A Sync Module is a hub that plugs into an electrical outlet to relay commands and network details to devices in the system it manages. It connects to your Wi-Fi network to handle activity for up to ten Blink devices. The Sync Module 2 and Sync Module XR enable you to save clips without a subscription, with eligible devices (Blink Outdoor 4, Wired Floodlight, Video Doorbell, Blink Indoor and Outdoor 3rd Gen and Mini cameras). They also improve convenience for scheduling and arms a group of devices at once. For an optimal experience, it's recommended to use a Sync Module with Blink devices.

Sync Modules provide the following benefits:

• Connects up to ten of any Blink Outdoor 4, Wired Floodlight, Outdoor and Indoor (all models), Video Doorbell, Mini, Mini 2, XT2 and XT cameras in a single system.
• Supports Local Storage for up to ten eligible Blink cameras on a system when using a USB drive (up to 256 GB – sold separately) for Sync Module 2, or a MicroSD card (up to 256 GB – sold separately) for Sync Module XR.

The Blink Wired Floodlight, Video Doorbell and Mini cameras do not require a Sync Module. These devices are capable of creating and managing their own systems, or can be added to existing systems that use a Sync Module. 

Note: When a Video Doorbell is not on a Sync Module or connected to chime wiring, it will operate in Event Response mode.
