How to reset a Blink Sync Module

Blink Sync module offline

Blink XT and XT2 cameras use a sync module to communicate with your wifi network. Sometimes the Blink sync module will freeze or stop working. Use the following info to get your Blink system up and running.

Reconfiguring the Sync Module

Caution: Only proceed  if your system is not working as expected, or if you are making network changes such as a new location or Wi-Fi password update.

When a Sync Module is not connected to the internet, the Blink app displays a banner and dims the thumbnail of affected cameras. You are notified according to the preferences you have set.

Delete and reinstall your Sync Module

  1. Tap the ? icon on the “Sync Module Offline” banner. You are sent to the Sync Module details screen.

  2. If you’re only updating the Wi-Fi password, tap Change Wi-Fi Network, and follow the instructions. Otherwise, tap Delete Sync Module.
    You are then presented with a popup suggesting you contact Customer Service.
    Dismiss the popup by tapping Ok.

  3. To delete a Sync Module, you are required to enter or scan its serial number. The number label can be found on the back of the Sync Module.
    When entered, tap Continue.

  4. You are presented with a final popup asking if you are sure.
    Tap “DELETE“.


    The Sync Module is deleted from your account. The System your Sync Module was attached to still exists, along with any associated cameras or other devices. A connected Sync Module will return the cameras to normal function.

  5. To add a Sync Module, navigate to the Home screen and tap the “add device”  + button in the upper right. You are sent to the Add Device screen.

  6. Tap Blink wireless camera system.

  7. Use your camera to scan the QR code, or enter the serial number manually. The Sync Module serial number is on the back and begins S/N 2 followed by eight digits. The Mini camera serial number is just below the QR code.
    Once the serial number has been entered, tap Continue.

  8. Next is to select a System for the Sync Module to associate with. You are shown an entry area to create a new System and a list of existing systems on the account. To retrieve the cameras and settings from before, connect your Sync Module to the System it was previously attached to.


    The app will now ask you to plug in your Sync Module or Mini Camera, if it is not already. About 30 seconds after being plugged in, a flashing blue light and solid green light pattern appears. It is important that the light pattern is present, otherwise you may have to contact support.
     Only when you see this light pattern, tap Discover Device in the Blink app.

  9. The app prompt states: “Blink” Wants to Join Wi-Fi Network “Blink-####”, where #### relates to the serial number of the device you are adding.
    Tap Join.

    Upon connection to the Blink app, the Sync Module provides a list of Wi-Fi networks that it can detect. Select the one being used by the Blink app, and enter the password. In the popup that appears, tap Join.
