How to manually update your mobile devices



We recommend that you always backup your data prior to updating your mobile device.


To get started with the Blink app, follow the instructions below:

With Blink, you have one user account with one email and one phone number. On log in and certain other actions, a verification number is sent to the mobile number or email address of the account.

Note: If you want to share your account with other users, learn more about setting up a second phone or device.

  1. Launch the Blink App and tap Create Account at the bottom of the screen.
  2. Select your country from the drop-down menu and tap Next.
  3. Your region is pre-selected based on your IP address. Confirm your region and tap OK.
  4. Enter a valid email address, and tap Next.
  5. Create a password and tap Create Account. The password requirements are listed at the bottom of the screen. Tap the eyeball icon if you want to view what you are typing.
  6. Complete the multi-factor authentication (MFA) process. Learn more about multi-factor authentication.

Multi-factor authentication steps

Verify your email address

Enter the PIN from the email we sent you and tap Verify.

  • PIN codes are valid for 40 minutes. 
  • If you haven't received the code after 90 seconds, tap Resend PIN Code.

Verify your phone number

Tap the phone number entry line to bring up a keypad.
Enter the phone number you wish to use for device verification and tap Next.

Optional: Select your country code by tapping the flag icon next to the phone number entry line.

If you prefer to not use SMS, the PIN code can be read to you by an automated voice call.
To choose this option, under Receive code by: select Voice call and tap Next.



The SMS text option is for use with mobile phones and will not work with landline phone numbers. Blink uses this number to associate your device with the Blink app to ensure the person making changes is you. Your information is private and will not be used for any additional purposes or shared with third parties.

Learn more why we need your phone number. Contact Customer Service if you don't have a phone number.

A SMS text message containing the PIN code is sent to the phone number, and you are shown another PIN entry screen.

Enter the PIN from the SMS text message we sent you and tap Verify.

  • PIN codes are valid for 40 minutes. 
  • If you haven't received the code after 90 seconds, tap Resend PIN Code.

When the phone verification step is complete, you are prompted to link your new Blink account to your Amazon account by tapping Link Accounts. If you don't want to link your account, select Skip to be sent to the Home screen without linking your accounts.

Note: This is an optional step, but we highly recommend linking your accounts at this time. Learn more about the benefits of linking your accounts.

Sign into your existing Amazon account. You will need to know your Amazon login email address and password. Once the link is established between accounts, tap Done.


2. Optional: Add your Sync Module

If you already have a Sync Module added to your system, skip to the next step.

How to install a Sync Module

Blink recommends using the video doorbell with a Sync Module for the best experience. It's important to add the Sync Module to your system first, and then add the device. Make sure to set up the Sync Module near to where you will be mounting the doorbell, for the most reliable setup of both devices.

After installation, you can use the Blink app's signal strength indicator to help choose a location if you wish to move the Sync Module.

Add a Sync Module and create a system

  1. From the Home screen, tap the + icon to add a device.

  2. On the Add Device screen, tap Sync Module.

  3. Scan the QR code on the back of the Sync Module or enter your Sync Module's serial number manually.
    Note: The Blink app may ask permission to access the camera on your mobile device in order to scan the QR code. If it asks, select Allow.

  4. Once the serial number is recognized, you are asked to create a new system. Tap the text entry box and provide a unique name for your system. If you have other existing systems, this name must be different from other system names you may have in your Blink account. Tap Continue after your new system name is entered.

  5. The Add Sync Module screen will instruct you to plug in your Sync Module and then wait for the light pattern of blinking blue and steady green.
    Tap Discover Device when you see this pattern on your Sync Module.

    Note: If you don't see the blinking blue light pattern, then you may need to reset the Sync Module. Learn more about how to reset the Sync Module.

  6. In order to connect to your network, the Blink app uses your mobile device to first connect to the Sync Module's temporary Wi-Fi network. It's named “BLINK-_ _ _ _" where the last 4 digits are from your Sync Module's serial number. Tap Join.

  7. After joining is successful, you are asked to join your local Wi-Fi network. Enter the Wi-Fi password and tap Join.
    • The Add Sync Module screen displays 2.4 GHz Wi-Fi networks within range. If you do not see your local Wi-Fi network, tap Refresh List at the bottom of the screen. The Sync Module stores network information for devices that are added to its system. Learn more about how to troubleshoot Wi-Fi connections.

  8. When your Sync Module has been added to your new system, you will receive a completion screen. Tap Done to finish the process. You're now ready to add your new camera.
    The new system name displays at the top of your Home screen and you will also see the Sync Module. A cloud icon settings icon  with a green connection line shows the Sync Module is successfully communicating with the Blink servers.

Installation options for the Blink Video Doorbell

The Blink Video Doorbell can be installed in three ways.

Wired Installation
The Video Doorbell is powered by two, size AA 1.5 volt lithium non-rechargeable batteries.
Connect existing doorbell wiring (16 - 24 VAC) to activate your home's doorbell chime. It works with most mechanical or digital chimes.
Connect a Sync Module to increase battery life up to 2 years of normal operation.
This installation type, combined with a Blink Subscription Plan, allows full functionality of the Blink Video Doorbell.

Wire-free Installation
The Video Doorbell is powered by two, size AA 1.5 volt lithium non-rechargeable batteries.

6. Final steps

Congrats, you've completed adding the doorbell to your Blink system! 

There's a few optional steps left to do.

Setting your camera name and thumbnail

This articles describes how to change your camera name and refresh the thumbnail image.

When you add a new camera, the camera name and image are not set up. Your camera's device serial number (DSN) displays as the camera name. The thumbnail image (your camera's view) will be blue. To change the name of your camera or add a thumbnail picture, follow the steps below.

Change the camera name

  • To find Device Settings, tap the More buttonsettings icon at the bottom right of the device's thumbnail image.
  • From the Device Setting screen, select General Settings.
  • Next, tap the camera's name to enter the new name (for example, back porch). Once you enter the new camera name, tap Save.

Note: When you update the name of your camera, clips recorded prior to the name change will appear in your Clip List as that previous name.

Refresh thumbnail

From the Home Screen, tap the More buttonsettings icon and select Refresh Thumbnail. The camera takes a screenshot of the current live view and replaces the blue image with this screenshot. The thumbnail remains the same until you refresh it using Refresh Thumbnail. Learn more about using the Blink app. 

Note: This process doesn't apply to the Video Doorbell when it's in Event Response Mode, since the thumbnail is updated automatically each time the doorbell ringer button is pressed or a motion event occurs. Learn more about Event Response Mode.


Helpful tips

If your doorbell is not found, an error screen appears and you are invited to retry. Tap Retry.

The doorbell notifies you it is ready to be added when the ring around the doorbell button flashes a red LED.

There are two ways to reset the doorbell.

  1. (Preferred) Remove the batteries for five seconds, replace the batteries, then wait for the red LED to blink.
  2. (Not recommended) Factory Reset - Press and hold the reset button (located on the back of the doorbell) until the red light flashes.

Device Settings

Use Device Settings to make other changes to your doorbell, such as adjusting your chime volume, motion detection sensitivity, and speaker volume.
From the Home screen on your doorbell's thumbnail, tap More  and select Device Settings . Learn more about how to adjust device settings.

If you do not see LED lights and you are sure that the batteries are new, please contact Customer Support.
