Blink Sync Module

Are you looking for a way to aggregate multiple security cameras into a single interface? Are you concerned that your security system is only effective if each camera is operational? Do you have more than one security camera but wish you could view them all from one location?

If any of these questions apply to you, then the Blink Sync Module may be for you.

We put together this complete guide showing you how to set it up, troubleshoot issues, and more.

Here's what we cover:

What Is A Blink Sync Module 2, And What Does It Do?

The Blink Sync Module is the boss of all your Blink cameras, doorbell, and home security system. It’s a little device that connects all your cameras to one IP address, so you don’t have to deal with many different ones. Plus, you can even hook up a USB flash drive for local storage of your video files. Remember that the storage capacity depends on the flash drive you use.

And let me tell you, the latest and greatest version is the Blink Add-on Sync Module 2. It was just released on January 28th, 2021. You’ll find the Blink Sync 2 module, a wall DC power supply, a USB-A to Micro-USB cable, and an instructions booklet when you open the box.

Do I Need A Blink Subscription If I Have A Sync Module?

In order to be able to store your video clips to the cloud, you’ll need a subscription to Blink’s cloud storage plan, which is only $10 a month. But trust me, it’s totally worth it!

If you do not have a subscription, it will still work. You will just need to have a USB stick inserted into the module in order to store the video.

Accessing Blink’s Cloud Storage

Accessing your cloud storage is done through the Blink app. Just tap the cloud icon on the home screen.

Blink Sync Module 1 Vs 2

Last year they dropped version two of the device, and it’s a total upgrade, like woah! They made a few tweaks to make it even better. Both modules can handle up to 10 cameras, but there are a couple key differences between the two. So, what’s the deal with Sync Module 1 and 2? What sets them apart?

  • Module 2 is faster and more responsive.
  • Module 2 adds local storage to the flash drive USB port.

Do You Need A Sync Module For Blink Doorbell, Outdoor Camera, Indoor Camera, Or Blink Mini??

Can A Blink Camera Work Without A Sync Module 2?

Yes. A Sync Module is not required. Technically, you do not need a sync module for your outdoor camera to work. However, it does provide a few benefits. First is simplicity: instead of having an IP address for every camera on your network and configuring each IP individually, you just have one address to deal with, and that’s it.

The second benefit is that the sync module will provide faster data streaming from the cameras to your phone/tablet/computer than the stable wifi connection. This works for Blink security cameras, Blink mini, XT2 outdoor cameras, video doorbell cameras, etc.

Blink Sync Module 2 Setup

Sync Module Showing Up On Blink App

Setting up the module is a quick and easy process. However, there are a few things to keep in mind before you start:

  • Module placement – the best location for your Sync Module is as close to equal distances from each camera as possible. It doesn’t have to be exact, but if you can find a viable place that is equally close to all cameras, you will get the best results.
  • Range – going along with the placement of the module, you should be aware of the range you can expect from it. The max range is around ~100 feet. If you place it close to your router, that should help increase the distance. So if you need to place your camera far away – on the other side of your house – this may not be the best option for you. This will be fine if you only need to place the unit close to the router or in a central spot in your home.

It’s just like adding a new bestie to your squad. You gotta scan that QR code and give it a cute name. And don’t worry. It’s as easy as setting up your Sync Module the first time.

Blink Move Camera To A Different System

Moving your Blink camera from one Sync Module to another is very easy. Simply delete it from the module and add it to the new one.

How Far Can Blink Camera Be Away From Sync Module?

The Blink Sync Module range is 100 feet. If you need more range, you can use a wifi extender, but I have never had the need to use one because 100 feet is plenty for me.

Delete Blink Sync Module

If you want to reduce the number of cameras you are using and no longer need a specific module, you can quickly delete it from your system.

  1. Open your Blink app.
  2. Tap on settings.
  3. Scroll down to System Settings and select the system that has the specific module you want to delete.
  4. Tap on the Sync Module.
  5. Tap Delete Sync Module.

Best Location For The Blink Sync Module

The best place to keep your Blink Sync Module is in a central location. Pick a place that has a good wifi signal. I prefer to keep mine right beside my internet router.

How Many Blink Sync Modules Do I Need?

Figuring out how many Sync Modules you need is very simple. You need one Blink Module for each group of 10 cameras that you install. so, if you plan on setting up 6 cameras around your home, you need one module. If you increase that number to 11-20 cameras, you will need two.

How To Reset Blink Sync Module

At some point, you may want to reset your sync modules due to them not working correctly or not showing up in the app. You can reset this by simply unplugging it from the power and then plugging it back in again. That should reset it.

If this does not resolve any issues, you can try using the reset button. The hard factory reset button can be found next to the flash drive’s USB port. You will need a paper clip to press the button. Hold it down for 5 seconds, and you should see a red flashing light, then blue flashing lights, and then a solid green light.

Blink Sync Module Red Light

If you are experiencing a solid red light on your Blink module, it means that there is no internet connection. Check your router to make sure it is connected to the internet.

Blink Module Blinking Green Light

If your module is showing a flashing green light, it means that you are not correctly connected to the internet. We have a complete article on what to do when it is blinking green.

