Blink Sync Module (The Ultimate Guide)

Last updated on April 13th, 2024

Did someone tell you that you need a Sync Module for your Blink cameras? They were not wrong. If you have multiple cameras, they become easy to manage with the module. But you might want to think if you need one for a single camera. We’ll tell you all about it in detail, but let’s first understand: What is a Blink Sync Module?

A Sync Module is a small rectangular device that uses your local Wi-Fi network to sync the recording from your cameras. The videos are stored locally on a USB that you’ll connect to it. It can connect up to 10 cameras together and form a system. All these cameras in the system are assigned a single IP address so you can track them collectively.

It has a port for a USB drive and one micro USB port for the power source. You get the power cord in the box, but the USB is not included. Recordings will not be saved locally if you don’t connect the USB to the module. Any USB smaller than 1 GB and larger than 256 GB is not recognized by the device.

Note: The Blink Video Doorbell and Mini cameras do not require a Sync Module 2.

Can I use a Blink camera without the Sync Module?

Yes, you can use a Blink camera without the Sync Module. But you’ll have to buy the Blink Subscription in that case. All the recorded videos will be saved because of the subscription. The videos are automatically backed up to the cloud every 24 hours. You can view them anytime on your app.

The table below compares the original and second-generation models of the Sync Module.

Connecting a Blink camera to the Sync Module

Before you connect a camera to the module, you have to set up your Blink app and connect the module with it. Once that is done, you can add and connect all your cameras one by one to the module. You can even add a new Sync Module to an existing system by following the same procedure.

Using multiple Sync Modules

Can you connect 2 Sync Modules to the same app? Yes, you can. A single module can only accommodate 10 devices. If you have more than 10 devices, naturally, you’ll need a second module. This, too, can be easily set up as the first one. You have to follow the same procedure. But you cannot connect a single camera to multiple modules.

Managing recordings from the Sync module


Now that you know what the module does and how to set it up, it’s time to understand how to view the saved data. All the recorded videos are saved to the connected USB. You can plug this drive into your laptop/computer/mobile and view all the saved recordings. You can keep the ones you want and delete others.

You must ensure that the drive always has more than 375 GB of space to store more recordings. Because if it doesn’t, further recordings won’t be stored, and you’ll lose them forever. The storage capacity of the module is only as much as the attached pen drive.

The live feed is always accessible from the Blink app. You can’t view it via the Sync device. It only contains videos that are recorded due to triggered motion.


If you are wondering how I can delete the recordings I don’t want, here’s how. You can’t do it directly from the module. You must remove the pen drive and connect it to your laptop. Now, you can choose and select the recordings you don’t want and press the delete button. These videos will be permanently deleted, and there’s no way to restore them.

Alternatively, you can delete the videos from the list of local files from the Blink app. But you can only view the first 1000 recordings from the last 30 days on the app. If you want to delete the rest, you’ll have to use the first method.

If you don’t want the hassle of deleting your videos, you can opt for the Blink Subscription. It automatically deletes videos 60 days after they are captured.

The Blink Sync module is a one-time investment for local data storage. You can link up to 10 cameras to a single module. Whereas, Blink Subscription can be bought for $3/month and $30/year for a single camera and $10/month and $100/year for more than one camera. On the second subscription, you can connect up to 10 cams.

Do I need a Blink Subscription when I have the Sync Module?

No, you don’t need a Blink Subscription when you have a Sync Module. All the recorded videos will be safely stored in the local storage as long as a USB is connected. But, if you have multiple cameras and a Blink Subscription without the module, it gets difficult to manage. So, you’ll need the module to sync all the cameras so you can view all their streams together instead of separately.

If you are facing random errors with your Sync Module and you are unable to pinpoint the cause, then performing a reset is always a good choice. If you are wondering how to reset the Blink Sync Module, then follow the below instructions carefully.

Step 1: Locate the Blink Sync Module reset button on the module.

Step 2: Press and hold the reset button for 5 seconds.

Step 3: Release the button and wait for the indicator light to turn solid green.

Your device is now successfully reset. You can connect it to the app by using the setup process.
