmware you’re well on your way to resolving it.

Remember, these solutions are your first line of defense. If you’re still encountering problems, it might be time to delve deeper into specific issues or consider reaching out for professional help. Here’s to getting your Blink camera back up and capturing those crucial moments without a hitch!