Other Blink Sync Module Lights Meanings

  • Blinking blue light – the camera is connected, but the connection is poor. This may be because the camera is too far away from the module.
  • Solid blue light only – your device has been reset and ready to connect to your network.
  • No lights – no power. Plug it in!

Here is a list of some of the most common issues and how to resolve them if they happen to you:

An Issue That I Encountered – IP Conflict

Setting up the cameras themselves was a piece of cake and everything seemed to work great for a few days. But, just out of the blue on day, I ran into a bit of trouble.

The camera went offline due to an IP conflict with another device on my wifi network.

I turned everything off and on again. I restarted my router, unplugged all my devices, and even did a little rain dance for good measure.

And you know what? It worked! After resetting everything, I was able to set up the Sync Module without a hitch. It was like magic.

From then on, the Blink system worked like a charm.

Blink Camera Won’t Connect to Sync Module

Suppose your camera or other devices aren’t connecting. In that case, the first thing you should try is giving ’em an excellent old-fashioned reset. Just unplug ’em and plug ’em back in. It’s like giving them a little wake-up call. Most of the time that’ll fix the problem.

If that doesn’t trick, try moving your devices closer together like a little family reunion. See if that helps. If that still ain’t working, try using a different wifi network. Your current one may be too picky.

If none of these options work, you might want to give support a call. They’re like IT wizards and will help you out in no time. But before you do, ensure you’ve tried all these steps, so you don’t look like a total tech novice.

Keeps Going Offline 

If the module drops off the internet periodically, I would first make sure that you are close enough to the router.

If this does work, the next step is to ensure that the wifi connection is actually dropping and not something else causing the disconnect issue. To do this, I recommend that you first disconnect from wifi on the module itself and reconnect to it.

To read more about solving this issue, take a look at our Blink Sync Module offline article.

Already Registered to a Different Account 

If your Sync Module is already registered to a different account, you will need to contact support to help resolve this issue. To get them, open the app and go to settings > help > contact us > submit a ticket. They will send you a confirmation email so that you can verify your account before helping you out further.

If you know what account it is assigned to and know someone that has access to it, you may be able to resolve the issue yourself by asking them to remove it from their account.

We have a more detailed instruction article on Sync Modules that are already registered to a different account here.

Won’t Reset with the Reset Button

If the reset button is not working, the only other option is to unplug it and then plug it back in.

Blink Camera to Sync Module Signal Is Weak

Having trouble getting a solid connection between your devices? Don’t sweat it. It’s probably just because they’re a little too far apart. Try moving your camera closer to the router and see if that helps. If not, give a different wifi a shot. It might be the ticket.

Blink Sync Module Data Is Bad

Suppose your videos or data are acting all corrupt. In that case, it’s probably because your sync module is having trouble connecting with the camera or the internet.

First things first, make sure you got a decent internet connection. You can check your router settings and see if there’s a better signal closer to you. If you’re too far from the router, try moving closer and see if that fixes the issue.

But if it ain’t working, you might wanna look into getting a new internet connection. And if you’re using a flash drive, try switching it up and see if that helps.


Why Do I Need a Blink Sync Module?

The main reason to get a Blink Sync Module is to centralize all of your security cameras into one easy-to-use application on your mobile device or computer.

You can also use this to store all your security camera recordings for later viewing as well.

Does Blink Camera Connect to Wifi or Sync Module?

It kind of connects to both. The Sync Module connects to wifi, and then the camera connects to the Sync Module.

How Many Blink Cameras per Sync Module?

You can connect up to 10 cameras per module.

Can I Use Blink Camera Without Sync Module?

Yes, you can use the Blink camera without a Sync Module. So no, you do not need one. However, you will be limited to how many security cameras you can connect with it at one time, as well as not being able to view all of them at once in the mobile app.

You will also have to manually back up your recordings to a USB drive or other local storage location instead of being able to automatically upload them to cloud storage like you can with a synced system.

Can You Use 2 Blink Sync Modules?

Yes, you can add a second Sync Module if you get to a point where your home has more than 10 cameras.

Does the Blink Sync Module Need to Stay Plugged In?

There are a couple different ways that you can power the module. First, you can use the power supply that was included with the unit and plug it into the wall. In this case, yes, you will need to keep it plugged in.

However, if it is close to a router, you can also plug it into the router with the USB cable, and it will be powered that way instead.

Can I Move Blink Camera to a Different Sync Module?

Yes, you can move the cameras to different modules if you change your mind about where to place them or if you have more than one home and want to place different ones in each location.

Can I Unplug My Blink Sync Module To Move It?

Yes, you can unplug the module at any time if you want to move the cameras to a different location or if you just need to charge the battery back up again. But it is not going to work without power.

Does the Sync Module Come With the Blink Camera

No, the Sync Module does not come with the camera.

Can You Use It Without A Blink Cloud Subscription?

Yes, you can use the Sync Module without a subscription. However, the footage gets transferred to the cloud with a subscription. It will be stored locally on the flash drive without a subscription.
