How to set up your replacement sync module in an existing system

If you have just received a replacement Sync Module through our RMA process or are upgrading to a new Sync Module 2, you will need to delete the original Sync Module before you can add the new one to your existing system. You will not have to delete or add any cameras during this process. Once the new Sync Module has been added, you may use the system again immediately. 

The following steps explain how to first delete your Sync Module.

To delete your Sync Module

1. To start, tap the "Sync Module" icon and you are sent to the Sync Module details screen.


2. Next tap Delete Sync Module.
You are then presented with a popup suggesting you contact Customer Service.
Dismiss the popup by tapping OK.

5. As a final step, unplug the Sync Module to clear any old settings.

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.


Once your older Sync Module is removed, you then have the option to add your new one in that same system.

Add a Sync Module to an existing system

1. From the home screen, tap the Add Device + icon.

2. The Add Device screen displays your device options.

  • Blink wireless camera system - A system contains a Sync Module and Blink Outdoor, Indoor (2nd Generation), XT2, XT, or 1st Generation Indoor camera. Start here if you have these cameras.

  • Blink wireless camera - This option adds a Blink Outdoor, Indoor (2nd Generation), XT2, XT, or 1st Generation Indoor camera after you have added a Sync Module.

  • Mini camera - The Mini camera does not require a Sync Module as it manages its own system, but a Mini camera will act like other Blink cameras when it is added to a system managed by Sync Module. Your selection opens the QR code scanning screen.

3. The serial number is also printed as a QR code. To scan a QR code, the Blink app requires permission to access the camera on your mobile device.

Tap OK to permit the Blink app to scan the QR code, automatically entering the serial number. If you prefer, you can deny access to the camera by tapping Don't Allow and enter the serial number manually.
