Overview
The Blink Sync Module 2 is the small plug-in hub that links battery-powered Blink cameras to your Wi-Fi and the Blink app. It talks to the cameras over Blink's own low-power 900 MHz radio and to your router over 2.4 GHz Wi-Fi. That's how cameras like the Outdoor 4 get up to two years from their batteries. It also has a USB port for saving clips to a flash drive without a subscription.

Error Codes
What the lights mean
| Lights | Meaning |
|---|---|
| Solid blue only | Starting up |
| Blinking blue, solid green | Ready to pair (setup mode) |

From Blink's LED guide; Sync Module (1st gen) and Sync Module 2 use the same patterns.
Troubleshooting
Sync Module offline
Blink lists three common causes: a power interruption, a Wi-Fi change such as a new password, and interference from mesh pods or extenders. Work through these in order:
- Check that the Wi-Fi password hasn't changed since you set the module up.
- Restart the router: unplug it for 30 seconds, then plug it back in.
- Restart the Sync Module: unplug it for 10 seconds. Solid blue and solid green means it's back.
- Re-enter the Wi-Fi password for the module in the Blink app.
- Turn off mesh pods or extenders so only the main router is on. Reconnect them once the module is online.
- If it still won't connect, delete the Sync Module in the app and add it again. Factory reset only as a last step.
Placement matters. Blink suggests the same room as the router, but not right next to it, and away from obstructions. The cameras then need to reach the module over the 900 MHz link, so a central spot helps both.
Clips not saving to the USB drive
- Use a drive between 1 GB and 256 GB with at least 375 MB free.
- A full or faulty drive stops clips saving; check the drive's status in the app.
Compatible Peripherals
- Cameras: Outdoor 4, Outdoor, Indoor, XT2, XT, and the Video Doorbell.
- Storage: Blink USB flash drive or any compatible USB drive.
Installation Notes
- Plug the module into a wall outlet indoors, in the same room as the router, but not right next to it.
- Add it in the Blink app first, then add cameras to it.
- It needs 2.4 GHz Wi-Fi.
- Plug in a USB flash drive (sold separately) if you want local clip storage.
FAQs
What does a blinking green light on a Blink Sync Module mean?
With solid blue, a blinking green light means the module is offline and trying to reconnect to its network. Check your internet, restart the router and the module, and re-enter the Wi-Fi password if it changed.
What size USB drive works with the Sync Module 2?
Blink specifies 1 GB to 256 GB, with at least 375 MB free.
Do I need a Sync Module 2?
Battery cameras such as the Outdoor 4 are designed to work through a Sync Module, which also gives you local storage. Some Blink plug-in cameras can work without one.
