What are the Consequences of Not Using a Sync Module for Your Devices?

Discover the essential benefits you’ll miss by not connecting your Blink video doorbell to a Sync module. One key advantage is the efficient use of battery power. While AA batteries are affordable and replaceable, you can also embrace sustainability by investing in rechargeable batteries.

Additionally, without a Sync module, you won’t have access to video clip storage. The Blink itself lacks local storage, meaning you’ll need a subscription plan for cloud storage of your video files. However, by utilizing the Sync module, you can bypass the subscription and store your videos directly onto a USB drive.

While losing these features may not be a deal breaker, consider how they could impact your decision to purchase a Blink video doorbell

To unlock advanced features like live view and motion detection for your Blink doorbells, a Sync Module is essential. While you can still access some functions without it, you’ll be restricted to “Event Response” mode, a basic option designed to save battery. To fully enjoy the live view and motion detection capabilities, it’s necessary to set up a Sync Module and reconfigure your camera within the system.

If your sync modules are not functioning properly or are not appearing in the app, you may need to reset them. The easiest way to do this is by unplugging the module from the power source and then plugging it back in. This should reset it.

If the issue persists, you can try using the reset button. The reset button is located next to the USB port of the flash drive. To activate it, you will need a paper clip to press the button. Hold it down for 5 seconds, and you should observe a sequence of red flashing lights, followed by blue flashing lights, and finally a solid green light.


A Sync module is not essential to operate your Blink video doorbell. While you may miss out on certain features, they are not crucial. Additionally, there are alternative options available if you prefer a different ecosystem or a smaller company.
