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."[1]
What can it do?
- 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.
- Record and store motion clips when you insert a USB flash drive (up to 256 GB).
