Blink SyncModule 2

What is it?

Home appliance to control other Amazon Blink devices.

According to the manufacturer: "The Sync Module is a hub that plugs into an electrical outlet to relay commands and network details to devices in the system it manages. The Sync Module 2 requires a power outlet and is connected to your always-on Wi-Fi network to handle activity for up to ten Blink devices. This extends camera battery life, saves clips without a subscription, improves convenience for scheduling, and arms a group of devices at once."

• Control Blink devices (cameras, doorbells, etc) from the Blink mobile app
• Connect up to 10 of any Blink Outdoor 4, Wired Floodlight, Outdoor and Indoor (all models), XT2, XT, Video Doorbell*, and Mini* cameras.
• Support local video storage for up to 10 Blink cameras.
