==What is it?==<br />
[[Home]] appliance to control other [[Amazon]] [[Blink]] devices.<br />
<br />
According to the manufacturer:<br />
"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 [https://support.blinkforhome.com/en_US/faq-sm/sync-module-2-faqs 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."<ref>[ https://support.blinkforhome.com/en_US/faq-sm/sync-module-2-faqs]</ref><br />
<br />
==What can it do?==<br />
<br />
*Control Blink devices (cameras, doorbells, etc) from the Blink mobile app<br />
*Connect up to 10 of any Blink Outdoor 4, Wired Floodlight, Outdoor and Indoor (all models), XT2, XT, Video Doorbell*, and Mini* cameras.<br />
*Support local video storage for up to 10 Blink cameras.<br />
*Record and store motion clips when you insert a USB flash drive (up to 256 GB).<br />
