Blink Cameras, like most home security products, rely on a Wi-Fi signal to operate. Except for the Blink Mini, all Blink Cameras come with a Sync Module, which serves as the central hub for all of your Blink Cameras. The Sync Module depends on a Wi-Fi signal, and without it, all of your Blink Cameras will be offline.

If your Blink Camera is offline, the Sync Module will indicate an offline status with a red light. If individual Blink Cameras are offline, the normal camera view on the Blink Home Monitor app will be greyed out. 

You’ll notice both of these indicators any time there is an interruption in service, whether it is directly from your router/modem or if there is a communication problem between one of the cameras and the Sync Module. In this article, we’ll cover the possible reasons why your Blink Camera(s) may go offline and how to resolve the issue through various troubleshooting steps.  

Why is My Blink Camera Offline?

There are several possibilities you’ll want to cross off the list if your Blink Camera(s) go offline:

  • Power failure disrupts the link between the Sync Module and the router
  • No/poor Wi-Fi signal transmission
  • Router and/or Blink Camera requires a reset

Troubleshooting Blink Camera Going Offline

Resetting your router is a common solution and works for many issues you may run into with Blink Cameras and devices. However, that’s just one fix; below, we’ll take a look at a couple of solutions for getting your Blink Camera back online.

Reset Router and Reconnect Sync Module

Unplug your Sync Module, followed by your router/modem. Give it about two minutes before you power everything back up. Start with the router, and once it is back online—with all of the LED indicators reflecting a successful connection—plug your Sync Module back in.

Once it is powered back up, it will indicate a successful connection with your Wi-Fi by displaying a green or blue light.

If you want to reset the Sync Module without rebooting your router, you’ll need a paperclip or similar tool.

  1. The reset button is located just to the right of the USB port. Insert the paperclip and press for 15 seconds, or until the LEDs show red and the device is reset.
  2. This will put the Sync Module in setup mode, and you’ll have to reconnect it to your router via the Blink Home Monitor app. To do this, go to the home screen on the app and select Add Device +.
  3. Now you’ll see a screen with the number of available devices listed. Select the text entry box and create a name to add a new system.
  4. When you add the Sync Module, you’ll be directed the rest of the way after you’ve power cycled and paired the device.

Power Cycle the Sync Module

Typically, a power failure simply reboots your router when the power returns. However, sometimes, the Sync Module and router connection won’t resume after power is restored.

If this happens, you’ll need to either reboot the router, followed by power cycling the Sync Module or cycling the Module alone. If neither works, you’ll need to reset the Sync Module and set up a new system again.

If your Blink Camera runs on batteries (which is the case for all Blink Cameras except for the Mini), you may need to replace them with fresh ones. Follow these steps for replacing your camera’s AA lithium batteries.

Check the Wi-Fi Signal

Wi-Fi signal is easy to disrupt, and any changes within your network may weaken the signal from the Sync Module to your cameras. Start by checking the signal strength of the Sync Module.

Open the Blink Home Monitor app and touch the Sync Module Status button to open the device settings. This screen will relay all of the current information for your Sync module, including the signal strength. You can check the signal strength for each of your Blink Cameras by selecting the symbol with three lines located next to your device nickname.

Once you’ve ascertained the signal strength for all of your Blink devices, you may consider moving the Sync Module closer to the router or repositioning the Blink Cameras to improve the signal.

You may also want to consider a range extender. The maximum signal distance between your Sync Module and the Blink Cameras in your network is 100 feet. A range extender will allow you to place the Sync Module farther away from the router, extending the overall range and signal strength of your Blink Cameras.

Final Thoughts

Blink Cameras are excellent home security devices that are reliable and long-lasting. Unfortunately, Wi-Fi signals and the disruptive nature of a smart home system, along with concrete, brick, and metal, may give your devices trouble from time to time.

Often, resetting your router or sync module will solve the problem. On rare occasions, your equipment may be defective. The good news is that Blink provides a one-year warranty for device defects. This includes the Sync Module as well. So long as you follow the instructions for returning your device, you’ll receive a replacement free of charge.

It’s also important to install your Blink Cameras and Sync Module in areas with reliable Wi-Fi coverage or purchase a range extender to ensure that all devices are in range. Knowing troubleshooting tips to keep your devices maintained and in good working order will keep your cameras in great shape and your home properly monitored and secured.
