To add a camera or Sync Module, you’ll need to enter its serial number either manually or using your camera to scan a QR code. To scan a QR code, the Blink app requires permission to access the camera on your mobile device. You can learn how to find the serial number and QR code of your device here.

If you experience problems scanning the serial number after granting this access, try the following to resolve the issue.

• Position your mobile device closer to or farther away from the QR code on your Blink device.
  It’s sometimes necessary to experiment with different distances and angles between your Blink device and camera lens to obtain optimal focus to scan the QR code.
  
  
• Adjust the brightness on your mobile device.
  If the brightness on your device is set too high or low, you may experience problems scanning the code. For example, if you’re in a well-lit setting, try increasing the brightness or lower it when in a darker environment.
  
  
• Disable ‘Dark Mode’

  iOS 1. Open Settings > Display & Brightness. 2. Select ‘Light’ to turn off Dark Mode. You can also turn off Dark Mode from the Control Centre.

  Android 1. Open the Settings app. 2. Click ‘Display’ and then toggle ‘Dark theme’ off. You can also turn off the Dark theme from the Quick Settings.

  
  
• Move to an evenly lit area.
  You’ll have greater success scanning the QR code in evenly lit environments without bright lights or direct sunlight.
  
  
• If using a mobile phone, try cleaning the camera lens or using a tablet with a larger screen.
  
  
• Scan the QR code on the Blink box label, which may produce better results.
